Description
Technical Field
The utility model belongs to the technical field of subway engineering's structure, concretely relates to a waterproof construction that is used for open cut station main part and attached junction.
Background
Subway engineering is mostly located underground, receives groundwater influence very big, and waterproof requirement is high, and the construction degree of difficulty is big, and the influence factor is many, and waterproof construction is difficult to control, and subway seepage, water leakage phenomenon are comparatively general. The subway leakage water has great influence on the subway construction and operation, and on one hand, the subway leakage water needs to be repaired by spending a large amount of manpower and material resources, so that the subway construction cost is increased; on the other hand, the service life of the subway is influenced by the leakage water of the subway, the riding environment is influenced, and the quality hidden danger is brought to the station; leakage water during the operation period of opening the subway generates huge maintenance cost, and increases the operation cost of the subway. Subway waterproof control becomes the central importance of subway quality control. At present, the waterproof concept of the subway is that the structure is mainly self-waterproof, and the outer waterproof is assisted, namely, the waterproof concrete of the main structure is taken as a main waterproof means, the full outer waterproof of coiled materials, coating materials and the like is taken as an auxiliary means, and a waterproof reinforcing means is adopted at the weak points (structure seams, reserved parts, structure transformation positions and the like) of the structure.
The construction joint is used as a weak point of a structure and is easy to leak water, a 'serious disaster area' of the water leakage is arranged at the joint of a main body structure and an auxiliary structure of a survey station, the position has the problem of overlapping of new and old concrete due to different construction time sequences and is influenced by a fender post, and the general waterproof method mainly adopts water swelling and sealing glue and a pre-buried grouting pipe as waterproof measures. However, the water-swelling waterproof glue is an amorphous waterproof material, and the waterproof effect of the joint is affected by the problems of extrusion, uneven thickness, unclean base surface cleaning, early swelling in case of water and the like in site construction; reserve the slip casting pipe and also often appear buried depth not in place, the slip casting pipe scheduling problem that is obstructed, and additional structure foundation bearing capacity is inhomogeneous etc. all can reduce deformation joint department waterproof ability, finally leads to the structure to appear the percolating water. Therefore, the traditional waterproof method for the joint of the main structure and the auxiliary structure of the station has a plurality of disadvantages.
