Description
Technical Field
The utility model relates to a connection form between current situation escape canal and inspection shaft. Is suitable for the field of municipal water supply and drainage.
Background
Common drainage ditches can be divided into open ditches, cover plate ditches and closed ditches according to the section form, wherein the open ditches are drainage ditches without ditch cover plates except for the water dispersion slope of the outer wall of the house, and can quickly and organically guide ground water and rainwater to a downstream pipeline. The cover plate ditch reduces the entry of sundries by adding the cover plate above the open ditch on the premise of ensuring that water and rainwater on the road surface can enter the ditch. The blind ditch is a ditch buried under the ground to guide water flow, and can be generally connected with a downstream municipal drainage system due to the fact that covering soil with a certain thickness is arranged right above the blind ditch.
The open ditch or the cover ditch has the condition that the open ditch or the cover ditch cannot be connected in the same direction when being connected to a downstream drainage system because the surface of the open ditch or the cover ditch is not covered with soil. At this time, a certain modification is needed before the drainage ditch is accessed into the inspection well. The common practice in the prior art is to arrange a floor drain at the end of the drainage ditch and connect the drainage pipe with the downstream inspection well. The connection form is easy to generate clogging at the grate of the floor drain, waste is easy to decay at the floor drain, and a pipeline at the downstream of the floor drain is usually smaller than a water passing section of an upstream water outlet, so that the water body overflowing capacity is seriously influenced.
Chinese patent publication No. CN 206635915U discloses a connection structure between an open drain ditch and a drain pipe, the connection structure is a linking pipe with an opening on a side wall of a non-section of the open drain ditch, a grate is arranged at the opening of the linking pipe, the direction of the linking pipe is consistent with the direction of the open drain ditch, the drain pipe is inserted into the tail end of the linking pipe, and the drain pipe and the inner wall of the tail end of the linking pipe are sealed and fixed by waterproof mortar. This prior art can realize the separation of solid waste and water, but because pipeline and open drain ditch are the form of following the way and connecing, downstream pipeline earthing can't satisfy the requirement, when needs cross pavement or road, the connecting pipe is damaged by the influence of ground load easily in the in-service use, and seals through waterproof mortar between drain pipe and the terminal inner wall of adapter pipe and fix insecure.

The well lid is all equipped with at the bottom of falling inspection shaft and current situation inspection shaft top, and the well inner wall that corresponding inspection shaft is pressed close to the well lid is arranged, is equipped with the cat ladder that corresponds corresponding well lid in bottom of falling inspection shaft and current situation inspection shaft.
The current situation escape canal coats and is stamped the apron.
The utility model has the advantages that: the utility model discloses a set up the inspection shaft that falls at the bottom, filth and sewage separation in the escape canal, the filth deposits in the inspection shaft bottom that falls at the bottom, and sewage then flows from the connecting pipe of inspection shaft lateral wall that falls at the bottom to the stainless steel grid that accessible mouth of pipe department set up carries out the separation of solid waste and water.
The utility model discloses well pipeline does not have the elbow design, has avoided among the prior art tiny precipitate of elbow department of floor drain pipe to pile up the phenomenon, has enlarged the rivers section of pipeline, makes sewage discharge more smoothly.
The utility model discloses adopt waterproof sleeve pipe to seal fixedly when china communicating pipe is connected with the wall of a well, can ensure the leakproofness.
The utility model discloses can't be in the same direction as connecing when advancing the current situation inspection shaft in the current situation escape canal, adopt and fall to the ground the inspection shaft switching, reduce the connecting pipe elevation simultaneously, make its buried depth increase, can effectively avoid the pipeline when crossing pavement or road, the connecting pipe receives the ground load influence and is damaged.

Detailed Description
As shown in fig. 1 to 3, the present embodiment is a connection form between a current drainage ditch and an inspection well, and includes a current drainage ditch, a bottom inspection well and a current inspection well, wherein the current drainage ditch is covered with a cover plate to form a cover plate ditch, and the end of the cover plate ditch is connected to the upper part of the bottom inspection well; a water inlet communicated with the cover plate ditch is formed in the side wall of the upper part of the bottom falling inspection well, and a water outlet is formed in the side wall of the middle part of the bottom falling inspection well; the current drainage ditch is provided with a water inlet on the side wall of the middle part and a water outlet on the side wall of the lower part.
In this example, the water inlet of the present drainage ditch is slightly lower than the water outlet of the bottoming inspection well, and the water outlet of the bottoming inspection well is communicated with the water inlet of the present drainage ditch through a communication pipe. When the communicating pipe is connected with the bottom-falling inspection well and the current situation inspection well, the communicating pipe is sealed and fixed by a waterproof sleeve, so that the sealing performance can be ensured.
In this embodiment, the water outlet of the falling-bottom inspection well is provided with a stainless steel grating, the distance between the grating bars is 30mm, and the solid waste entering the current inspection well is filtered, so that the solid waste entering the current inspection well is greatly reduced, and the operation efficiency of the current pipe network system is improved.
In the embodiment, the communicating pipes are obliquely and downwards obliquely arranged from the end of the falling inspection well to the end of the current inspection well, and the gradient is 3 per thousand, so that the normal flow of water flow is facilitated. The soil covering thickness of the communicating pipe 6 is 0.7m, if the soil covering thickness of the communicating pipe 6 is limited by current conditions, the requirement of the lowest soil covering of 0.7m cannot be met, the burial depth can be properly reduced, and the pipeline is encapsulated in a reinforced concrete square bag mode, so that the ground load bearing capacity of the pipeline is improved.
The distance between the bottom of the floor inspection well and the water outlet on the side wall of the floor inspection well can be 0.3m, 0.4m or 0.5m, and the appropriate height can be selected according to the actual conditions such as the depth, the flow rate, the solid dirt content and the like of the current drainage ditch.
