Description

Technical Field

[0001] The utility model relates to the technical field of inspection well construction, in particular to a telescopic chute template suitable for the inspection well. Background Art

[0002] At present, in order to ensure a perfect transition of the drainage structure at the junction of the two pipes and to ensure smooth drainage, the urban drainage system usually requires a chute to be installed at the bottom of the inspection well. Among them, there are two existing methods for the construction of inspection well chutes, one is to use brickwork for masonry, and the other is to use a fixed formwork for installation and then pouring concrete; in actual construction, no matter which of the above methods is used, it takes at least 3-4 hours to complete the masonry or pouring of the inspection well chute, resulting in low construction efficiency due to the long construction time. The specific reasons for the long time consumption are as follows. Take the pouring method as an example: the traditional chute pouring mode requires breaking the pipe first, and then pouring the inspection well. After the inspection well is stable, the chute formwork is supported, and then the chute is poured. This method is very time-consuming.

[0003] In addition to the above-mentioned defects, the existing casting templates also have the following drawbacks: the traditional casting structure cannot be formed in one go. When faced with different sizes of inspection wells that have already been laid, the size of the chute template cannot be flexibly adjusted, resulting in an unstable cast structure. Low versatility: In actual construction, the sizes of different types of inspection well chutes vary. Usually, a set of wooden molds can only process one type of chute. For different types of chute, the wooden mold needs to be customized, that is, multiple sets of molds need to be made to form different types of chute, which has low versatility.

[0004] Based on this, those skilled in the art are in urgent need of improving the above-mentioned prior art to overcome the above-mentioned defects. Utility Model Content

[0035] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] Example 1

[0037] Traditional inspection well chutes mostly use an integrally formed U-shaped trough as a chute template, but the size of this chute template cannot be adjusted. For this reason, this embodiment designs a chute template that can change the curvature and adjust the length.

[0038] Specifically:

[0039] like Figure 4-6 The embodiment shown discloses a telescopic chute template suitable for an inspection well, comprising: two arc-shaped chute forming templates 1, a retractable central axis 2 and a limiting device 3;

[0040] Two chute forming templates 1 are socketed;

[0041] The two ends of the retractable central shaft 2 are pipe support structures for fixing the drainage pipes at both ends of the drainage structure;

[0042] A three-way fixing structure is provided on the middle section of the retractable central shaft 2;

[0043] Each chute shaping template 1 is provided with a sliding hole adapted to the three-way fixing structure;

[0044] The vertical legs of the three-way fixing structure pass through the sliding holes and are adapted to the limiting device 3 .

[0045] In practical applications, the three-way fixed structure can be set up with multiple three-way fixed structures. The more the number, the more stable the structure. Figure 1 As shown, the number of three-way fixed structures in the figure is 3.

[0046] In this embodiment, the retractable central shaft 2 includes: a retractable connecting shaft, a pipe support structure and a three-way fixing structure;

[0047] The pipeline supporting structure, the multiple three-way fixing structures and the pipeline supporting structure are connected in sequence through a retractable connecting shaft.

[0048] In this embodiment, the pipeline support structure is a cross structure.

[0049] In this embodiment, the three-way fixing structure is composed of a vertical support leg and two horizontal support legs; the two horizontal support legs are located on the same axis, and the vertical support leg and the two horizontal support legs are fixedly connected to the retractable connecting shaft;

[0050] The vertical legs, the horizontal legs and the retractable connecting shafts are perpendicular to each other.

[0051] In this embodiment, the pipe support structure and the legs in the three-way fixing structure both adopt a retractable structure.

[0052] In this embodiment, the retractable structure adopted by the supporting legs is specifically a bolt structure.

[0053] The limiting device 3 adopts a nut. It should be noted that in the prior art, during construction, it is generally necessary to at least break the pipeline first, and then cast the inspection well. After the inspection well is stable, the chute formwork is carried out, and then the chute is cast. This method wastes a lot of construction time, and the cast structure is also unstable and cannot be formed in one go. If there are inspection wells of different sizes that have already been laid, it is impossible to flexibly adjust the size of the chute template. To this end, in this embodiment, the vertical support legs and the limiting device 3 of the three-way fixed structure are used to form the connecting parts of the two chute forming templates 1. The vertical support legs slide in the sliding holes of the chute forming templates. At the same time, since the three-way fixed structure, the retractable connecting shaft and the pipeline support structure are designed as an integrated retractable center shaft, the stability of the overall device after connection is compared to the example. Figure 3 The existing spliced-type chute shown is better;

[0054] At the same time, based on the use of bolt structure, compared with the existing Figure 3 The spliced ​​chute shown is easier to disassemble.

[0055] The length of the chute forming template used in this embodiment is 70 cm, and 70 cm ≤ the overall length of the device ≤ 140 cm.

[0056] In addition, in this embodiment, the horizontal support leg of the three-way fixed structure is used to change the curvature from the inside to the outside, and the application of the outward force is compared with the Figure 2 The method of using the spring to act inward to change the curvature is more stable and reliable; and in this embodiment, there is also the stabilization assistance of the vertical support feet, which makes the stability when adjusting the curvature better.

[0057] Actual construction process:

[0058] Step 1: Place the device of this embodiment in the inspection well where the inspection well trough is to be cast;

[0059] Step 2: Adjust the overall length of the chute template by pulling out the retractable central axis 2, and place both ends of the chute template in the upstream and downstream pipe openings of the inspection well;

[0060] Step 3: Adjust the bolt lengths of the support legs of the pipe support structure at both ends of the chute template so that the chute template is fixed as a whole at the upstream and downstream pipe openings;

[0061] Step 4: Adjust the bolt length of the horizontal support leg of the three-way fixed structure to support each chute forming template 1;

[0062] Step five: pour concrete at the preset location, inspect and repair it after pouring, and complete the construction of the inspection well chute.

[0063] In actual implementation, only slurry will seep out of the sliding hole, and no aggregate will seep out, so it will not affect the casting effect and can be ignored. In addition, the height difference at the connection between the two chute forming templates 1 will not affect the overall casting effect in actual construction because the thickness of the chute forming templates 1 themselves is small.

[0064] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
