Embodiment 1

[0062] Embodiment 1, a filling method, using a gob-side entry retaining horizontally inclined double-stretched fiber flexible formwork, such as Figure 6 As shown, it is specifically implemented in the following ways and steps;

[0063] Step 1. According to the size of the position that needs to be filled between the roadway roof and the roadway floor in the gob-side entry retention, use wooden point columns 14 on the side of the goaf to block gangue support, and use single hydraulic props 15 on the side of the gob-side entry retention roadway Hanging nets to block gangue support;

[0064] Step 2. According to the length of filling, place several flexible formworks of gob-side entry retaining with double-stretched fibers;

[0065] Step 3. According to the size of the filling height, select the sleeve 11 on the top transverse flange 3 of the main body formwork 1, and penetrate the steel bars, and at the same time wear the steel bars on the transverse flange 3 in the middle of ...

Embodiment 2

[0073] Embodiment 2, a filling method, using a gob-side entry retaining horizontally inclined double-stretched fiber flexible formwork, such as Figure 7 As shown, it is specifically implemented in the following ways and steps;

[0074] Step 1. According to the size of the position that needs to be filled between the roadway roof and the roadway floor in the gob-side entry retention, use the gangue-blocking hanging formwork support 13 on the side of the goaf to block gangue support, and use the single hydraulic pressure on the side of the gob-side entry retention roadway. Pillar 15 hangs the net and carries out gangue retaining support;

[0075] Step 2. According to the length of filling, place several flexible formworks of gob-side entry retaining with double-stretched fibers;

[0076] Step 3. According to the size of the filling height, select the sleeve 11 on the top transverse flange 3 of the main body formwork 1, and penetrate the steel bars, and at the same time wear th...

Abstract

The invention discloses a gob-side-entry-retaining transverse-slant-dual-pulling fiber flexible template. The fiber flexible template comprises a template body. A top connecting template body is connected to the template body. The template body is provided with filling openings, anchor bolt holes, transverse flanges and vertical flanges. Sleeves are connected to the transverse flanges. Bar embedding holes are formed in the top connecting template. A plurality of transverse tying bars and a plurality of slant tying bars are arranged in the template body. The two ends of the transverse tying bars are fixed to the two opposite faces inside the template body through bar arranging rings respectively. The two ends of the slant tying bars are slantly fixed to the two connected faces on the inner side of the template body through bar arranging rings respectively. Reserved holes are further formed in the template body and are of cylindrical structures made of flexible template cloth in advance. By means of the template, lateral deformation generated after filling of the flexible template can be limited, the flexible template is evenly stressed during filling accordingly, and a filling body is high in strength and crack resistance accordingly. The invention further discloses a method for carrying out flexible template concrete construction through the gob-side-entry-retaining transverse-slant-dual-pulling fiber flexible template. According to the method, a pipe is convenient to install, and the construction speed is high.

Description

technical field [0001] The invention belongs to the technical field of coal mining support in coal mines, and relates to a gob-side entry retaining horizontally oblique double-drawn fiber flexible formwork, and also relates to a filling method using gob-side entry retaining transversely inclined double-drawn fiber flexible formwork. Background technique [0002] Application number: 200910023718.1, announcement number: 101649744, announcement date: 2011.12.28, the title of the invention is "device and method for pouring concrete continuous wall along gob-side entry in mining face", which involves fiber flexible formwork and its construction method, but the During the use of the template, the lateral and longitudinal deformation of the template is relatively large, and even broken. At the same time, in high-gas mines, mines prone to spontaneous combustion of coal seams, and mines with rich water in surrounding rocks, it is necessary to construct such as gas drainage pipes, nit...
