Description

Technical area

The present utility model relates to bridge construction, and in particular to a connection system between underwater tubular steel piles.

State of the art

With the demands on development strategies and the intensification of the transport networks in China, more and more bridges are being built across bodies of water. Support pillars are transport corridors that ensure bridge construction over water and are among the large temporary facilities during bridge construction. The tubular steel piles of a steel frame in a deep water area have long underwater booms and suffer from poor stability. To improve the stability of a tubular steel pile, there are two common methods: one is to reduce the free length of a tubular steel pile in the water by installing a side connection system, and the other is to increase the diameter of the tubular steel pile.

The underwater side connection system is attached by underwater welding. However, the underwater welding process is complicated, expensive equipment is required, and the quality of the weld cannot be guaranteed. It is therefore difficult to promote and use this method. At present, tubular steel piles of large diameters are generally used to improve the stability of the tubular steel piles, thereby increasing the amount of material. A large tonnage hoist must be used for lifting, which is not good for controlling construction costs.

Description of the invention

The subject of the present utility model is that the present utility model provides a connection system between underwater tubular steel piles in view of the technical problem of the prior art, namely that when welding the lateral connection system between underwater tubular steel piles in the steel trestles, the underwater welding process is complicated and expensive Devices are required and that the welding quality cannot be guaranteed. It is therefore difficult to promote and use this method. The assembly of a side joint system by the method does not require underwater welding and is very applicable, which can effectively reduce the free length of a tubular steel pile and improve its stability, thereby achieving the goal of effective control of construction costs.

• Ein Verbindungssystem zwischen Unterwasser-Stahlrohrpfählen, dadurch gekennzeichnet, dass es mindestens zwei Muffen und mindestens eine Begrenzungsvorrichtung umfasst.

The following technical solutions are used in the present utility model to achieve the above-mentioned goal:

• A connection system between underwater tubular steel piles, characterized in that it comprises at least two sleeves and at least one limiting device.

The limiting device is firmly connected to a tubular steel pile.

The sleeves are hollow construction parts. Two adjacent sleeves are arranged opposite one another. A rod part of the connection system is arranged between the outer walls of the adjacent sleeves. The two ends of the rod part of the connection system are each connected to the outer walls of the two adjacent sleeves. The socket is installed outside of a tubular steel pile and the socket is clamped in place after the bottom of the socket is butted against the limiter.

The connection system between underwater tubular steel piles provided in the present utility model comprises at least two sleeves and at least one limiting device. In use, several sleeves are arranged on a tubular steel pile. A rod part of the connection system is arranged between adjacent sleeves. A tubular steel pile is firmly connected to a boundary device. After the tubular steel pile has been brought into a certain position, a sleeve is attached outside the tubular steel pile and moved into the position of a limiting device, whereby the sleeve is firmly clamped and fixed. The connection system is simple and easy to assemble. It does not need to be welded underwater and is widely applicable, whereby the free length of a tubular steel pile can be effectively reduced and its stability can be improved, thereby achieving the goal of effectively controlling the construction cost.

In a preferred embodiment of the present utility model, two adjacent sleeves are arranged opposite one another.

In a preferred embodiment of the present utility model, the connection system between underwater tubular steel piles comprises 2-6 sleeves, e.g. 2, 3, 4, 5 and 6. The connection system between underwater tubular steel piles preferably comprises 2-4 sleeves, e.g. 2, 3 and 4. A small number of sockets is more advantageous for arranging the sockets on a tubular steel pile.

In a preferred solution of the present utility model, the inner diameter of the socket is larger than the diameter of the tubular steel pile. If the inner diameter of the socket is larger than the diameter of the tubular steel pile, the tubular steel pile can still sink gently into the position of the limiting device in a slightly inclined state, depending on its weight.

In a preferred solution of the present utility model, the inner wall of the sleeve is firmly connected to an expanded body. If the socket is sheathed outside of a tubular steel pile, the expanded body expands after it hits water and hits the outer wall of the tubular steel pile. After contact with water, an expanded adhesive tape fills the gap between the tubular steel pile and the socket and, due to its elasticity, increases the friction between the socket connection system and the tubular steel pile, thereby replacing weld seams.

In a preferred embodiment of the present utility model, the expanded body is glued to the entire inner wall surface of the sleeve.

In a preferred embodiment of the present utility model, the expanded body is an expanded adhesive tape.

In a preferred embodiment of the present utility model, the V-ledge plate is arranged along the height direction of a tubular steel pile, the end of the V-ledge plate having a smaller thickness on the upper side, while the other end has a greater thickness on the lower side.

In a preferred solution of the present utility model, the undersides of the adjacent V-ledge plates are at the same horizontal height.

In a preferred embodiment of the present utility model, the sleeve has a thickness of 10 mm to 20 mm. If the sleeve is in contact with a restriction device, the sleeve will bear large loads. In order to prevent the socket from being deformed by a force, it is necessary to set a suitable range of the thickness of the socket. If the thickness of the sleeve is less than 10 mm, the sleeve is easily deformed, which affects the stability of the connection system.

In a preferred solution of the present utility model, the rod part of the connection system comprises an upper transverse rod, a diagonal rod and a lower transverse rod.

The assembly method provided in the present utility model is characterized by simple operation and convenient construction, whereby the construction risk can be reduced and also the construction time and the difficulties in construction can be reduced.

When the inner wall of a socket is firmly connected to an expanded / expanded body, the specific procedure for assembling the expanded body in step 1 is as follows: First, the expanded body is placed in the inner wall of the socket and an opening is made at a suitable one Position of the expanded body open; L-shaped steel is welded to the inner wall of the socket to fix the expanded body after the L-shaped steel passes through an opening.

Further, in step 3, after the sleeve is firmly clamped and fixed, the adjacent sleeves are arranged in an opposite manner.
