The following describes embodiments of the present invention in detail with reference to the accompanying drawings, and the embodiments and specific construction processes of the present invention are given by implementing the embodiments on the premise of the technical solution of the present invention, but the scope of protection of the present invention is not limited to the following embodiments.
As shown in fig. 1-3, the first prefabricated part M1 and the second prefabricated part M2 are concrete prefabricated parts with working cavities with upper openings, and are assembled and connected together in a bolt connection mode during construction, and the assembly operation is underwater operation, so that a water stopping structure is required to be arranged at the bolt connection position to prevent water flow from leaking along the bolt holes in order to keep the dry environment in the working cavities.
Specifically, the guide passage and the intermediate seal member of the water stop structure of the present invention are generally manufactured together in the course of prefabrication of the member. Taking the first prefabricated part M1 as an example, two pre-buried steel pipes 11 are selected first, a connecting flange 12 is welded at one end of each pre-buried steel pipe 11, the two connecting flanges 12 are opposite, a rubber plate 13 is placed as an intermediate sealing member, and then bolts 14 are used for connection and fixation. Embedding the assembly at a preset connection position of the first prefabricated part M1, wherein the opening ends of the embedded steel pipes 11 are respectively flush with the outer surface of the first prefabricated part M1, namely, the two embedded steel pipes 11 form a first section penetrating through the first prefabricated part M1; similarly, an assembly of the same structure is installed in the second prefabricated element M2, constituting a second segment provided through the second prefabricated element M2. When assembled, the first section and the second section are coaxially and equiradially arranged to form a guide channel for installing the fastener.
The fastener comprises a screw 21 arranged in the guide channel and an end nut 22 matched with the screw, wherein the screw 21 is a double-ended screw with a cutting edge 23 (namely a puncture end) at one end, and the cutting edge 23 is an annular cutting edge with the diameter smaller than the inner diameter of the guide channel.
When the screw rod 21 is installed, firstly, the screw rod 21 is penetrated into the guide channel, the cutting edge 23 sequentially penetrates through the two rubber plates 13 (namely the middle sealing piece), then penetrates out from the other end, then, one end sealing piece is sleeved at two ends of the screw rod 21, the end sealing piece is a water-swelling rubber plug 25 with an end cover 24, the water-swelling rubber plug 25 is a conical plug matched with the inner diameter of the guide channel, and the diameter of the end cover 24 is larger than the outer diameter of the guide channel. Finally, a gasket is penetrated on the screw rod 21 and screwed and fixed by a nut 26, so that the water stop structure of the invention is installed.
