Description

Technical Field

[0001] This utility model belongs to the field of building construction equipment technology, specifically relating to a prefabricated water collection well cover and its adjustable support device, and in particular a prefabricated water collection well cover and its adjustable support device that can quickly adjust the position of the pipeline without secondary processing. Background Technology

[0002] In traditional building construction, fixed, non-perforated pipe holes are often used for basement sump covers. This method has several drawbacks. First, it requires secondary processing of the cover to allow pipes to pass through, which is not only cumbersome and inefficient but also affects the cover's aesthetics and poses a risk to its overall integrity. Second, traditional precast covers often suffer from poor quality due to secondary processing during construction. Finally, while there have been methods similar to prefabricated sump covers, they often cannot accommodate misalignment errors caused by pipe installation or are limited to pipes in fixed positions, failing to meet the requirements of both types of installation. Furthermore, the cover material often requires on-site secondary processing, resulting in resource waste.

[0003] Currently, the precast manhole covers commonly used in engineering projects not only have limited adaptability, poor installation accuracy and sealing effect, and are difficult to adjust later, but also require on-site processing and cutting of pipe holes according to the pipeline, which is difficult to operate, has poor forming effect, affects aesthetics, and on-site processing and cutting increases time and labor costs. Installation can only be carried out after the ground is poured, which affects the construction period. Precast manhole covers also require temporary protection on the construction site, which poses a significant safety hazard.

[0004] Therefore, there is an urgent need for a type of water collection well cover that requires no secondary processing, allows for quick adjustment of pipe positions, and is easy to install. Summary of the Invention

[0011] As a preferred embodiment of this application, the angle steel adjusting assembly further includes a fastening nut, which forms a threaded fastening pair with the threaded section of the positioning bolt, for achieving a locking fit between the positioning bolt and the strip-shaped adjusting hole.

[0012] As a preferred embodiment of this application, the angle steel is L-shaped.

[0013] As a preferred embodiment of this application, both the grating cover and the connecting plate are rectangular flat plate components, and the two are joined together by their long sides to form a continuous bearing surface that covers the inspection port.

[0014] As a preferred embodiment of this application, the splicing edge of the grille cover is provided with a flange structure, which forms an interlocking fit with the groove opened on the splicing edge of the connecting plate.

[0015] As a preferred embodiment of this application, both the grating cover and the connecting plate are rectangular flat plate components. The connecting plate is installed on the long side area of ​​the grating cover in a partially overlapping manner, covering a portion of the grating cover to form a stacked load-bearing structure with a stepped load-bearing interface.

[0016] This application also provides a prefabricated water collection well cover, including an adjustable support device for the prefabricated water collection well cover.

[0017] The beneficial effects of this utility model are: 1. It can combine factory processing and on-site pre-reservation, eliminating the need for secondary processing such as on-site cutting. The components are of high quality, easy and quick to install, and aesthetically pleasing. 2. Pre-drilled holes on the connecting plate allow the grid cover to be pre-processed.

The water collection well cover plate 2 includes a connecting plate 21 with a pipe sleeve 23 and a grid cover plate 22 installed on the connecting plate 21. The connecting plate 21 is adjustablely assembled with the inspection port of the precast concrete base 1 through a position adjustment mechanism 4.

[0034] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the position adjustment mechanism 4 includes strip-shaped adjustment holes 41 opened at both ends of the connecting plate 21 and angle steel adjustment components 42 pre-embedded in the top of the precast concrete base 1. The angle steel adjustment components 42 are provided with positioning bolts 422 that cooperate with the strip-shaped adjustment holes 41. The planar position adjustment of the water collection well cover plate 2 is realized by the cooperation between the positioning bolts 422 on the angle steel adjustment components 42 and the strip-shaped adjustment holes 41.

[0035] In some embodiments of this application, the access port is rectangular.

[0036] like Figure 1 and Figure 6 As shown, the number of strip-shaped adjustment holes 41 is an even array of multiple groups, with two strip-shaped adjustment holes 41 in each group distributed symmetrically on both sides of the connecting plate 21, and the strip-shaped adjustment holes 41 are along the length direction of the inspection port.

[0037] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the angle steel adjusting assembly 42 includes: Two angle steels 421 are symmetrically embedded on both sides of the long side of the inspection port of the precast concrete base 1; and Several sets of positioning bolts 422 are vertically fixed on the angle steel 421, with the threaded section extending upward and passing through the corresponding strip-shaped adjustment hole 41.

[0038] In some embodiments of this application, the head of the positioning bolt 422 is fixed to the angle steel 421 by welding. When it is necessary to adjust the position of the pipe sleeve 23, the locking position of the positioning bolt 422 in the strip-shaped adjustment hole 41 is adjusted. Specifically, the connecting plate is moved left and right to adjust the position of the pipe sleeve 23, so that the pipe 3 passes through the pipe sleeve 23. After the position is fixed, the positioning bolt 422 is used to connect and fix it through the strip-shaped adjustment hole 41, thereby achieving the function of adjusting the pipe sleeve 23 and the pipe. After the pipe position is fixed, the custom grating cover plate is installed, and concrete is poured on the sliding steel plate.

[0039] In some embodiments of this application, the angle steel adjusting assembly 42 further includes a fastening nut, which forms a threaded fastening pair with the threaded section of the positioning bolt 422, for realizing the locking engagement between the positioning bolt 422 and the strip-shaped adjusting hole 41.

[0044] This application also provides a prefabricated water collection well cover, including the adjustable support device.

[0045] Specifically, in actual implementation, after the pipeline position is fixed, a custom-made grating cover is installed, and concrete is poured onto the sliding steel plate. Taking a 1000*1000 inspection port as an example, the connecting plate is a steel plate with dimensions of 950mm (length) × 300mm (width), the grating cover is 1000mm*700mm, the angle iron is 100mm*100mm, the pipeline diameter is 250mm, the grating cover thickness is 10mm, the pipe sleeve has a cross-sectional diameter of 260mm and a height of 10mm, the strip adjustment hole length is 50mm, and the positioning bolt is ¢10mm.

[0046] This application discloses an adjustable support device for prefabricated water collection well covers. Angle iron and a precast concrete base are connected, and positioning bolts are welded to the angle iron. The connecting plate moves left and right to adjust the position of the pipe sleeve, allowing the pipe to pass through the sleeve. After the position is fixed, positioning bolts are passed through strip-shaped adjustment holes and secured with fastening nuts. After the pipe position is fixed, a custom-made grating cover is installed, and concrete is poured onto the connecting plate. This application combines factory-standardized processing with on-site pre-installation, utilizes readily available materials, has a simple structural system, high construction efficiency, is adaptable to different pipe diameters, and consumes few resources. It aligns with the green, environmentally friendly, and energy-saving concepts in the construction engineering field, possessing significant economic and safety advantages, and is worthy of widespread application in projects.

Furthermore, various modifications listed herein, as well as variations in the methods and compositions of the utility model, will be apparent to those skilled in the art without departing from the scope and spirit of this utility model. Although this utility model has been specifically described in conjunction with various specific preferred embodiments, it should be understood that this utility model should not be limited to these specific embodiments.
