Description

Active radial closed partition wall

Technical Field

The utility model relates to a coal mining field, concretely relates to initiative radial seal division wall.

Background

In the coal mining process, some roadways are required to be sealed and isolated according to different periods of use, and the sealing requirement is that the roadways have sealing performance and certain strength. Existing containment isolations are subject to requirements relating to industry specifications or government regulatory agencies. Mainly adopts a structure that loess filler is added in the middle of two building blocks to build the isolation wall. The isolation wall has the following serious problems that a large number of joints exist in building by building blocks, cracks inevitably exist when the building body and a roadway roof cannot be exactly and properly abutted, and loess filling has gravity settlement, and particularly generates a large amount of settlement in a collapsibility when meeting moisture and water. The two masonry walls of the partition wall have the possibility of seam air permeability, untight sealing of the top plate and loess collapsible settlement. The construction needs more people and long period, and sometimes the engineering requirements are difficult to meet.

The concrete isolation wall appearing in recent years overcomes the problems of a large number of masonry joints and loess collapsibility of the traditional isolation wall, and also improves the strength. However, the sealing problem is not solved, so that the original roadway supporting structure needs to be removed at the wall side and the top plate notch during construction to increase the contact tightness and the area, and the problem of untight top sealing is still not solved well.

The masonry wall filling method based on the loess filling technology solves the technical problems that a large number of masonry joints are breathable and the top of the whole isolation wall cannot be tightly connected, and the existing construction problem is that a large number of people are needed and the construction period is long. In recent years, the improved partition wall only improves the construction process, still does not overcome the sealing problem of the top plate of the wall of the roadway, and also has the problem that the structural requirement of the specification requirement of adding loess filling materials between two partition walls cannot be met.
