Description

Technical Field

[0001] This utility model relates to the field of manhole pipe connection technology, and in particular to a sealing template for the internal pipe end of a drainage manhole. Background Technology

[0002] In the construction of drainage pipe networks, the quality of the connection between inspection wells and pipes directly affects the sealing performance and service life of the drainage system. In existing technologies, pipes are usually directly inserted into the joints opened in the inspection wells, and then concrete is poured to fix them. Traditionally, temporary formwork spliced ​​on site is used for forming and support. These temporary formworks are usually made of materials such as wood boards and sheet metal. Gaps are prone to appear after these formworks are spliced, which leads to grout leakage during concrete pouring, affecting the sealing performance and structural strength of the joints. Moreover, the installation of temporary formwork requires repeated adjustments to the positioning, which is cumbersome, inefficient, and consumes a lot of manpower and time.

[0003] Therefore, it is necessary to provide a new type of molded template for sealing the internal pipe ends of drainage inspection wells to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a sealing template for the internal pipe end of a drainage inspection well.

[0005] The drainage inspection well internal pipe end sealing and shaping template provided by this utility model includes a U-shaped plate. An outer sealing module and an inner sealing module are respectively installed on the front and rear plates of the U-shaped plate. Two sets of the outer sealing module and the inner sealing module are provided. The two sets of the outer sealing module are symmetrically installed on the front plate of the U-shaped plate, and the two sets of the inner sealing module are symmetrically installed on the rear plate of the U-shaped plate. The outer sealing module includes an arc-shaped outer guide tube, which is fixedly installed on the front plate surface of the U-shaped plate. A sliding A plate is slidably connected to the arc-shaped outer guide tube. An arc-shaped outer template is fixedly installed at the bottom of the sliding A plate. A semi-circular outer cavity is opened on the arc-shaped outer template. A bottom edge coaxially arranged with the arc-shaped outer template is fixedly fitted at the bottom of the arc-shaped outer template. The inner sealing module includes an arc-shaped inner guide tube, which is fixedly installed on the rear plate surface of the U-shaped plate. A sliding B plate is slidably connected to the arc-shaped inner guide tube. An arc-shaped inner template is fixedly installed at the bottom of the sliding B plate, and a semi-circular inner cavity is opened on the arc-shaped inner template.

[0006] Preferably, a threaded locking screw A is inserted into the threaded through hole in the sliding plate A.

[0007] Preferably, the outer side walls of the two sets of arc-shaped outer templates are fixedly fitted with outer sealing edges, and when the two sets of arc-shaped outer templates are closed, the two semi-circular outer through cavities form a circular outer through hole structure.

[0008] Preferably, a threaded locking screw B is inserted into the threaded through hole on the sliding plate B.

[0009] Preferably, the outer walls of the two sets of arc-shaped inner templates are fixedly fitted with inner sealing edges, and when the two sets of arc-shaped inner templates are closed, the two semi-circular inner cavities form a circular inner through hole structure.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0016] Please see Figures 1 to 6 This utility model provides a drainage inspection well internal pipe end sealing and shaping template, which includes a U-shaped plate 1, an outer sealing module 2 and an inner sealing module 3.

[0017] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 The U-shaped plate 1 is provided with a threaded fastening screw 11. The front and rear plates of the U-shaped plate 1 are respectively equipped with an outer sealing module 2 and an inner sealing module 3. Both the outer sealing module 2 and the inner sealing module 3 are provided in two sets. The two sets of outer sealing module 2 are symmetrically installed on the front plate of the U-shaped plate 1, and the two sets of inner sealing module 3 are symmetrically installed on the rear plate of the U-shaped plate 1. The outer sealing module 2 includes an arc-shaped outer guide tube 21, which is fixedly installed on the front plate surface of the U-shaped plate 1. A sliding A plate 22 is slidably connected on the arc-shaped outer guide tube 21. An arc-shaped outer template 23 is fixedly installed at the bottom of the sliding A plate 22. A semi-circular outer cavity 23a is opened on the arc-shaped outer template 23. A threaded locking screw A221 is inserted into the threaded through hole opened on the sliding A plate 22. An outer sealing edge 231 is fixedly fitted on the outer side wall of the two sets of arc-shaped outer templates 23. A bottom edge 24 coaxially set with the arc-shaped outer template 23 is fixedly fitted at the bottom of the arc-shaped outer template 23. When the two sets of arc-shaped outer templates 23 are closed, the two semi-circular outer cavities 23a form a circular outer through hole structure. The inner sealing module 3 includes an arc-shaped inner guide tube 31, which is fixedly installed on the rear plate surface of the U-shaped plate 1. A sliding B plate 32 is slidably connected to the arc-shaped inner guide tube 31. An arc-shaped inner template 33 is fixedly installed at the bottom of the sliding B plate 32. A semi-circular inner cavity 33a is opened on the arc-shaped inner template 33. A threaded locking screw B321 is inserted into the threaded through hole opened on the sliding B plate 32. The outer walls of the two sets of arc-shaped inner templates 33 are fixedly fitted with inner sealing edges 331. When the two sets of arc-shaped inner templates 33 are closed, the two semi-circular inner cavities 33a form a circular inner through hole structure.

