Abstract
The invention relates to a preliminary supporting bag cast isolation wall and a placing method thereof. The preliminary supporting bag cast isolation wall consists of struts, flexible membrane bags and cement solidifying materials, the struts are disposed on the outer layer of the preliminary supporting bag cast isolation wall, the flexible membrane bags are fixed on the struts, and the cement solidifying materials are arranged in the flexible membrane bags. The struts are single columns or concrete upright columns or mining anchor columns with upright column supporting performances. During implementation, the struts are punched at designed positions of a top plate and a bottom plate at the rear of a back production support of a coal face at first, and the top plate and the bottom plate are anchored together to realize dual effects including an anchoring effect and a supporting effect. The flexible membrane bags are fixed by the aid of the struts or anchor bolts and anchor cables of the top plate, and the cement solidifying materials are poured in the membrane bags. The isolation wall and the placing method are applicable to quick gob-side entry retaining construction. The invention is particularly suitable for gob-side entry retaining isolation walls of steep seams. More importantly, the shortcoming that an isolation wall in the prior art does not have timing supporting ability is overcome, and the problem that the top plate is unsupported or the top plate is damaged artificially due to the fact that the top plate is supported repeatedly is avoided. Construction speed is fast, efficiency is high, and a construction effect is good.
Description
Technical field
The invention belongs to coal mining engineering field, be specifically related to a kind of preparatory support pouches casting divider wall and placing method thereof.
Background technology
Traditional mining activity face gob-side entry retaining adopts grillage, close standing props, spoil bag, work stone is built a wall or concrete continuous wall as roof supporting.Grillage, close standing props supporting intensity hang down and can not satisfy most of requirement of engineering.Spoil bag, work stone are built a wall can not connect to push up and are caused the excessive sinking of top board to make supporting effect not good.Though high water filling material and gentle mould concrete have solved divider wall and have in time connect the top problem.But can not solve body of wall and in time top board applied support force.Do not cause roof collapse can have a strong impact on production and safety in some cases easily and pay support timely in advance.If adopt traditional hydraulic prop high and have the pressure release situation and take place as the supporting member cost.And the gob side entry retaining divider wall will can be good at adapting to the supporting member that efficient stoping operation just must have certain setting load.
Summary of the invention
The objective of the invention is to be the deficiency to prior art, a kind of safety in production is provided, and supporting effect is good, has the preparatory support pouches casting divider wall and the placing method thereof of timely enabling capabilities.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:
A kind of preparatory support pouches casting divider wall is characterized in that by being arranged on outer field pillar, being fixed in flexible membrane bag and the flexible membrane bag on the pillar glued curing materials and forming.
Support pouches is cast the placing method of divider wall in advance, may further comprise the steps:
1) at first at the peripheral mounting column of design isolated wall;
2) the flexible membrane bag is fixed on when pillar is installed on the top board simultaneously or install pillar after be fixed on the pillar;
3), solidify the back and form preparatory support pouches casting divider wall through fill orifice concreting in bag of flexible membrane bag
Said pillar is that monomer column or concrete column or mining anchor post with upright supports performance are processed.
Support pouches is cast the placing method of divider wall in advance, may further comprise the steps:
1) sets anchor pole or anchor cable at the roof and floor design attitude;
2) anchor pole that sets at roof and floor or anchor cable position are provided with pillar and are connected with ground crab-bolt or anchor cable;
3) apply support force to pillar, accomplish pillar and install;
4) the flexible membrane bag is fixed on when pillar is installed on the top board simultaneously or install pillar after be fixed on the pillar;
5), solidify the back and form preparatory support pouches casting divider wall through the glued curing materials of fill orifice placing in bag of flexible membrane bag.
The present invention compared with prior art has the following advantages:
1) the placing method of support pouches casting divider wall is simple, easy to use in advance.
2) with the present invention top board and base plate are anchored at and form anchoring together and support double action.
3) be adapted to the divider wall that sharp gob side entry retaining is constructed, be particularly suitable for the gob side entry retaining divider wall of half-edge coal seam.

The specific embodiment
Like Fig. 1, a kind of preparatory support pouches casting divider wall shown in 2, it is characterized in that forming by the flexible membrane bag 11 and the flexible membrane bag inner concrete 13 that are arranged on outer field pillar 12, be fixed on the pillar 12.
Support pouches is cast the placing method of divider wall in advance, may further comprise the steps:
1) at first at the peripheral mounting column 12 of design isolated wall;
2) when pillar 12 is installed, be fixed on the top board simultaneously flexible membrane bag 11 or install pillar 12 after be fixed on the pillar 12;
3), solidify the back and form preparatory support pouches casting divider wall through fill orifice concreting 13 in bag of flexible membrane bag 11.
As shown in Figure 3, pillar 12 is by outer field outer piston 3, and inner carrier 2 two parts that are arranged in the outer piston 3 constitute; Inner carrier 2 upper ends are provided with the top end cover 1 that is used to lock the top crab-bolt; Outer piston 3 lower ends are provided with the bottom cover 5 that is used to connect the ground crab-bolt; Outer piston 3 is provided with the tight locking button 6 that is used to prevent the inner carrier downslide with inner carrier 2 contact portions, and outer piston 3 lower ends are provided with injected hole 4.
Said outer piston 3 internal layers are filled with glued curing materials 7.
Support pouches is cast the placing method of divider wall in advance, may further comprise the steps:
6) set anchor pole 9 or anchor cable at the roof and floor design attitude;
7) bottom cover 5 of pillar 12 is connected with ground crab-bolt or anchor cable;
8) utilize grouting equipment to pass through the inner carrier 2 that grouting port 4 reperfusion serosities rise pillar 12;
9) top end cover 1 was connected with top crab-bolt 9 or anchor cable after inner carrier 2 rose;
