Embodiment

[0031] Such as figure 1 and figure 2 Shown, a kind of bonded flexible waterproof and drainage coiled material for highway and railway tunnel, comprises waterproof and drainage part, and more than one adhesive tape 4 that is longitudinally coated on one side of the waterproof and drainage part, and is covered with a A layer of isolation film 5, the adhesive tape is continuously coated on the waterproof and drainage part by scraping or rolling; the waterproof and drainage part includes the main board 1 of the waterproof board, and a plurality of raised ribs 2 longitudinally arranged on one side of the main board of the waterproof board , the groove between the raised ribs constitutes a drainage blind ditch 3, and the adhesive tape and the raised ribs are arranged on the same side. The adhesive tape divides it into more than two sections longitudinally along the waterproof and drainage part, and a whole piece of geotextile 6 is covered on the raised ribs in each section, and th...

Abstract

The invention discloses a bonded flexible water proof and drainage coiled material for a road and a railway tunnel and a laying method thereof. The coiled material comprises a water proof and drainage part and more than one bonding belt vertically coated one side of the water proof and drainage part. The water proof and drainage part comprises a main board of a water proof board and a plurality of protruding strip ridges vertically arranged on one side of the main board of the water proof board. Drainage blind drains are formed by grooves between the protruding strip ridges. The bonding belts and the protruding strip ridges are arranged on the same side. The bonded flexible water proof and drainage coiled material can closely adhere to an initial support. Even if a secondary lining pouring method from bottom to top is utilized, the gap generation at an arch portion is avoided, the mountain water of the initial support is discharged easily, and the water proof effect is good through the combination of the water tightness and the drainage. The drainage blind drains can be easily formed by geotechnical cloth. The blocking of the drainage blind drains and the puncture for the main board of the water proof board caused by sands and stones can be avoided through the filtration of the geotechnical cloth. The water proof board can be extended and transformed easily under outside strong extrusion or extension, and the damage to the main board of the water proof board can be prevented.

Description

technical field [0001] The invention relates to a bonded flexible waterproof and drainage coiled material for roads and railway tunnels and a laying method thereof, belonging to the field of road construction materials. Background technique [0002] At present, the waterproofing of highway and railway tunnels mainly lays waterproof membranes on the primary support surface, forms a sealed waterproof layer through waterproof membranes, and then pours a secondary lining concrete layer on the membrane layer. The method uses a waterproof coiled material as the waterproof layer, which has the advantages of good weather resistance and good water resistance. Traditional tunnel waterproofing membranes mainly use homogeneous sheets or composite sheets in structural design, and use anchor fixing method (hot-melt pad anchor welding) in construction, anchor-free laying method and hidden buckle tying method for hanging tunnel waterproof sheet Hanging method (lacing suspension method). ...
