Embodiment Construction

[0015] Such as figure 1 As shown, an adjustable annular double-layer airbag sealing device includes:

[0016] Main pipeline: metal material or non-metal material, used to connect grouting, drainage and air extraction pipelines after sealing. When the pipeline exceeds 6m, it can be divided into two sections, and when the pipeline exceeds 9m, it can be divided into three sections, and the middle is connected by internal and external wires (screws), with an outer diameter of 50-100mm. In order to increase the friction between the pipe and the annular airbag, use a lathe to process a 40-70 mm long thread at the place where the annular airbag is installed. The place where the annular airbag is installed is generally 1-3m away from both ends of the pipe. depending on the position of the hole section);

[0017] The first annular double-layer airbag and the second annular double-layer airbag: the annular airbag is made of rubber material, the length is 20-50cm, the inner diameter i...

Abstract

The invention belongs to a hole sealing apparatus in processes of grouting, water plugging, gas extraction and the like and particularly relates to an adjustable annular double-layer air bag hole sealing device and a method for performing hole sealing. The adjustable annular double-layer air bag hole sealing device comprises a main pipeline, a first annular double-layer air bag, a second annular double-layer air bag, a first admission pipe, a second admission pipe and a grouting pipe, wherein the upper end of the main pipeline is fixedly provided with the first annular double-layer air bag; the lower end of the main pipeline is fixedly provided with the second annular double-layer air bag; the first annular double-layer air bag is connected with the first admission pipe through a first air inlet; the second annular double-layer air bag is connected with the second admission pipe through a second air inlet; a preformed hole in the first annular double-layer air bag is connected with the middle position of the first annular double-layer air bag and the middle position of the second annular double-layer air bag; the grouting pipe is inserted into the preformed hole.

Description

Technical field [0001] The present invention is a sealing equipment in the process of grouting, blocking water, and gas pumping. It specially involves a method of adjustable ring -shaped gas double -layer pockets and the method of sealing holes. Background technique [0002] In the process of grouting, water blocking, and gas pumping involved in construction or mining construction, sealing is the key link in construction. The sealing effect greatly affects the quality of construction and even determines its success or failure. [0003] The existing drilling fluxing technology is mainly blocked by grouting, polyurethane, etc., and commonly used in the pocket pocket grouting and blocking, airbag grouting and blocking.For a long time, it cannot achieve fast sealing holes. In the case of water, gas and other mediums, it is impossible to achieve effective blocking defects when it is sprayed from the holes.The defects of the method, but there are problems with many assembly components ...
