[0024] In order to make those skilled in the art better understand the technical scheme of the utility model, the utility model will be further described in detail below with reference to the drawings.
[0025] Please refer to Figs. 1-2 A kind of deformation joint structure of underground subway station construction, including middle buried waterstop 1 being arranged in the middle position of deformation joint structure, joint filling material 2 is arranged in the upper and lower positions of middle buried waterstop 1 in deformation joint structure, outer-pasted waterstop 3, waterproof reinforcing layer 4 and coiled waterproof layer 5 are sequentially arranged from top to bottom below deformation joint structure for waterproof, above is the conventional structure of deformation joint in prior art, still include:
[0026] First water channel structure, it is arranged in the joint filling material 2 top of deformation joint structure and located in the top of joint filling material 2 above middle buried waterstop 1 to collect the water seepage in the top of joint filling material 2 to carry out drainage, more avoid the risk of water seepage diffusion in the top of joint filling material 2;And
[0027] Second water channel structure, it is arranged in the upper of deformation joint structure, first water channel structure is located in the inner side position of second water channel structure, second water channel structure is used to collect the water seepage from the upper of first water channel structure to carry out drainage, second water channel structure belongs to secondary insurance measure, in the case where first water channel structure cannot completely block water seepage, through second water channel structure, increase the water-collecting, water-lead intensity above deformation joint, avoid the serious diffusion of water seepage.
[0028] Further, first water channel structure and second water channel structure are arranged below the concrete top surface on both sides of deformation joint, to flatten concrete top surface structure, avoid occupying too much space.
[0029] Further, the first water channel structure comprises a first drainage channel 6 for collecting water seeping from the joint filling material 2 and draining the water to a drainage position such as a sewer, the top surface and the bottom surface of the first drainage channel 6 are both upwardly bent structures, the bent raised portions are arranged along the extension direction of the first drainage channel 6, the top end of the joint filling material 2 extends to the bottom surface position of the first drainage channel 6, because the main function of the deformation joint is to have the ability to adapt to deformation, the top surface and the bottom surface of the first drainage channel 6 in the transverse direction are designed to be bent structures, when the first drainage channel 6 receives a pressing force in the central direction, the first drainage channel 6 can continue to bend and deform to adapt to the deformation condition of the deformation joint position;
[0030] The bent portion of the bottom surface of the first drainage channel 6 is provided with an opening 7, the opening 7 is arranged along the extension direction of the first drainage channel 6, a stainless steel water seepage net 8 is arranged in the opening 7, the stainless steel water seepage net 8 is in contact with the top portion of the joint filling material 2 and can enable the water absorbed in the joint filling material 2 to seep into the first drainage channel 6 through the stainless steel water seepage net 8 to achieve water collection and further drainage. At the same time, because the bottom surface of the first drainage channel 6 is bent, the water seeping into the first drainage channel 6 through the stainless steel water seepage net 8 naturally flows to both sides of the first drainage channel 6 and does not flow back to the joint filling material 2, so that the drainage is more thorough.
[0031] Further, the first drainage channel 6 is provided with a pre-embedded steel plate 9 on both sides, the pre-embedded steel plate 9 is pre-embedded in the concrete on both sides of the first drainage channel 6.
