基坑(keng)臨邊(bian)護(hu)欄(lan)又叫(jiao)基坑(keng)防(fang)護(hu)網(wang)、基坑(keng)防(fang)護(hu)欄(lan)、基坑(keng)臨邊(bian)防(fang)護(hu)欄(lan)、建(jian)筑(zhu)工(gong)地護(hu)欄(lan)等。在(zai)建(jian)筑(zhu)施工(gong)開始首要是(shi)挖(wa)地基把挖(wa)好的(de)基坑(keng)圍護(hu)起來，防(fang)止施工(gong)意外的(de)發(fa)生，確保(bao)在(zai)建(jian)筑(zhu)施工(gong)時無事(shi)故發(fa)生，保(bao)證施工(gong)進度正(zheng)常建(jian)設。

Foundation pit edge guardrail, also known as foundation pit protective net, foundation pit guardrail, foundation pit edge guardrail, construction site guardrail, etc. At the beginning of construction, the first priority is to excavate the foundation and enclose the excavated foundation pit to prevent construction accidents, ensure that no safety accidents occur during construction, and ensure the normal construction progress.

在(zai)安裝前(qian)的(de)(de)(de)(de)基坑(keng)臨邊護欄(lan)(lan)一般是建設形成(cheng)的(de)(de)(de)(de)較(jiao)低的(de)(de)(de)(de)磚或混凝(ning)土(tu)澆筑與防護欄(lan)(lan)使用機械膨(peng)脹螺(luo)栓、化學螺(luo)絲檢(jian)查(cha)和(he)(he)其他方法(fa)來中心(xin)支柱(zhu)鋼(gang)襯(chen)(chen)部分降低基礎直線(xian)。如(ru)果沒有(you)形成(cheng)較(jiao)低的(de)(de)(de)(de)墻(qiang)體底板(ban)，可以將鋼(gang)襯(chen)(chen)的(de)(de)(de)(de)長度直接(jie)埋(mai)在(zai)墻(qiang)內(nei)，并(bing)在(zai)墻(qiang)的(de)(de)(de)(de)養護期后正式施工(gong)。或者是提(ti)前(qian)做預制(zhi)件(jian)，將預制(zhi)件(jian)與預制(zhi)件(jian)焊接(jie)在(zai)柱(zhu)內(nei)。這樣(yang)的(de)(de)(de)(de)方法(fa)比螺(luo)栓鏈接(jie)更加牢固，但前(qian)提(ti)是假(jia)定的(de)(de)(de)(de)，施工(gong)時必須要注意直線(xian)和(he)(he)水平線(xian)，鋼(gang)柱(zhu)與鋼(gang)襯(chen)(chen)之間的(de)(de)(de)(de)距(ju)離(li)與設計(ji)尺寸一致，以保半成(cheng)品能(neng)與之相連(lian)。

Before installation, the edge guardrail of the foundation pit is generally constructed by pouring lower bricks or concrete and using mechanical expansion bolts, chemical screws for inspection, and other methods to solve the problem of lowering the foundation straight line of the steel lining part of the central pillar. If a lower wall bottom plate is not formed, the length of the steel lining can be directly buried inside the wall and officially constructed after the wall's curing period. Alternatively, prefabricated components can be made in advance and welded to the column. This method is more secure than bolted connections, but the premise is that during construction, attention must be paid to straight and horizontal lines, and the distance between the steel column and the steel lining should be consistent with the design dimensions to ensure that the semi-finished product can be connected to it.

在直線上(shang)畫上(shang)兩(liang)條平(ping)行線，使整個斷面作(zuo)為安(an)(an)裝(zhuang)和(he)調整的(de)基準，安(an)(an)裝(zhuang)后確(que)保(bao)基坑(keng)防(fang)護欄(lan)上(shang)下(xia)端平(ping)整。在工地建立(li)之前已經安(an)(an)裝(zhuang)基坑(keng)防(fang)護欄(lan)的(de)十(shi)字和(he)鋼(gang)襯，每個軸承的(de)加強部分也安(an)(an)裝(zhuang)到位。在現(xian)場施工時(shi)只需(xu)要將基坑(keng)防(fang)護欄(lan)襯墊與(yu)立(li)柱相連即可。

Draw two parallel lines on the straight line, making the entire section the benchmark for installation and adjustment. After installation, ensure that the upper and lower ends of the foundation pit protective fence are flat. Before the construction site is established, the cross and steel lining of the foundation pit guardrail have been installed, and the reinforcing parts of each bearing have also been installed in place. During on-site construction, it is only necessary to connect the foundation pit protective fence pad to the column.

基(ji)坑(keng)臨(lin)邊護欄是根據施工(gong)圖(tu)紙定制(zhi)而(er)成(cheng)，嚴(yan)格按圖(tu)施工(gong)，要(yao)求在出廠前進行串(chuan)聯(lian)組裝。產品在運施工(gong)現場后(hou)只需將(jiang)各立柱(zhu)的(de)(de)(de)(de)鋼襯插入穩定的(de)(de)(de)(de)基(ji)座中，根據使用(yong)部門的(de)(de)(de)(de)要(yao)求擴展布局。基(ji)礎打好完成(cheng)后(hou)將(jiang)使用(yong)特殊的(de)(de)(de)(de)螺栓將(jiang)每(mei)個基(ji)坑(keng)護欄適當的(de)(de)(de)(de)連接起來。為了提高抗風性和(he)惡意移動，穩定的(de)(de)(de)(de)底(di)座應固定在地(di)面上(shang)，膨(peng)脹螺栓部分應在地(di)面內。

The edge guardrail of the foundation pit is customized according to the construction drawings and constructed strictly according to the drawings. It is required to be assembled in series before leaving the factory. After the product is transported to the construction site, simply insert the steel lining of each column into a stable base and expand the layout according to the requirements of the user department. After the foundation is laid, special bolts will be used to properly connect each foundation pit guardrail. In order to improve wind resistance and malicious movement, a stable base should be fixed on the ground, and the expansion bolt part should be inside the ground.
