Grouting Pipe
Technical field
The present invention discloses a kind of Grouting Pipe, belongs to the technical field of building operations.
Background technology
In the building construction process, in the location that some is produced easily landslide or Soft Soil Layer when carrying out consolidation process, generally all can adopt Grouting Pipe that slurries are beaten in this corresponding location or the soil layer and reinforce.During construction, specifying the slip casting position to hole first, then Grouting Pipe is inserted into and carries out the slip casting operation in this hole.Along with improving constantly that building operations requires, the Grouting Pipe of existing structure more and more can not satisfy its requirement, and be mainly reflected in following 2 points: injection speed is slow, and the slurries diffusion is inhomogeneous.Simultaneously, because the Grouting Pipe length of existing structure all designs in advance, when therefore carrying out slip casting in some special locations, can run into the inadequate situation of Grouting Pipe length, will make troubles to construction like this, affect construction speed.
Summary of the invention
The purpose of this invention is to provide that a kind of injection speed is fast, slurries spread uniform Grouting Pipe.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of Grouting Pipe comprises the taper plug, connecting rod, the slip casting body that connect successively; Connecting rod one end is fixedly connected with the taper plug, the other end extends in the slip casting body from the mouth of pipe of slip casting body, and be positioned on the connecting rod end of slip casting body and be fixedly installed chuck, chuck activity holding is in the mouth of pipe, offer several through holes one on the chuck, and each through hole one is communicated with the mouth of pipe all; Offer several through holes two on the tube wall of slip casting body.Grouting Pipe of the present invention can solve the problem that injection speed is slow, the slurries diffusion is inhomogeneous, and is simultaneously simple in structure, easily manufactured.
As the further setting of such scheme, the end of described slip casting body is connected with the connection body with Demountable.The setting of the connection body of Demountable when needs increase the geologic province construction of Grouting Pipe length, can realize increasing the purpose of Grouting Pipe length, and convenient construction has been accelerated construction speed.
Described slip casting body is threaded connection with being connected between the body, and the slip casting body is provided with sealing ring with being connected between the body.
Be equipped with the rubber back-up ring on described slip casting body and the junction outer wall that is connected between the body.The setting of rubber back-up ring can further improve slip casting body and the sealing performance that is connected between the body, simultaneously further firmly slip casting body and the connection that is connected between the body.
Grouting Pipe of the present invention, owing on the front end mouth of pipe and tube wall of slip casting body, can carry out simultaneously pulp, realize that therefore injection speed is fast, slurries spread uniform purpose, effectively accelerate construction speed and improved construction quality, simultaneously simple in structure, easily manufactured.
The invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation (when arrow in figure the represent slip casting flow path of slurries) of the present invention when being in the slip casting state.
The specific embodiment
As shown in Figure 1, Grouting Pipe of the present invention comprises the taper plug 1, connecting rod 2, the slip casting body 3 that connect successively.Connecting rod 2 one ends are fixedly connected with taper plug 1, the other end extends in the slip casting body 3 from the mouth of pipe 31 of slip casting body 3, and be positioned on connecting rod 2 ends of slip casting body 3 and be fixedly installed chuck 5, chuck 5 activity holdings (are that chuck 5 activities are positioned at Grouting Pipe body 3 in the mouth of pipe 31, but can't break away from slip casting body 3 voluntarily by the mouth of pipe 31), offer several equally distributed through holes 1 on the chuck 5, and each through hole 1 is communicated with the mouth of pipe 31 all; Offer several equally distributed through holes 2 32 on the tube wall of slip casting body 3.
When the length of slip casting body 3 is inadequate, is connected with Demountable at the end of slip casting body 3 (i.e. the other end relative with the mouth of pipe 31) and connects body 4.This Demountable annexation is preferably slip casting body 3 and is threaded connection with being connected between the body 4, and slip casting body 3 is provided with sealing ring 6 with being connected between the body 4.Be equipped with rubber back-up ring 7 on slip casting body 3 and the junction outer wall that is connected between the body 4.
In conjunction with shown in Figure 2, when carrying out mortar depositing construction, specifying the slip casting position to hole first, then Grouting Pipe of the present invention is inserted in this hole, again slip casting body 3 is pulled back to chuck 5 and be limited to (being that taper plug 1 separates with slip casting body 3) on the mouth of pipe 31, follow unlatching with slip casting body 3 or be connected the grouting pump that body 4 connects, slurries input in the slip casting body 3 by grouting pump, last slurries carry out the slip casting operation by through hole 1, the mouth of pipe 31 successively, and while slurries also through hole 2 32 carry out the slip casting operation.
Above-described embodiment only is used for explaining inventive concept of the present invention, but not to the restriction of rights protection of the present invention, allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should fall into protection scope of the present invention.
