Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a reinforcement structure for a silt foundation. Background Technique

[0002] A silt foundation refers to a highly compressible soft foundation composed of silt and silty soil. Usually, silty soil is generally distributed in areas close to river channels or areas with rich groundwater systems. When carrying out engineering construction on the above silty soil, it is often necessary to construct a foundation reinforcement structure to reduce settlement, or even if settlement occurs, make the settlement more uniform everywhere on the foundation.

[0003] In the prior art, the silt foundation is generally reinforced by excavating the silt and backfilling dry sand. However, if the above method is used in areas with developed groundwater systems, the backfilled dry sand is in direct contact with the soft soil, and there is still a risk of being soaked and forming soft soil or silt. Since silt has fluidity, it will cause the building to sink.

[0004] Based on this, this application proposes a reinforcement structure for a silt foundation to solve the above technical problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a reinforcement structure for a silt foundation to solve the technical problem that in the prior art, the silt foundation is reinforced by backfilling dry sand, but the backfilled dry sand is in direct contact with the soft soil, and there is still a risk of being soaked and forming soft soil or silt. Since silt has fluidity, it will cause the building to sink as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0009] There are multiple support piles, and the multiple support piles are distributed in the main frame in an array, and the top of the support pile is connected to the bottom of the load-bearing plate, and the bottom of the support pile extends below the connecting plate;

[0010] The support net is arranged between the grid plate and the connecting plate, the top of the support net is connected to the bottom of the grid plate, and the bottom of the support net is connected to the top of the connecting plate.

[0011] As a preferred solution, the support net includes a plurality of horizontal support bars and a plurality of vertical support bars, and the plurality of horizontal support bars and the plurality of vertical support bars are vertically connected to form a net structure.

[0012] As a preferred solution, both the horizontal support bars and the vertical support bars include a plurality of inverted V structures, and the plurality of inverted V structures are sequentially connected to form protrusions and depressions distributed at intervals.

[0013] As a preferred solution, the connecting plate includes a plurality of horizontal plates and a plurality of vertical plates, the horizontal plates are vertically connected to the vertical plates, and the supporting ground pile is vertically arranged at the connection of the horizontal plates and the vertical plates.

[0014] As a preferred solution, a cone is provided at the bottom of the supporting ground pile, and the cone is located below the connecting plate.

[0015] It can be seen from the technical solution provided by the present utility model described above that a sludge foundation reinforcement structure provided by the present utility model, compared with the prior art, has the beneficial effects that:

[0016] 1. When the present application is provided with a support net in the gravel layer, through the barrier of the gravel layer and the support net, the fluidity of the wetted backfill dry sand in the gravel layer is effectively slowed down, achieving the effect of slowing down the settlement of the building;

By increasing the contact area between the building and the underlying soil layer through the reinforcement structure, the settlement speed of the building is slowed down.

[0029] In order to better understand the above technical solutions, the above technical solutions will be described in detail below with reference to the specification drawings and specific implementation manners

[0030] Please refer to Figures 1 to 6, an embodiment of the present application provides a silt foundation reinforcement structure, including: a main frame 1, support piles 2 and a support mesh 3; a connecting plate 4 is provided at the bottom of the main frame 1, a load-bearing plate 5 is provided at the top of the main frame 1, a grid plate 6 is provided between the connecting plate 4 and the load-bearing plate 5, a backfill layer 7 is filled between the load-bearing plate 5 and the grid plate 6, and a gravel layer 8 is filled between the grid plate 6 and the connecting plate 4; multiple support piles 2 are provided, and the multiple support piles 2 are arranged in an array within the main frame 1, and the top of the support pile 2 is connected to the bottom of the load-bearing plate 5, and the bottom of the support pile 2 extends below the connecting plate 4; the support mesh 3 is arranged between the grid plate 6 and the connecting plate 4, the top of the support mesh 3 is connected to the bottom of the grid plate 6, and the bottom of the support mesh 3 is connected to the top of the connecting plate 4.

[0031] Further, the backfill layer 7 can be filled with backfill dry sand.

[0032] Further, the load-bearing plate 5 can be made of concrete material.

[0033] Further, the support mesh 3 can be made of steel material.

[0034] The structure of the present application is provided with a support mesh 3 in the gravel layer 8. When in an area with a developed groundwater system, the load-bearing plate 5 is pressed down, causing the silt below the connecting plate 4 to be compressed, resulting in the water in the silt passing through the gravel layer and contacting the backfill layer. Through the barrier of the gravel layer 8 and the support mesh 3, the fluidity of the wetted backfill dry sand in the gravel layer is effectively slowed down, achieving the effect of slowing down the settlement of the building.

[0035] Further, the present application uses the connecting plate 4, the grid plate 6 and the load-bearing plate 5 to divide the silt foundation reinforcement structure into a double-layer structure. First, the connecting plate 4 is in direct contact with the soft soil of the foundation. The support piles 2 are fixed on the connecting plate 4, so that the bottom of the support piles 2 is inserted into the soft soil below the connecting plate 4. The support mesh 3 is erected on the connecting plate 4, and the space above the connecting plate 4 is filled with gravel; then, the grid plate 6 is installed on the gravel layer 8, the grid plate 6 is fixedly connected to the support piles 2, and the backfill layer 7 (backfill dry sand) is filled on the grid plate 6; finally, the load-bearing plate 5 is arranged on the top of the backfill layer 7, and the load-bearing plate 5 is pressed down to compact the backfill layer 7. The backfill dry sand in the backfill layer 7 can enter the gravel layer 8 through the pores on the grid plate 6, so that the backfill layer 7, the grid plate 6 and the gravel layer 8 are mixed to reinforce the silt foundation. By increasing the contact area between the building and the underlying soil layer through the reinforcement structure, the settlement speed of the building is slowed down.

[0036] Further, using the gravel layer 8 can improve the bearing capacity of the silt foundation, using the support mesh 3 can improve the compressive effect of the silt foundation, and using the load-bearing plate 5 can protect the structure below the load-bearing plate 5.

[0037] In one embodiment, as Figure 6As shown, the support net 3 includes a plurality of transverse support bars 31 and a plurality of vertical support bars 32. The plurality of transverse support bars 31 and the plurality of vertical support bars 32 are perpendicularly connected to form a net structure, which improves the compressive effect of the silt foundation.

[0038] In one embodiment, as Figure 5 or Figure 6 shown, both the transverse support bar 31 and the vertical support bar 32 include a plurality of inverted V structures. The plurality of inverted V structures are sequentially connected to form protrusions 33 and depressions 34 that are spaced apart. When the transverse support bar 31 is perpendicularly connected to the vertical support bar 32, the protrusions 33 of the transverse support bar 31 are correspondingly connected to the protrusions 33 of the vertical support bar 32 to form a three-dimensional net structure, which slows down the fluidity of the gravel layer and enhances the structural strength at the same time.

[0039] In one embodiment, as Figure 2 shown, the connecting plate 4 includes a plurality of horizontal plates and a plurality of vertical plates. The horizontal plates and the vertical plates are perpendicularly connected, and the support pile 2 is vertically arranged at the connection of the horizontal plates and the vertical plates. The connecting plate 4 can be made of steel or concrete, which is convenient for fixing the support pile 2 and provides support for the support pile 2.

[0040] In one embodiment, as Figure 4 shown, the bottom of the support pile 2 is provided with a cone 21, and the cone 21 is located below the connecting plate 4. The bottom of the support pile 2 is set as the cone 21 to facilitate insertion into the soft soil below.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
