Description

Technical Field

[0001] This utility model relates to the field of energy-saving control, specifically to a hydraulically supported waler for sheet piles. Background Technology

[0002] The internal support of sheet pile support is usually provided by walers. Generally speaking, since the size of the sheet piles needs to be determined according to the on-site construction dimensions, the walers, as supporting components, are usually fabricated on-site.

[0003] In existing waler structures, H-beams or seamless steel pipes are mostly used for support.

[0004] The connection between the walers and the sheet piles requires welding corbels at an appropriate height on the side wall after the sheet piles are driven. The walers are then installed on the corbels and fixed by welding to form an internal support structure. H-beams are used as support members between the walers.

[0005] Due to the on-site fabrication characteristics of the waler structure, a large amount of welding work is required to connect them. When dismantling, cutting machines or gas cutting are needed for removal, and then the material is discarded as waste. On the one hand, the reuse value is low, and on the other hand, it causes a large waste of manpower, resulting in high construction costs. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by providing a reusable, easy-to-assemble and disassemble, and efficient steel sheet pile hydraulic support waler.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a steel sheet pile hydraulic support waler, including a waler, an expansion joint, and a hydraulic jack assembly;

[0008] The expansion joints are arranged in groups of at least two, and the expansion joints in a group are parallel to each other.

[0009] The walers are arranged in pairs at both ends of a set of expansion joints, and the outer end face of the walers forms a support surface;

[0010] The hydraulic jack assembly includes at least one hydraulic jack and an oil circuit. The two ends of the hydraulic jack are hinged between two walers as a support structure. The expansion joint serves as a linear guide mechanism. The oil inlet and outlet of the oil circuit are located on the expansion joint or the waler.

[0011] Preferably, the number of expansion joints is equal to the number of hydraulic jacks.

[0012] Preferably, a set of expansion joints includes three expansion joints.

[0013] Preferably, the hydraulic jack is installed inside the expansion joint.

[0014] Preferably, the waler is made of H-beam steel.

[0015] Preferably, the waler is provided with lifting holes at both ends.

[0016] Preferably, the length of the waler is 4m-5m.

[0017] Preferably, an expansion joint is installed 20-30cm from the end of the waler.

[0018] Preferably, the spacing between adjacent expansion joints is 2m-2.5m.

[0019] Preferably, the waler has a plurality of hanging holes.

[0020] This utility model has substantial features and advancements compared to existing technologies. Specifically, it utilizes hydraulic jacks in conjunction with expansion joints to support the inner side of the waler, forming an adjustable-width support waler. After the sheet pile construction is completed, the support waler is placed inside the sheet pile and adjusted to a suitable support width. The number and specifications of the walers used are determined according to the specifications of the sheet pile to complete the support of the sheet pile. After the support is completed, the walers can be removed and stored for later use, achieving reuse. Compared to traditionally temporarily prepared walers, it has the advantages of strong reusability, high utilization efficiency, and high installation efficiency, thereby saving construction costs.

[0025] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0026] like Figs. 1-3 As shown, a steel sheet pile hydraulically supported waler includes a waler 1, an expansion joint 2, and a hydraulic jack assembly.

[0027] The expansion joints 2 are in groups of at least two, and the expansion joints 2 in a group are parallel to each other. In this embodiment, each supporting waler includes three expansion joints 2. The expansion joints 2 are made of steel pipe sleeves. The expansion joints 2 play a guiding role during expansion and contraction in the structure, and also play a supporting role in the radial direction.

[0028] Several pin holes 4 are provided on the side wall of the expansion joint 2, which can be used as a backup protection measure. When the hydraulic jack 3 is opened to the position, the corresponding pin holes are locked with pins to avoid the risk of hydraulic system failure and pressure release, which could lead to failure of the supporting waler.

[0029] The walers 1 are arranged in pairs at both ends of a set of expansion joints 2. The outer end face of the walers 1 forms a support surface. In this embodiment, the walers 1 are made of H-beams. The length of a single waler 1 is about 4m-5m. An expansion joint is set 20-30cm from the end of the waler. The distance between adjacent expansion joints is 2m-2.5m.

[0030] Lifting holes 11 are provided at both ends of the waler 1 for use with a crane to suspend, move and install the waler. Several hanging holes 12 are also provided in the middle of the waler 1. The main function of the hanging holes 12 is to suspend the waler when it is installed. Since the waler is suspended when supporting the sheet pile 6, several hooks can be welded to the inner wall of the sheet pile 6, with the traditional corbel support. Then, the waler is suspended inside the sheet pile 6 using the hanging holes 12. If necessary, the hooks can increase the height adjustment capability, or several hooks of different heights can be set to adjust the waler support height.

[0031] The hydraulic jack assembly includes at least one hydraulic jack 3 and an oil circuit 5. In this embodiment, the number of hydraulic jacks is equal to that of the telescopic joint to ensure the balance of force distribution. The two ends of the hydraulic jack 3 are hinged between the two walers 1 as a support structure. The telescopic joint 2 serves as a linear guide mechanism. The oil inlet 51 and oil return port 52 of the oil circuit 5 are set on the telescopic joint or the waler. To ensure the aesthetics and simplicity of the structure, the hydraulic jack 3 is hidden inside the telescopic joint 2, and the oil circuit is also hidden in the internal space of the telescopic joint 2 and the waler, with only the oil inlet 51 and oil return port 52 exposed to facilitate the connection of external hydraulic oil supply equipment.

[0032] Work process description:

[0033] During construction, after the sheet piles are driven, the excavation is carried out to the designed waler installation position. Then, the supporting waler is hoisted into place by a crane. It is connected to the hydraulic oil pipe machine above the pre-installation position. Oil is injected to open the waler according to the support width of the sheet pile 6, and the angle is adjusted until the supporting surface of the waler is tightly pressed against the inside of the sheet pile.

[0034] To prevent the sheet pile support structure from falling off due to construction disturbance or foundation pit displacement, hooks are installed at corresponding positions on the sheet piles. The walers are suspended and connected to the hooks through the hanging holes 12 for protection. The installation height of the hooks can be adjusted if necessary.

[0035] After securing the expansion joint, insert a pin through pin hole 4 on the expansion joint to lock it, providing secondary protection and preventing sudden pressure release from the hydraulic cylinder from causing displacement or collapse of the enclosure structure.

[0036] This solution reduces the manpower and material resources required for sheet pile welding and thermal cutting. A single support waler can be used to support sheet piles of different widths between 3 and 5 meters. Wider sheet piles can be supported by multiple hydraulic support walers of the same or different specifications. It is highly flexible, reusable, relatively easy to install and dismantle, has a shorter construction cycle, and saves project costs. It is particularly suitable for the construction of linear sheet pile support structures with many specifications and different support widths.

[0037] Finally, it should be noted that: the preferred embodiments of this patent have been described in detail above, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
