Description

Putty type self-adhesive water-swelling water stop strip for grouting pipe

Technical Field

The utility model relates to a water stop strip, in particular to a putty type self-adhesive water-swelling water stop strip for a grouting pipe.

Background

The water-swelling sealing strip, also called a slow-swelling rubber sealing strip, is a strip-shaped rubber sealing material prepared by reacting natural rubber, an inorganic water-absorbing material and high-viscosity resin. The water stop strip is widely applied to construction joints, expansion joints and cracks of civil air defence, swimming pools, sewage treatment projects, underground railways, tunnels, culverts and the like and other concrete projects.

In the water-swelling sealing strip, the putty type water-swelling sealing strip has high swelling multiplying power and strong mobile replenishment, has strong balanced self-healing function after being placed in a construction joint, can automatically seal new tiny cracks caused by settlement, and can be used for stopping leakage again in finished engineering such as gap seepage and leakage. In the practical engineering application process, because of the use needs, what often used is to have the water-swelling stagnant water of slip casting pipe, and it is provided with a slip casting pipe in this internal in sealing rod, in the pre-buried seam of in-service use process, in case when the seepage demand repair appears in the seam, blocks up water through thick liquid butt joint slip casting.

Nevertheless current putty type water-swelling sealing rod still has certain not enough in structure and functionality, specific saying so, current slip casting pipe is the single tube structure, and the structure of sealing rod body itself is also comparatively simple, and the stagnant water performance is relatively poor, at the practical application in-process, the condition that the slip casting pipe is blockked up takes place easily, in addition, current swelling sealing rod formula design as an organic whole, because the inflation body is after the inflation of absorbing water, the deformation rate of absorbing water again can obviously descend, this makes when the gap position grow, the stagnant water effect of sealing rod can worsen, the infiltration phenomenon can take place.

In summary, the existing grouting pipe putty type self-adhesive water-swelling water stop strip has larger improvement space and requirement.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art and provides a grouting pipe putty type self-adhesive water-swelling water stop strip with double grouting pipes and an improved water stop strip body structure.

In order to achieve the purpose, the technical scheme adopted by the utility model is as follows: a putty type self-adhesive water-swelling water stop strip for a grouting pipe comprises a water stop strip body, a self-adhesive layer, a first grouting pipe and a second grouting pipe, wherein the self-adhesive layer is arranged on the water stop strip body; the first grouting pipe and the second grouting pipe are symmetrically arranged in the water stop strip body; the water stop strip body comprises a first putty type expansion body, a middle rubber body and a second putty type expansion body, wherein the first putty type expansion body, the middle rubber body and the second putty type expansion body are sequentially connected into a whole; the first putty type expansion body and the second putty type expansion body are symmetrically arranged on two sides of the middle rubber body; the first grouting pipe is arranged in the first putty type expansion body; the second grouting pipe is arranged in the second putty type expansion body; the middle rubber body is connected with the self-adhesive layer into a whole.

Furthermore, the first putty type expansion body and the second putty type expansion body are square.

Further, the middle rubber body is in a track shape.

Furthermore, the first injection molding pipe is circular, and the cross section of the pipeline is plum blossom-shaped.

The utility model utilizes the structural design of the symmetrical double-putty type expansion body, compared with an integral expansion body structure, the expansion of a single expansion body can be realized, meanwhile, the isolation is carried out by utilizing the middle rubber body, the isolation can be carried out when the single expansion body is damaged, the secondary plugging is carried out by utilizing the second expansion body after the isolation fails, and meanwhile, the design of the double grouting pipes can better ensure the completion of grouting.
