Abstract
nullThe invention discloses a kind of mould bag grouting device，It includes mould bag (1)、Outer tube (2)、Mould bag Grouting Pipe (3)、Rock mass grout pipe (4)，Rock mass grout pipe (4) runs through outer tube (2) and arranges，Two ends of outer tube (2) are welded with corresponding rock mass grout pipe (4)，Space is formed between rock mass grout pipe (4) and outer tube (2)，Outer tube (2) is inserted in mould bag (1) from the upper end of mould bag (1)，Rock mass grout pipe (4) runs through mould bag (1) and arranges，The one end of mould bag (1) is enclosed within the upper end of outer tube (2)，The other end of mould bag (1) is enclosed within the bottom of outer tube (2)，Mould bag Grouting Pipe (3) of connectivity gap it is provided with on the upper end of outer tube (2)，The through hole (7) of multiple connectivity gap and mould bag (1) inner chamber it is additionally provided with on the cylinder of outer tube (2).The invention has the beneficial effects as follows: compact conformation, mould bag simple to operate, underlying is easy, water plugging effect good.
Description
Technical field
The present invention relates to retention of excessive fluid and the technical field of Rockmass fractures in plugging hole, particularly a kind of mould bag grouting device.
Background technology
At present, in the rock mass that groundwater velocity is higher, when using conventional cement slurries to inject, cement mortar can run off with entering lower current, cement slurry can not be effectively formed, the effect of water blockoff can not be realized, traditional grout pipe grouting way: use geotextiles to be processed into bag-shaped, preset Grouting Pipe again, after Grouting Pipe and grout pipe colligation firmly by default Grouting Pipe in bag slip casting and be allowed to expand, to reach sealing or the purpose of fixing grout pipe, it is in the milk by grouting orifice pipe again, to reach to block the purpose in crack on rock mass, but, this grout pipe grouting way is in addition to mould bag colligation making is loaded down with trivial details, there is also mould bag, to take grout hole space big, underlying difficulty, and mould bag is fragile comes off, success rate is low.
Summary of the invention
It is an object of the invention to overcome the shortcoming of prior art, it is provided that a kind of compact conformation, the mould bag grouting device that simple to operate, underlying mould bag is easy, water plugging effect is good.
The purpose of the present invention is achieved through the following technical solutions: a kind of mould bag grouting device, it includes mould bag, outer tube, mould bag Grouting Pipe, rock mass grout pipe, described rock mass grout pipe runs through outer tube and arranges, two ends of outer tube are welded with corresponding rock mass grout pipe, space is formed between rock mass grout pipe and outer tube, described outer tube is inserted in mould bag from the upper end of mould bag, rock mass grout pipe runs through mould bag and arranges, the one end of described mould bag is enclosed within the upper end of outer tube, the other end of mould bag is enclosed within the bottom of outer tube, the mould bag Grouting Pipe of connectivity gap it is provided with on the upper end of described outer tube, multiple connectivity gap and the through hole of mould bag inner chamber it is additionally provided with on the cylinder of outer tube.
Described through hole is evenly distributed on outer tube.
The one end of described mould bag is stuck on outer tube through termination pipe clamp A.
The other end of described mould bag is stuck on outer tube through termination pipe clamp B.
The invention have the advantages that (1) present invention can be passed through cement mortar through mould bag Grouting Pipe in space, cement mortar via through holes enters in mould bag, the cement grout injected is due to the constraint of mould bag, cement grout difficulty stays in mould bag, it is impossible to flow with current, and forms cement calculus slurry, under the effect of grouting pressure, cement Seed harvest is in close contact with hole wall, thus blocks water stream channel, it is achieved that quickly water blockoff and water plugging effect are good.(2) low cost of manufacture of the present invention, simple to operate, and rock mass grout pipe is not take up the space of mould bag, and therefore, underlying mould bag is more prone to convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
In figure, 1-mould bag, 2-outer tube, 3-mould bag Grouting Pipe, 4-rock mass grout pipe, 5-termination pipe clamp A, 6-termination pipe clamp B, 7-through hole.
Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings, and protection scope of the present invention is not limited to the following stated:
As shown in Figure 1, a kind of mould bag grouting device, it includes mould bag 1, outer tube 2, mould bag Grouting Pipe 3, rock mass grout pipe 4, described rock mass grout pipe 4 runs through outer tube 2 and arranges, formation space between rock mass grout pipe 4 and outer tube 2 is welded in two ends of outer tube 2 with corresponding rock mass grout pipe 4, described outer tube 2 is inserted in mould bag 1 from the upper end of mould bag 1, rock mass grout pipe 4 runs through mould bag 1 and arranges, the one end of described mould bag 1 is enclosed within the upper end of outer tube 2, the other end of mould bag 1 is enclosed within the bottom of outer tube 2, the mould bag Grouting Pipe 3 of connectivity gap it is provided with on the upper end of described outer tube 2, multiple connectivity gap and the through hole 7 of mould bag 1 inner chamber it is additionally provided with on the cylinder of outer tube 2, through hole 7 is evenly distributed on outer tube 2.
As it is shown in figure 1, the one end of mould bag 1 is stuck on outer tube 2 through termination pipe clamp A5；The other end of described mould bag 1 is stuck on outer tube 2 through termination pipe clamp B6.
The work process of the present invention is as follows: first mould bag 1 and outer tube 2 are extend in the hole with retention of excessive fluid, and make the outer wall of mould bag 1 near water burst position, being passed through cement mortar in space through mould bag Grouting Pipe 3 again, cement mortar via through holes 7 enters in mould bag 1, and the cement grout of injection is due to the constraint of mould bag 1, cement grout difficulty stays in mould bag, can not flow with current, and form cement calculus slurry, under the effect of grouting pressure, cement Seed harvest is in close contact with hole wall, and blocks water stream channel.Thus realize water blockoff.
The above is only the preferred embodiment of the present invention, it is to be understood that the present invention is not limited to form disclosed herein, it is not to be taken as the eliminating to other embodiments, and can be used for other combinations various, amendment and environment, and can be modified by above-mentioned teaching or the technology of association area or knowledge in contemplated scope described herein.And the change that those skilled in the art are carried out and change are without departing from the spirit and scope of the present invention, the most all should be in the protection domain of claims of the present invention.
