Description

Technical Field

[0001] This utility model relates to the field of municipal engineering facilities technology, and in particular to a rainwater collection well designed to prevent settling. Background Technology

[0002] In municipal road drainage systems, rainwater collection wells are critical infrastructure, and their stability directly affects drainage efficiency and road lifespan. Traditional rainwater collection wells often employ brick walls with a concrete capping structure. However, after long-term use, the backfill soil is prone to uneven settlement, leading to well tilting, road collapse, and drainage failure. Existing improvement solutions mainly focus on enhancing the well's own strength, such as increasing concrete thickness or steel reinforcement density, but they fail to address the issue of coordinated deformation between the well and the backfill soil. Therefore, a settlement-resistant rainwater collection well has been developed. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a rainwater collection well that prevents settling, so as to solve the problems pointed out in the background art.

[0004] To achieve the aforementioned objectives of this utility model, the technical solution adopted is as follows:

[0005] A rainwater collection well designed to prevent settlement includes a well body and a concrete capping at the top of the well body, as well as an anti-settlement backfill structure. The anti-settlement backfill structure includes a ring-shaped steel reinforcement strip around the well and a layered compacted soil layer. The ring-shaped steel reinforcement strip is embedded in the concrete capping and includes longitudinal and transverse steel bars arranged perpendicularly to each other. The two ends of the longitudinal and transverse steel bars extend outward from the concrete capping to form an outer anchoring section and extend inward from the concrete capping to form an inner anchoring section, respectively. The length of the outer anchoring section is ≥460mm, the length of the inner anchoring section is ≥240mm, and the total length of the longitudinal and transverse steel bars is ≥700mm. The outer and inner anchoring sections are wrapped by the layered compacted soil layer during well backfilling to form a three-dimensional anchoring system.

[0006] As a further improvement of this utility model, the well body includes a soil base layer, a concrete cushion layer and a well wall arranged sequentially from bottom to top.

[0007] As a further improvement of this utility model, the soil base is a 200mm thick 3:7 lime-soil base, the concrete cushion is a 100mm thick C20 concrete cushion, the well wall is a MU10 brick well wall, and the thickness of the concrete coping is 150mm.

[0008] As a further improvement of this utility model, the diameter of both the longitudinal and transverse reinforcing bars of the well perimeter annular steel reinforcement strip is 12mm.

[0009] As a further improvement of this utility model, 6-10 longitudinal reinforcing bars are provided, and the starting end of the longitudinal reinforcing bars is 35-80mm away from the edge of the inner wall of the well wall; 4 transverse reinforcing bars are provided, and the starting end of the transverse reinforcing bars is 80mm away from the edge of the inner wall of the well wall.

[0010] As a further improvement of this utility model, the well body is a single grate structure, with the well wall having dimensions of 750mm × 1160mm × 860mm. The number of longitudinal reinforcing bars is 6, the spacing between the longitudinal reinforcing bars is 200mm, and the starting end of the longitudinal reinforcing bar is 80mm from the edge of the inner wall of the well wall. The number of transverse reinforcing bars is 4, the spacing between the transverse reinforcing bars is 200mm, and the starting end of the transverse reinforcing bar is 80mm from the edge of the inner wall of the well wall.

[0011] As a further improvement of this utility model, the well body is a double-grate structure, and the height, length and width dimensions of the well wall are 750mm×1870mm×860mm; the number of longitudinal steel bars is 10, the spacing between the longitudinal steel bars is 200mm, and the starting end of the longitudinal steel bar is 35mm away from the edge of the inner wall of the well wall; the number of transverse steel bars is 4, the spacing between the transverse steel bars is 200mm, and the starting end of the transverse steel bar is 80mm away from the edge of the inner wall of the well wall.

[0012] As a further improvement of this utility model, the distance between the outer wall of the well body near the curbstone and the curbstone is 70±5mm.

[0013] The beneficial effects of this invention are as follows: This invention forms a three-dimensional anchoring system by pre-embedding a ring-shaped steel reinforcement strip around the manhole in a concrete capping layer, combined with layered compacted soil. This structure tightly connects the manhole body to the backfill soil, effectively dispersing the stress in the soil around the manhole, significantly reducing the risk of uneven settlement, and fundamentally solving the problems of tilting manholes and road collapse associated with traditional methods. The inner and outer anchoring sections of the steel reinforcement strip are deeply embedded in the soil layer and the capping layer, forming a rigid-flexible composite body between the manhole body and the backfill soil. When the soil undergoes slight displacement, the anchoring system achieves coordinated deformation through stress transfer, avoiding fracture or instability caused by independent stress on the manhole body, and significantly extending the service life of the road.
