During installation, the steel section is fixed in the concrete at the end of the beam through the anchoring mechanism; one end of the traction rope is fixed to the fastening steel wire, and the other end of the traction rope enters from one side of the waterstop fixing ring and is led out from the other side of the waterstop fixing ring; the cavity of the steel section is cleaned and lubricated; the The fixing ring together with the traction rope in the fixing ring are pulled from one end of the corresponding steel cavity to the other end, so that the fixing ring of the waterstop is located in the cavity; fix the fixing ring end of the waterstop to the steel, insert the end of the fastening steel wire into the inner cavity of the fixing ring, pull the traction rope from the front end, and pass the fastening steel wire into the inner cavity of the fixing ring; remove the traction rope from the fastening steel wire, and when removing the waterstop, fix the hook of the traction mechanism to the end of the fastening steel wire; pull the fastening steel wire outward to pull the fastening steel wire out of the inner cavity of the fixing ring; pull the fixing rings on both sides of the waterstop out of the corresponding steel cavity; remove the fastening steel wire from the traction mechanism, the waterstop and the fastening steel wire are pulled from one end of the steel cavity to the other end, and no large construction space is required during construction. For 3 The 0mm~80mm modular telescopic device for highway bridges is installed in hot seasons, and the construction is more convenient and quick. The fixing ring is a "C" shape with an inner cavity and an opening on the side. In the process of pulling in the water stop strip alone, the fixing ring is deformed by force, which not only reduces the traction resistance and avoids the wear on the outside of the fixing ring. After the fastening wire is pulled in, the fixing ring is squeezed between the fastening wire and the outer wall of the cavity; the sealing effect is good, and the fastening wire is hard and not easy to deform, which avoids the fixing ring from falling out of the cavity due to pulling; installation and disassembly are more convenient; in order to reduce the resistance when the fastening wire is pulled in, the fastening wire can be a plastic-sprayed steel wire; secondly, because convex strips along the axial direction of the fixing ring are arranged at intervals on the outer side surface of the fixing ring, the convex strips The cross section of the strip is an arch or other shape. When the fixing ring is pulled into the cavity, the contact area between the fixing ring and the cavity is reduced, and the pulling resistance is reduced. When the fastening wire is pulled into the inner cavity of the fixing ring, the fixing ring is easier to deform and the pulling resistance is small. After the fastening wire is pulled into the inner cavity, the convex strip on the outside of the fixing ring fits more closely with the inner wall of the cavity, and the sealing effect is good. Thirdly, since a removal groove is provided on the cavity corresponding to the opening on the side of the fixing ring, the opening on the side of the fixing ring is in an "eight" shape. It also includes a removal tool, which includes a "C"-shaped blade body with a blade on at least one side, a fixed seat is provided behind the blade body, and traction wires are provided at both ends of the fixed seat, and the fixed seat is located in the removal groove.Fix the hook of the traction mechanism to the end of the fastening wire; pull the fastening wire outward to pull the fastening wire out of the inner cavity of the fixing ring; insert the traction wire of the disassembly tool from one end of the steel section into the other end of the steel section, so that the blade is located between the outer wall of the cavity and the outer side of the fixing ring of the waterstop, so that the fixing seat is located in the dismantling slide groove; pull the traction wire, and the traction wire drives the disassembly tool from one end of the steel section to the other end, and the disassembly tool peels the fixing ring off the steel section; pull the fixing rings on both sides of the waterstop out of the corresponding cavity of the steel section; remove the fastening wire from the traction mechanism. During long-term use, due to problems such as rubber aging, when the fixing ring of the waterstop is adhered to the cavity wall, direct pulling not only has great resistance, but also easily breaks the fixing ring of the waterstop, and it is not easy to pull out the fixing ring of the waterstop. Before the ring is removed, the outer surface of the fixing ring is firstly peeled off from the cavity wall with the blade of the removal tool, and then the fixing ring is pulled, which not only saves time and effort, but also the fixing ring is not easy to be pulled off, and it is more convenient to use; Fourthly, a pull ring is arranged at one end of the fastening wire, and the hook of the traction mechanism is hung on the pull ring, so that the fastening wire is pulled and disassembled more conveniently; Fifthly, since the cross section of the inner cavity is circular, the cross section of the fastening wire is circular, and the diameter of the fastening wire is slightly larger than the diameter of the inner cavity, the sealing effect is better; Sixthly, since an anchoring groove is arranged on the side of the steel section away from the cavity, an anchoring nut is arranged in the anchoring groove, and the anchoring screw of the anchor mechanism is threadedly connected with the anchoring nut, the connection is more convenient and firm; Seventhly, since a water collector is arranged under the water stop belt, the drainage effect is better. ; BRIEF DESCRIPTION OF THE DRAWINGS
