Technical Field
The utility model relates to the technical field of building construction, in particular to a waterproof structure of a horizontal construction joint of a side wall in a cover-excavation top-down construction method.
Background
In the cover and dig reverse construction process, the side wall structure construction order is executed after every layer of roof and bottom plate structure construction in the underground finishes, so the side wall structure can form twice horizontal construction joint from top to bottom, and wherein the bottom construction joint returns a welding stagnant water steel sheet to set up on pouring, and upper strata horizontal construction joint is because the shoulder bottom of stopping need set up the template and prop up and establish the system, can't weld stagnant water steel sheet, need carry out the stagnant water measure of other modes.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects in the prior art, and provides a waterproof structure for a horizontal construction joint of a side wall of a cover-excavation top-down construction method.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a cover waterproof construction of horizontal construction joint of reverse construction method side wall, includes that the mould builds the concrete wall and stops and shoulder the concrete wall, the mould is built the concrete wall and is located the below of stopping and shoulder the concrete wall, and the mould builds the concrete wall and stops and be provided with upper horizontal construction joint between the shoulder the concrete wall, the bottom of stopping and shoulder the concrete wall reserves the recess, has placed trapezoidal stagnant water adhesive tape in the recess, the pre-buried grout pipe that has in top of mould construction concrete wall.
Preferably, the size of the grooves is 20mm by 10 mm.
Preferably, the bottom of trapezoidal stagnant water adhesive tape is the wave setting for increase stagnant water route length, increase the contact time of the water that gets into horizontal construction joint and water-swelling stagnant water adhesive tape, further strengthen the stagnant water effect of water-swelling stagnant water adhesive tape, and trapezoidal stagnant water adhesive tape is PJ400 type water-swelling stagnant water and glues.
Preferably, the grouting pipe is connected with a three-way pipe, the three-way pipe extends to the outside of the molded concrete wall and is connected with a pressure type grouting machine.
Preferably, the top of the molded concrete wall is welded with a water stop steel plate.
According to the waterproof structure of the horizontal construction joint of the side wall in the cover-excavation reverse construction method, when a template is erected at the middle position of the bottom of a shoulder-stopping concrete wall, a 20 x 10mm batten is longitudinally customized in the middle of the template along the groove of the shoulder-stopping concrete wall, a formwork support system is arranged below the template, the template is disassembled after the strength of concrete reaches the design strength, all battens are chiseled, a PJ400 water-swelling waterproof glue is filled in the groove and protrudes out of the concrete surface by no less than 5mm, 8-12mm full-section grouting pipes are symmetrically arranged on two sides of the groove, a three-way pipe is adopted to lead the outer side of the side wall to be no less than 500mm, and after the construction of the side wall is finished and the design strength is reached, a pressure type grouting machine is adopted to perform grouting, so that the waterproof effect of the construction joint is ensured.
