Problems solved by technology

When the time for binding steel bars on the adhesive layer of the membrane exceeds its own weather-proof sealing safety (7~28 days), it will cause the adhesive sealing performance of the post-cast concrete and the pre-laid polymer film membrane adhesive layer to fail. , the above-mentioned "open water" under the waterproof layer will pass through the defects or damaged parts of the waterproof layer itself, and a large amount will enter between the waterproof layer and the structural concrete, and the open water will enter the structure at the structural cracks , resulting in engineering leakage

Abstract

The invention provides a fiber enhanced type wet paving/pre-paving waterproof coil material and a special construction method of the fiber enhanced type wet paving/pre-paving waterproof coil material for water prevention of an underground engineering bottom plate. The waterproof coil material comprises a fiber enhancing layer, an upper adhesive layer, a tread layer, a lower adhesive layer and an isolating membrane. The construction method comprises the following steps: (1) constructing a concrete cushion layer of the underground engineering bottom plate; (2) wetly paving a fiber enhanced type wet paving/pre-paving waterproof coil material; and (3) bundling bottom plate structure steel bars on the fiber enhancing layer and pouring bottom plate structure concrete. According to the fiber enhanced type wet paving/pre-paving waterproof coil material and the construction method, wet paving and pre-paving construction manners in a waterproof coil material construction process are combined together; a waterproof structure is simple, and waterproof and safe dual guarantees are realized; and the probability of water leakage is effectively reduced.

Description

technical field [0001] The invention relates to the field of underground engineering waterproofing, in particular to a fiber-reinforced wet-laying / pre-laying waterproof coiled material and a construction method thereof. Background technique [0002] In the field of underground engineering waterproofing, the construction method of waterproofing membranes is constantly developing with the development of waterproofing membranes. The waterproofing membranes have developed from ordinary membranes that cannot be bonded and sealed with structural concrete to post-cast concrete with structures. The corresponding construction method of the pre-laid waterproof membrane that forms a bonded interface that is sealed and does not "channel water" has also been continuously improved. [0003] The first is the ordinary membrane that cannot form a bonded seal with structural concrete and its construction method, such as the construction method of SBS modified asphalt waterproof membrane, whic...
