Detailed Description

The invention is described in further detail below with reference to the figures and the specific embodiments.

The air bag type water stop joint box for the underground continuous wall construction as shown in fig. 1 to 5 comprises a box body 1, a water stop mounting frame and an expansion air bag 5; the water stop mounting frame is arranged on the first vertical end face of the box body 1, and a water stop mounting groove for inserting a water stop is formed in the water stop mounting frame; the water stop mounting groove is vertical to the first vertical end face; a plurality of inflatable air bags 5 are arranged on the first vertical end surface. The water-stop joint box also comprises an air compression device 6, an air inlet and outlet control valve 7 and a rubber hose 8 which are sequentially communicated; the rubber hose 8 is also in communication with the inflatable bladder 5.

The waterstop mounting frame comprises two supporting plates 3 and two mounting plates 2 with the plate surfaces parallel and the space between the two mounting plates; the water stop mounting groove is a cavity between the two mounting plates 2; a plurality of expansion air bags 5 are evenly and symmetrically arranged on the first vertical end faces of the two mounting plates 2 which are opposite to each other. Two backup pads 3 incline respectively and locate two mounting panel 2's the opposite ends that carry on the back mutually, and 3 upper ends of backup pad are connected with the one end of mounting panel 2 back to first vertical terminal surface, and 3 lower extremes of backup pad are connected with first vertical terminal surface. The waterstop mounting bracket of this embodiment can be trapezoidal piece, and the upper end to the lower extreme of this trapezoidal piece are equipped with logical groove, should lead to the groove and cut apart into two right angle trapezoidal pieces of symmetry with former trapezoidal piece, should lead to the groove and be the waterstop mounting groove promptly. The waterstop mounting frame of the embodiment can also be two symmetrically arranged right-angle trapezoidal blocks or right-angle triangular blocks; the opposite end of the right-angle trapezoidal block or the right-angle triangular block is a vertical end face, a space is kept, and a cavity formed by the space is a water stop mounting groove.

Before the concrete wall body is poured, in the waterstop mounting groove that two mounting panels 2 formed were inserted to the waterstop (preferably rigid waterstop), the first vertical terminal surface of box 1 and the tip template parallel and level of waiting to pour concrete wall body, when pouring concrete, concrete wall body's tip is formed with the recess unanimous with the first vertical terminal surface of

box

1 and 3 profiles of backup pad, or the tip at concrete wall body is formed with the terminal surface of buckling in succession.
