在济南的城市建设进程中，工地大门是每个建筑工地的重要组成部分，它不仅是工地的出入口标志，更在安全管理、形象展示等方面发挥着关键作用。从尺寸规格到制作样式，再到严格的管理规定，济南工地大门有着一套完整且细致的要求。

In the process of urban construction in Jinan, the construction site gate is an important component of every construction site. It is not only the entrance and exit sign of the construction site, but also plays a key role in safety management, image display, and other aspects. From size specifications to production styles, and then to strict management regulations, Jinan construction site gates have a complete and detailed set of requirements.

尺寸规范：保障通行与安全

Dimensional specifications: ensuring passage and safety

济南工地大门的尺寸设定有着明确的标准，以适配各类施工场景。在宽度方面，通常要求在 5 米以上，这是为了确保大型施工车辆，如混凝土搅拌车、渣土车等能够顺利进出。这些大型车辆体积庞大，只有足够宽的大门才能保证它们通行顺畅，避免因通道狭窄而造成刮擦、拥堵等情况，进而保障施工材料的及时运输和施工进度的正常推进。

The size setting of the gate of Jinan construction site has clear standards to adapt to various construction scenarios. In terms of width, it is usually required to be at least 5 meters to ensure the smooth entry and exit of large construction vehicles such as concrete mixer trucks and dump trucks. These large vehicles have a huge volume, and only wide enough doors can ensure their smooth passage, avoiding situations such as scratches and congestion caused by narrow passages, thereby ensuring the timely transportation of construction materials and the normal progress of construction progress.

而在高度上，一般介于 2.5 米至 4 米之间。这个高度范围既能满足常见建筑材料的运输需求，比如较长的钢梁、大型预制构件等，又考虑到了施工场地内一些机械设备的高度限制，同时也不会因过高而影响整体的稳定性和安全性。例如，当进行高层建筑物施工时，需要吊运大型建筑材料，合适高度的大门能让这些材料顺利进出工地。

In terms of height, it is generally between 2.5 meters and 4 meters. This height range can meet the transportation needs of common building materials, such as longer steel beams, large prefabricated components, etc., while also considering the height limitations of some mechanical equipment in the construction site. At the same time, it will not affect the overall stability and safety due to excessive height. For example, when constructing high-rise buildings, it is necessary to lift large building materials, and a gate of appropriate height can allow these materials to enter and exit the construction site smoothly.

制作样式：实用与美观兼具

Production style: combining practicality and aesthetics

无门楼式大门：这类大门结构相对简洁，门扇通常采用方钢焊接框架，再在表面铺设彩钢板。以常见的尺寸为例，门扇宽 6 米 ×1.95 米，这种规格能满足大多数小型车辆和人员的日常进出。门柱一般为 0.8 米 ×0.8 米，可以是砖砌结构，完成后进行抹灰、刮白处理，并喷上蓝漆白字，起到醒目的标识作用；也可用型钢制作，增强其坚固性。在门柱两侧，往往会各配备一盏景观灯，不仅在夜间为大门区域提供照明，还能提升工地的整体形象。

Gateless style gate: This type of gate has a relatively simple structure, and the door leaf is usually made of square steel welded frame, with colored steel plates laid on the surface. Taking the common size as an example, the door leaf is 6 meters wide by 1.95 meters, which can meet the daily entry and exit needs of most small vehicles and personnel. The pillar is generally 0.8 meters by 0.8 meters and can be a brick structure. After completion, it is plastered, scraped white, and sprayed with blue paint and white letters to serve as a prominent identification; It can also be made of steel sections to enhance its rigidity. On both sides of the gatepost, there is often a landscape light installed, which not only provides illumination for the gate area at night, but also enhances the overall image of the construction site.

有门楼式大门：相比无门楼式，有门楼式大门更具视觉冲击力，也更能体现企业的品牌形象。门柱尺寸一般为 800×800mm，采用砖砌后进行抹灰、刮白，并喷蓝底漆白字，突出信息展示。门头则是其亮点所在，通常长 7.6 米 × 宽 0.8 米 × 高 1 米，使用方圆型钢制作框架，再覆盖广告布或者 0.5mm 以上金属板材进行喷绘，以蓝底白字居多，展示企业名称、项目名称、宣传标语等内容，在城市中形成一道独特的风景线，同时也起到了一定的广告宣传效果。

Gated style entrance: Compared to the gateless style, a gatehouse style entrance has a more visual impact and better reflects the brand image of the enterprise. The size of the door post is generally 800 × 800mm, which is built with bricks and then plastered, scraped white, and sprayed with blue primer and white text to highlight the information display. The storefront is its highlight, usually measuring 7.6 meters in length, 0.8 meters in width, and 1 meter in height. It is made of square steel frame and covered with advertising cloth or metal sheet with a thickness of 0.5mm or more for spray painting. The blue background and white text are mostly used to display the company name, project name, promotional slogans, and other content, forming a unique landscape in the city and also playing a certain advertising and promotional role.

