基坑臨邊護欄從字面意義上可以看出，它被用作基坑的護欄，主要起到保護的作用。防止人或物體掉入基坑中并對其自身或三方造成損害。下面來講講基坑臨邊護欄施工方法和驗收事項。

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.

基坑臨邊護欄施工方法

Construction Method of Side Fence of Foundation Pit

現(xiàn)場澆筑地基，并人工開挖基坑。對于無法手動挖掘的巖石部分，請使用風(fēng)鎬或風(fēng)槍開鑿淺孔，并輔以弱爆破，開挖上部土質(zhì)坑壁放坡，下部巖石坑壁垂直。

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.

基坑開挖坡度的坡度取決于地面，基坑的大小應(yīng)符合基坑的輪廓。在安裝混凝土基礎(chǔ)之前，應(yīng)及時檢查基礎(chǔ)坑的大小，平面位置以及地面的平坦度和緊實度，然后繼續(xù)進行基礎(chǔ)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.

基地檢查：在對基礎(chǔ)混凝土進行灌漿之前，對基坑進行隱蔽的工程檢查。檢查的內(nèi)容是：基準(zhǔn)面的位置和高度是否符合規(guī)格。基地的土壤質(zhì)量是否符合規(guī)范，承載力是否滿足規(guī)范要求。底座是否積水，碎屑，松散的土壤，以及是否清潔且平整。

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.

基低處理：當(dāng)基低是干燥土壤時，應(yīng)將其潤濕。在地基的設(shè)計高度下，過程土應(yīng)填充一層礫石。當(dāng)基底面是巖石時，應(yīng)將其潤濕并鋪一層水泥砂漿。

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.

基坑護欄的驗收注意事項

Precautions for acceptance of foundation pit guardrail

1、重量：驗收期間需要隨機檢查產(chǎn)品的重量。重量通常是基坑防護網(wǎng)的重要標(biāo)準(zhǔn)之一。我相信每個人在購買時都會向制造商詢問具體的重量，重量差通常為±0.5千克，超過此重量的原因。這種下降的原因需要制造商的具體詢問。

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、表面處理：噴涂是異型基坑護欄的常用表面處理方法。檢查時，要注意塑料層的均勻性和顏色是否鮮艷。護欄在裝卸期間不可避免地會碰撞。一小部分表面磨損是正常現(xiàn)象，但不允許出現(xiàn)皮膚破裂現(xiàn)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、焊接點：基坑護欄的焊接方法為兩遍焊接和全焊，焊接點須牢固，且焊點不得裸露。

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：驗收時注意檢查框架。框架不得彎曲或損壞。

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

基坑臨邊護欄在建筑工地中更為常見。它是根據(jù)基礎(chǔ)建設(shè)位置按照基底標(biāo)高和基礎(chǔ)平面尺寸所開挖出來的土坑。它主要用于打地基，所以以上的內(nèi)容就能發(fā)揮出大的作用了，您對此還有什么問題可以隨時來我們網(wǎng)站http://m.48ad.com做咨詢！

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 http://m.48ad.com Consulting!
