Description

Technical Field

[0001] The present application relates to the field of foundation pit support, and in particular to a multi-row pile support structure for raising the ground. Background Art

[0002] With the rapid development of urban construction, there are more and more deep foundation pit projects, and the construction difficulty is getting greater and greater. Various foundation pit support methods have emerged. Pile structure is widely used in the field of domestic deep foundation pit engineering due to its good deformation control effect, strong support structure stability and strong applicability.

[0003] Among the existing vertical support systems, the most common method is to use reinforced concrete piles for support. Generally, the location of the foundation pit is determined first, and then evenly distributed deep holes are drilled at the edge of the foundation pit area. Then, reinforced concrete piles are poured in the holes, and then the foundation pit is excavated.

[0004] At present, for foundation pit support projects with constructed vertical support systems, if there is an increase in ground elevation, such as earth accumulation caused by changes in development plans, new roads built in the surrounding area, etc., if the original vertical support pile structure design remains unchanged, the foundation pit support depth will be deepened, and the original support system will not be able to provide sufficient support.

[0010] By adopting the above technical scheme, evenly distributed high-position support piles are poured between the support piles and the elevated soil layer of the earth accumulation, so that the high-position support piles can support the high-position soil layer of the earth accumulation, thereby reducing the movement of the high-position soil layer toward the foundation pit, providing sufficient resistance for the foundation pit support, improving the protection of the environment around the foundation pit, and ensuring the safety and stability of the foundation pit.

[0011] Furthermore, a top support plate is slidably connected to the waist beam, connecting short beams are arranged at intervals on the waist beam, and a plurality of top support hydraulic rods are arranged at fixed intervals on the waist beam, and the telescopic ends of the top support hydraulic rods are fixedly connected to the top support plate.

[0012] By adopting the above technical scheme, the telescopic end of the top support hydraulic rod is used to drive the top support plate to contact the surrounding purlin one, so that the surrounding purlin one waist beam is further supported, and then the corresponding connecting short beam is installed according to the width between the surrounding purlin one and the waist beam, so that the connecting short beam can be used to connect the surrounding purlin one and the waist beam, and the supporting force is transmitted to the waist beam, thereby strengthening the integrity of the support structure. The hydraulic rod mechanism can actively control the force applied to the high-position support structure, effectively protect the safety of the surrounding environment of the foundation pit, and improve the safety and stability of the foundation pit.

[0023] After the construction of the support piles 2 is completed in the foundation pit 1, when the site conditions change and earthwork piles appear at the edge of the foundation pit 1, an upper high-position support structure 6 is set between the earthwork piles and the plurality of support piles 2, and the high-position support structure 6 is used to block the earthwork piles above the edge of the foundation pit 1. At the same time, a purlin 3 is constructed on the plurality of support piles 2 as the earthwork is excavated, and then the purlin 3 is supported by the support beam 4, and then a retaining wall 5 is constructed on the side of the plurality of support piles away from the foundation pit 1, and the retaining wall 5 is used to block the water in the soil, and then a safety guardrail 7 is installed on the high soil layer to support the edge of the foundation pit 1. That is, when earthwork increases at the edge of the foundation pit 1, an upper high-position support structure 6 is set between the original support piles 2 and the earthwork piles, so that the high-position support structure 6 can support the earthwork piles, reduce the possibility of earthwork falling into the foundation pit 1, improve the safety and stability of the foundation pit 1, and protect the safety of the surrounding environment of the foundation pit 1.

[0024] Reference Figure 1 and Figure 2 The high-position support structure 6 includes a plurality of high-position support piles 61 evenly arranged on one side of the increased soil layer 8. The high-position support piles 61 penetrate into the edge of the foundation pit 1. A waist beam 63 is fixed between the high-position support piles 61 and the support piles 1 2. A purlin 2 62 is arranged on one side of the increased soil layer 8. The purlin 2 62 is fixedly connected to the plurality of high-position support piles 61.