安装要点：稳固与精准

Installation points: stability and precision

地基处理：在安装工地大门前，首先要对地基进行处理。方开挖后，需采用立式汽油机压实地基土层，确保压实系数大于或等于 95%，以保证地基的稳定性。若两柱脚侧墙泥土松动，必须立模处理，模板要具备足够的刚度、强度和稳定性，严格按照现行有关规范操作，确保地基的形状、尺寸和截面尺寸准确无误。模板支设完毕后，要进行二次施工放样，精确确定门柱和导轨的位置，为后续埋件与导轨的焊接做好充分准备。

Foundation treatment: Before installing the gate of the construction site, the foundation must be treated first. After excavation, a vertical gasoline engine should be used to compact the soil layer of the foundation, ensuring that the compaction coefficient is greater than or equal to 95% to ensure the stability of the foundation. If the soil on the side walls of the two column bases becomes loose, formwork must be erected for treatment. The formwork must have sufficient rigidity, strength, and stability, and must be operated strictly in accordance with current relevant specifications to ensure the accuracy of the shape, size, and cross-sectional dimensions of the foundation. After the template installation is completed, a secondary construction layout should be carried out to accurately determine the positions of the door posts and guide rails, in order to make sufficient preparations for the welding of subsequent embedded parts and guide rails.

埋件与导轨安装：在 10 米的入口段，每隔 2 米需用电锤在原石混凝土基础两侧钻孔，安装 15 厘米长的膨胀螺栓（若在没有混凝土垫层的区域，则使用 22 根长直径钢筋，并将其推到地下土层进行锚定），然后焊接 10 毫米厚、100mm×60mm、高 460 毫米的方形管道，用于安装和固定导轨。三柱基础在四个角处用钢筋锚固，再与嵌入式框架焊接。特别要注意的是，所有埋件的顶高应保证导轨槽钢放置后的顶高达到标准高度且处于水平面上，同时将导轨和两柱基础座的钢板牢固焊接，确保整体结构的稳固性。

Installation of embedded parts and guide rails: At the entrance section of 10 meters, an electric hammer is used to drill holes on both sides of the original stone concrete foundation every 2 meters, install 15 centimeter long expansion bolts (if there is no concrete cushion layer in the area, 22 long diameter steel bars are used and pushed to the underground soil layer for anchoring), and then weld a 10mm thick, 100mm x 60mm, 460mm high square pipe for installing and fixing the guide rails. The three column foundation is anchored with steel bars at the four corners and welded to the embedded frame. It should be noted that the top height of all embedded parts should ensure that the top height of the guide rail channel steel after placement reaches the standard height and is on a horizontal plane. At the same time, the steel plates of the guide rail and the two column foundation seats should be firmly welded to ensure the stability of the overall structure.

大门安装：以常见的济南工地大门为例，门叶长 11 米，高 2.5 米。外框采用 5mm 厚、120mmx60mm 的扁钢焊接而成，内框焊接壁厚 5mm、长宽 60mmx6mm 的方钢管，共 21 根，间距 500mm，以增强门扇的强度。门扇面板用 0.78mm 厚的彩钢板用铆钉固定在门框表面，起到防护和美观的作用。在门下高度 200mm、宽度 120mm 的钢板两侧固定焊接直径 160mm、厚度 60mm 的四个钢轮，用于支撑门扇在导轨上滑动；门框上部用 50mm×50mm×5mm 角钢作为支架和门柱焊接，并固定八个直径 80mm、高 70mm 的小橡胶轮，用以固定门扇。由于闸门重量较大，安装时需要使用 20 吨汽车吊，先将门扇吊起，由操作人员焊接闸门底轮，使其在导轨上前后滑动并固定，调试成功后再对门上小轮进行调试固定，焊接时要锁住车门固定装置。安装完毕后，对各焊接点进行防腐处理，刷防锈漆三遍，然后对闸门进行清洗，最后按要求在门柱、大门的正面和背面刷漆，正面可刷公司形象图案设计，提升工地整体形象。

