Description

Technical Field

[0001] This utility model relates to the field of geotechnical construction support technology, specifically a foundation support structure for geotechnical construction. Background Technology

[0002] From an engineering and construction perspective, geotechnical engineering refers to any type of rock and soil that makes up the Earth's crust. Geotechnical engineering mainly focuses on solving engineering problems related to rock and soil masses. Excavation of foundation pits is an essential part of geotechnical engineering construction. During the excavation of foundation pits, the surrounding soil will deform. After the foundation pit is excavated, due to its large depth, the support strength of the foundation pit side surface is poor. The buildings around the foundation pit side surface may collapse due to the instability of the foundation pit side surface. Therefore, in order to ensure the smooth construction of the foundation pit and the safety of the surrounding buildings, a support structure is set between the foundation pit and the foundation pit side wall.

[0003] However, existing construction support structures for soil and rock foundation pits have the following problems during use: While these structures primarily use steel supports to reinforce the edges of the pit, providing good support and stability, soil from both sides of the pit is prone to falling into the pit during rainy weather, especially for open-pit pits where there is a lack of specific protective measures and structures. Therefore, it is necessary to design corresponding technical solutions to address these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a foundation support structure for geotechnical construction, which solves the technical problem that existing geotechnical foundation pit construction support structures mainly use steel structure supports to support the edges of the foundation pit. Although they have good support effect and stability, the soil on both sides of the foundation pit is prone to fall into the foundation pit with the flow of water when it rains. This is especially true for open-air foundation pits, where there is a lack of targeted protection measures and structures.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foundation support structure for geotechnical construction, comprising a support frame and two sets of protective components installed on both sides of the support frame. The support frame is built into the geotechnical foundation pit and includes protective side plates, columns, and crossbeams. The protective side plates are arranged in two sets and symmetrically attached to the side walls of the geotechnical foundation pit. The columns are arranged in several sets and fixed to the protective side plates at equal intervals by bolts. The crossbeams are arranged in several sets and located between the two symmetrical sets of columns. The protective components include a water collection tank, a pump body, a water delivery pipe, a water guide plate, and a protective plate. The water collection tank is located outside the soil foundation pit. The pump body is installed on the water collection tank. One end of the pump body is connected to the water collection tank through a water pipe, and the other end is connected to a water delivery pipe. The outer end of the water delivery pipe is connected to a water guide plate. The water guide plate is fixed to several sets of columns by bolts. Several sets of crossbeams are evenly installed between two sets of water guide plates. The water guide plate has a water guiding cavity inside and sealing plates are fixed at both ends. Both sets of sealing plates have openings. The water delivery pipe is connected to the opening of one set of sealing plates. The protective plate is installed at an angle on the edge of the water guide plate.

[0006] In a preferred embodiment of this utility model, the protective side plate is made of steel plate and its inclination is the same as the slope of the side wall of the soil foundation pit.

[0007] In a preferred embodiment of this utility model, the inclination of the column is the same as that of the protective side plate, and the column is made of steel and has the same height as the protective side plate.

[0008] In a preferred embodiment of this utility model, the water guiding cavity is opened at an angle, and the height of the water guiding cavity near one end of the water supply pipe is lower than the height of the other end.

[0009] In a preferred embodiment of this utility model, the distance between the lower end of the protective plate and the column is less than the distance between the upper end of the protective plate and the column, and the top height of the protective plate is greater than the top height of the soil foundation pit.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model improves the existing construction support structure for soil and rock foundation pits by equipping protective components on both sides of the support frame. These protective components can concentrate the water and sediment flowing down from both sides of the foundation pit, facilitating the external discharge of water and sediment and preventing water and sediment from entering the foundation pit. This improves the stability of the support structure and the safety of the foundation pit.

[0011] 2. The construction support structure for soil and rock foundation pits designed in this utility model can effectively prevent water and silt from entering the foundation pit from both sides, thereby improving the support effect and stability. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3 This utility model provides a technical solution: a foundation support structure for geotechnical construction, including a support frame and two sets of protective components installed on both sides of the support frame. The support frame is built into the geotechnical foundation pit and includes protective side plates 1, columns 2, and crossbeams 3. The protective side plates 1 are divided into two sets and symmetrically attached to the side walls of the geotechnical foundation pit. The columns 2 are divided into several sets and fixed to the protective side plates 1 at equal intervals by bolts. The crossbeams 3 are divided into several sets and located between the two symmetrical sets of columns 2. The protective components include a water collection tank 4, a pump body 5, a water delivery pipe 6, a water guide plate 7, and a protective plate 8. The water collection tank 4 is located outside the geotechnical foundation pit. On the side, the pump body 5 is installed on the water collection tank 4. One end of the pump body 5 is connected to the water collection tank 4 through a water pipe and the other end is connected to the water supply pipe 6. The outer end of the water supply pipe 6 is connected to the water guide plate 7. The water guide plate 7 is fixed to several sets of columns 2 by bolts. Several sets of crossbeams 3 are evenly installed between two sets of water guide plates 7. The water guide plate 7 has a water guide cavity 9 inside and sealing plates 10 are fixed at both ends. Both sets of sealing plates 10 have through holes 11. The water supply pipe 6 is connected to the through hole 11 of one set of sealing plates 10. The through hole 11 at the other end can be connected to a drainage pipe. The protective plate 8 is installed at an angle on the edge of the water guide plate 7.

[0016] Further improvements, such as Figure 2 As shown, the protective side plate 1 is made of steel plate and its inclination is the same as the slope of the side wall of the soil and rock foundation pit, so as to achieve the purpose of protecting the side wall of the soil and rock foundation pit.

[0017] Further improvements, such as Figure 2As shown, the inclination of column 2 is the same as that of protective side plate 1. Column 2 is made of steel and its height is the same as that of protective side plate 1, which can achieve the purpose of supporting and fixing protective side plate 1.

[0018] Further improvements, such as Figure 3 As shown, the water guiding channel 9 is opened at an angle, and the height of the water guiding channel 9 near the end of the water supply pipe 6 is lower than the height of the other end. This design facilitates the guidance and discharge of mud and water.

[0019] Specifically, the distance between the lower end of the protective plate 8 and the column 2 is less than the distance between the upper end of the protective plate 8 and the column 2, and the top height of the protective plate 8 is greater than the top height of the soil foundation pit. The protective plate 8 can effectively prevent the mud and sand on both sides of the foundation pit from entering the pit and concentrate the mud and sand and water in the water guiding cavity 9.

[0020] In use: The protective side plate 1, column 2 and beam 3 built into the soil foundation pit achieve the purpose of protecting and supporting the side wall of the foundation pit. In daily use, if rainy weather causes mud and water from the outside of the foundation pit to be poured into the foundation pit, the water and mud are concentrated through the water guide cavity 9 of the water guide plate 7, and the protective plate 8 is used to achieve the purpose of protection, so that the water and mud are better guided into the water guide plate 7. The water guided into the water guide plate 7 is discharged from the other end through the water guide cavity 9. When mud and sand fall into the water guide plate 7, the pump body 5 pumps the water in the water collection tank 4 and guides it into the water guide plate 7 through the water pipe 6 to flush the mud and sand in the water guide cavity 9, so as to facilitate better external discharge.
