Description

Technical Field

[0001] This utility model belongs to the field of prefabricated well pipe connection technology, and in particular relates to a prefabricated well wall embedded pipe connector. Background Technology

[0002] In the construction of precast wells, the reliable connection between the well wall and the external pipeline is a key link to ensure the system's sealing and structural integrity. Traditional methods often involve on-site drilling followed by welding or mortar fixing of embedded parts, which suffers from low construction efficiency, high precision requirements, and high labor intensity. Alignment between embedded parts and pipelines is difficult, often requiring repeated adjustments, which can easily damage the concrete structure of the well wall. The sealing performance of the connection is highly dependent on the operator's skill level, making it difficult to guarantee quality stability and prone to leakage during use. In addition, existing embedded connection structures lack adaptability and adjustment capabilities, making it difficult to compensate for construction errors or displacement caused by thermal expansion and contraction of pipelines, increasing the cost and difficulty of later maintenance.

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1 Please see Figures 1 to 3This utility model is a prefabricated manhole wall embedded pipe connector, including a connecting sleeve 1 and a cover 2. By fixing a semi-circular tubular receiving pipe 101 with an upward opening on one end face of the connecting sleeve 1, the connecting sleeve is connected to the manhole wall of the prefabricated manhole. One end of the pipe to be connected is placed inside the receiving pipe 101, and the cover 2 is placed on the receiving pipe 101, thereby realizing the rapid connection between the pipe and the prefabricated manhole, eliminating the need to move the pipe laterally. By fixing receiving ears 101a on the outer walls of the upper two sides of the receiving pipe 101 and cover ears 201 on the side walls of the lower two sides of the cover 2, the two connecting covers 102 are fixedly sleeved on the outer sides of the receiving ears 101a and cover ears 201, so that the cover 2 is connected to the receiving pipe 101.

[0023] Specifically, a receiving tube 101 is fixedly provided on one end face of the connecting sleeve 1. The receiving tube 101 is a semi-circular tubular structure with the opening facing upward. The cover 2 is a semi-circular tubular structure with the opening facing downward. The cover 2 covers the upper end face of the receiving tube 101. Receiving ears 101a are fixedly provided on the outer walls of the upper two sides of the receiving tube 101. Cover ears 201 are fixedly provided on the outer walls of the lower two sides of the cover 2. The cover ears 201 on both sides cover the upper ends of the receiving ears 101a on both sides. Connecting covers 102 are provided on both sides of the receiving tube 101. The connecting covers 102 are U-shaped structures with the opening facing the axis of the receiving tube 101. The connecting covers 102 on both sides are respectively sleeved on the outside of the receiving ears 101a and the cover ears 201 on both sides.

[0024] Furthermore, the lower end face of the receiving ear 101a and the upper end face of the cover ear 201 are respectively provided with sliding grooves parallel to the pipe axis. The inner sides of the upper and lower end horizontal plates of the connecting cover 102 are respectively fixed with sliding tenons 102a. The sliding tenons 102a at the upper and lower ends of the connecting cover 102 are slidably sleeved in the sliding grooves on the lower end face of the receiving ear 101a and the upper end face of the cover ear 201, respectively, to prevent the connecting cover 102 from falling off after it covers the outside of the receiving ear 101a and the cover ear 201. Furthermore, the inner wall of the receiving pipe 101 is fixedly fitted with an upward-opening rubber ring 103, and the inner wall of the cover 2 is fixedly fitted with another downward-opening rubber ring 103, which serves to seal the pipe.

[0025] Furthermore, a vertical sliding groove 101b is provided at the bottom of the inner wall of the receiving pipe 101. A rubber ring support 101b-1 is slidably sleeved in the vertical sliding groove 101b. The upper end face of the rubber ring support 101b-1 is attached to the lower side wall of the rubber ring 103 inside the receiving pipe 101. A set of buffer springs 101b-2 is provided in the vertical sliding groove 101b. The two ends of the buffer springs 101b-2 are respectively fixedly connected to the lower end face of the rubber ring support 101b-1 and the bottom end face of the vertical sliding groove 101b. After connecting the connecting sleeve 1 to the side wall of the precast well, the pipe is lowered vertically so that one end of the pipe is placed into the receiving pipe 101. During the lowering process, the weight of the pipe presses down on the rubber ring support 101b-1, causing the rubber ring support 101b-1 to squeeze the buffer spring 101b-2 downwards, so that the buffer spring 101b-2 absorbs the impact and prevents the pipe from cracking the receiving pipe 101.

[0026] The operation process in this embodiment is as follows: Connect one end of the connecting sleeve 1 to the wall of the precast well, and lower the pipe vertically so that one end of the pipe is placed inside the receiving pipe 101. During the lowering process, the weight of the pipe presses down on the rubber ring support 101b-1, causing the rubber ring support 101b-1 to squeeze the buffer spring 101b-2 downwards, so that the buffer spring 101b-2 absorbs the impact and prevents the pipe from cracking the receiving pipe 101. After the pipe is placed inside the receiving pipe 101, cover the top of the receiving pipe 101 with the cover 2, and slide the two connecting covers 102 from one end onto the outside of the two receiving ears 101a and the cover ears 201 respectively.

[0027] Example 2 Please see Figures 1 to 5 Based on Example 1, a pipe-attached side plate 104 is fixedly provided on the end face of the docking sleeve 1 away from the receiving pipe 101. When installing the docking sleeve 1, the pipe-attached side plate 104 is attached to the outer wall of the precast well, so that one end of the docking sleeve 1 is tightly attached to the precast well.

[0028] Specifically, the side of the tube-attached side plate 104 away from the docking sleeve 1 is a vertically concave arc surface.

[0029] Furthermore, a docking cone 104a is fixed on the side of the pipe-attached side plate 104 away from the docking sleeve 1. The outer wall of the docking cone 104a gradually narrows towards the end away from the pipe-attached side plate 104. The docking cone 104a is inserted into the through hole of the prefabricated well side wall, so that the docking sleeve 1 is connected to the prefabricated well.

[0030] Furthermore, a retaining clamp 105 is provided on the lower end face of the pipe-attached side plate 104, and a tenon 104b is fixed on the lower end face of the pipe-attached side plate 104. Two mortises 105a are arranged in a circumferential array on the upper end face of the retaining clamp 105. The tenon 104b is engaged in the mortises 105a to prevent the pipe-attached side plate 104 and the connecting sleeve 1 from moving laterally.

[0031] The operation process in this embodiment is as follows: The clamp 105 is fitted onto the bottom of the outer side of the precast well. The pipe-attached side plate 104 on one side of the docking sleeve 1 is attached to the outer side wall of the precast well. The docking cone 104a is inserted into the through hole in the side wall of the precast well, so that the tenon 104b is fitted into the mortise 105a, thus completing the connection between the docking sleeve 1 and the precast well.
