Background technology
Mine Genesis of Karst Subsided Column be colliery common one structure, the crushed rocks that in karst collapse col umn, filling mechanical property is lower and argillaceous cave-sedimental fillings, normally permeable, support inbreak, gas accident, base plate are sunk accident, substantially all administer by the method for grouting and reinforcing in control at the scene, to ensure the safety of coal-face.The length of usual this area injected hole is at about 50m, what have even reaches about 100m, i.e. so-called deep hole, according to correlative study, when slip casting region away from Grouting Pipe more than 20m time, the pressure head of slip casting can sharply less, this is also the where the shoe pinches of Deep-hole Pre-grouting, common operation is used namely: punching-sealing of hole-slip casting-result inspection in mortar depositing construction process, in the injection hole sealing of karst collapse col umn reality, Grouting Pipe often sealing of hole is shorter and Grouting Pipe is shorter, there is the point lacked that face shows in this Grouting Pipe: 1, easily near Grouting Pipe aperture, there is hydraulic fracture, slurries are caused to waste serious and Coal Quality Decline, 2, slurries decline of pressure is in the borehole serious, and to when needing the region of grouting and reinforcing, grouting pressure can not ensure that slurries enter in karst collapse col umn, 3, slip casting tubing in the past uses steel pipe, and in follow-up mining, must leave the special time processes steel pipe, causes certain potential safety hazard, 4, after slip casting terminates, the whole tube wall of grout filling, causes the decline of concrete column difficult treatment and ature of coal in follow-up manufacturing process, reduces economic benefit, 5, can not realize the slip casting in specific aim place, often slip casting in a big way, slip casting efficiency is low.
Summary of the invention
The purpose of this utility model is: 1, hydraulic fracture does not occur near aperture, thus saves grout material and reduce ature of coal loss; 2, utilize the pvc pipe of flame-retardant and anti-static, steel pipe, as Grouting Pipe, can realize transmission that is easy for installation, that save tubing, realize high efficiency grouting pressure than ever mutually; 3, slip casting can realize utilizing coal-winning machine directly to cut through after terminating, and does not need to shut down to process specially, improves the efficiency of producing; 4, can realize the slip casting in specific aim place, improve slip casting efficiency, its technical scheme is as follows:
A kind of Grouting Pipe of reinforcing for karst collapse col umn Deep-hole Pre-grouting, it comprises main Grouting Pipe 1, auxiliary Grouting Pipe 2, stack 3, blowout prevention anchor pole 4, blowout prevention backplate 5, baffle ring 6, grout outlet 7, it is characterized in that: before described blowout prevention backplate 5, top end surface middle is fixedly fitted with main Grouting Pipe 1, described main Grouting Pipe 1 side top end surface is evenly distributed fixed cover and several baffle rings 6 is housed, on the left of the top end surface of described main Grouting Pipe 1 side, limit surrounding is evenly distributed and is provided with several grout outlets 7, be provided with auxiliary Grouting Pipe 2 above described main Grouting Pipe 1 and be fixedly inserted into blowout prevention backplate 5 front surface, be provided with stack 3 above described auxiliary Grouting Pipe 2 and be fixedly inserted into blowout prevention backplate 5 front surface, before described blowout prevention backplate 5, top end surface corner place is each is fixedly fitted with blowout prevention anchor pole 4, described main Grouting Pipe 1 is made up of PVC material, and described grout outlet about 7 distance on described main Grouting Pipe 1 side surface is 0.5m inside diameter is 40mm, described baffle ring 6 outer tip end surface is wound with encapsulant, described main Grouting Pipe 1 length is longer than auxiliary Grouting Pipe 2, described auxiliary Grouting Pipe 2 length is longer than stack 3, described main Grouting Pipe 1, auxiliary Grouting Pipe 2 and stack 3 are made up of PVC material.
The beneficial effects of the utility model are: 1, hydraulic fracture does not occur near aperture, thus save grout material and reduce ature of coal loss; 2, utilize the pvc pipe of flame-retardant and anti-static, steel pipe, as Grouting Pipe, can realize transmission that is easy for installation, that save tubing, realize high efficiency grouting pressure than ever mutually; 3, slip casting can realize utilizing coal-winning machine directly to cut through after terminating, and does not need to shut down to process specially, improves the efficiency of producing; 4, the slip casting in specific aim place can be realized, improve slip casting efficiency.
face said by accompanying drawing:
Fig. 1 is overall structure schematic diagram of the present utility model.
detailed description of the invention:
With reference to Grouting Pipe of reinforcing for karst collapse col umn Deep-hole Pre-grouting a kind of described in Fig. 1, it comprises main Grouting Pipe 1, auxiliary Grouting Pipe 2, stack 3, blowout prevention anchor pole 4, blowout prevention backplate 5, baffle ring 6, grout outlet 7, it is characterized in that: before described blowout prevention backplate 5, top end surface middle is fixedly fitted with main Grouting Pipe 1, described main Grouting Pipe 1 side top end surface is evenly distributed fixed cover and several baffle rings 6 is housed, on the left of the top end surface of described main Grouting Pipe 1 side, limit surrounding is evenly distributed and is provided with several grout outlets 7, be provided with auxiliary Grouting Pipe 2 above described main Grouting Pipe 1 and be fixedly inserted into blowout prevention backplate 5 front surface, be provided with stack 3 above described auxiliary Grouting Pipe 2 and be fixedly inserted into blowout prevention backplate 5 front surface, before described blowout prevention backplate 5, top end surface corner place is each is fixedly fitted with blowout prevention anchor pole 4, described main Grouting Pipe 1 is made up of PVC material, and described grout outlet about 7 distance on described main Grouting Pipe 1 side surface is 0.5m inside diameter is 40mm, described baffle ring 6 outer tip end surface is wound with encapsulant, described main Grouting Pipe 1 length is longer than auxiliary Grouting Pipe 2, described auxiliary Grouting Pipe 2 length is longer than stack 3, described main Grouting Pipe 1, auxiliary Grouting Pipe 2 and stack 3 are made up of PVC material.
