Description

Technical Field

[0001] The utility model relates to the technical field of steel trestle construction auxiliary equipment, in particular to an anti-scour reinforcement device for a steel trestle. Background Art

[0002] A steel trestle is a temporary steel structure used during bridge construction or maintenance. Typically constructed of steel, it boasts high load-bearing capacity and stability, serving as a temporary replacement for existing bridges for transportation. Compared to conventional bridges, steel trestles are faster to construct, making them suitable for temporary bridges. Depending on the intended use, the design width of a steel trestle is typically between 6 and 8 meters. Its structure includes steel pipe piles, bracing connecting steel casings, load-bearing beams atop the piles, Bailey trusses, distribution beams, and the bridge deck.

[0003] After each row of steel pipe piles has sunk into place, the piles must be connected to each other. That is, a connection system must be installed on their upper part to connect all the steel pipe piles into a whole and increase the stability of the piles. The connection system is made of steel sections or steel casings, and is connected by welding or bolting. It is usually installed above the water surface. When the water flow is prolonged or when a sudden large flow of water is encountered, the impact of the lateral water flow on the trestle steel pipe piles is mainly balanced and offset by the upper connection system and the part embedded in the riverbed. However, since the riverbed itself is not a stable structure, the steel pipe piles embedded in the riverbed are easily displaced by force. When the limit value is exceeded, the upper connection system will be damaged, further causing the bridge to become unstable. Utility Model Content

[0004] The utility model aims to provide a steel trestle anti-scouring reinforcement device to solve the problem that during the use of the steel trestle, the steel pipe piles embedded in the riverbed are displaced after being scoured, causing the bridge to become unstable.

[0005] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0006] A steel trestle anti-scour reinforcement device comprises a left clamp, a right clamp and a connecting rod;

[0007] The left clamp is clamped on the steel pipe pile of the steel trestle and includes a water-expanding water stop strip arranged on the inner side;

[0008] The right clamp has the same structure as the left clamp and is clamped on the adjacent steel trestle steel pipe pile on the right side;

[0009] Connecting rod, the left end of which is connected to the left clamp, and the right end of which is connected to the right clamp;

[0010] After the left clamp and the right clamp clamp the steel trestle steel pipe pile, when the water-swellable waterstop strip expands when exposed to water, it fills the gap between the clamp and the steel trestle steel pipe pile, forming a stable connection.

[0011] As a further technical solution of the above scheme, the left clamp includes a left half ring and a right half ring; a water stop strip that expands when exposed to water is provided on the inner side of the left half ring and the right half ring, and a first connecting hole is provided on the outer side wall of the left half ring and the right half ring; a second connecting hole matching the first connecting hole is provided at the left and right ends of the connecting rod.

[0012] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0013] The utility model arranges a left clamp and a right clamp on the steel pipe piles of the steel trestle and connects them with a connecting rod; after the left clamp and the right clamp fall to the bottom of the riverbed, the water stop strip expands when encountering water and fills the gap, thereby achieving a firm connection and maintaining the stability of the bridge.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, so as to have a further understanding of the concept of the present invention, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.

[0020] like Figures 1 to 4 As shown, a steel trestle anti-scour reinforcement device includes a left hoop 1, a right hoop 2 and a connecting rod 3;

[0021] The left clamp 1 is clamped on the steel trestle steel pipe pile 4 and includes a water-swelling water stop 5 provided on the inner side;

[0022] The right clamp 2 has the same structure as the left clamp 1 and is clamped on the adjacent steel trestle steel pipe pile on the right side;

[0023] Connecting rod 3, the left end of which is connected to the left clamp 1, and the right end of which is connected to the right clamp 2;

[0024] After the left clamp 1 and the right clamp 2 clamp the steel trestle steel pipe pile 4, when the water-swellable waterstop strip 5 expands when exposed to water, it fills the gap between the clamp and the steel trestle steel pipe pile 4 to form a stable connection.

[0025] When using this device, first install the left clamp 1 and the right clamp 2 on the adjacent steel trestle steel pipe piles 4. Do not tighten them during installation, and leave a certain gap between the clamps and the steel trestle steel pipe piles 4. Use the connecting rod 3 to connect the left clamp 1 and the right clamp 2 respectively. The left clamp 1 and the right clamp 2 fall under their own weight. During the falling process, the connecting rod 3 ensures synchronous falling. After falling to the bottom of the riverbed, the water-swelling waterstop strips 5 on the inside of the left clamp 1 and the right clamp 2 expand and come into close contact with the steel trestle steel pipe piles 4, forming a stable connection under water. After the riverbed cover layer is washed away, the steel pipe piles originally embedded in the riverbed will not be displaced or deformed, and the steel trestle steel pipe piles 4 can still have two upper and lower force points to resist the impact of lateral water flow, greatly enhancing the overall stability of the steel trestle.

[0026] like Figure 2 As shown, as a preferred embodiment, the left clamp 1 comprises a left half-ring 11 and a right half-ring 12. Water-swelling waterstop strips 5 are installed on the inner sides of the left and right half-rings 11, 12, and first connecting holes 13 are provided on the outer walls of the left and right half-rings 11, 12. The connecting rod 3 has second connecting holes 31 on both its left and right ends that match the first connecting holes 13. In this embodiment, the left clamp 1 is tightened by snapping the left and right half-rings 11, 12 together. It is then connected to the connecting rod 3 via the first and second connecting holes 13, 31. The right clamp 2 is then lowered after the same installation is completed. PN-type water-swelling waterstop strips can be used. PN-type water-swelling waterstop strips combine the good adhesion and low-temperature performance of conventional putty with superior expansion characteristics and higher strength than conventional putty, making them particularly suitable for waterproofing projects.

[0027] The words "connection" and "fixation" appearing in the description of the present invention may refer to fixed connection, processing and forming, welding, or mechanical connection. The specific meanings of the above terms in the present invention shall be understood according to the specific circumstances.

[0028] In the description of the present invention, the terms "center", "upper", "lower", "horizontal", "inner", "outer", etc., which indicate the orientation or position relationship, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
