Abstract

The invention relates to the field of building construction, in particular to an open cut tunnel waterproof construction method. The open cut tunnel waterproof construction method provided by the invention comprises the steps of 1) after an open cut tunnel outer formwork is removed, clearly cleaning sharp materials and sundries on concrete surfaces, flattening rough positions on the concrete surfaces and smearing exterior surfaces of lining to be flat and smooth by using cement mortar; 2) conducting open cut tunnel arch wall lining back waterproof layer construction, wherein interlayer humidity detection sensor groups are installed between layers and can communicate with an engineering control center; 3) conducting open cut tunnel inverted arch lining back waterproof layer construction, wherein interlayer humidity detection sensor groups are installed between layers and can communicate with the engineering control center. The novel open cut tunnel waterproof construction method provided by the invention has the advantages that the construction quality of the open cut tunnel construction method can be effectively improved, the construction efficiency is improved, the waterproof effect change situation can be found in time and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an open hole waterproof construction method. Background technique [0002] With the rapid development of my country's construction market, a large number of high-speed railways and super high-rise buildings have emerged, and foundation pit projects are common in areas with high groundwater levels, areas near reclamation, alluvial delta areas, and areas with complex geological conditions such as silt or quicksand. During the construction and use process, groundwater has caused great troubles to the project, especially the waterproof effect of open holes needs to be strengthened urgently. [0003] Based on the problems in the above analysis, the present invention proposes a waterproof construction method for open holes. Contents of the invention [0004] The purpose of the present invention is to solve the problems that the existing open hole waterproof constructio...
