Abstract
The utility model relates to a large-framework concrete gob-side separation wall, which is formed by supporting bodies and a cementing material filled between the supporting bodies. The material of each supporting body is one or more of a building block, a steel pipe, a concrete framework or a gangue. The large-framework concrete gob-side separation wall has a simple structure and is convenient to use. A plurality of gob-side separation walls which can be adapted to complicated underground conditions of a coal mine can be derived. A large-framework pre-stress steel pipe concrete structure separation wall and a large-framework pre-stress framework concrete separation wall are separation walls which have primary supporting forces and are adapted to large-inclined-angle coal layers. The separation wall has the advantages of fast construction speed, high labor efficiency and good construction effect, and can be widely applied to industries of the coal mine, a metallurgical mine, a water conservancy project, an underground building, national defense and the like.
Description
Technical field
The utility model belongs to the colliery construction field, is specifically related to a kind of big skeleton concrete along empty divider wall.
Background technology
Some gob side entry retainings of face adopt high water filling material divider wall or concrete continuous wall, though the application of such divider wall technology is a lot, have the hypodynamic shortcoming of the slow and early stage support of setting rate, cause the influence to safety in production easily.
The utility model content
The purpose of the utility model is the deficiency that is to prior art, provides a kind of simple in structure, and cost is low, and efficiency of construction is high, has setting load and is adapted to large-inclination-angle coal bed big skeleton concrete along empty divider wall.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is: a kind of big skeleton concrete is characterized in that by supporter along empty divider wall, and the cementitious materials of between supporter, filling is formed.
Said support body material is one or more in building block, steel pipe, concrete frame or the spoil.
Said supporter is that the column shape of monomer column or multiple concrete block masonry is arranged.
Said supporter is the body of wall that is arranged on along goaf side.
Said supporter is the column that is arranged on along four jiaos of empty divider walls.
Said column stage casing is provided with the prestressing force unit.
Said cementitious materials is the filler that hydraulic material or organic-inorganic reaction generate.
The utility model compared with prior art has the following advantages:
Big skeleton concrete has high strength roof supporting in time along empty divider wall, prevents the inbreak of top board nexine, does not influence the work plane ordinary production, can practice thrift support material, and working security is high.

The specific embodiment
Embodiment one:
A kind of big skeleton concrete is along empty divider wall, forms the column frame of multiple lines and multiple rows by building block 2, and the skeleton slit of building block 2 being formed with the filling cementitious matter 1 of hydraulic material is filled and completely constituted complete body of wall.
Filling cementitious matter 1 is a hydraulic material.
Embodiment two:
A kind of big skeleton concrete is made up of along the knee wall of the body of wall both sides of empty divider wall building block 2 along empty divider wall, with the filling cementitious matter 1 of hydraulic material slit between the knee wall of building block 2 compositions is filled completely to constitute big skeleton concrete along empty divider wall.
The filler that filling cementitious matter 1 generates for the organic-inorganic reaction.
Embodiment three:
A kind of big skeleton concrete is along empty divider wall, is made up of along the support column of four jiaos of the bodies of wall of empty divider wall building block 2, and the slit is filled and completely constituted big skeleton concrete along empty divider wall between the support column of building block 2 being formed with the filling cementitious matter 1 of hydraulic material.
Embodiment four:
A kind of big skeleton concrete is along empty divider wall; Form along the support column of four jiaos of empty divider walls by vertical support unit 3; 3 centres, vertical support unit are provided with prestressing force unit 4 up and down, with the filling cementitious matter 1 of hydraulic material slit between the support column are filled completely to constitute big skeleton concrete along empty divider wall.
Embodiment five:
A kind of big skeleton concrete is along empty divider wall; Form along the peripheral support column of empty divider wall by supporting member 5; Empty divider wall centre, edge is provided with spoil 6, with the filling cementitious matter 1 of hydraulic material slit between the support column is filled completely to constitute big skeleton concrete along empty divider wall.
Big skeleton concrete has high strength along empty divider wall, and in time roof supporting prevents the inbreak of top board nexine, does not influence the work plane ordinary production, can practice thrift support material, and working security is high.
