Abstract
The invention discloses a mould bag grouting device which comprises a mould bag (1), an outer pipe (2), a mould bag grouting pipe (3) and rock body grouting pipes (4). The rock body grouting pipes (4) penetrate through the outer pipe (2), the two ends of the outer pipe (2) are welded to the corresponding rock body grouting pipes (4), gaps are formed between the rock body grouting pipes (4) and the outer pipe (2), the outer pipe (2) is inserted in the mould bag (1) from the upper end of the mould bag (1), the rock body grouting pipes (4) penetrate through the mould bag (1), one end of the mould bag (1) is arranged at the upper end of the outer pipe (2) in a sleeving mode, the other end of the mould bag (1) is arranged at the lower end of the outer pipe (2) in a sleeving mode, the upper end of the outer pipe (2) is provided with the mould bag grouting pipe (3) communicated with the gaps, a cylindrical face of the outer pipe (2) is further provided with a plurality of through holes (7), and the through holes (7) are communicated with the gaps and an inner cavity of the mould bag (1). The mould bag grouting device has the advantages of being compact in structure, easy to operate and good in water plugging effect, and the mould bag can be arranged downwards easily.
Description
Technical field
The present invention relates to the technical field of water burst and 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 adopting conventional cement slurries to inject, cement paste can run off with entering lower current, effectively can not form cement slurry, the effect of water blockoff can not be realized, traditional grout pipe grouting way: adopt geotextiles to be processed into bag-shaped, preset Grouting Pipe again, Grouting Pipe and grout pipe colligation firmly make it to expand to slip casting in bag by presetting Grouting Pipe afterwards, to reach the object of sealing or fixing grout pipe, be in the milk by grouting orifice pipe again, to reach the object in crack on shutoff rock mass, but, this grout pipe grouting way is except mould bag colligation making is loaded down with trivial details, also there is mould bag, to take grout hole space large, underlying difficulty, and mould bag is fragile comes off, success rate is low.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, a kind of compact conformation be provided, simple to operate, underlying mould bag is easy, mould bag grouting device that water plugging effect is good.
Object of the present invention is achieved through the following technical solutions: a kind of mould bag grouting device, it comprises 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, 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 upper end of described outer tube is provided with the mould bag Grouting Pipe of connectivity gap, the cylinder of outer tube is also provided with the through hole of multiple connectivity gap and mould bag inner chamber.
Described through hole is evenly distributed on outer tube.
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 present invention has the following advantages: (1) the present invention can pass into cement paste through mould bag Grouting Pipe in space, cement paste via through holes enters in mould bag, the cement grout injected is due to the constraint of mould bag, a cement grout difficulty stays in mould bag, can not flow, and form cement calculus slurry with current, under the effect of grouting pressure, cement Seed harvest and hole wall close contact, thus blocking water stream channel, achieve quick water blockoff and water plugging effect is good.(2) low cost of manufacture of the present invention, simple to operate, and rock mass grout pipe does not take the space of mould bag, and therefore, underlying mould bag is more prone to convenient.
Accompanying drawing explanation
Fig. 1 is 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
Below in conjunction with accompanying drawing, the present invention will be further described, 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 comprises 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, two ends of outer tube 2 are welded between rock mass grout pipe 4 and outer tube 2 with corresponding rock mass grout pipe 4 and are formed space, 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, 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 upper end of described outer tube 2 is provided with the mould bag Grouting Pipe 3 of connectivity gap, the cylinder of outer tube 2 is also provided with the through hole 7 of multiple connectivity gap and mould bag 1 inner chamber, through hole 7 is evenly distributed on outer tube 2.
As shown in Figure 1, an 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 course of work of the present invention is as follows: first extend in the hole with water burst by mould bag 1 and outer tube 2, and make the outer wall of mould bag 1 near water burst position, in space, pass into cement paste through mould bag Grouting Pipe 3 again, cement paste via through holes 7 enters in mould bag 1, and the cement grout of injection is due to the constraint of mould bag 1, a 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 and hole wall close contact, and block water stream channel.Thus realize water blockoff.
The above is only the preferred embodiment of the present invention, be to be understood that the present invention is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from the spirit and scope of the present invention, then all should in the protection domain of claims of the present invention.
