Description

Technical Field

[0001] The present invention relates to an electrolytic desaturation cell and a construction method, and in particular to an intelligent electrolytic desaturation cell for liquefiable foundation and a construction method. Background Art

[0002] Liquefaction typically occurs when a highly saturated soil layer loses its stability due to vibrations and other disturbances during an earthquake. This causes the soil to lose its original support capacity and become fluid, leading to the collapse, subsidence, and lateral displacement of structures such as buildings, roads, and bridges. The consequences of soil liquefaction are extremely serious, resulting in significant loss of life and property. Therefore, the treatment of liquefiable foundations has become a research focus.

[0003] In recent years, new anti-liquefaction measures based on the electrolysis desaturation method have begun to be applied and invented. That is, by electrolyzing the soil to generate gas, the water in the soil is discharged, the saturation of the foundation is reduced, and the anti-liquefaction strength of the foundation is improved. However, the application of the existing electrolysis desaturation method has many shortcomings. For example, there are only a few prefabricated simple devices for the electrolysis desaturation method, and the application is relatively rough, which limits large-scale promotion and use. At the same time, the electrolysis process inside the soil will generate heat, and this heat will not only reduce the life of the equipment but also cause other unpredictable reactions in the soil, affecting the safety of the device. Finally, the use of existing electrolysis devices is also relatively complicated and not easy to construct, such as patent number: CN201520267825.X and other documents.

[0004] At the same time, plastic drainage board soft foundation treatment has been rapidly developed as a new soft foundation treatment and reinforcement technology due to its advantages such as good water filtration, low cost, small cross-section, small disturbance to the foundation during insertion, and lightweight installation machinery - board insertion machine, and has been widely used, such as patent number: CN202211271323.5 and other documents. However, its defects are also obvious, such as the lack of visible internal drainage effect, especially for deep drainage, and the uneven drainage effect. At the same time, although there are filter layers wrapped with non-woven fabrics on both sides, soil particles will still flow out from the bottom along the water flow, which will not only destroy the soil structure, but also may cause drainage channel blockage due to the influence of soil pressure in deep areas, which is difficult to detect. Summary of the Invention

[0005] Purpose of the invention: The purpose of the present invention is to provide an intelligent electrolysis desaturation battery cell and construction method for liquefiable foundations, so as to realize the intelligent, efficient, convenient and wide applicability of electrolysis desaturation applications.

[0006] Technical solution: The present invention includes a battery cell, and multiple battery cells are connected to form a battery cell roll. The battery cell includes multiple battery cell units, and the battery cell unit includes an electrolytic layer, a heat dissipation frame, a conductor and an intelligent device. The conductor and the intelligent device are arranged in the heat dissipation frame, and the electrolytic layer is wrapped on the outside of the heat dissipation frame. The intelligent device includes a detector, a pushing component and multiple groups of connectors. When the detector detects that the surrounding soil reaches a preset value, the pushing component is operated and the connectors are contacted and connected to perform electrolysis.

[0007] The pushing assembly includes a pusher and a conductive connection area. The pusher is located at the bottom of the detector. The bottom of the pusher is fixedly connected to the conductive connection area. The area where the conductive connection area and the pusher are connected is an insulating connection area.

[0008] The multiple groups of connectors are respectively arranged on both sides of the pusher, and each group includes an electrolytic layer contact point and a conductor contact point. Springs and wires are respectively connected between the electrolytic layer contact points and the conductive connection areas on both sides of the pusher. When the connector is not triggered, the displacement is limited by the spring to remain stationary.

[0009] The conductor contact point is located below the conductive connection area.

[0010] The heat dissipation frame includes a soft frame and a hard frame. The soft frame is used to place conductors. The hard frame is embedded in the soft frame and is used to place smart devices.

[0011] The electrolytic layer contact points and the conductor contact points are both embedded in the hard frame and keep in contact with the electrolytic layer and the conductor respectively.

[0012] The electrolytic layer includes a positive electrolytic layer and a negative electrolytic layer. The electrolytic area ratio of the positive and negative electrolytic layers is 2:1, and the electrolytic layers are separated by insulating coatings or materials and do not contact each other.

[0013] The electrolytic layer is wrapped with a binding layer to prevent the electrolytic layer from being worn and to prevent the battery cells from being assembled and integrated.

