Rock pipe-jacking water grinding drill and drilling method

Abstract

The invention provides a rock pipe-jacking water grinding drill and a drilling method. The rock pipe-jacking water grinding drill comprises a supporting frame, a rotating arm, an adjusting device anda water grinding drill; a rotating frame of the rotating arm is matched with a shaft body of the supporting frame; the adjusting device is connected with the supporting frame and the rotating arm; thewater grinding drill is in sliding fit with the rotating frame of the rotating arm; a cross rod and a vertical rod are fixed to the internal wall of a rock cave; the adjusting device adjusts the angle of the rotating frame; the water grinding drill drills holes; the holes are connected with each other to form a circular ring; and drilling and tunneling are carried out in the circular ring in an impact manner. According to the rock pipe-jacking water grinding drill, the problems of low construction efficiency, high cost and complicated operation in the original rock pipe-jacking process are solved; and the rock pipe-jacking water grinding drill has the characteristics of simple structure, stable rock cave tunneling, high drilling efficiency, low cost and simple and convenient operation.

Description

technical field [0001] The invention belongs to the technical field of pipe jacking construction, and relates to a rock pipe jacking hydraulic drill and a drilling method. Background technique [0002] With the rapid development of urban construction, pipe jacking construction technology has been widely used in the laying of municipal pipelines, including electricity, heat, gas, water supply and drainage, communications, etc. [0003] At present, the commonly used methods in rock pipe jacking are: [0004] Pneumatic pick breaking method, blasting method, rock pipe jacking method, single water mill drilling method. [0005] The pickaxe crushing method is suitable for strongly weathered rocks, but it is almost impossible to crush moderately weathered rocks, and the construction progress is very slow; the construction of the blasting method is limited by the surrounding environment and underground pipelines, and blasting operations cannot be carried out in cities, and blasting...

AI Technical Summary

Problems solved by technology

[0005] The pickaxe crushing method is suitable for strongly weathered rocks, but it is almost impossible to crush moderately weathered rocks, and the construction progress is very slow; the construction of the blasting method is limited by the surrounding environment and underground pipelines, and blasting operations cannot be carried out in cities, and blasting procedures are difficult. The blasting method has an impact on the stability of the rock structure; the rock pipe jacking machine method for short-distance rock pipe jacking construction, the mechanical cost is very large, the construction cost is high, and the economy is unreasonable

The construction progress of the single water mill drilling method is relatively slow and the footage per cycle is 0.5m, which cannot meet the construction period requirements
