Abstract
The utility model discloses a piece of special grouting equipment for deformation joint leakage repairing. The special grouting equipment comprises a stirring grouting pipe, a grouting valve, a forwards and backwards spiral stirring rod, a water inlet valve, a water injection pump, a gel feeding valve and a grouting pump, wherein the gel liquid and the water are synchronously pressed into the stirring grouting pipe through the grouting valve; and the water feeding quantity is controlled by the water feeding vale so as to ensure that a reasonable weight proportion of the gel liquid and the water is obtained before grouting. As the two liquids are uniformly and automatically stirred by the forwards and backwards spiral stirring rod inside the stirring grouting pipe at a pressured state, two substantial technical defects of a grouting leakage plugging agent in the practical use process are solved; both the gel liquid and the water can be synchronously pressed in equal proportion and stirred automatically before grouting, so that the mixing ratio and the stirring uniformity of the gel liquid and the water are ensured, the reaction speed and the reaction thoroughness after the gel liquid is mixed with the water are stabilized, the leakage plugging effect of the CS-51 grouting leakage plugging agent to a deformation joint is greatly improved, the defects in a direct gel filling method are thoroughly solved, the operation is simple, the cost is relatively low, and the practicability is strong.
Description
[technical field]
The utility model relates to the grouting equipment that the repairing of underground building wall deformation joint seepage is used.
[background technology]
In the underground building, wall all is concrete structure, according to designing requirement, deformation joint (being commonly called as the shrinkage joint) when reaching certain distance, building length must be set, in order to prevent producing seepage at deformation joint, must in deformation joint, fill the binder that is formed by pitch and flax silk, behind its cooling curing, deformation joint is tamped, in order to prevent that filler from expanding outside seam, usually set up the rubber shelves water plate that is formed by pipe body and side plate at the exposed parts of deformation joint, outside the rubber watertight shutter, carry out again the beautifying and decorating of wall with decorative panel, thereby further improve leakage performance.The anti-leakage structure of this deformation joint, its leakage performance depend primarily on for the first time construction quality, if the lacking a sense of responsibility of constructor, the charges proportioning not to, construction technical data is not up to standard all can cause deformation joint seepage.In practice of construction, the percolation ratio of deformation joint is about 15%, even only have 1% percolation ratio, engineering also can't by check and accept, must be carried out antiseep to leakage and repair.Present state-of-the-art method for repairing and mending is to repair with the spirit of CS-51 grouting for water plugging, the spirit of CS-51 grouting for water plugging is to be developed by Co., Ltd of Suzhou City's division of construction institute, Suzhou Gusu Novel Building Materials Co., Ltd. produces, it is one-pack-type polyurethane chemical grouting loss circulation material, it meets the water immediate response, the volume rapid expanding generates water insolublely, and higher-strength and flexible gelinite are arranged.In actual use, have two critical defects: the proportioning of the first, CS-51 grouting for water plugging spirit glue and water is uncontrollable; Second before slip casting glue can not realize even the mixing with water; These two defectives will directly have influence on the reaction time of the two and generate the reaction mass of gelinite, thereby directly shadow is to the plugging leaks effect of deformation joint, the glue surface reaction can to occur too fast if glue and water do not stir, and glue inside because of not water reaction to occur insufficient, produce soft core phenomenon, stop up simultaneously Grouting Pipe, affect normal slip casting, more seriously because reaction is not thorough, cause false plugging leaks, time one is long, along with the hydraulic pressure increase of seepage floor can generation secondary seepage.Facts have proved that this antiseep method for repairing and mending can only be tabulated can not fundamentally solve leakage problems because the spirit of CS-51 grouting for water plugging must add before use a certain proportion of water and stir after normally slip casting and solidify leak stopping.Existing plugging leaks method is to inject leak stopping spirit glue in the single hole to offering in advance, and the seepage situation is different in the deformation joint, and first does not guarantee the mixing ratio of glue and water; Second does not realize that glue and water mix rear injection and solidifies, be difficult to guarantee plugging effect, although this method for repairing and mending can be dealt with examination, time one long still can seepage, this is the technical barrier that building trade is extremely had a headache.In order to capture this technical barrier of building trade, the applicant has found a kind of stifled drawing of effecting a radical cure deformation joint seepage to control the antiseep new method through for many years exploration and practice.Wherein, grouting equipment is one of key technology.
