基坑临边护栏从字面意义上可以看出，它被用作基坑的护栏，主要起到保护的作用。防止人或物体掉入基坑中并对其自身或三方造成损害。下面来讲讲基坑临边护栏施工方法和验收事项。

It can be seen from the literal sense that the guardrail at the edge of the foundation pit is used as the guardrail of the foundation pit, mainly for safety protection. Prevent people or objects from falling into the foundation pit and causing damage to themselves or three parties. Next, we will talk about the construction methods and acceptance items of the guardrail at the edge of the foundation pit.

基坑临边护栏施工方法

Construction Method of Side Fence of Foundation Pit

现场浇筑地基，并人工开挖基坑。对于无法手动挖掘的岩石部分，请使用风镐或风枪开凿浅孔，并辅以弱爆破，开挖上部土质坑壁放坡，下部岩石坑壁垂直。

Cast the foundation on site and excavate the foundation pit manually. For the rock part that cannot be excavated manually, use an air pick or air gun to drill shallow holes, supplemented by weak blasting, excavate the upper soil pit wall for slope, and the lower rock pit wall is vertical.

基坑开挖坡度的坡度取决于地面，基坑的大小应符合基坑的轮廓。在安装混凝土基础之前，应及时检查基础坑的大小，平面位置以及地面的平坦度和紧实度，然后继续进行基础施工。

The slope of the excavation slope of the foundation pit depends on the ground, and the size of the foundation pit shall conform to the outline of the foundation pit. Before installing the concrete foundation, the size, plane position, flatness and compactness of the foundation pit shall be checked in time, and then the foundation construction shall continue.

基地检查：在对基础混凝土进行灌浆之前，对基坑进行隐蔽的工程检查。检查的内容是：基准面的位置和高度是否符合规格。基地的土壤质量是否符合规范，承载力是否满足规范要求。底座是否积水，碎屑，松散的土壤，以及是否清洁且平整。

Base inspection: Before grouting the foundation concrete, inspect the concealed works of the foundation pit. The inspection content is: whether the position and height of the datum plane conform to the specification. Whether the soil quality of the base meets the specification and whether the bearing capacity meets the specification requirements. Whether the base is free of water, debris, loose soil, and whether it is clean and flat.

基低处理：当基低是干燥土壤时，应将其润湿。在地基的设计高度下，过程土应填充一层砾石。当基底面是岩石时，应将其润湿并铺一层水泥砂浆。

Base low treatment: when the base low is dry soil, it should be wetted. At the design height of the foundation, the process soil shall be filled with a layer of gravel. When the base surface is rock, it shall be wetted and laid with a layer of cement mortar.

基坑护栏的验收注意事项

Precautions for acceptance of foundation pit guardrail

1、重量：验收期间需要随机检查产品的重量。重量通常是基坑防护网的重要标准之一。我相信每个人在购买时都会向制造商询问具体的重量，重量差通常为±0.5千克，超过此重量的原因。这种下降的原因需要制造商的具体询问。

1. Weight: The weight of the product shall be checked randomly during acceptance. Weight is usually one of the important standards of foundation pit protective net. I believe that everyone will ask the manufacturer about the specific weight when purchasing. The weight difference is usually ± 0.5kg, and the reason for exceeding this weight. The reason for this decline requires specific inquiries from the manufacturer.

2、表面处理：喷涂是异型基坑护栏的常用表面处理方法。检查时，要注意塑料层的均匀性和颜色是否鲜艳。护栏在装卸期间不可避免地会碰撞。一小部分表面磨损是正常现象，但不允许出现皮肤破裂现象。

2. Surface treatment: spraying is a common surface treatment method for special-shaped foundation pit safety barrier. When checking, pay attention to the uniformity of the plastic layer and whether the color is bright. Guardrails will inevitably collide during loading and unloading. A small part of the surface wear is normal, but skin fracture is not allowed.

3、焊接点：基坑护栏的焊接方法为两遍焊接和全焊，焊接点须牢固，且焊点不得裸露。

3. Welding point: the welding method of foundation pit guardrail is two times of welding and full welding, the welding point must be firm, and the welding point must not be exposed.

4、框架：验收时注意检查框架。框架不得弯曲或损坏。

4. Frame: pay attention to check the frame during acceptance. The frame shall not be bent or damaged.

基坑临边护栏在建筑工地中更为常见。它是根据基础建设位置按照基底标高和基础平面尺寸所开挖出来的土坑。它主要用于打地基，所以以上的内容就能发挥出大的作用了，您对此还有什么问题可以随时来我们网站//www.hongdaxinwuliu.com做咨询！

The side guardrail of foundation pit is more common in construction sites. It is an earth pit excavated according to the foundation construction location and the foundation elevation and foundation plane size. It is mainly used to lay foundation, so the above content can play a big role. If you have any questions about it, you can come to our website at any time //www.hongdaxinwuliu.com Consulting!
