Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a ventilation pipe fixing device for pipe jacking construction. Background Technology

[0002] Pipe jacking is a trenchless pipeline laying technology used in municipal construction. During long-distance (generally greater than 200m) pipe jacking, ventilation ducts need to be installed inside the pipeline for ventilation to ensure the safety of workers entering the pipeline. Normally, ventilation ducts are placed directly on the lower part of the inner wall of the pipeline, and simple fixing ensures installation stability. However, in situations where space is limited in the lower part of the pipeline, such as in slurry balance pipe jacking, where components like sludge discharge pipes need to be installed, it's difficult to place ventilation ducts there; furthermore, placing ventilation ducts at the bottom also affects the working space for workers. Therefore, it is necessary to place the ventilation ducts at the top of the pipeline. However, due to the lack of installation points at the top of the pipeline, installation is difficult. Currently, the common method is to drill holes in the top of the inner wall of the pipeline and then install expansion bolts to provide installation points for the ventilation ducts. However, in actual construction, it has been found that this method requires multiple people to work together to complete the connection and installation of the ventilation ducts, has high requirements for drilling accuracy, and has low construction efficiency; moreover, drilling can damage the pipeline itself.

[0003] Therefore, it is necessary to develop and design a ventilation duct fixing device for pipe jacking construction. It should be able to meet the stable installation requirements when the installation space at the bottom of the pipe is limited and the ventilation duct is placed on the top of the inner wall of the pipe, while also improving the construction efficiency of the ventilation duct. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a ventilation pipe fixing device for pipe jacking construction, which can help meet the stable installation requirements when the ventilation pipe is arranged on the top of the inner wall of the pipe due to limited installation space at the bottom of the pipe, and at the same time help improve the construction efficiency of the ventilation pipe.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a ventilation pipe fixing device for pipe jacking construction, comprising at least two sets of support mechanisms disposed inside the pipe for supporting the ventilation pipe; the support mechanism includes a support ring conformally disposed to the inner wall of the pipe and having an opening at the top, and a clamping component disposed at the opening of the support ring for clamping the ventilation pipe.

[0006] Furthermore, the snap-fit ​​assembly includes a first tube clamp and a second tube clamp respectively fixed at both ends of the circumferential direction of the opening of the support ring.

[0007] Furthermore, the two circumferential ends of the support ring opening are respectively bent downward to form a first ear and a second ear, the first tube clamp is fixed on the first ear, and the second tube clamp is fixed on the second ear.

[0008] Furthermore, the first tube clamp is adjustable in the left and right position relative to the first ear, and the second tube clamp is adjustable in the left and right position relative to the second ear.

[0009] Furthermore, a first adjusting screw is fixed on the first pipe clamp, and the first adjusting screw is fixed to the first lug by a first locking nut; a second adjusting screw is fixed on the second pipe clamp, and the second adjusting screw is fixed to the second lug by a second locking nut.

[0010] Furthermore, both the first and second pipe clamps are L-shaped support plates, and the two L-shaped support plates are arranged opposite each other to form a U-shaped clamp structure with the opening facing upward.

[0011] Furthermore, a first elastic pad is fixed to the contact surface between the first pipe clamp and the ventilation pipe, and a second elastic pad is fixed to the contact surface between the second pipe clamp and the ventilation pipe.

[0012] Furthermore, both the first elastic pad and the first elastic pad are rubber pads.

[0013] Furthermore, the support ring is a ring-shaped plate structure.

[0014] The beneficial effects of this utility model are as follows:

[0015] This utility model provides a ventilation duct fixing device for pipe jacking construction, which can help meet the stable installation requirements when the installation space at the bottom of the pipe is limited and the ventilation duct is placed on the top of the inner wall of the pipe, while also improving the construction efficiency of the ventilation duct. Specifically, the ventilation duct can be stably supported by at least two sets of support mechanisms; due to the use of a top-opening support ring structure, the manufacturing precision of the support ring does not need to be too high, and it can be easily assembled into the pipe, ensuring the installation efficiency of the support ring; since the support ring can be attached to the inner wall of the pipe, it will not affect the arrangement and installation of other components at the bottom of the pipe; in addition, the support ring provides an installation point for the snap-fit ​​assembly, eliminating the need to drill holes in the pipe and preventing damage to the pipe body.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figure 1-2 This embodiment discloses a ventilation pipe fixing device for pipe jacking construction, including at least two sets of support mechanisms disposed within the pipe 1 to support the ventilation pipe 2. Each support mechanism includes a support ring 3 conformally fitted to the inner wall of the pipe 1 and open at the top, and a clamping assembly disposed at the opening of the support ring 3 to clamp the ventilation pipe 2. It is understood that the support mechanisms are arranged along the length of the pipe 1, and by setting at least two sets of support mechanisms, stable support can be formed at both ends of the ventilation pipe 2. In this embodiment, two sets of support mechanisms are provided, respectively positioned at the ends of the pipe section near the open ends. The purpose of using a support ring 3 with an open top is to ensure that the support ring 3 has a certain elastic contraction function, thereby reducing the installation difficulty of the support ring 3 within the pipe 1 and ensuring construction efficiency. The support ring 3 can be made by bending steel plates or reinforcing bars. The support ring 3 fits against the inner wall of the pipe 1 and will not affect the arrangement and installation of other components in the lower part of the pipe 1; at the same time, the support ring 3 provides an installation point for the clamping assembly, eliminating the need for drilling holes in the pipe 1, resulting in high construction efficiency and no damage to the pipe body. By employing snap-fit ​​components, such as pipe clamps, the ventilation duct 2 is secured, making installation convenient and ensuring its stability. The ventilation duct fixing device provided above for pipe jacking construction effectively meets the stable installation requirements when the lower installation space of pipe 1 is limited, and the ventilation duct 2 is placed on the top of the inner wall of pipe 1. It also improves the construction efficiency of the ventilation duct 2.