[0014] The end of the battery cell is provided with a connection area, which includes a non-cutting area and a cutting area. A plurality of battery cells are connected through the connection area to form a battery cell roll, which is convenient for transportation and construction.

[0015] A construction step applicable to the above-mentioned intelligent electrolysis desaturation cell for liquefiable foundation includes:

[0016] (1) Design the construction location and complete the preliminary construction work;

[0022] Beneficial effects: The present invention utilizes the core idea of ​​intelligent layered electrolysis to realize the application of electrolysis desaturation in regional electrolysis, so that the desaturation effect of each region in the depth direction is good and evenly distributed, which not only reduces energy consumption but also improves the desaturation effect; the intelligent device of the present invention controls the switch of the electrolysis branch in each region, making the electrolysis in each region intelligent, and enhancing the controllability and stability of regional electrolysis desaturation; the present invention improves the wire originally placed inside the soil into a conductor built into the heat dissipation soft frame of the device, which not only protects the various circuits of the device, but also reduces heat accumulation, ensuring the energy saving, safety and durability of the device; the present invention draws on the plastic drainage board for treating liquefiable foundations, and innovatively designs the concept of flexible battery cells.

[0035] The present invention will be further described below with reference to the accompanying drawings.

[0036] like Figure 1 and Figure 2 As shown, the battery cell unit 7 of the present invention includes a binding layer 1, an electrolyte layer, a heat dissipation frame 4, a conductor 5, and an intelligent device 6. The electrolyte layer includes a positive electrolyte layer 3 and a negative electrolyte layer 2. The electrolyte areas of the positive and negative electrolyte layers are in a 2:1 ratio. The positive and negative electrolyte layers are separated by an insulating material. In this embodiment, the arrangement is with the negative electrolyte layer 2 on top and the positive electrolyte layer 3 on the bottom. Alternatively, the arrangement can be with the positive electrolyte layer 3 on top and the negative electrolyte layer 2 on the bottom. The conductor 5 and the intelligent device 6 are disposed within the heat dissipation frame 4. Two conductors 5 are provided, independently disposed within the heat dissipation frame 4, and connected to the positive and negative poles of the power supply via upper end contacts. The electrolyte layer is wrapped around the outside of the heat dissipation frame 4, and the binding layer 1 is wrapped around the electrolyte layer. The binding layer 1 is used to prevent wear of the electrolyte layer and to integrate the battery cells. The binding layer 1 is made of a water-permeable material that can prevent soil particles from entering the device, such as a fiber material such as a non-woven fabric.

[0037] A plurality of battery cells 7 are bound together by a binding layer 1 to form a battery cell 8. The plurality of battery cells 7 are connected in parallel circuits. The battery cell 7 is the smallest unit that maintains the normal operation of the battery cell 8. The plurality of battery cells 7 are bound together to form a battery cell 8. A connection area is provided at the end of the battery cell 8 for connecting to the next battery cell 8. The connection area includes a non-cutting area 102 and a cutting area 103. The non-cutting area 102 is used to protect the end of the battery cell 8. The cutting area 103 is a binding layer extending out of the end of the battery cell 8. Figure 3 and Figure 4 The battery cell 8 is a construction unit driven into the ground during construction. Several battery cells 8 are connected through the connection area to form a battery cell roll 9, which is convenient for transportation and construction. Figure 5 The battery cell roll 9 is used in the construction. When the construction of one battery cell 8 is completed, the cutting can be completed in the cutting area 103 and the construction of the next battery cell 8 can be turned to.

[0038] like Figure 6 As shown, when the branch circuit is connected, the pusher 602 in the smart device pushes the conductive connection area 604 until the conductive connection area 604 contacts the conductor contact point 608, and the branch circuit is connected.

[0039] like Figure 7 As shown, when the branch circuit is disconnected, the conductive connection area 604 in the smart device is not in contact with the conductor contact point 608, and the spring 606 pulls up the conductive connection area 604 to reset it.

[0040] like Figure 8 As shown, the heat dissipation frame 4 is made of insulating and thermally conductive materials and can be covered with heat dissipation material to provide protection, insulation, and heat dissipation. It comprises a soft frame 402 and a hard frame 401, which are tightly connected to form a single unit. The soft frame 402 houses the conductors 5, while the hard frame 401 is embedded within the soft frame 402 and houses the smart device 6. The conductors 5 are separated by the heat dissipation frame 4, making them independent and allowing for connection to the positive and negative terminals of a power source via wires.

