Problems solved by technology

[0003] During the foundation pit construction, it is necessary to use measuring devices to measure the height and level of the foundation pit, but the existing measuring devices need to be placed on a flat ground, which is difficult to achieve in practice, and multiple devices are required for measurement, increasing the The workload of workers and the difficulty of operation, so we propose a laser level measuring device for foundation pit construction to solve the above-mentioned problems

Abstract

The invention belongs to the technical field of foundation pit construction, and particularly relates to a laser horizontal height measuring device for foundation pit construction. The problems that an existing measuring device needs to be placed on a flat ground, is difficult to realize practically, a plurality of devices are needed for measurement, and the workload of workers and the operation difficulty are increased are solved. According to the following scheme, the laser horizontal height measuring device comprises two bottom plates which are symmetrically arranged, a first fixing plate is fixedly connected to the tops of the bottom plates, a control assembly used for controlling the distance between the two bottom plates is arranged on one side of the first fixing plate, and supporting columns are fixedly connected to the tops of the bottom plates. A first adjusting assembly adjusts the level of a supporting plate, the device does not need to be placed on the flat ground any more, the height of a fixing box is adjusted through a second adjusting assembly to judge the height difference between two measuring points of the foundation pit, then the height in the foundation pit ismeasured through a laser range finder, the structure is simple, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of foundation pit construction, in particular to a laser level measuring device for foundation pit construction. Background technique [0002] The foundation pit is an earth pit excavated at the foundation design position according to the base level and foundation plane size. Before excavation, the excavation plan should be determined according to the geological and hydrological data, combined with the conditions of the nearby buildings, and the waterproof and drainage work should be done well. If the excavation is not deep, the side slope can be used to stabilize the soil slope, and the slope size is determined according to the relevant construction regulations. For those with deep excavation and nearby buildings, the foundation pit wall support method, shotcrete retaining wall method, and large foundation pit even adopt methods such as underground diaphragm wall and column-type bored pile interlocking to ...
