Gear type underground coal bunker walling crib and construction method of coal bunker provided with walling crib

Abstract

The invention discloses a gear type underground coal bunker walling crib and a construction method of a coal bunker provided with the walling crib, and belongs to the field of soft rock coal bunker support. The gear type underground coal bunker walling crib comprises a walling crib body (2) provided with at least one oblique face, and the walling crib body (2) is of a concrete reinforced structure. A plurality of anchor rods (4) are obliquely arranged in the walling crib body (2), and the anchor rods (4) are perpendicular to the oblique face of the walling crib body (2). Connecting bars (5) used for being connected with a coal bunker wall body (3) into a whole are arranged in the walling crib body (2). In the construction process, the coal bunker walling cribs are constructed on the outerportion of the coal bunker wall body circumferentially, the coal bunker walling cribs are hung in a soft rock layer, because a plurality of rounds of coal bunker walling cribs are arranged at intervals, it is ensured that the coal bunker wall cannot slide down, construction is simple and convenient, rapid, efficient and safe, and the cost is low. The gear type underground coal bunker walling cribhas obvious social benefits and economical benefits.

Description

technical field [0001] The invention relates to the field of soft rock coal bunker support, in particular to a gear type underground coal bunker wall seat and a construction method for the coal bunker wall with the wall seat. Background technique [0002] During the construction of the mine coal bunker, due to the passage through the thick coal seam, the lithology is relatively soft, and the coal bunker wall often slides down. In order to solve the problem of coal bunker wall sliding, the traditional construction method generally adopts the method of widening the bunker wall. That is, in the soft rock curtain to strengthen the support method, widen the support thickness. The process is complicated, especially in soft rock, the on-site construction is very difficult, and the cost is high and the workload is heavy. Contents of the invention [0003] In order to make up for the deficiencies of the existing technology and solve the problems of difficult construction, high co...
