Micro-pile pre-stressed anchor cable composite soil nailing wall deep foundation pit supporting construction method
The invention discloses a micro-pile pre-stressed anchor cable composite soil nailing wall deep foundation pit supporting construction method. The construction method specifically comprises the following steps that S1, soil nailing wall construction is carried out, wherein the soil nailing wall construction specifically comprises the following steps that S101, a site is arranged, namely, the soilnailing wall construction site is leveled; S102, earth excavation is conducted, namely, earth excavation is conducted on the soil nailing wall construction; S103, slope trimming is conducted, namely,manual slope trimming is adopted, and the gradient is measured and controlled by measuring personnel; and S104, hole forming is conducted, namely, hole forming is conducted through an anchor rod engineering driller, and a cement paste retaining wall is pressed into a hole during hole forming. By adopting the micro-pile supporting scheme, slurry discharge can be reduced, relatively high environmental protection benefits are achieved, and meanwhile construction noise is lower than that of cast-in-place pile construction; the purpose of safe construction can be achieved under the condition that normal passage of the national highway is not blocked, a temporary guide road which needs to be built due to road blocking construction is omitted, meanwhile normal operation of the national highway during construction is guaranteed, and a guarantee is provided for a project to pass the rainy season smoothly.
本发明公开了微型桩预应力锚索复合土钉墙深基坑支护施工工法，该施工工法具体包括以下步骤：S1：土钉墙施工；土钉墙施工具体包括以下步骤：S101：整理现场，对土钉墙施工现场进行整平；S102：土方开挖，对土钉墙施工进行土方挖掘；S103：修坡，采用人工修坡，坡度通过测量人员测量控制；S104：成孔，采用锚杆工程钻机成孔，成孔时孔内压入水泥浆护壁；采用微型桩支护方案可减少泥浆排放，具有较大环保效益，同时施工噪声较灌注桩施工小；可在不阻断国道正常通行的情况下达到安全施工的目的，节省由于断路施工所必须修建的临时导行路，同时保证了施工期间的国道的正常运转，为工程顺利度过雨季提供的保障。
