Description

Technical Field

[0001] The utility model relates to the technical field of station pile support, in particular to an assembled station side wall top extension device. Background Art

[0002] In the pile support system, a jacking device is usually provided between the waist beam of the enclosure structure and the side wall of the assembly component. The longitudinal length of each ring of the existing assembly component is usually two meters. Two jacking devices are provided on one side of each ring, so four jacking devices need to be provided on the left and right sides of each ring. The side walls of the assembly components of the entire station need to use the jacking device. The existing jacking devices are as follows Figure 1 As shown. After the side wall is assembled, the jacking device is inserted between the waist beam and the side plate. After the support is removed, the water and soil pressure is transmitted to the side wall and middle plate of the assembled components through the waist beam of the enclosure structure and the jacking device, forming a complete force-bearing support system.

[0003] The existing jacking device has the following defects:

[0004] (1) Existing jacking devices are usually manufactured as standard parts, that is, the size of the jacking device is fixed. However, during the actual installation process, due to the influence of construction accuracy and the force on the retaining piles, the distance between the waist beam and the embedded steel plate of the side wall is not fixed. The spacing usually changes during the actual construction process. Therefore, the jacking device with fixed size is not suitable for construction situations where the actual distance often changes. For this reason, the solution usually adopted is: when the size of the jacking device is larger than the spacing between the waist beam and the side wall, the jacking device is cut on site; when the size of the jacking device is smaller than the spacing between the waist beam and the side wall, other components need to be inserted to ensure that the jacking device is in an interference fit with the waist beam and the side walls on both sides. As a result, the installation cost of the jacking device is greatly increased, and the installation efficiency of the jacking device is reduced.

[0005] (2) The existing jacking device is complicated to install: during the installation process, the jacking device needs to be hoisted by a crane and placed between the waist beam and the side wall. After the jacking device is installed, the workers must check the installation of the jacking device. If it is found that the connection between the jacking device and the waist beam and the side wall is not firm, other parts need to be inserted manually.

[0006] (3) The existing jacking device only uses the interference fit between the device and the waist beam and side walls on both sides to achieve the connection with the waist beam and side walls. Therefore, the connection between the jacking device and the waist beam and side walls is not reliable. In the actual construction process, the distance between the waist beam and the side wall will inevitably change. When the distance between the waist beam and the side wall increases, there is a risk of the jacking device falling. Utility Model Content

[0007] The purpose of the utility model is to overcome the above-mentioned defects of the prior art and proposes an assembled station side wall top extension device, which is easy to install, has a reliable connection between the assembled side wall and the retaining piles, is convenient to construct, has a low construction cost, and greatly improves the construction efficiency.

[0008] The technical solution of the utility model is: an assembled station side wall top extension device, which includes:

[0009] First mounting blocks: a plurality of first mounting blocks are fixed on one side of the assembled side wall facing the retaining piles, and there are gaps between the first mounting blocks and the retaining piles;

[0010] The second mounting block is slidably arranged in the gap between the first mounting block and the guard pile. The contact surfaces of the first mounting block and the second mounting block are both inclined surfaces, and the second mounting block is wedge-shaped.

[0011] In the utility model, the surface where the first mounting block is fixedly connected to the assembled side wall is a vertical side surface, the side where the first mounting block contacts the second mounting block is a first inclined surface, the inclined angle of the inclined surface is 60-80°, and there is a gap between the first inclined surface and the waist beam of the retaining pile;

[0012] The top dimension of the first mounting block is smaller than the bottom dimension thereof.

[0013] The vertical side surface of the first mounting block can be fixedly connected to the embedded steel plate of the assembled side wall by welding.

[0014] The side surface of the second mounting block facing the waist beam of the retaining pile is a vertical side surface, the side surface of the second mounting block in contact with the first mounting block is a second inclined surface, and the inclination angles of the first inclined surface and the second inclined surface are equal;

[0015] The top dimension of the second mounting block is larger than the bottom dimension thereof.

[0016] The first inclined surface of the first mounting block and the second inclined surface of the second mounting block are both provided with patterns or protrusions for increasing the friction coefficient.

[0017] The inclined angle between the first inclined surface and the second inclined surface is preferably 70°, which can effectively prevent the first mounting block from slipping off the second mounting block.

[0018] Pre-fix the first installation block on the assembled side wall, and hoist the assembled side wall to the construction site and outside the retaining pile;

[0019] After the middle plate of the assembled side wall is assembled, the second mounting block is inserted into the gap between the first mounting block and the retaining pile, and the second mounting block is hammered and fastened between the first mounting block and the waist beam.

[0020] The beneficial effects of the utility model are:

[0021] (1) Easy installation: During the installation process of the jacking extension device described in the present application, it is only necessary to insert the second installation block into the gap between the first installation block and the waist beam of the retaining pile, and then hammer it to fasten the second installation block between the first installation block and the retaining pile, which is very convenient to install;

[0022] (2) In the jacking device, the first mounting block and the assembled side wall are firmly fixedly connected, and according to the actual gap between the first mounting block and the waist beam of the retaining pile, the second mounting block can be inserted and tightened. Even if the distance between the assembled side wall and the retaining pile increases, the second mounting block will slide downward in the gap between the first mounting block and the side wall of the foundation pit. However, during the downward sliding of the second mounting block, the inclined surface on the first mounting block and the wedge shape of the second mounting block ensure that the distance between the first mounting block and the retaining pile is always smaller than the upper size of the second mounting block. Therefore, the second mounting block will not slide out of the gap between the first mounting block and the retaining pile. Therefore, the connection between the jacking device and the assembled side wall and the retaining pile is relatively reliable.

