Description

Technical Field

[0001] The utility model relates to the technical field of steel sheet pile guide frame construction, and more specifically, to a steel sheet pile guide frame for a dense sandy soil layer. Background Art

[0002] Steel sheet piles are a type of steel with a lock. There are many cross-sections of steel sheet piles, mainly straight plate type, groove type and Z type. They have the advantages of high strength and good waterproof performance. They are widely used in the construction of retaining walls, foundation pit enclosures and other fields.

[0017] The utility model is described in detail and completely below in conjunction with the accompanying drawings. A person of ordinary skill in the art will be able to implement the utility model based on these descriptions. Before describing the utility model in conjunction with the accompanying drawings, it should be particularly pointed out that the technical solutions and technical features provided in each part of the utility model, including the following description, can be combined with each other without conflict.

[0018] In addition, the embodiments of the present invention involved in the following description are generally only a part of the embodiments of the present invention, rather than all of the embodiments. Therefore, based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0019] The following is a further detailed description of the utility model in conjunction with the accompanying drawings and implementations, and its specific implementation process is as follows:

[0020] like Figures 1-2As shown, the utility model provides a guide frame for steel sheet piles 3 in a dense sand layer, comprising: a guide frame body 1 and a pressing assembly;

[0021] The guide frame body 1 has a plurality of through installation openings 2 on the top, the shape and specification of the installation openings 2 match the steel sheet piles 3, the arrangement of the plurality of installation openings 2 is the same as the installation of the steel sheet piles 3, and the plurality of installation openings 2 are alternately arranged in reverse connection and connected, forming a wave-like structure; a mounting groove 4 is provided at each installation hole on the top of the guide frame body 1, and a clamping assembly is provided in the mounting groove 4, and the clamping assembly is used to fix the clamping assembly, and is connected in a combined manner, which is convenient for later replacement and maintenance;

[0022] The clamping assembly includes a mounting seat 5 and a clamping seat 6 . The mounting seat 5 is fixed to the clamping assembly. The clamping seat 6 is connected to the mounting seat 5 . The clamping seat 6 is used to clamp the steel sheet pile 3 .

[0023] When the guide frame of the present application is in use, two steel sheet piles 3 are passed through the installation openings 2 at both ends of the guide frame body 1, and the steel sheet piles 3 are welded and fixed to the guide frame installation openings 2. During welding, the guide frame is ensured to be at the same height as the steel sheet piles 3 to avoid the guide frame from tilting. The two steel sheet piles 3 are then driven into the dense sand and soil, and the two driven steel sheet piles 3 are used as supporting feet for the guide frame. The remaining steel sheet piles 3 are then passed through the guide frame installation openings 2 in turn, and a clamping assembly is installed so that the clamping assembly is ballasted on one side of the steel sheet piles 3. The remaining steel sheet piles 3 are driven into the dense sand and soil in turn. After use, the guide frame is dismantled, and the dismantling environment is explored during dismantling, and places that may affect the dismantling are marked. Before dismantling, set up professional fixing equipment and protective measures to ensure that they are sufficiently firm and safe, then loosen the clamping assembly on the steel sheet pile 3, and then remove the clamping assembly from the installation groove 4 of the guide frame. Before dismantling, the steel sheet piles 3 at both ends of the guide frame are first cut open by cutting equipment, and then the guide frame is withdrawn from above the steel sheet pile 3 using lifting equipment.

[0024] The technical solution may also include the following technical details to better achieve the technical effect: the guide frame body 1 is an overall rectangular parallelepiped structure.

[0025] The technical solution may further include the following technical details to better achieve the technical effect: the size of the installation opening 2 is 5 to 10 mm larger than the size of the steel sheet pile 3 .

[0026] The present technical scheme may also include the following technical details to better achieve the technical effect: a plurality of gaskets are arranged on the side of the clamping seat 6 facing the steel sheet pile 3. During the insertion process, friction will occur between the steel sheet pile 3 and the clamping seat 6, causing wear of the clamping seat 6. By setting the gasket, the steel sheet pile 3 contacts the gasket, thereby reducing the wear on the clamping seat 6, making it convenient to directly replace the gasket of the clamping seat 6 later, and extending the service life of the clamping seat 6.

[0027] The technical solution may also include the following technical details to better achieve the technical effect: it also includes a connecting component, the connecting component is plugged and fixed with the pressing seat 6, and the connecting component is detachably fixed with the pressing seat 6, and the connecting component is connected to the mounting seat 5. Since the pressing seat 6 is in direct contact with the steel sheet pile 3, a certain amount of wear will occur. The pressing seat 6 can be quickly replaced by the connecting component, thereby ensuring that the steel sheet pile 3 is stably installed on the guide frame. In this embodiment, a connecting groove is provided on the pressing component, and a limit block is provided on the connecting component, and the limit block is plugged into the connecting groove to complete the fixation.

[0028] This technical solution may also include the following technical details to better achieve the technical effect: the mounting seat 5 is provided with a horizontally through-going internal threaded hole 7, one end of the adjusting bolt is threaded through the mounting seat 5 and connected to the pressing seat 6 / connecting assembly through a bearing, and the other end of the adjusting bolt is fixed with a hand wheel. The hand wheel facilitates the rotation of the adjusting bolt, and the distance between the pressing seat 6 and the steel sheet pile 3 is adjusted by the adjusting bolt to ensure that the steel sheet pile 3 is stably installed on the guide frame.

[0029] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation scheme. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the embodiments shown and described herein.
