Construction method for efficiently treating phyllite base rock surface

Abstract

The invention provides a construction method for efficiently treating a phyllite base rock surface, which comprises the following steps: S1, determining a construction position for excavation, and cleaning an excavated foundation surface; s2, geological sketching and excavation acceptance inspection are conducted on the cleaned foundation surface; s3, cushion layer concrete construction is carried out on the foundation surface after excavation and cleaning; s4, anchor rod construction is conducted, specifically, drilling is conducted on the solidified cushion layer concrete and phyllite through a drilling machine, and anchor rods are installed and fixed; s5, steel bars are manufactured and installed, a formwork is assembled, a water pump, a slag hopper and an air gun are used for cleaning rock debris generated during anchor rod construction, and then the formwork is assembled; s6, the bin surface is flushed, specifically, the bin surface is flushed through a water pump, and broken stones and the like generated in the construction process are flushed away; and S7, concrete is poured, and bedrock surface treatment is completed. According to the method, the mechanical indexes of the phyllite are prevented from being reduced, so that the foundation surface meets the design requirements, the manual cleaning workload is reduced, the working intensity is reduced, the construction efficiency is improved, the construction period is shortened, the labor cost is reduced, and the construction benefits are increased.

Description

technical field [0001] The invention belongs to the technical field of bedrock surface treatment construction, and in particular relates to a construction method for efficiently treating phyllite bedrock surfaces. Background technique [0002] Phyllite is easy to weather and disintegrate when exposed to water, which will quickly reduce the mechanical indicators such as rock strength and affect the quality of project construction. Especially when building a hydropower station, due to the special construction environment, it is necessary to treat the bedrock surface of phyllite to ensure subsequent construction. . The treatment process of the traditional phyllite bedrock surface before concrete pouring is as follows: cleaning of the foundation surface after excavation, geological sketch and excavation acceptance, bolt construction, foundation cleaning, steel bar installation and formwork assembly, Foundation cleared and concrete poured. The whole treatment process needs to c...

AI Technical Summary

Problems solved by technology

The whole treatment process needs to clean the foundation surface 3 times. As the construction progresses, the difficulty of cleaning becomes more and more difficult each time. The whole construction process requires a lot of manpower, which is time-consuming and laborious, and the quality is difficult to guarantee, which is not good for the foundation of the project.
