Description
Technical Field
The utility model belongs to the technical field of box culvert movement joint seepage restoration and specifically relates to an assembled waterstop grout stagnant water structure is related to.
Background
In the diversion project, the cast-in-place reinforced concrete box culvert water delivery mode is adopted, in order to adapt to the influence of uneven settlement of a foundation and temperature change, deformation joints are arranged at certain intervals on the water delivery box culvert, and the leakage of the deformation joints is a great problem in the box culvert water delivery. The deformation joint is sealed from the inside, which is a more thorough solution for the water leakage treatment of the deformation joint, but some engineering water pressure is higher, the water leakage is sensitive, the internal construction conditions are poorer, and the requirements on the process and the contact surface are higher and the time consumption is long because the construction procedure is relatively complex, so that the engineering implementation is greatly restricted. Therefore, it is necessary to find a water stopping way which is simple and rapid in construction, simple and convenient to install, strong in sealing performance, short in time consumption, and good in adaptability and effect.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome not enough among the above-mentioned prior art, provide a sealed effectual, the convenient assembled waterstop grout stagnant water structure of being under construction.
The utility model discloses a realize through following technical scheme: the utility model provides an assembled waterstop grout stagnant water structure, includes the movement joint, the surface on movement joint both sides limit has the waterproof layer respectively to coat, the surface covering of waterproof layer has stagnant water belt layer, stagnant water belt layer's surface is provided with the pressure plate layer, the pressure plate layer left and right sides limit is provided with the bolt hole along vertical equidistant respectively, wear to be equipped with in the bolt hole and be used for passing the concrete box culvert of stagnant water belt layer and movement joint both sides downwards and hold the bolt of looks fixed, the middle part on pressure plate layer is provided with 2 at least grouting holes that are used for pouring into the polyurethane thick liquid.
The middle part of the water stop is provided with a round hole, and the water stop is made of rubber materials.
The upper end of the bolt is 2-3cm higher than the pressure plate layer.
The distance between the bolt holes is 25-35cm; the aperture of the bolt hole is phi 14-16mm; the hole depth of the bolt hole is 8-9cm.
