Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] Such as figure 2 , 3 As shown, the suction cup device 13 for waterproof board construction includes a suction cup body 11 made of soft materials (such as TPU (polyurethane), nitrile rubber, etc.), and a protruding handle 10 is provided on the back of the suction cup body 11 .

[0032] The suction cup body 11 is connected to the fixing part 7, the fixing part 7 is cylindrical, and one end thereof is open, and the handle 10 is clamped in the opening, so as to connect the suction cup body 11.

[0033] The other end of the fixing member 7 is provided with an end face 8, and the end face 8 is provided with a nail hole 9 for fixing the fixing member 7 on the contour surface of the tunnel. The end surface 8 provided with the nail hole 9 is concave, and the concave end surface 8 is made of a material with certain elasticity, so that...

Abstract

The invention discloses a sucker device for waterproof board construction and a tunnel waterproof board construction method. The sucker device comprises a sucker body made by a soft material, and a fixing member, a protruding handle is arranged on the back of the sucker body, the sucker body is connected at one end of the fixing member through the handle, a fastener hole is arranged at the other end of the fixing member, and an adhesive is coated on the adsorption surface of the sucker body. During laying, geotechnical cloth is laid on a tunnel profile face, the fixing member of the sucker device is fixed outside the geotechnical cloth by enabling a fastener to penetrate the fastener hole, the handle of the sucker device is connected on the fixing member in a clamped manner, release paper on the surface of the sucker body is torn off, a waterproof board is upwards jacked and pressed on the sucker body of the sucker device to enable the sucker body to suck the waterproof board, and then the waterproof board is fixedly connected to complete laying of the waterproof board. The waterproof board can be fixed by only pressing the waterproof board on the sucker device when the waterproof board is lifted by adopting the sucker device, so that steps for welding and fixing the waterproof board are not needed.

Description

technical field [0001] The invention relates to a sucker device, in particular to a sucker device for waterproof board construction. The present invention also relates to a tunnel waterproof board construction method using the suction cup device. Background technique [0002] In the process of tunnel construction, the construction of waterproof board is an important link. In the construction of tunnel waterproof board suspension, it is necessary to fix the waterproof board with the tunnel excavation contour before concrete molding. There are two main methods currently used. The hot melt gun is welded with the suspension point behind. [0003] The lashing strap reserved behind the waterproof board is tied to the fixed point. Due to the limitation of the process, the construction is very difficult. After the waterproof board is unfolded, the lashing strap is located behind the waterproof board, and it is very difficult for the operator to do it. Simultaneously, can't satisf...