Gate installation: Taking the common Jinan construction site gate as an example, the gate leaf is 11 meters long and 2.5 meters high. The outer frame is welded with 5mm thick, 120mmx60mm flat steel, and the inner frame is welded with 21 square steel pipes with a wall thickness of 5mm and a length and width of 60mmx6mm, spaced 500mm apart, to enhance the strength of the door leaf. The door panel is fixed to the surface of the door frame with 0.78mm thick color steel plate and rivets, providing protection and aesthetics. Four steel wheels with a diameter of 160mm and a thickness of 60mm are fixed and welded on both sides of a steel plate with a height of 200mm and a width of 120mm under the door to support the sliding of the door leaf on the guide rail; The upper part of the door frame is supported by 50mm × 50mm × 5mm angle steel and welded to the door post, and eight small rubber wheels with a diameter of 80mm and a height of 70mm are fixed to fix the door leaf. Due to the large weight of the gate, a 20 ton truck crane is required for installation. The door leaf is first lifted, and the operator welds the bottom wheel of the gate to slide forward and backward on the guide rail and fix it. After successful debugging, the small wheel on the door is adjusted and fixed, and the door fixing device is locked during welding. After installation, anti-corrosion treatment should be carried out on each welding point, and anti rust paint should be applied three times. Then, the gate should be cleaned, and finally the front and back of the door post and gate should be painted as required. The front can be painted with the company's image design to enhance the overall image of the construction site.

管理规定：严守安全与秩序

Management regulations: Strictly abide by safety and order

人员管理：施工单位需安排专门的管理人员，24 小时值班负责大门的开闭、进出人员和车辆的管理以及安全检查等工作。这些管理人员必须接受相关安全管理和技能培训，考核合格后方可上岗。上岗时要佩戴统一的工作服和工作证，便于识别和管理。他们要严格执行检查、登记、记录等程序，对所有进出工地的人员进行身份验证和安全检查，杜绝无关人员进入工地，保障施工区域的安全。

Personnel management: The construction unit needs to arrange dedicated management personnel who are on duty 24 hours a day to be responsible for the opening and closing of the gate, the management of personnel and vehicles entering and exiting, and safety inspections. These management personnel must receive relevant safety management and skill training, and pass the assessment before they can take up their posts. When on duty, it is necessary to wear uniform and work permit for easy identification and management. They must strictly implement inspection, registration, recording and other procedures, verify the identity and conduct safety checks on all personnel entering and leaving the construction site, prevent unrelated personnel from entering the construction site, and ensure the safety of the construction area.

设施管理：工地进出口处必须配备相应数量的监控设备，并且保证设备能正常工作，以便实时监控大门区域的情况，及时发现和处理异常事件。同时，要安装有效的防护设施，如可靠的门禁系统，控制人员和车辆的进出权限；车辆限高限宽设施，防止超高超宽车辆损坏大门或影响施工安全；速度减速带，提醒车辆减速慢行；指示牌和警示标识，引导车辆和人员安全通行。

Facility management: The entrance and exit of the construction site must be equipped with a corresponding number of monitoring devices, and ensure that the devices can work normally, in order to monitor the situation in the gate area in real time, detect and handle abnormal events in a timely manner. At the same time, effective protective facilities should be installed, such as reliable access control systems, to control the entry and exit permissions of personnel and vehicles; Vehicle height and width restriction facilities to prevent vehicles with excessive height and width from damaging the gate or affecting construction safety; Speed bumps remind vehicles to slow down and travel slowly; Signboards and warning signs guide vehicles and personnel to safely pass through.

车辆管理：工地进出口处需设置专门的车辆通行区域，对进出车辆进行合理的安全管控。所有进出车辆必须在大门管理处进行登记，包括车辆信息、进出时间、运输货物等。土石方运输车辆较多时，要结合实际情况在施工现场设置车辆拐点，提高运输效率。现场自卸汽车司机要持证上岗，并定期检查和维护车辆的制动和转向系统，确保行车安全。每天还要对进场道路进行清扫，保证道路的清洁、畅通，避免因道路杂物影响车辆通行和施工环境。

Vehicle management: A dedicated vehicle passage area should be set up at the entrance and exit of the construction site to provide reasonable safety control for incoming and outgoing vehicles. All vehicles entering and exiting must be registered at the gate management office, including vehicle information, entry and exit time, transported goods, etc. When there are many vehicles transporting earth and stone, vehicle turning points should be set up at the construction site according to the actual situation to improve transportation efficiency. On site dump truck drivers must hold certificates and regularly inspect and maintain the vehicle's braking and steering systems to ensure driving safety. Every day, the access roads must be cleaned to ensure cleanliness and smoothness, and to avoid the impact of road debris on vehicle traffic and construction environment.
