Abstract

The invention discloses a grouting plug for a two-fluid process. The grouting plug comprises a slurry inlet pipe. An expansion pipe is arranged in the middle of the slurry inlet pipe and sleeves the outer side of the slurry inlet pipe, a slurry inlet pipe head is arranged on the expansion pipe and is communicated with the expansion pipe, a slurry return pipe is arranged on a side surface of the slurry inlet pipe, is of a T-shaped structure and is integrally connected with the expansion pipe, an end of the slurry return pipe is connected with a circular pipe ball plug, the circular pipe ball plug is fixedly connected with the outer side of the slurry return pipe by a hoop, a pipe core is arranged on a side surface of the slurry inlet pipe, one end of the pipe core is connected with the slurry inlet pipe by a return spring, a slurry overflow opening is connected to the other end of the pipe core and is communicated with the pipe core, sealing steel rings are arranged on the upper side surface and the lower side surface of the pipe core and sleeve the pipe core, and a stuffing pipe joint is arranged in the pipe core. The grouting plug for the two-fluid process has the advantages that the grouting plug can be widely used for pure-pressure grouting and circulation grouting in holes, and water can be freely discharged in the grouting holes, so that a plug body is free of head pressures, the plug can be lifted smoothly, dispersion of cement slurry can be effectively controlled, and the re-grouting frequency can be obviously reduced.

Description

Two-fluid process packer
Technical field
The present invention relates to a kind of packer, particularly a kind of two-fluid process packer.
Background technology
In hole, cycle grouting plug is generally for water conservancy project based process grouting construction, and the ground of most of buildings, water power and the hydraulic engineering dam foundation are processed in packer construction and all obtained general use.And in the process of construction in power station, be located in extremely frigid zones, under the higher ambient conditions of height above sea level, there are following two aspect problems: one, complex geologic conditions, curtain grouting region rock crushing, how roomy geology rock mass grow, connect crack, fill with again number of times more in work progress, grout consumption is large; Two, winter environment temperature is low, and slurries are long time of setting, can not normal termination, have a strong impact on construction speed.Therefore, extremely frigid zones processing roomy, that connect crack is the key point of this power station foundation treatment engineering.If slurry fluidity successively decreases comparatively fast, easily blocking pipeline, and cannot boost in filling process, there is construction safety hidden danger and hidden danger of quality.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problems referred to above, provide a kind of pure pressure that is widely used in to be in the milk, cycle grouting in hole, and the two-fluid process packer that can freely discharge water in grout hole.
To achieve these goals, the technical solution used in the present invention is such: two-fluid process packer of the present invention, comprise inlet pipe, inlet pipe middle part is provided with expansion tube, expansion tube is socketed in inlet pipe outside, expansion tube is provided with inlet pipe head, inlet pipe head communicates with expansion tube, inlet pipe side is provided with return pipe, return pipe is a T-shaped structure, and be connected with expansion tube one, return pipe one end adopts pipe bulb stopper to connect, pipe bulb stopper is fixedly connected with return pipe outside by clip, inlet pipe side is provided with tube core, tube core one end is connected with inlet pipe by back-moving spring, its other end is connected with the slurry mouthful that overflows, the slurry mouthful that overflows communicates with tube core, tube core upper side and downside are equipped with ring gasket, ring gasket is socketed on tube core, in tube core, be provided with and fill union, fill and on union, be connected with power transmission bearing, power transmission bearing with fill union and be rigidly connected, on power transmission bearing, be connected with observation valve, observation valve adopts transparent configuration.
Further, as a kind of concrete form of structure, the grout outlet place of return pipe of the present invention is provided with overfall valve.
Further, as a kind of concrete form of structure, inlet pipe grout outlet of the present invention place is provided with gas pipe nipple.
Further, as a kind of concrete form of structure, Dilated rubber hose opening part of the present invention is fixed with suspension ring.
Compared with prior art, the invention has the advantages that: two-fluid process packer of the present invention can be widely used in pure pressure grouting, cycle grouting in hole, and can in grout hole, freely discharge water, make cock body without head pressure, play plug smooth and easy, can effectively control the diffusion of cement grout, obviously reduce multiple filling number of times.
