Technical Field

[0001] The invention belongs to the technical field of tunnel lining construction, and in particular relates to a positioning and installation device for a tunnel secondary lining waterstop. Background Art

[0002] In the tunnel construction quality, tunnel drainage is the focus and difficulty of construction quality, and the installation of tunnel waterstop is an important link in the tunnel drainage system. During the construction process, it is necessary to monitor the quality of the installation of the secondary lining waterstop of the tunnel under construction.

[0003] At present, the commonly used method is to fix the waterstop manually with wire, that is, after the secondary lining trolley is positioned and before the plug template is installed, the position of the waterstop is simply fixed with wire. This method causes great loss of wire, the workers are more random in construction, and the wire is very flexible, so it is difficult to ensure that the position of the waterstop remains unchanged. Therefore, it is difficult to ensure the accuracy and firmness of the fixed position during construction, which affects the installation quality of the tunnel secondary lining waterstop, thereby affecting the drainage of the secondary lining. Summary of the invention

[0004] In order to solve the problems in the above-mentioned background technology, the present invention provides a tunnel secondary lining waterstop positioning and installation device.

[0005] The technical solution of the present invention is: a tunnel secondary lining waterstop positioning and installation device, comprising a waterstop, a device body, a trolley template, bolts, and pipe fittings. The trolley template is provided with a fixing ring, and the fixing ring is provided with bolt holes. The bolts pass through the bolt holes to fix the device body to the trolley template. The device body is arranged on the trolley template at uniform and equal intervals in the circumferential direction. The device body comprises a connecting rod, a positioning rod, and a positioning ring. The connecting rod and the positioning rod are vertically connected to form a right-angle corner. The positioning ring is arranged at the right-angle corner. The connecting rod passes through the fixing ring to be connected to the trolley template. The pipe fitting passes through the middle of the positioning rings of multiple device bodies to form a ring with a radius greater than the trolley positioning radius. The waterstop is tied to the pipe fitting by steel wire.

[0006] According to a further solution, a scale is provided on the connecting rod.

[0007] According to a further solution, the connecting rod includes a sleeve, an extension tube, and a fastening nut. The extension tube is sleeved inside the sleeve. The sleeve is provided with a screw hole. The fastening nut passes through the screw hole to fix the sleeve and the extension tube.

[0008] According to a further solution, the connecting rod, the positioning rod and the positioning ring are welded together and are all made of hard metal material.

[0009] According to a further solution, the spacing between the device bodies is 1 m.

[0010] According to a further solution, the pipe fitting is a PVC pipe.

[0011] According to a further solution, the radius of the ring formed by the pipe passing through the positioning ring is the positioning radius of the trolley plus half the thickness of the second lining.

[0012] The advantages of the present invention are: during use, the device body is fixed on the second lining trolley by bolts, and the required size is adjusted by the ruler on the connecting rod, and then the device is evenly arranged at equal intervals in the annular direction, and the pipe fittings are passed through the positioning ring to form a ring. The position of the waterstop is fixed according to the ring formed by the pipe fittings, and the waterstop on the casting side is tied to the right-angle corner formed by the connecting rod and the positioning rod to ensure that the waterstop on the casting side remains vertical to the second lining plug template, thereby ensuring the accuracy and firmness of the fixed position. The size of the connecting rod of the present invention can be adjusted at any time according to demand, and the equipment can be reused many times, thereby reducing the amortization cost of the equipment. The structure is simple, and the detachable assembly method is used to facilitate the inspection and replacement of the present invention, thereby reducing the cost of equipment maintenance. The position of the waterstop can be flexibly adjusted, and the pipe fittings form a ring to position the waterstop, which effectively ensures the construction quality of the waterstop and facilitates the subsequent installation of the waterstop by the operating workers.
