Miniature pile and anchor cable combined supporting structure for treating dangerous rock mass and construction method of miniature pile and anchor cable combined supporting structure

Abstract

The invention discloses a miniature pile and anchor cable combined supporting structure for treating dangerous rock mass and a construction method of the miniature pile and anchor cable combined supporting structure. The structure comprises miniature steel pipe piles arranged in double rows, wherein pile top crown beams are arranged at the tops of the miniature steel pipe piles, and the pile top crown beams connect the double rows of piles to enable the double rows of piles to be integrally and synergistically stressed; prefabricated concrete baffles are arranged between the miniature steel pipe piles, meanwhile, PVC drainage pipes are arranged between the miniature steel pipe piles to drain out crack water of the dangerous rock mass, and gaps between the miniature steel pipe piles and thedangerous rock mass are backfilled with concrete, so that the dangerous rock mass at the lower portion makes full contact with the ground; and the dangerous rock mass at the upper portion is supported by matching lattice beams with pre-stressed anchor cables, covering soil is arranged in gaps between the lattice beams for backfilling, and grass seeds are planted in the covering soil for greeningdesign. According to the miniature pile and anchor cable combined supporting structure for treating dangerous rock mass and the construction method of the miniature pile and anchor cable combined supporting structure, due to the fact that the miniature piles are high in construction speed, development of dangerous rock mass deformation can be preliminarily controlled in a short time, and high efficiency is achieved.

Description

technical field [0001] The invention relates to a treatment method for a dangerous rock mass that may develop into a landslide, in particular to a combined support structure of micro piles and anchor cables for treating dangerous rock mass and a construction method thereof. Background technique [0002] Dangerous rock masses are mostly located on steep slopes or cliffs and are cut by multiple groups of structural planes. Although they have not yet experienced instability, they have already met the conditions for instability and failure. Under gravity, weathering force, earthquake, seepage pressure and external environment Under the action of external forces such as vibration interference, it may lead to instability and failure of separation from the parent rock, resulting in casualties or property losses below, which is a typical geological disaster. The methods related to the management of dangerous rock mass in the prior art generally have the following several types: [...