[0023] (3) The jacking extension device has a simple structure, is easy to manufacture, and has a low manufacturing cost; the jacking extension device is easy to install and has a high installation efficiency, which not only saves construction costs but also improves construction efficiency.

[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0030] The following description sets forth specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in a variety of other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the prefabricated station side wall top extension device described in the utility model comprises a first mounting block 1 and a second mounting block 2. A plurality of first mounting blocks 1 are fixed at intervals on the side of the prefabricated side wall 6 facing the retaining pile. A waist beam 4 is fixed on the side of the retaining pile 3 facing the prefabricated side wall. There is a gap between the first mounting block 1 and the side wall of the waist beam 4. The second mounting block 2 can be slidably inserted into the gap between the first mounting block 1 and the waist beam 4.

[0032] The side surface where the first mounting block 1 is connected to the prefabricated side wall 6 is a vertical surface, and the first mounting block is fixedly connected to the embedded steel plate 5 of the prefabricated side wall 6 through the vertical surface. In this embodiment, the first mounting block 1 is fixedly connected to the embedded steel plate 5 of the prefabricated side wall by welding. The side surface of the first mounting block 1 facing the side of the guardrail pile is a first inclined surface 101, and the inclination angle of the first inclined surface 101 is 60-80°. The top dimension of the first mounting block 1 is smaller than its bottom dimension. There is a gap between the first inclined surface 101 of the first mounting block 1 and the side wall of the waist beam.

[0033] The side surface of the second mounting block 2 facing the waist beam 4 is a vertical surface, and the second mounting block 2 contacts the waist beam 4 through the vertical surface. The side surface of the second mounting block 2 facing the first mounting block is a second inclined surface 201, and the inclined angle of the second inclined surface 201 is 60-80°, and the inclination angle of the first inclined surface 101 is the same as the inclination angle of the second inclined surface 201. The second mounting block 2 is a wedge-shaped block, that is, its top size is larger than its bottom size. The second mounting block 2 is slidably arranged in the gap between the first mounting block 1 and the side wall of the waist beam 4.

[0034] In this embodiment, the first mounting block 1 and the second mounting block 2 are both made of steel blocks. Patterns or protrusions may be provided on the first inclined surface 101 of the first mounting block in contact with the second mounting block, and on the second inclined surface 201 of the second mounting block in contact with the first mounting block. By providing these patterns or protrusions, the friction coefficient between the first mounting block 1 and the second mounting block 2 can be increased to prevent the first mounting block from slipping off from the second mounting block.

[0035] In this embodiment, the first inclined surface 101 and the second inclined surface 201 can be reasonably set to effectively prevent the first mounting block from slipping off from the second mounting block. Therefore, the optimal inclination angle of the first inclined surface 101 and the second inclined surface 201 is 70°.

[0036] During the construction process, after the first mounting block 1 is welded to the embedded steel plate 5 of the assembled side wall 6 in advance, the assembled side wall 6 is hoisted to the outside of the retaining pile 3. After the middle plate 7 of the assembled side wall 6 is spliced, the worker stands on the waist beam 4 fixed to the retaining pile 3, inserts the second mounting block 2 into the gap between the first mounting block 1 and the side wall of the waist beam, and performs appropriate hammering to tighten the second mounting block 2 between the first mounting block 1 and the side wall of the waist beam 4. After all the second mounting blocks are inserted and hammered, the installation of the jacking device described in the present application can be realized.

[0037] After the installation of the jacking device is completed, the first installation block 1 and the second installation block 2 are tightened to form a support between the assembled side wall 6 and the retaining pile 3. After the support is removed, the water and soil pressure in the retaining pile 3 is transmitted to the middle plate 7 of the assembled side wall 6 through the jacking device of the present application. Figure 4 shown.

[0038] Even if the distance between the prefabricated side wall and the guardrail pile changes, the jacking device can still well realize its supporting function. When the distance between the prefabricated side wall 6 and the guardrail pile 3 becomes smaller, the first mounting block 1 and the second mounting block 2 can better support the prefabricated side wall and the guardrail pile on both sides. When the distance between the prefabricated side wall 6 and the guardrail pile 3 increases, the spacing between the first mounting block 1 and the waist beam 4 increases. At this time, the second mounting block 2 moves downward in the gap formed between the first mounting block 1 and the waist beam 4. During the downward movement of the second mounting block 2, the distance between the vertical side of the first mounting block 1 and the vertical side of the second mounting block 2 also increases. Therefore, at this time, the first mounting block 1 and the second mounting block 2 can still support the prefabricated side wall 6 and the guardrail pile 3 on both sides.

[0039] The above is a detailed introduction to the assembled station side wall extension device provided by the utility model. Specific examples are used in this article to illustrate the principle and implementation method of the utility model.