[0022] In this embodiment, the snap-fit ​​assembly includes a first pipe clamp 4 and a second pipe clamp 5, which are respectively fixed at both ends of the circumferential direction at the opening of the support ring 3. By using the first pipe clamp 4 and the second pipe clamp 5 to enclose and fix the ventilation pipe 2, the installation stability of the ventilation pipe 2 is well improved; at the same time, the structure is simple and the installation is convenient.

[0023] In this embodiment, the two circumferential ends of the opening of the support ring 3 are respectively bent downward to form a first lug 301 and a second lug 302. The first pipe clamp 4 is fixed on the first lug 301, and the second pipe clamp 5 is fixed on the second lug 302. By forming the first lug 301 and the second lug 302, a stable mounting position can be easily provided for the first pipe clamp 4 and the second pipe clamp 5, ensuring structural reliability. At the same time, it is beneficial to the lightweight design of the support ring 3, which helps to reduce material usage and processing difficulty, thereby saving manufacturing costs.

[0024] In this embodiment, the first pipe clamp 4 is adjustable in the left and right position relative to the first lug 301, and the second pipe clamp 5 is adjustable in the left and right position relative to the second lug 302. It can be understood that "left and right" here corresponds to the lateral direction of pipe 1 on the horizontal plane. During pipe jacking construction, when adjacent pipes 1 are joined, it cannot be guaranteed that the ventilation pipes 2 in adjacent pipes 1 will be perfectly aligned; there may be a small positional error, which will affect the joining efficiency. Therefore, by setting the first pipe clamp 4 and the second pipe clamp 5 to be adjustable in the left and right positions, the position of the ventilation pipe 2 can be easily adjusted, thereby facilitating the joining of the ventilation pipes 2 and further improving construction efficiency.

[0025] In this embodiment, a first adjusting screw 401 is fixedly mounted on the first pipe clamp 4, and the first adjusting screw 401 is fixedly mounted on the first support lug 301 by a first locking nut 402; a second adjusting screw 501 is fixedly mounted on the second pipe clamp 5, and the second adjusting screw 501 is fixedly mounted on the second support lug 302 by a second locking nut 502. Specifically, the first pipe clamp 4 is welded to the first adjusting screw 401, and the second adjusting screw 501 is welded to the second pipe clamp 5; the first support lug 301 and the second support lug 302 are respectively provided with strip-shaped holes arranged vertically; the first adjusting screw 401 and the second adjusting screw 501 are respectively inserted into the corresponding strip-shaped holes. There are two sets of first locking nuts 402, used to tighten the first adjusting screw 401. There are two sets of second locking nuts 502, used to tighten the second adjusting screw 402. The adjustment mechanism in this design is simple in structure, which facilitates the position adjustment of the first pipe clamp 4 and the second pipe clamp 5. At the same time, it has good locking reliability and is easy to adjust.

[0026] In this embodiment, both the first pipe clamp 4 and the second pipe clamp 5 are L-shaped support plates, which are arranged opposite each other to form an upward-facing U-shaped clamp structure. Specifically, the L-shaped support plates are made of steel plate. In use, the horizontal sections of the two L-shaped support plates abut against each other to form a U-shaped clamp structure, and the ventilation pipe 2 is clamped in the U-shaped opening. The first pipe clamp 4 and the second pipe clamp 5 in this structural design have a simple structure, reliable support, and are easy to process.

[0027] In this embodiment, a first elastic pad 6 is fixedly provided on the contact surface between the first pipe clamp 4 and the ventilation pipe 2, and a second elastic pad 7 is fixedly provided on the contact surface between the second pipe clamp 5 and the ventilation pipe 2. Specifically, the first elastic pad 6 is adhered to the first pipe clamp 4, and the second elastic pad 7 is adhered to the second pipe clamp 5. By setting the first elastic pad 6 and the second elastic pad 7 for buffer compression, manufacturing errors can be compensated during the adjustment process, which can further improve the clamping stability of the ventilation pipe 2. In addition, it can prevent damage to the body of the ventilation pipe 2.

[0028] In this embodiment, both the first elastic pad 6 and the first elastic pad 7 are rubber pads, which have good durability and stability.

[0029] In this embodiment, the support ring 3 is an annular plate structure. It is understood that this annular plate is not closed and has an opening. The annular plate structure provides good support stability and is simple to manufacture.

[0030] Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
