Detailed Description

Here, it is to be noted that the functions, methods, and the like related to the present invention are only conventional adaptive applications of the related art. Therefore, the present invention is an improvement of the prior art, which substantially lies in the connection relationship between hardware, not in the functions and methods themselves, that is, the present invention relates to a few functions and methods, but does not include the improvements proposed in the functions and methods themselves. The present invention is described for better illustration of the function and method for better understanding of the present invention.

As shown in fig. 1 and fig. 2, in an embodiment, the utility model provides a subway equipment district outer wall drainage structure, including the escape canal 100 of locating the outer wall bottom surface, the pre-buried rigid waterproof sleeve 200 that has vertical arrangement in escape canal 100 below, wear to be equipped with the drain pipe 300 in the rigid waterproof sleeve 200, the drain pipe 300 upper end is connected with the drainage floor drain 400 that sets up in rigid waterproof sleeve 200 upper end, it has rubber seal ring 800 of fixing in rigid waterproof sleeve 200 still to overlap on the drain pipe 300. The drainage ditch 100 arranged on the bottom surface of the outer wall is used for collecting accumulated water in regions such as the ground and the side, the accumulated water is collected after flowing into the drainage ditch 100, the rigid waterproof sleeve 200 embedded below the drainage ditch 100 can prevent the accumulated water from flowing out from the side, and the rigid waterproof sleeve 200 can prevent the internal drainage pipe 300 from being crushed by load, the drainage pipe 300 penetrating into the rigid waterproof sleeve 200 can drain the accumulated water in the drainage ditch 100, the accumulated water is drained into the drainage pipe 300 through the drainage floor drain 400, because the rubber water stop ring 800 has water absorption expansion performance, the expansion rate of the rubber water stop ring 800 after washing water can reach more than 220 percent, the leakage cracks between the concrete can be compacted by self water absorption expansion after encountering water, a good water stop effect is achieved, and the sealing performance of the drainage structure is improved. When the rigid waterproof casing 200 is pre-installed, the installation is performed by using the expansive cement.

As shown in fig. 1 and 2, since the rigid waterproof grommet 200 needs to be perforated through a wall at the time of installation. In this embodiment, the rigid waterproof casing 200 is sleeved with a rigid waterproof wing ring 900, and the rigid waterproof wing ring 900 is fixed on the rigid waterproof casing 200 by welding. The rigid waterproof wing ring 900 is suitable for structures where the pipeline penetrates through the wall and does not bear pipeline vibration and telescopic deformation, and structural strength is improved.

As shown in fig. 1 and 2, in order to prevent foreign materials from being discharged into the drain pipe 300 through the drain floor drain 400, a drain grate 500 is further installed at the water inlet end of the drain floor drain 400 according to the present embodiment. The main effect of drainage grate 500 is just playing the effect of filtering sewage, can detain the great filth of volume that partial ponding carried through the drainage grate, holds back the filth and can prevent that the pollutant from getting into the deposit of drain pipe 300, also reduces the ability of overflowing simultaneously, just probably leads to ponding scheduling problem, need clear up the foreign matter of accumulation on the drainage grate 500 at later stage.

As shown in fig. 1 and 2, when the drainage floor drain 400 is installed, the sealing performance should be ensured, and seeper leakage should be avoided, in this embodiment, a floor drain installation slot for installing the drainage floor drain 400 is arranged at the bottom of the drainage ditch 100, and an epoxy waterproof caulking compound 600 is filled between the periphery of the drainage floor drain 400 and the floor drain installation slot. Can stably install drainage floor drain 400 on the floor drain installation trench, waterproof caulking of epoxy 600, waterproof caulking of epoxy can play the effect of the fixed drainage floor drain 400 of bonding, fill the clearance between drainage floor drain 400 and the floor drain installation trench simultaneously, improve drainage structures's sealed effect, waterproof caulking of epoxy can have that bonding strength is good, elasticity is good, the ageing resistance, high low temperature resistant, long service life, advantages such as the construction is quick convenient can improve drainage structures's drainage effect.

As shown in fig. 1 and 2, since the drainage ditch 100 has an opening, the opening should be covered after the construction is completed, in this embodiment, a detachable stainless steel cover plate 700 is laid on the opening of the drainage ditch 100, and water passing holes are uniformly arranged on the stainless steel cover plate 700. Stainless steel cover plate 700 can shelter from 100 row's mouths in escape canal, and ponding can hold back the foreign matter of big specification simultaneously in the water hole converges escape canal 100, avoids escape canal 100 to block up.

As shown in fig. 1 and 2, the rigid waterproof tube 200 is pre-installed under the drain 100 in order to ensure the stability of the installation, and a fixing block 1000 is installed under the rigid waterproof tube 200 and is placed against the lower end of the rigid waterproof tube 200, and a plurality of fixing bolts 1100 are installed on the fixing block 1000 around the circumference of the rigid waterproof tube 200.
