Technical Field
[0001] This utility model belongs to the field of geotechnical engineering technology, specifically relating to a surcharge device for treating soft soil foundations. Background Technology
[0002] In recent years, a large number of construction projects have been carried out in the relatively economically developed southeastern coastal areas of my country. These areas are characterized by deep soft soil foundations (high water content silty soft soil or dredged fill), with some projects having soft soil layers (layers to be treated) that are more than 20 meters thick. Foundation treatment is necessary before construction. Conventional methods for treating deep soft soil foundations include vacuum preloading, surcharge preloading, or a combination of vacuum and surcharge preloading. However, these methods still have the following drawbacks:
[0003] In practical applications, the treatment of deep soft soil foundations often faces challenges such as long treatment time, poor treatment effect, and poor drainage effect.
[0004] Therefore, we have made improvements to this by proposing a surcharge device for handling soft soil foundations. Utility Model Content
[0005] The purpose of this invention is to provide a surcharge device for treating soft soil foundations, so as to solve the technical problems of long treatment time, poor treatment effect and poor drainage effect often encountered when treating deep soft soil foundations, and to improve the consolidation efficiency of soft soil foundations.
[0006] To solve the above-mentioned technical problems, this utility model provides a surcharge device for treating soft soil foundations, including a sand cushion layer laid on top of the soft soil foundation, a drainage component provided on the sand cushion layer, and a surcharge component provided on the drainage component.
[0007] The drainage assembly includes a water pump, a pumping pipe, a drain pipe, a soil cushion layer, a diversion pipe, a diversion chamber, and drainage boards. The water pump is located on top of the sand cushion layer. The pumping pipe is fixedly connected to the pumping end of the water pump. The drain pipe is fixedly installed on the draining end of the water pump. The soil cushion layer is laid on top of the sand cushion layer and buries the pumping pipe. Multiple diversion pipes are installed on the pumping pipe and extend into the soft soil foundation. The diversion chamber is fixedly installed at the end of the diversion pipe away from the pumping pipe. Multiple drainage boards are installed on the diversion chamber.
[0008] Furthermore, the surcharge assembly includes precast concrete blocks, connecting slots, and connecting plugs. A plurality of the precast concrete blocks are disposed on the top of the soil cushion layer. The connecting slots are opened at one end of the precast concrete blocks, and the connecting plugs are fixed to the other end of the precast concrete blocks and are used in conjunction with the connecting slots.
[0009] Furthermore, the precast concrete block is provided with a water filling chamber inside, and the water filling chamber is provided with a water-absorbing block inside.
[0010] Furthermore, a protective cover is installed at the water inlet of the water tank to prevent leakage of water from inside the water tank.
[0011] Furthermore, the bottom of the precast concrete block is provided with multiple splicing grooves, and the top of the precast concrete block is fixedly connected with multiple splicing blocks, which are used to cooperate with the splicing grooves for insertion.
[0012] Furthermore, one side of the drainage board is provided with multiple rows of water-absorbing protrusions.
[0013] Furthermore, a pore water pressure sensor and a settlement monitoring instrument for real-time monitoring of foundation consolidation parameters are installed on the sand cushion layer.
[0014] The beneficial effects of this utility model are:
[0015] 1. By setting up drainage components, the drainage board can absorb the moisture contained in the soft soil foundation during use. Excess moisture will flow through the drainage board into the diversion chamber. Then, the water pump can be started to extract the moisture from the multiple diversion chambers, thereby draining the moisture from the soft soil foundation and improving the consolidation efficiency of the soft soil foundation.
[0016] 2. By setting up a stacking assembly, a water tank, and water-absorbing blocks, multiple precast concrete blocks can be spliced together for stacking during use through connecting slots and connecting blocks. Then, water is injected into the water-absorbing blocks through the water tank to change their self-weight, achieving staged loading. This allows for more precise control of the loading amount, avoiding overload or underload, while reducing construction steps and improving efficiency.

[0026] Example:
[0027] like Figure 1-4 As shown, a surcharge device for treating soft soil foundation includes a sand cushion layer 1 laid on top of the soft soil foundation, a drainage component 2 disposed on the sand cushion layer 1, and a surcharge component 3 disposed on the drainage component 2.
