丈量是现场施工的眼睛，是工程扶植中必不成少的一个环节。但工程中各个环节对丈量的要求是凹凸分歧的，防撞墙施工进程中对丈量的要求属在比**的一类。

Measurement is the eye of site ctruction and an indispensable link in engineering ctruction. However, the requirements for measurement are different in each link of the project, and the requirements for measurement in leyu����.txtthe ctruction process of anti-collision wall belong to a relatively high category.

支模前需要丈量来批改防撞墙根本标高，根本太高或太低都对今后的施工发生十分严重的影响。假如太高，则在安装模板时则必需把超出跨越部门凿失落，费时、吃力、花钱。假如太低则有可能使后期模板底部有空地，导致水泥浆流出，造成麻面的现象。
