Description

Technical Field

[0001] The invention belongs to the technical field of foundation pit support, and in particular relates to a support system for a deep foundation pit in a complex stratum. Background Art

[0002] In recent years, with the rapid rise of high-rise buildings and the development and utilization of urban underground space, foundation pits have become increasingly deep. This is particularly true in densely populated areas, making foundation pit support technology increasingly important. Foundation pit support refers to a series of measures implemented in earthwork projects to ensure the stability and safe construction of the foundation pit. This involves ensuring the safety of the entire support structure during construction while also controlling deformation of the support structure and the surrounding soil to ensure the safety of the surrounding environment. Internally supported support structures are often used for deep and large foundation pits, as well as for those requiring high safety.

[0003] The conventional practice of the existing foundation pit support structure is pile foundation support. First, a drilling rig is used to drill the pile foundation. After the drilling is completed, the pile foundation grouting operation is carried out. Then, reinforced concrete grouting material is injected into the drill hole to fill the pores and form a pile foundation support structure. Before the grouting material solidifies, pre-buried steel bars or steel cages are installed. After the grouting material is fully solidified, the pile foundation is solidified to form retaining piles. A plurality of retaining piles arranged in parallel are used as the support structure of the foundation pit and fixed in the soil around the foundation pit to enhance the stability of the soil. For the above-mentioned foundation pit In terms of support measures, when faced with a deep and large foundation pit, only the retaining piles are relied upon as the support structure of the foundation pit. Correspondingly, there is a lack of supporting structure to support the retaining piles, and there is still a defect of insufficient stability of the foundation pit. In addition, for foundation pits of different shapes, the establishment of a peripheral support structure is very necessary, especially for the corners of the foundation pit, which are more unstable. Moreover, for foundation pits of different specifications, there is a lack of support components to adapt and support them and increase their protection, which greatly affects the progress of construction work and cannot meet the use requirements.

It is designed for different usage requirements of the side protection component 5. It can adapt the position of the end protection component 8 to ensure that it is in a relatively horizontal position, providing a prerequisite for subsequent support.

[0030] In the above process: the mobile adjustment component 3 is used to be conveniently adjusted in the horizontal direction, driving the support component to move toward the position of the side of the foundation pit, and adapting to foundation pits of different specifications in the horizontal direction, thereby improving the functionality of the device. The longitudinal adjustment component 7 is used to adapt to foundation pits of different specifications in the longitudinal direction, and the cooperation of the side protection component 5 and the end protection component 8 can adapt to the side of the foundation pit and the end face adjacent to the side under the above-mentioned mobile adjustment, thereby greatly improving its support performance and ensuring the use effect. The independent leveling component 9 can adaptively adjust the position of the end protection component 8 according to the different usage requirements of the side protection component 5, ensuring that it is in a relatively horizontal position, providing a prerequisite for subsequent support. The device is reasonably designed, simple in structure, easy to process and can support the support structure previously established in the foundation pit. It is especially suitable for foundation pits of different shapes and specifications, improves the stability of the support structure, prevents soil collapse and lateral displacement, ensures the stability of the foundation pit itself, fully improves the work process, and effectively meets usage requirements.

[0031] In order to ensure the stability of the position where the device is set up, the stable installation component includes a support platform 21, which can be set up according to the center position in the foundation pit, and also provides convenience for the establishment of the support leg 10.

Furthermore, the rotatable setting of the adjusting plate 103 enables the equipment to be adapted and supported according to different foundation pit bottom surfaces to ensure the stability of its position. Then, according to the actual working conditions, the adjusting cylinder 104 is controlled, and its extension and contraction are used to adjust the inclination angle of the adjusting plate 103 to realize the adjustment of different use heights of the support platform 21, thereby ensuring the smooth progress of subsequent support work.

[0032] In order to achieve convenient adjustment of the position of the side support plate 52, the rotation drive assembly 6 includes a connecting plate 61 connected to the rotating plate 51, and a connecting seat 62 is provided between the two connecting plates 61. A driving cylinder 63 is provided on the carrier plate 4, and its output end is hinged to the connecting seat 62. After the side protection assembly 5 is driven by the moving adjustment assembly 3 and moves to the appropriate position, the driving cylinder 63 is controlled to operate so that it acts on the rotating plate 51, causing the lower side of the rotating plate 51 to rotate relative to the carrier plate 4, thereby completing the adjustment of the position of the side support plate 52, meeting the use requirements of the inner walls of different foundation pits, and ensuring the stability of the support.

[0033] In order to adapt to foundation pits of different specifications, especially after the support of the first foundation pit side is completed, to ensure the smooth implementation of the end support work adjacent to it, the longitudinal adjustment component 7 includes a key-shaped seat 71, a rotating rod 72 is provided between the two key-shaped seats 71, a shell 73 is provided on one side of the rotating rod 72, and an ear seat 74 is provided on the outside of the shell 73 for use with the rotating rod 72. For the above-mentioned establishment, the shell 73 and the telescopic shell 75 can be rotated relative to the rotating plate 51 by utilizing the established rotating rod 72. At the same time, with the cooperation of the leveling component 9, the position of the shell 73 is adjusted, especially to make it in a relatively horizontal position. In order to provide convenient conditions for the implementation of subsequent actions of the equipment, a telescopic shell 75 is provided in the shell 73. The telescopic shell 75 can be telescoped and moved relative to the inner side of the shell 73. A telescopic cylinder 76 is provided on the other side of the shell 73. The output end of the telescopic cylinder 76 is connected to one side of the telescopic shell 75. It is specifically described as follows: the mounting end of the telescopic cylinder 76 is rotatably connected to one side of the shell 73, and its output end is connected to one side of the telescopic shell 75. The telescopic cylinder 76 can be used to move and adjust the telescopic shell 75 relative to the shell 73, and then move and adjust the end edge protection component 8 to different positions to meet different usage requirements.