[0028] like Figure 3As shown, the drainage assembly 2 includes a water pump 201, a pumping pipe 202, a drain pipe 203, a soil cushion layer 204, a diversion pipe 205, a diversion chamber 206, and drainage boards 207. The water pump 201 is located on top of the sand cushion layer 1. The pumping pipe 202 is fixedly connected to the pumping end of the water pump 201. The drain pipe 203 is fixedly installed on the draining end of the water pump 201. The soil cushion layer 204 is laid on top of the sand cushion layer 1 and buries the pumping pipe 202. Multiple diversion pipes 205 are located on the pumping pipe 202 and extend into the soft soil foundation. The diversion chamber 206 is fixedly installed at the end of the diversion pipe 205 away from the pumping pipe 202. Multiple drainage boards 207 are installed on the diversion chamber 206. When in use, the drainage board 207 can absorb the moisture contained in the soft soil foundation. Excess moisture will flow through the drainage board 207 into the diversion chamber 206. Then, the water pump 201 is started to extract the moisture from the multiple diversion chambers 206, thereby draining the moisture from the soft soil foundation and improving the consolidation efficiency of the soft soil foundation.
[0029] like Figure 3 As shown, the surcharge assembly 3 includes precast concrete blocks 301, connecting slots 302, and connecting blocks 303. Multiple precast concrete blocks 301 are disposed on top of the soil cushion layer 204. The connecting slots 302 are located at one end of each precast concrete block 301, and the connecting blocks 303 are fixed to the other end of each precast concrete block 301 and are inserted into the connecting slots 302. In use, multiple precast concrete blocks 301 can be joined together for surcharge via the connecting slots 302 and connecting blocks 303.
[0030] like Figure 3 As shown, the precast concrete block 301 has a water filling chamber 4 inside, and a water-absorbing block 5 inside the water filling chamber 4. During use, water is injected into the water-absorbing block 5 through the water filling chamber 4 to change its weight, thereby achieving staged loading. This allows for more precise control of the loading amount, avoiding overloading or underloading, while also reducing construction steps and improving efficiency.
[0031] like Figure 3 As shown, a protective cover 6 is installed at the water inlet of the water tank 4 to prevent leakage of water from the inside of the water tank 4. During use, the protective cover 6 prevents leakage of water from the inside of the water tank 4.
[0032] like Figure 3 As shown, the bottom of the precast concrete block 301 has multiple splicing slots 7, and the top of the precast concrete block 301 is fixedly connected to multiple splicing blocks 8, which are used to interlock with the splicing slots 7. In use, the splicing slots 7 and splicing blocks 8 can facilitate the stacking of multiple precast concrete blocks 301.
[0033] like Figure 3As shown, the drainage board 207 has multiple rows of absorbent ridges 9 on one side. During use, the absorbent ridges 9 can increase the interlocking effect between the drainage board 207 and the soil, improve drainage efficiency, accelerate the consolidation of soft soil, shorten the construction period, and improve the structural stability of the drainage board 207.
[0034] like Figure 3 As shown, a pore water pressure sensor 10 and a settlement monitoring instrument 11 for real-time monitoring of foundation consolidation parameters are installed on the sand cushion layer 1. In use, the pore water pressure sensor 10 and the settlement monitoring instrument 11 can monitor the foundation consolidation parameters in real time.
[0035] In summary, when using this surcharge device for treating soft soil foundations: the drainage board 207 absorbs the moisture contained within the soft soil foundation, and excess moisture flows through the drainage board 207 into the diversion chamber 206. Then, the water pump 201 is activated to extract the moisture from the multiple diversion chambers 206, thereby draining the moisture from the soft soil foundation and improving the consolidation efficiency. Multiple precast concrete blocks 301 can be spliced together for surcharge through connecting slots 302 and connecting inserts 303. Then, water is injected into the water-absorbing blocks 5 through the water filling chamber 4 to change their self-weight, achieving graded loading. This allows for more precise control of the loading amount, avoiding overloading or underloading, while also reducing construction steps and improving efficiency.