[0018] It should be noted that when installing this template, insert the U-shaped plate 1 onto the upper edge of the inspection well 100, then close the two arc-shaped outer templates 23 and the two arc-shaped inner templates 33, and simultaneously tighten the locking screws A221 and B321 to fix the arc-shaped outer templates 23 and the arc-shaped inner templates 33. Then slide the U-shaped plate 1 along the upper edge of the inspection well 100 until the circular outer through-hole structure and the circular inner through-hole structure correspond to the interface 100a on the inspection well 100. Then tighten the fastening screw 11 so that the outer wall of the U-shaped plate 1 abuts against the outer wall of the inspection well 100, and the fastening screw 11 abuts against the inner wall of the inspection well 100, thereby completing the installation of this template on the inspection well 100 (e.g., Figure 4 and Figure 5 (As shown).

[0019] It should also be noted that after the template is installed, the pipe 200 will pass through the circular outer through hole structure, the interface 100a and the circular inner through hole structure in sequence and then extend into the inspection well 100. At this point, the outer arc-shaped formwork 23, the outer sealing edge 231, the bottom edge 24, and the outer wall of the inspection well 100 form the outer pouring space of the pipe 200 and the inspection well 100, while the inner arc-shaped formwork 33, the inner sealing edge 331, the inner wall of the inspection well 100, and the bottom wall of the inspection well 100 form the inner pouring space of the pipe 200 and the inspection well 100 (as shown in the attached figure). Figure 6 As shown), concrete is then poured into the outer and inner pouring spaces respectively, and steel bars are inserted into the poured concrete for vibration and compaction. After the concrete has solidified, locking screws A221 and B321 are loosened, causing the two arc-shaped outer formwork 23 to slide and separate along the arc-shaped outer guide tube 21, and the two arc-shaped inner formwork 33 to slide and separate along the arc-shaped inner guide tube 31. Then, fastening screws 11 are loosened and the entire formwork structure is lifted, so that the entire formwork is removed from the pipe 200 and taken out of the inspection well 100.

[0020] It is worth noting that: in order to prevent the sliding A plate 22 from rotating on the arc-shaped outer conduit 21, an arc-shaped groove is provided on the arc-shaped outer conduit 21, and the sliding A plate 22 is fitted into the through hole on the arc-shaped outer conduit 21 with a protrusion that matches the arc-shaped groove. Therefore, the sliding A plate 22 is prevented from rotating on the arc-shaped outer conduit 21. The sliding B plate 32 is treated in the same way as the arc-shaped inner conduit 31.

[0021] In this embodiment: the gaps between the pipe 200 and the circular outer through hole structure and the circular inner through hole structure can be sealed with cloth strips to reduce the amount of concrete overflowing from the gaps (the operation is simple). Alternatively, annular grooves can be set on the inner walls of the semi-circular outer through hole 23a and the semi-circular inner through hole 33a, and an elastic sealing gasket matching the pipe diameter of the pipe 200 can be embedded in the grooves. The elastic sealing gasket is made of wear-resistant rubber material that does not easily stick to concrete. It can not only fit tightly to the outer wall of the pipe 200 to improve the sealing effect, but also avoid sticking to concrete. After disassembly, the interface surface is flatter, and the sealing gasket can be replaced individually to adapt to different pipe diameters.

[0022] In this application, the outer sealing module 2 slides along the arc-shaped outer guide tube 21 via the sliding plate A 22, and the inner sealing module 3 slides along the arc-shaped inner guide tube 31 via the sliding plate B 32. The circular outer through-hole structure formed by the two sets of arc-shaped outer templates 23 and the circular inner through-hole structure formed by the two sets of arc-shaped inner templates 33 can accurately match the interface 100a of the inspection well 100, exhibiting high versatility. The U-shaped plate 1 is quickly fixed to the upper edge of the inspection well 100 via the fastening screw 11, and the arc-shaped outer template 23 and the arc-shaped inner template 33 are quickly locked via locking screws A221 and B321, eliminating the need for complex splicing and enabling sliding... The adjustment achieves precise alignment with the interface 100a, significantly improving construction efficiency. The outer edge 231 and bottom edge 24 of the arc-shaped outer template 23, and the inner edge 331 of the arc-shaped inner template 33, can fit tightly with the inner and outer walls of the inspection well 100, effectively preventing grout leakage during concrete pouring. At the same time, the overall support structure of the template is stable and not easily displaced or deformed during pouring, ensuring the quality of the interface formation. After the concrete has solidified, the template can be separated and removed as a whole simply by loosening the locking screws A221, B321, and 11. The template is undamaged and can be reused multiple times, reducing construction costs.
