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

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(hù)欄施工方法

Construction Method of Side Fence of Foundation Pit

現(xiàn)場(chǎng)澆筑地基，并人工開(kāi)挖基坑。對(duì)于無(wú)法手動(dòng)挖掘的巖石部分，請(qǐng)使用風(fēng)鎬或風(fēng)槍開(kāi)鑿淺孔，并輔以弱爆破，開(kāi)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(kāi)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(shí)檢查基礎(chǔ)坑的大小，平面位置以及地面的平坦度和緊實(shí)度，然后繼續(xù)進(jìn)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(duì)基礎(chǔ)混凝土進(jìn)行灌漿之前，對(duì)基坑進(jìn)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?；氐耐寥蕾|(zhì)量是否符合規(guī)范，承載力是否滿(mǎn)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(shí)，應(yīng)將其潤(rùn)濕。在地基的設(shè)計(jì)高度下，過(guò)程土應(yīng)填充一層礫石。當(dāng)基底面是巖石時(shí)，應(yīng)將其潤(rùn)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(hù)欄的驗(yàn)收注意事項(xiàng)

Precautions for acceptance of foundation pit guardrail

1、重量：驗(yàn)收期間需要隨機(jī)檢查產(chǎn)品的重量。重量通常是基坑防護(hù)網(wǎng)的重要標(biāo)準(zhǔn)之一。我相信每個(gè)人在購(gòu)買(mǎi)時(shí)都會(huì)向制造商詢(xún)問(wèn)具體的重量，重量差通常為±0.5千克，超過(guò)此重量的原因。這種下降的原因需要制造商的具體詢(xún)問(wèn)。

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(hù)欄的常用表面處理方法。檢查時(shí)，要注意塑料層的均勻性和顏色是否鮮艷。護(hù)欄在裝卸期間不可避免地會(huì)碰撞。一小部分表面磨損是正?，F(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(diǎn)：基坑護(hù)欄的焊接方法為兩遍焊接和全焊，焊接點(diǎn)須牢固，且焊點(diǎn)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(yàn)收時(shí)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(hù)欄在建筑工地中更為常見(jiàn)。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(kāi)挖出來(lái)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(duì)此還有什么問(wèn)題可以隨時(shí)來(lái)我們網(wǎng)站http://www.zzaifang7.cn做咨詢(xún)！

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://www.zzaifang7.cn Consulting!
