Embodiment Construction
[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings, which are explanations rather than limitations of the present invention.
[0032] Such as figure 1 and 3 As shown, a positioning device for hot-melt gaskets of tunnel waterproof boards includes three sets of rulers. The set of rulers 2 is composed of a plurality of measuring rulers layer by layer. And the end, the first end is a free end, and the measuring ruler of the inner layer can be stretched along the free end to adjust the length of the set of rulers.
[0033] The cross-section of the measuring ruler is rectangular, and the three sets of rulers are connected end to end in sequence, and the three side walls connected in turn form an equilateral triangle; The vertical side is close to a vertical side at the head end of another set of rulers, and the tops of two adjacent sets of rulers form a concave vertex.
[0034] Such as figure 2 As shown, an equil...

The invention discloses a positioning device for hot-melt gaskets of tunnel waterproof boards, which comprises three sets of rulers. The sets of rulers are composed of layers of measuring rulers. One end of the sets of rulers is a closed end, and the other end is a closed end. It is a free end, and the measuring ruler in the inner layer can expand and contract along the free end of the set of rulers; the three sets of sets of rulers are connected head to tail to form an equilateral triangle structure. The end of the layer measuring ruler is hinged with the end of the innermost measuring ruler at the free end of another set of rulers. The positioning device can achieve low cost and easy operation on the premise of meeting the precision required by the construction, and can simplify the original cumbersome fixing procedure of the hot-melt gasket, thereby greatly improving the laying progress of the geotextile waterproof board.
Description
technical field [0001] The invention belongs to the field of tunnel construction equipment, and in particular relates to a positioning device for hot-melt gaskets of tunnel waterproof boards. Background technique [0002] Leakage of tunnels is the focus and difficulty of current design and construction. Once water leakage occurs in tunnels, it will directly affect the quality of the main structure of the project and the safety of use. During the construction of highway tunnels, the design and construction of the new Austrian method has been generally adopted. For waterproofing in the cave, a waterproof board is laid between the primary support and the secondary lining layer, and a buffer layer of non-woven geotextile is laid between the waterproof board and the primary support surface. The waterproof board is hung after the non-woven geotextile is laid. When laying the waterproof board, fix the waterproof board to the predetermined position, and then heat it with a manual e...
