Description

Technical Field

[0001] This utility model relates to the field of pipe curtain installation technology, specifically a pipe curtain connection and fastening device. Background Technology

[0002] In tunnel engineering, underground pipelines, water conservancy projects, and various fields requiring continuous pipe jacking structures, the installation and connection of pipe jackings is a core component. Pipe jacking structures are commonly used to withstand external soil and water pressure, transfer internal loads, or serve as foundation supports for other structures. Therefore, ensuring the reliability and sealing of the connections between pipe sections and the overall stability of the structure is of paramount importance.

[0003] There are various existing pipe curtain connection methods, including flange connection and sleeve connection. However, flange connection usually requires a large installation space, the cost of flange and bolt is high, and the sealing treatment may be more complicated under high water pressure or special geological conditions. Sleeve connection is relatively flexible, but the structural design and manufacturing precision of the sleeve itself are required, and the sealing treatment at the connection also needs special attention.

[0004] Therefore, a pipe curtain connection and fastening device is needed to improve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a pipe curtain connection and fastening device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pipe curtain connection fastening device includes several steel pipes, and several connecting fasteners are provided on the outer side of each steel pipe. The connecting fasteners include a mating part a and a mating part b. The mating parts a and b on the adjacent steel pipes on both sides cooperate and lock together, and the steel pipe in the middle is fixedly connected to both sides of the mating part a.

[0008] As a preferred embodiment of this utility model, the docking part a includes a set of interlocking joints a with opposite openings; the docking part b includes a set of interlocking joints b with opposite openings.

[0009] As a preferred embodiment of this utility model, the adjacent interlocking connectors a and b are engaged and locked together.

[0010] As a preferred embodiment of this utility model, a plurality of reinforcing ribs a are fixedly connected at equal intervals between the outer side of the interlocking joint a and the steel pipe, and reinforcing ribs b are fixedly connected between adjacent interlocking joints b.

[0011] As a preferred embodiment of this utility model, the reinforcing rib a is inclined, and both ends of the reinforcing rib a are fixedly connected to the outer sides of the steel pipe and the interlocking joint a, respectively.

[0012] In a preferred embodiment of this utility model, the reinforcing rib b is vertically arranged.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Compared with flange connections, this utility model avoids large flanges and numerous bolts, reducing the space requirements for installation. By setting reinforcing ribs a and b, the structural strength and rigidity of the connecting fasteners and their interlocking joints are enhanced, improving the overall load-bearing capacity and stability of the connection. The locking and snapping design between interlocking joints a and b enables quick and reliable docking and fastening between adjacent steel pipes. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] To facilitate understanding of this utility model, a more comprehensive description of it will be provided below with reference to relevant embodiments. Several embodiments of this utility model are given. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0022] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
