Abstract
The utility model discloses a mould bag for concreting a gob-side entry retaining partition wall. The mould bag is an enclosed bag. The mould bag structurally comprises a fixing ear drum, a perfusion air vent, a mould bag top, a reinforcing rib, a connecting feather eave, an anchoring hole and a grouting pore path, wherein the fixing ear drum is a cylindrical structure. With the adoption of the structure, the mold bag is convenient to manufacture and can be the quickly fixed. The mould bag is applicable to the concreting of the gob-side entry retaining partition wall, has simple structure and fast construction speed, and is widely applied to civil engineering industries such as coal mine, building, metallurgy mine, water conservancy, underground building and national defense and the like.
Description
Technical field
The utility model relates to the mould bag that a kind of concreting uses, and is specifically related to the mould bag that a kind of gob side entry retaining partition wall concreting uses.
Background technology
Rigid template is used in concreting always.Sometimes there is serious spillage in rigid template.Especially when the isolation body of wall of building by laying bricks or stones between roof and floor, can not be implemented in the pouring of template top.If adopt the pumping liquid concrete technology in rigid template, the seam spillage of template can influence the concrete filling compaction rate.So just had such as the device of application (patent) number 200920034356.1 mining activity face gob-side entry retaining casting concrete continuous walls and the such patent of flexible filling bag of application (patent) number 200720046802.1 1 kinds of carrying pipes.These all are to the utility model after the improvement of rigid template defective.But existing this class filling bag comes with some shortcomings in construction.The not enough simplicity of mould bag manufacture craft for example, mould bag connection reliability is not good, and the mould bag sets up and has defective etc.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, especially builds the convenient and swift of divider wall by laying bricks or stones in order to adapt to coal mine gob-side entry retaining, provides a kind of simple in structure, and speed of application is fast, the mould bag that the gob side entry retaining partition wall concreting of reliable in structure uses.
In order to realize above-mentioned task, the technical solution adopted in the utility model is:
The mould bag that a kind of gob side entry retaining partition wall concreting uses is characterized in that this mould bag is an enclosed construction, includes fixedly ear tube, perfusion steam vent, mould bag top, ribs, connection plumage eaves, dowel hole and grouting duct on the described mould bag constructions.
Described fixedly ear tube is a tubular structure.Its tubular diameter is 10-150mm, and length is identical with mould bag top margin.
Described perfusion steam vent diameter is 10-150mm.
Make for a slice soft cloth on described mould bag top.
Described connection plumage eaves is a bar shaped cloth sheet or tubular construction, has a plurality of connecting holes on it, and the diameter of connecting hole is 10-20mm, and the connecting hole spacing is 50-200mm.
Described dowel hole and grouting duct are one and connect the inside and outside tubular soft cloth of mould bag.Length in the mould bag is greater than 2 times channel diameter.
Described grouting duct is positioned at the first half of mould bag more than 1/5th.
Described ribs is evenly distributed on mould bag both sides.
Of the present utility modelly compared with prior art have the following advantages:
Tubular fixedly ear barrel structure bag is convenient, and can reach fixing fast, and the edge of mould bag can be good at connecing the top, can guarantee that concrete seals between roof and floor.Soft roof construction is convenient to pumping liquid concrete and is connect the top.Have a plurality of connecting holes on the connection plumage eaves and be very beneficial for closely linking fast between two mould bags.The grouting pore passage structure of tubular can realize that self sealss prevent spillage.Adopt the utility model speed of application fast, the efficiency height.This mould bag can be widely used in the colliery, building, metallurgical mine, water conservancy, underground building, civil engineering industries such as national defence.
Description of drawings
Fig. 1 is a gob-side entry retaining concrete partition wall construction mold bag constructions schematic diagram of the present utility model.
Fig. 2 is for adopting the utility model gob-side entry retaining concrete partition wall construction mold bag construction embodiment schematic diagram.
Number in the figure is represented respectively: 1, fixing ear tube, 2, the perfusion steam vent, 3, mould bag top, 4, ribs, 5, first connects the plumage eaves, and 6, the dowel hole, 7, the grouting duct, 8, individual prop, 9, rigid bar, 10, second connects the plumage eaves, and 11, roof, 12, seat earth.
The specific embodiment
Referring to Fig. 1,, make a gob-side entry retaining concrete partition wall construction mold bag according to the physical dimension of gob side entry retaining divider wall, this mould bag constructions is by fixing ear tube 1, slip casting steam vent 2, flexible fiber top 3, ribs 4 connects plumage eaves 5, and dowel hole 6 and grouting duct 7 are formed.
Gu top ear tube diameter is 30mm; Perfusion steam vent 2 diameters are 10-150mm.
Slip casting steam vent orifice throat length is 120mm;
Make for knitting cloth on flexible fiber 3 tops;
Connect plumage eaves 5 and do not make a call to the connecting hole of a diameter phi 15 every 50mm for not sewing up the tubular construction that forms, connecting on the plumage eaves 5 with giving a discount.
Dowel hole 6 and grouting duct 7 are one and run through the inside and outside tubular soft cloth structure of mould bag that grouting duct 7 is made for the tubular cloth of diameter phi 150;
Described grouting duct 7 is positioned at the first half of mould bag more than 1/5th.
Ribs 4 is evenly distributed on mould bag both sides.
It is as follows to adopt above-mentioned gob-side entry retaining concrete partition wall construction mold bag to carry out construction sequence:
1, the gob-side entry retaining concrete partition wall construction mold bag is placed on the seat earth 12, rope is pierced into first connecting hole that connects plumage eaves 5 the mould bag is connected plumage eaves 10 with second of adjacent mould bag is fixed together;
2, rigidity back timber 9 is penetrated fixedly ear tube 1;
3, rigidly fix back timber 9 until to roof 11 with what individual prop 8 jackings were positioned at fixing ear tube 1;
4, elephant trunk is connected with grouting duct 7, in the mould bag, injects a small amount of concrete from grouting duct 7;
