Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a well chamber backfilling and compacting tool used in a narrow space. Background Art

[0002] In municipal engineering, inspection wells and underground pipeline wells are common structures. In order to ensure the stability and safety of these structures, the backfill soil around the wells needs to be fully compacted.

[0003] A search revealed a Chinese patent application with publication number CN212104010U, which discloses a compaction tool for backfilling municipal pipeline inspection wells. The tool comprises a support frame and a rammer vertically positioned below the support frame. The support frame is a horizontally arranged rectangular frame, with an arc-shaped retaining plate at one end. The plate's curvature matches the curvature of the inspection well's outer wall, and several steel balls are positioned within the retaining plate. A handrail is provided at the other end of the support frame. The output end of the rammer is connected to a pressure plate, which is used to compact the soil. This utility model addresses the existing problems of ensuring the compaction and smoothness of the backfilled soil around the inspection well during backfill construction, as well as the potential for collision with the inspection well's outer wall during the compaction process, which can damage the inspection well. It features a simple structure and is easy to use.

[0004] Based on the above search and combined with existing technology findings;

[0005] The above-mentioned search patent adopts a traditional construction method, and the traditional compaction tools are large in size and difficult to enter the narrow well chamber for operation. The efficiency is low during the construction process and the construction quality cannot be guaranteed, so there are certain limitations. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a well chamber backfilling and compacting tool for narrow spaces, which can make operation more convenient and effective in narrow spaces and improve the accuracy of construction.

[0007] The technical solution to achieve the purpose of the utility model is: a well chamber backfilling and compacting tool for a narrow space, comprising a circular support steel plate, wherein the outer peripheral wall of the circular support steel plate is fixedly mounted with multiple sets of connecting frames, and a sensor is fixedly mounted at one end of each connecting frame.

[0008] Preferably, a retractable spring column is fixedly mounted on one end of the sensor, and a tamping plate is fixedly mounted on the tail end of the retractable spring column.

[0009] Compared with the prior art, the present invention has the following significant advantages:

[0010] First, the tamping head of the device of the utility model can be designed into a rectangular, circular or other shape to meet the needs of different well chamber structures, thereby improving the applicability and versatility of the equipment and expanding the scope of use.

[0011] Second, the sensors installed on the connecting frame of this utility model can monitor various parameters of the compaction process, such as pressure and depth, in real time, ensuring the safety and quality of the construction process. The feedback of sensor data allows operators to adjust the operation at any time to avoid over- or under-compaction, thus improving the accuracy of the construction.

[0012] The invention solves the problem that the existing traditional compacting tools are large in size, difficult to enter the narrow well chamber for operation, low in efficiency during the construction process and unable to ensure construction quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The utility model provides an improved well chamber backfilling and compacting tool for use in narrow spaces. The technical solution of the utility model is:

[0020] like Figure 1-Figure 2 As shown, a well chamber backfilling and compacting tool in a narrow space includes a circular support steel plate 1, and multiple groups of connecting frames 2 are fixedly installed on the outer peripheral wall of the circular support steel plate 1. A sensor 3 is fixedly installed at one end of each connecting frame 2. The length of the connecting frame 2 can be adjusted by a telescopic mechanism to adapt to well chambers of different depths and widths, thereby improving the applicability and versatility of the equipment.

[0021] Furthermore, a retractable spring column 4 is fixedly installed at one end of the sensor 3, and a tamping plate 5 is fixedly installed at the tail end of the retractable spring column 4. The sensor 3 installed on the connecting frame 2 can monitor various parameters in the tamping process, such as pressure, depth, etc., in real time to ensure the safety and quality of the construction process.

[0022] The specific working method is: the tamping plate 5 is made of high-strength metal and has a flat tamping surface. It can be designed into a rectangular, circular or other shape as needed to adapt to different well chamber structures; one end of the connecting frame 2 is connected to the tamping plate 5, and the other end is connected to the circular support steel plate 1, and the length can be adjusted; the sensor 3 is also a power device system, which is arranged inside the connecting rod and is used to drive the tamping plate 5 to move up and down. It is connected to the connecting frame 2 through a retractable spring column 4. The connecting frame 2 is welded to the circular support steel plate 1. The connecting frame 2 is equipped with a sensor 3. The length of the connecting frame 2 can be adjusted through a telescopic mechanism to adapt to well chambers of different depths and widths. The sensor 3 can be powered by a rechargeable battery so that it can work in a narrow space without power access.
