Embodiment Construction

[0020] The following is further described in detail through specific implementation methods:

[0021] The reference signs in the accompanying drawings include: first channel steel 10, second channel steel 11, first through hole 12, second through hole 13, spacer 14, U-bolt 15, first nut 16, second Nut 17, the second screw rod 18, steel wire rope 19, middle buried waterstop 21, connecting plate 31, the third screw rod 32, inverted arch 5, short side wall 6.

[0022] A fixture for waterstop buried in a tunnel invert, such as figure 1 and figure 2 As shown, it includes a clamping piece and several connecting pieces. The clamping piece includes a first channel steel 10 and a second channel steel 11 with the same specifications. Both the first channel steel 10 and the second channel steel 11 are No. 10 channel steel. The waists of a channel steel 10 and the second channel steel 11 are close to each other, and the upper leg of the first channel steel 10 is provided with three fir...

Abstract

The invention relates to the technical field of tunnel construction equipment, in particular to a clamp for burying a water stop belt in a tunnel inverted arch. The clamp for burying the water stop belt in the tunnel inverted arch comprises a clamping piece and a plurality of connecting pieces, and the clamping piece comprises first groove steel and second groove steel; a plurality of first through holes are formed in an upper leg of the first groove steel, and second through holes corresponding to the first through holes are formed in an upper leg of the second groove steel; positioning frames are correspondingly arranged below the first groove steel and the second groove steel, and the connecting pieces comprise U-shaped bolts; positioning mechanisms are arranged at one ends of the U-shaped bolts, and second nuts are welded to the ends, penetrating through the second through holes, of the U-shaped bolts; and second threaded rods are connected to the second nuts in a threaded mode. According to the scheme of the clamp for burying the water stop belt in the tunnel inverted arch, the problems that in the prior art, installation and disassembly of a buried water stop clamp are inconvenient, and a clamp cannot be used and recycled are solved.

Description

technical field [0001] The invention relates to the construction field of tunnel inverted arch waterstops, in particular to a clamp for buried waterstops in tunnel inverted arches. Background technique [0002] In the quality of tunnel construction, tunnel waterproofing and drainage is the focus and difficulty of construction quality, and the installation of tunnel inverted arch waterstop is an important link in the tunnel waterproofing and drainage system. At present, most of the fixtures for buried waterstops in the short side walls of inverted arches of tunnels are composed of welded steel bars and other profiles. This kind of welded fixtures for buried waterstops is inconvenient to install and dismantle, and cannot be used repeatedly. Contents of the invention [0003] The object of the present invention is to provide a fixture for buried waterstops in tunnel inverts, which is used to install mid-buried waterstops in the short side walls of tunnel inverts, so as to sol...
