Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a steel temporary bridge and steel sheet pile collaborative support device. Background Technology

[0002] Bridges play a vital role as important transportation infrastructure connecting two banks. Steel temporary bridges, as a special type of bridge, demonstrate their value in many scenarios due to their advantages. Steel temporary bridges are temporary or simple bridges constructed primarily of steel. They are lightweight, quick to erect, and can often meet traffic needs in a short time. Steel sheet piles are interlocking steel structures that can be freely combined through edge linkage devices to form continuous retaining walls or water-retaining walls. They are widely used in civil engineering fields such as foundation pit support and cofferdam construction.

[0003] In the construction of existing temporary steel bridges, steel sheet piles are first driven into the position where steel pipe piles are placed for support. Because the steel sheet piles and steel pipe piles are supported separately during construction, the protective structure is singular and cannot form a mutually supporting structure. When one of the supports breaks under stress, it can easily lead to the destruction of the entire structure and affect construction. Therefore, we propose a steel temporary bridge and steel sheet pile collaborative support device to solve the above-mentioned problems. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a steel temporary bridge and steel sheet pile collaborative support device. It can provide collaborative support for steel sheet piles and steel pipe piles. When one of the support structures is fractured under stress, the overall support structure is not affected, which buys time for subsequent emergency repairs and ensures the normal progress of construction.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A steel temporary bridge and steel sheet pile collaborative support device includes steel pipe piles and jackets symmetrically installed on the steel pipe piles. A first support arm and a second support arm are symmetrically installed on both sides of the root of the steel pipe piles.

[0009] Both ends of the first support arm are provided with assembly grooves, and a first pin hole penetrating the first support arm is provided at the assembly groove.

[0010] Both ends of the second arm guard are integrally formed with locking blocks that engage with the assembly groove, and the locking blocks are provided with second pin holes corresponding to the first pin holes;

[0011] Two symmetrically arranged jackets are respectively equipped with a first arm arranged in a parallel structure and a second arm arranged in a cross structure. The edge of each jacket is integrally formed with a mounting ear, and a locking bolt for fixing the first arm and the second arm is inserted into the mounting ear.

[0012] The lower part of the jacket is provided with a fixing seat that engages with and is fixed to the first support arm for the steel pipe pile.

[0013] Furthermore, a reinforcing block with a right-angled triangular structure is installed at the corner where the ends of the first and second guard arms meet.

[0014] Furthermore, the reinforcing block is provided with mounting holes, and the first support arm and the second support arm are provided with screw holes corresponding to the mounting holes.

[0015] Furthermore, the card block and the assembly slot form an embedded structure.

[0016] Furthermore, both ends of the first arm and the second arm are provided with mounting holes, and the mounting holes are assembled and connected with the locking bolts.

[0017] Furthermore, the fixing seat has a slot for engaging with the steel pipe pile.

[0018] Furthermore, the base of the fixed seat is provided with symmetrical mounting holes, and the first support arm is provided with screw holes corresponding to the mounting holes.

[0019] 3. Beneficial effects

[0020] Compared with existing technologies, the advantages of this utility model are:

[0021] (1) In this scheme, the first and second protective arms are connected by splicing between the assembly groove and the clamping block, so that the first and second protective arms abut against the inner wall of the steel sheet pile. Finally, the clamping block is fixed in the assembly groove by passing the first and second pin holes with pins to support the steel sheet pile. Then, the steel pipe pile is driven into the stratum in the cofferdam. The first arm is installed in parallel between the two sleeves with locking bolts, and the second arm is installed crosswise between the two sleeves with locking bolts. Finally, the steel pipe pile is clamped and fixedly connected to the first protective arm by the fixing seat. Through this collaborative support structure, the steel sheet pile and the steel pipe pile can be supported in a coordinated manner. When one of the support structures is broken by stress, the overall support structure is not affected, which buys time for later emergency repairs and ensures the normal progress of construction.