[0041] like Figures 9 to 11 As shown, intelligent device 6 includes a detector 601, a pusher 602, and a connector. The bottom of detector 601 is connected to pusher 602, which is fixedly connected to a conductive connection area 604. The area where conductive connection area 604 and pusher 602 connect is an insulated connection area 603. Detector 601 requires a preset threshold value and acts as a control. Pusher 602 switches on and off based on the signal from detector 601, allowing single-axis movement within a certain range.

[0042] In this embodiment, there are two groups of connectors, which are symmetrically arranged on both sides of the pusher 602. Each group includes an electrolytic layer contact point 605 and a conductor contact point 608. The conductor contact point 608 is located below the conductive connection area 604. The electrolytic layer contact point 605 and the conductor contact point 608 are both embedded in the hard frame 401 and maintain good contact with the electrolytic layer and the conductor 5 respectively. Springs 606 and wires 607 are respectively connected between the electrolytic layer contact points 605 and the conductive connection area 604 on both sides of the pusher 602. When the connector is not triggered, the spring 606 limits the displacement and keeps it stationary. At this time, the conductive connection area 604 and the conductor contact point 608 are in a separated state. When the detector 601 detects that the surrounding soil reaches a preset value, the pusher 602 starts, driving the conductive connection area 604 to move and contact and connect with the conductor contact point 608; when the detector does not reach the preset value, the pusher 602 is closed. At this time, the spring 606 pulls the conductive connection area 604 back to its original position and disconnects it.

[0043] like Figure 9As shown, the electrolyte layer contact points 605 on both sides are semicircular or have other contact surfaces, and only contact the electrolyte layer to be connected. In this embodiment, the negative electrolyte layer 2 is arranged above the positive electrolyte layer 3. Therefore, the electrolyte layer contact point 605 connecting to the positive electrolyte layer 3 is in the lower semicircular shape, and the other side connecting to the negative electrolyte layer 2 is in the upper semicircular shape. If the positions of the positive and negative electrolyte layers are swapped, only the above-mentioned electrolyte layer contact points need to be adjusted accordingly. Conductor contact points 608 are connected to the conductors 5 on the left and right sides. When the conductors 5 are powered on and the surrounding soil moisture reaches the preset value of the detector 601, a branch circuit in the parallel main circuit is connected, and electrolysis begins.

[0044] like Figure 12 As shown, after the construction steps are completed, the battery cell 8 will be arranged in the middle of four ordinary plastic drainage boards to form a working area; when the battery cell 8 is electrolyzed to form a desaturated area, due to the presence of the surrounding ordinary plastic drainage boards, a good infiltration channel is provided for the internal seepage of the soil, and the desaturated area tends to expand outward, while promoting the drainage of the surrounding soil and improving the drainage effect of the ordinary plastic drainage boards. In addition, the intelligent electrolytic battery cell arranged in the middle of the four ordinary plastic drainage boards can play a role in controlling and regulating the saturation of the area and the water level inside the surrounding soil.

[0045] The construction steps of the present invention include:

[0046] (a) Pre-design the construction scope and the location where the smart cell needs to be installed;

[0047] (b) Clean the working surface and lay a sand cushion layer;

[0048] (c) Move and position the board inserting machine and complete the installation and sand filling of ordinary plastic drainage boards in each work area according to the designated position;

[0049] (d) Reposition the plate inserter and pass the cell roll through the guide tube. After the plate inserter is accurately positioned, install the sheet pile shoe.

[0050] (e) Sink the guide tube and drive the battery cells to the designed elevation;

[0051] (f) Pull up the conduit until the bottom of the conduit is about 50 cm above the sand cushion;

[0052] (g) Cutting in the cuttable area of ​​the cell roll to complete the construction of one cell;

[0053] (h) Backfill the gaps between the plug-in boards with sand and fill in the pits formed during construction. At the same time, the battery cells should be straightened;

[0054] (i) Repeat the above steps to complete the construction of the battery cells in the construction area;

[0055] (j) The electrodes are connected, and then the smart cell performs intelligent layered electrolysis based on the surrounding soil conditions.
