Splicing paving method of waterproof plates in tunnel and splicing paving structure of waterproof plates in tunnel

Abstract

The invention relates to waterproof engineering in a tunnel, in particular to a splicing paving method of waterproof plates in the tunnel and a splicing paving structure of the waterproof plates in the tunnel. The method is characterized in that the splicing paving method of the waterproof plates in the tunnel belongs to a method applicable to the combination of waterproofing and water discharge. A traditional roof tile lap joint waterproof mechanism is utilized; a splicing paving method of the waterproof plates is improved; lap joint seams parallel to the water flow direction are adopted; on the basis of twice waterproofing measures of double-seam welding of the existing waterproof plates, one waterproof measure of adopting a joint seam which is parallel to the water flow direction and is not directly correlated to the welding quality of the waterproof plates is added; a multiple-protection-measure principle of the waterproofing in the tunnel is perfectly realized; the waterproof hidden danger can be effectively eliminated; and the waterproof effect of the joint seams is ensured. The paving technology of waterproof rolls in the longitudinal direction of the tunnel is adopted; an operation platform for a special trolley for waterproof plate pavement and a track walking technology are utilized; the horizontal operation in the same elevation platform and the continuous paving operation of the whole roll of the waterproof rolls can be realized; the work intensity of workers can be reduced; and the work efficiency for paving the waterproof plates is improved.

Description

technical field [0001] The invention relates to a tunnel waterproofing project, in particular to a splicing and laying method of a tunnel waterproof board and its structure, and is characterized in that it is suitable for a splicing and laying method of a tunnel waterproof board combined with waterproofing and drainage and its structure. Background technique [0002] Tunnel waterproof panels are generally spliced ​​and laid by waterproof membranes of a certain width and length, and the waterproof and sealing performance of the spliced ​​joints will directly affect the waterproof effect of the waterproof panels. [0003] At present, in engineering applications, the laying of tunnel waterproof panels mostly adopts the tunnel circumferential laying method. This method only needs to set a vertical joint perpendicular to the longitudinal direction of the tunnel between every two circumferentially laid waterproof membranes. , there is no need to set horizontal joints parallel to t...

AI Technical Summary

Problems solved by technology

[0004] The present invention adopts an improved method for the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the present invention is to eliminate the hidden danger of waterproofing of the joints of the waterproof board by improving the splicing and laying method of the waterproof board; the adopted technical solution is A splicing and laying method of tunnel waterproof board and its structure, using the traditional roof tile lap joint waterproofing mechanism, waterproof board joints adopt lap joints along the direction of water flow, so that groundwater can flow through the joints smoothly and avoid running water Water accumulation is formed at the seams to eliminate hidden dangers of waterproofing and ensure the waterproof effect of the seams