A hydraulic cylinder 93 is provided below the L-shaped seat 91, and its output end passes through the L-shaped seat 91 and is connected to the lifting block 92. A mounting ear 94 with a concave shape is provided below the shell 73, and an adjusting rod 95 with a Z-shaped design is provided in the mounting ear 94. The two adjusting rods 95 are arranged in a mirror image, and their lower ends are rotatably connected to the lifting block 92. The specific description is: Taking into account that when the side protection assembly 5 supports the foundation pit at an inclined angle, since the end edge protection assembly 8 is set up based on the rotating plate 51, in order to ensure the end The edge protection assembly 8 is always in a relatively horizontal position, so a leveling assembly 9 is set up. Further, when the rotating plate 51 is in a vertical state, the hydraulic cylinder 93 is controlled to extend, and the adjustment rod 95 is used to support the bottom of the longitudinal adjustment assembly 7 in an inclined state, so that it has good stability. When the rotating plate 51 changes from a vertical to an inclined state, the hydraulic cylinder 93 is controlled to contract, driving the lifting block 92 to slide downward relative to the L-shaped seat 91. At the same time, with the help of the established adjustment rod 95, the longitudinal adjustment assembly 7 will be pulled from the inclined trend to a horizontal state to a certain extent. In this way, in the subsequent use of the end edge protection assembly 8, it will be placed in a relatively horizontal position against the inner wall of the foundation pit, ensuring the effective implementation of its supporting action and meeting the use requirements.

[0035] The cam 83 is connected to the support frame 81 and the support frame 82 is connected to the support frame 81 so as to adjust the support frame 81 to the inner wall of the other side of the foundation pit. The movable gear 112 and the outer side of a rotating rod 84 are provided with an adjusting gear 113, which is meshed with the active gear 112. The specific description is: after the support assembly is adjusted to the appropriate position, the longitudinal adjustment assembly 7 is controlled to operate, driving the end edge protection assembly 8 to extend and move toward the outside. After the moving position is appropriate, according to the actual situation of the inner side of the foundation pit it is close to, such as a vertical surface or an inclined surface, the drive motor 111 is controlled to operate, so that it drives the active gear 112 to rotate and acts on the adjusting gear 113, thereby causing the rotating rod 84 to rotate relative to the support seat 83. Among them, one group of angle adjustment assemblies 11 can only control one end support plate 82 on one side of the rotating frame 81, that is, the two groups of angle adjustment assemblies 11 are controlled to operate respectively, so that they drive the upper and lower end support plates 82 to adjust so that they are adapted to the inner wall of the foundation pit, thereby ensuring the realization of the support effect and greatly improving the functionality of the device.

[0036] The cam 77 is fixed on the upper end of the cam 77 so that the cam 77 can be adjusted relative to the cam 77. The cam 77 is fixed on the lower end of the cam 77 so that the cam 77 can be adjusted relative to the cam 77. 710 is connected to its outer end surface, and the second concave seat 79 is sleeved on the outside of the limit frame 710, and is established by the sliding seat 712 and the sliding bar 711, which can limit the limit frame 710 along the moving direction of the telescopic shell 75 and fully improve its stability during the movement. In addition, a bracket can be added to the outside of the shell 73 between the first concave seat 78 and the second concave seat 79, especially to support and limit the telescopic adjustment of the limit frame 710 to prevent it from shifting. When the longitudinal adjustment component 7 moves to the appropriate position, the rotation adjustment cylinder 713 is controlled to operate, so that it drives the rotating frame 81 to rotate outward relative to the longitudinal adjustment component 7, especially to approach the other inner wall of the foundation pit, to ensure that the end support component supports and protects the other inner wall of the foundation pit, and improves the support stability.

For different usage requirements, multiple units can be freely added, and the connection between two adjacent frame 31 units is achieved by using a bolt assembly at the connecting sleeve 33 to meet different usage requirements. For the established mobile assembly 35, it is established at the concave corner of the connecting frame 341. At the same time, two sets of limiting wheels 352 are arranged vertically, respectively contacting the top and side surfaces or bottom and side surfaces adjacent to the frame 31, which can not only ensure the stability of the movable adjustment component 3, but also ensure its smoothness during use. In addition, the movable adjustment component 3 is set up in advance according to the specifications of the foundation pit, that is: one side of the frame 31 is connected to the stable placement component 2, and the other side can be against the inner side of the foundation pit, thereby ensuring the stability of the movable adjustment component 3, preventing it from shifting, and meeting the use requirements.