[0022] (2) In this solution, a reinforcing block with a right-angled triangular structure is installed at the corner where the ends of the first guard arm and the second guard arm meet. This enhances the strength, rigidity and torsional resistance of the first guard arm and the second guard arm. It can overcome the product distortion caused by uneven stress due to the difference in wall thickness between the first guard arm and the second guard arm, thereby increasing the strength of the joint surface and improving the support effect.

[0032] Example:

[0033] Please see Figure 1-6 The steel temporary bridge and steel sheet pile collaborative support device includes a steel pipe pile 1 and a jacket 2 symmetrically installed on the steel pipe pile 1. A first support arm 3 and a second support arm 4 are symmetrically installed on both sides of the root of the steel pipe pile 1.

[0034] Both ends of the first guard arm 3 are provided with mounting grooves 5, and the mounting grooves 5 are provided with first pin holes 6 that penetrate the first guard arm 3.

[0035] Both ends of the second guard arm 4 are integrally formed with locking blocks 7 that engage with the assembly groove 5. The locking blocks 7 are provided with second pin holes 8 corresponding to the first pin hole 6.

[0038] It should be noted that when using this steel temporary bridge and steel sheet pile collaborative support device, firstly, after driving steel sheet piles into the area where steel pipe piles 1 are being constructed to form a cofferdam, water is pumped out and silt is cleared. Then, the first support arm 3 and the second support arm 4 are connected by splicing the assembly groove 5 and the locking block 7, so that the first support arm 3 and the second support arm 4 abut against the inner wall of the steel sheet piles. Finally, the locking block 7 is fixed in the assembly groove 5 by using pins passing through the first pin hole 6 and the second pin hole 8 to support the steel sheet piles. After that, the steel pipe piles 1 are driven into the... In the strata within the cofferdam, the first support arm 10 is installed parallel between two sleeves 2 using locking bolts 12, and the second support arm 11 is installed crosswise between two sleeves 2 using locking bolts 12. Finally, the steel pipe pile 1 is secured and fixedly connected to the first support arm 3 using a fixing seat 13. Through this collaborative support structure, the steel sheet piles and steel pipe piles 1 can be supported in a coordinated manner. When one part of the support structure breaks under stress, the overall support structure is not affected, thus buying time for subsequent emergency repairs and ensuring the normal progress of construction.

[0039] like Figure 4 As shown, a reinforcing block 9 with a right-angled triangular structure is installed at the corner where the ends of the first guard arm 3 and the second guard arm 4 meet. The reinforcing block 9 has an assembly hole, and the first guard arm 3 and the second guard arm 4 have screw holes corresponding to the assembly hole.

[0040] It should be noted that by installing a reinforcing block 9 with a right-angled triangular structure at the corner where the ends of the first guard arm 3 and the second guard arm 4 meet, the strength, rigidity, and torsional resistance of the first guard arm 3 and the second guard arm 4 are enhanced. This can overcome the product distortion caused by uneven stress due to the difference in wall thickness between the first guard arm 3 and the second guard arm 4, thereby increasing the strength of the joint surface and improving the support effect.

[0046] It should be noted that this facilitates the installation and fixation of the fixing seat 13, while ensuring the stability of the assembly between the fixing seat 13 and the steel pipe pile 1.

[0047] In use: First, after driving steel sheet piles into the area where steel pipe pile 1 is being constructed to form a cofferdam, water is pumped out and silt is removed. Then, the first support arm 3 and the second support arm 4 are connected by splicing between the assembly groove 5 and the clamping block 7, so that the first support arm 3 and the second support arm 4 abut against the inner wall of the steel sheet pile. Finally, the clamping block 7 is fixed in the assembly groove 5 by passing pins through the first pin hole 6 and the second pin hole 8 to support the steel sheet pile. After that, the steel pipe pile 1 is driven into the stratum in the cofferdam. The first support arm 10 is installed parallel between the two clamps 2 by locking bolts 12, and the second support arm 11 is installed crosswise between the two clamps 2 by locking bolts 12. Finally, the steel pipe pile 1 is clamped and fixedly connected to the first support arm 3 by the fixing seat 13.
