Description

Rainwater inspection shaft is used in sponge city

Technical Field

The utility model relates to a rainwater processing technology field, in particular to sponge is rainwater inspection shaft for city.

Background

The sponge city is a new generation of urban rainfall flood management concept, and means that the city has good elasticity in the aspects of adapting to environmental changes, coping with natural disasters caused by rainwater and the like. When raining, the device absorbs water, stores water, seeps water and purifies water, and releases and utilizes the stored water when needed. The core idea of sponge city construction is to maintain hydrological characteristics unchanged before and after field development and realize benign hydrological cycle of cities. The rainwater well is built in the sponge city and often needs to be built, the rainwater well in the existing structure is usually connected with the drainage pipeline at a right angle, when rainwater is large, vortex is easily formed to influence the drainage efficiency, and although part of the rainwater well joints adopt arc transition, the arc is easily broken or collapsed in the long-time use process to influence the normal use of the drainage pipeline.

Furthermore, the length of the supporting rod is adjustable.

Furthermore, the support rod comprises a first rod body and a second rod body which is connected with the first rod body in a threaded mode.

Furthermore, a dirt intercepting frame is hung at the top end of the well.

Furthermore, a boss is arranged in the well above the sleeve, and the sewage intercepting frame is erected on the boss.

Further, cut dirty frame and include annular frame, and enclose and construct in hemispherical filter screen on the frame, the frame set up in on the boss.

Compared with the prior art, the utility model discloses following advantage has:

(1) sponge is rainwater inspection shaft for city, through adopting the circular arc transition with well and drainage pipe junction, and then can avoid the production of vortex, improve drainage pipe's drainage efficiency, and through set up the sleeve pipe in the junction, and then erode the circular arc when can avoiding the rainwater to flow through, and the sleeve pipe still can support the junction, improves the structural strength of junction, has improved the life cycle of junction.

Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

The embodiment relates to a rainwater inspection well for sponge city, as shown in fig. 1 combined with fig. 2 and fig. 3, the rainwater inspection well comprises a well 2 connected to a drainage pipeline 1, the joint of the well 2 and the drainage pipeline 1 is in arc transition, the rainwater inspection well for sponge city further comprises a sleeve 3 supporting the arc of the joint of the well 2 and the drainage pipeline 1, and the sleeve 3 is made of stainless steel.

In the above structure, the hoistway 2 is formed by stacking bricks, and a detachable manhole cover 201 is provided on the top thereof. Well 2 is 90 circular arc transition with two junctions of drainage pipe 1 to the swirl of reducible here improves drainage pipe 1's drainage efficiency, owing to long-time rain wash, the circular arc of junction is very easy to be out of shape or collapses, thereby causes drainage pipe 1's use, in order to prevent above-mentioned condition to appear, sets up foretell sleeve pipe 3 in the junction in this embodiment, so that sleeve pipe 3 bears the washing out when rainwater flows. In the concrete structure, the whole casing 3 is horn-shaped, the peripheral surface of the casing is bonded on the circular arc of the joint through concrete, the small-diameter end of the casing is connected with the drainage pipeline 1, and the large-diameter end of the casing is communicated with the well 2.

In order to prevent the sleeves from falling off in the long-term use process, as shown in fig. 1 and fig. 2, in this embodiment, a support rod 4 is disposed between two sleeves 3, so that the support rod supports the two sleeves 3, in a specific structure, a slot 5 is formed on an end surface of a large-diameter end of a sleeve 3 in this embodiment, and when in use, two ends of the support rod 4 are respectively inserted into the corresponding slots 5 of the two sleeves 3, so as to form a support. In this embodiment, the number of the slots 5 may be a plurality of slots arranged at the end of the ring sleeve 3, and is preferably four slots arranged in a matrix, and the matrix arrangement mode can avoid blocking when workers go into the well.

The length of the supporting rod 4 is adjustable in the embodiment, and the structure with the adjustable length is adopted, so that on one hand, the supporting force can be adjusted conveniently by changing the length of the supporting rod, and on the other hand, the supporting rod can also be adapted to the wells 2 with different diameters. In this embodiment, the supporting rod 4 includes a first rod 401 and a second rod 402 screwed with the first rod 401, and when the length of the supporting rod 4 needs to be adjusted, the first rod 401 and the second rod 402 rotate relatively.

In order to avoid the drainage blockage caused by the impurities falling into the well 2 through the well lid 201, in the embodiment, the sewage blocking frame 6 is hung at the top end of the well 2, the sewage blocking frame 6 comprises an annular frame 601 and a hemispherical filter screen 602 enclosed on the frame 601, and in order to facilitate the arrangement of the sewage blocking frame 6, in the embodiment, a boss 7 is arranged in the well 2 above the sleeve 3, and the frame 601 is only erected on the boss 7. In addition, in this embodiment, a filter layer 8 is further disposed at the bottom of the well 2, the filter layer 8 may be a cobble layer, and by disposing the filter layer 8, the stored water at the bottom of the well can be filtered and then flows to the ground surface.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
