Embodiment Construction

[0027] refer to Figure 1 to Figure 4 , the invention relates to a splicing and laying method of a tunnel waterproof board, comprising the following steps:

[0028] (1) After the special trolley for laying the waterproof board 1 is in place and the base surface of the tunnel initial support 3 is leveled, lay the non-woven geotextile 2 on the base surface of the initial support 3 . Use nails to fix the thermoplastic gasket and non-woven geotextile 2 on the base surface smoothly and closely, with a distance of 50 cm between the fixing points, and the lap width of the non-woven geotextile 2 is not less than 5 cm.

[0029] (2) Before laying the tunnel vault waterproof membrane, carry out accurate lofting of the tunnel vault waterproof membrane. Mark the longitudinal tunnel centerline 9 at the tunnel vault position, and mark the laying and lofting lines of the two long sides of the waterproof membrane according to the width and length of the waterproof membrane.

[0030] (3) Use ...

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...
