Description

Technical Field

[0001] This utility model belongs to the field of urban infrastructure construction technology, specifically a prefabricated manhole body whose manhole cover angle can be adjusted according to the road slope. Background Technology

[0002] In urban road construction, manhole covers are an important part of the drainage system, and their design directly affects the efficiency of rainwater drainage and the smoothness of the road surface.

[0003] Traditional manhole cover designs often overlook changes in road slope, leading to unevenness at the joint between the manhole cover and the road surface on sloping roads. This not only affects the safety of vehicles and pedestrians but may also accelerate damage to the manhole cover and the surrounding road surface. Therefore, developing a manhole cover structure that can adjust the angle of the manhole cover according to the actual road slope is particularly important.

[0004] Based on this, a prefabricated manhole body with an adjustable manhole cover angle according to the road slope was designed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example 1, by Figures 1-3The present invention includes a base plate 1, a lower well cylinder 2, an intermediate well cylinder 3, a combined adjustable well cylinder 4, and a well seat 5. The lower well cylinder 2 is embedded in the upper end of the base plate 1, the intermediate well cylinder 3 is sleeved in the upper end of the lower well cylinder 2, the combined adjustable well cylinder 4 is sleeved in the upper end of the intermediate well cylinder 3, the well seat 5 is provided in the upper end of the combined adjustable well cylinder 4, and a well cover is embedded in the inside of the well seat 5.

[0023] The combined regulating well 4 includes a base 401, the upper end face of which is inclined, and an outer cylinder 402 is movably sleeved on the upper end of the base 401. The lower part of the inner wall of the outer cylinder 402 is provided with an internal thread 403. An inner cylinder 404 is embedded inside the outer cylinder 402. The lower part of the outer wall of the inner cylinder 404 is provided with an external thread 405. The external thread 405 and the internal thread 403 are threadedly engaged.

[0024] The inner cylinder 404 has a locking screw 406 threadedly connected to its lower inner side. One end of the locking screw 406 abuts against the inner wall of the outer cylinder 402. A locking nut 407 is fitted onto the outer thread of the locking screw 406.

[0025] The upper part of the outer cylinder 402 is threaded with a locking screw 408, one end of which abuts against the outer wall of the inner cylinder 404.

[0026] Working principle: Matching road slope:

[0027] First, based on the actual slope of the road, rotate the outer cylinder 402 to an appropriate angle. Since the upper surface of the base 401 is designed to be inclined, the rotation of the outer cylinder 402 can make its inclined surface match the road slope.

[0028] Adjusting the well height:

[0029] After matching the road slope, the height of the well body is adjusted by rotating the inner cylinder 404 and using the threaded engagement between the external thread 405 provided on the lower part of the outer wall of the inner cylinder 404 and the internal thread 403 provided on the lower part of the inner wall of the outer cylinder 402. This operation aims to ensure that the well seat 5 is kept horizontal or nearly horizontal with the ground.

[0030] Fixed inner and outer cylinders:

[0031] After adjusting the well height, the inner and outer cylinders are fixed using a locking mechanism. Specifically, first, the locking screw 406 is rotated so that one end abuts against the inner wall of the outer cylinder 402. Then, the locking nut 407 is tightened to fix the position of the locking screw 406. At the same time, the upper relative positions of the outer cylinder 402 and the inner cylinder 404 are fixed using the locking screw 408 to ensure that the inner cylinder 404 and the outer cylinder 402 will not loosen during subsequent use.

[0032] Keep the manhole cover stable

[0033] After the inner and outer cylinders are fixed, the manhole base 5 is kept horizontal or nearly horizontal with the ground. At this time, the manhole cover can be stably installed inside the manhole base 5 and will not loosen or be damaged due to uneven ground.

[0034] In summary, this prefabricated well body, through its innovative combined adjustable well cylinder 4 design, enables flexible adjustment of the well cover angle, effectively solving the applicability problem of traditional well covers on sloping roads. This design not only improves the safety and durability of urban drainage systems but also reduces maintenance costs caused by loose or damaged well covers.
