Description

Technical Field

[0001] The present invention relates to a method for collecting and draining soil and a negative pressure collecting and draining structure, belonging to the technical field of drainage. Background Art

[0002] Chinese Patent (Publication No.: CN220468524U) discloses a three-dimensional composite drainage mat with a water and gas pipeline, which at least includes a first drainage body and a second drainage body; a part or all of the first drainage body is a convex structure; the convex structure cooperates with the wall surface of the second drainage body to form a pipeline capable of flowing water and gas; the second drainage body is fixedly connected with the first drainage body to form a three-dimensional composite drainage mat with a water and gas pipeline.

[0003] The above solution sets the first drainage body and the second drainage body with convex structures, and the convex structure cooperates with the wall surface of the second drainage body to form a pipeline capable of flowing water and gas. However, the pipelines are independently arranged, resulting in the inability to converge the moisture and gas in the soil together when actually applying the three-dimensional composite drainage mat, and they can only flow in the corresponding pipelines. Therefore, it is impossible to collect and drain water and exhaust gas, which affects the drainage efficiency, further prolongs the foundation construction time, and is not conducive to popularization and use.

[0004] Furthermore, the above solution and the prior art do not disclose how to collect and drain water, which further affects the drainage efficiency and leads to longer foundation construction times for various types of foundations.

[0005] The information disclosed in this background art is only used to understand the background of the inventive concept of the present invention, so it may include information that does not constitute prior art. Summary of the Invention

[0109] In this embodiment: The method for laying horizontal drainage plates on the soil surface for horizontal drainage or drainage gas is as follows:

[0110] The horizontal drainage plates include a number of transverse drainage plates and a number of longitudinal drainage plates;

[0111] The spacing distance between the horizontal drainage plates is 300 mm to 1500 mm;

[0112] The spacing distance between the vertical drainage plates is 300 mm to 1500 mm;

[0113] A number of horizontal drainage plates and a number of vertical drainage plates are laid horizontally and vertically, or laid in a criss-cross laminated manner, or laid in an overlapping and lapping manner, for horizontal drainage or drainage of water and gas;

[0114] The number of the vertical drainage plates is multiple, and the spacing distance therebetween is 100 mm to 150 mm.

[0115] As Figures 1-4 shown, the first specific embodiment of the negative pressure collecting and draining structure of the present invention:

[0116] A negative pressure collecting and draining structure includes a plate for changing the water flow direction, a drainage channel for guiding drainage, and a filter for filtering water or / and gas in the soil; the plate, the drainage channel and the filter are assembled together in sequence to form the negative pressure collecting and draining structure, and the negative pressure collecting and draining structure can enable water or / and gas in the soil to penetrate from the filter into the drainage channel, and under the limitation of the plate, can perform collecting drainage or drainage of water and gas. The filter directly filters water or / and gas in the soil; or, the filter filters water or / and gas in the soil through a composite drainage structure.

[0117] In this embodiment: the plate is a plastic plate 1, which is encapsulated with the filter to form a semi-closed water and gas cavity.

[0118] In this embodiment: the semi-closed water cavity communicates with a drain pipe 4, and a driving source is assembled on the drain pipe 4, and the driving source is a vacuum pump.

[0119] The drain pipe 4 is of an inverted L-shaped structure, one end port of which can extend to the outside of the soil, and the driving source is assembled at this port, and the other port thereof is welded to the opening on the plastic plate 1 to form a negative pressure suction structure, so as to improve the negative pressure suction intensity and suction efficiency; the drain pipe 4 is a plastic drain pipe, and its cross section is circular.

[0120] In this embodiment: the drainage channel is one or more layers of plastic geogrids 2, which are assembled between the plate and the filter as a drainage channel. The plastic geogrid 2 includes a number of horizontally and vertically arranged plastic strips 21, with simple and practical structure and low manufacturing cost.

[0121] In this embodiment: the filter is a high-strength permeable fiber filter cloth 3, which is laid in one or more layers, and the edge thereof is welded and sealed with the edge of the plate, so that the welded area at the joint of the two is large and the sealing is firm and reliable.

[0122] The high-strength permeable fiber filter cloth 3 is polyester fiber filter cloth 3, or polypropylene fiber filter cloth 3, or nylon fiber filter cloth 3, or vinylon fiber filter cloth 3, or cotton woven filter cloth, or fiberglass filter cloth.

[0123] In this embodiment, an electronic microwave sounding drainage board can be used to inspect the construction depth, and the deviation range between the measurement accuracy and the actual measured depth is controlled within 20 cm, and the sampling rate for construction quality acceptance is not less than 10%.

[0124] The sounding drainage board is provided with a wire for electronic microwave sounding and a printed digital scale mark. The sounding technology is beneficial to ensuring the authenticity of the construction process data and improving and perfecting the means of supervision and quality management in the engineering construction process. After the on-site drainage board construction is completed, a third-party quality inspection unit can be entrusted to randomly sample the actual construction depth at a frequency of 10% of the total number of drainage boards. The electronic sounding instrument used for detection needs to be calibrated. If there is any doubt about the construction depth of the drainage board, the sampling frequency and scope can be increased.

[0125] The second specific embodiment of the negative pressure flow-accumulating drainage structure of the present invention:

[0126] A negative pressure flow-accumulating drainage structure includes a plate, a drainage channel, and a filter element;

[0127] The plate is a plastic plate 1; the drainage channel is one or more layers of plastic geogrid 2; the filter element is a fiber filter cloth 3;

[0128] The plastic plate 1, the plastic geogrid, and the fiber filter cloth 3 are stacked and welded together in sequence to form a semi-closed water and gas cavity.

[0129] The semi-closed water cavity communicates with a drain pipe 4;

[0130] The drain pipe 4 is an inverted L-shaped structure, one end of which can extend outside the soil, and a driving source is assembled at this port, and the other end is welded to the opening on the plastic plate 1 to form a negative pressure suction structure, so as to improve the negative pressure suction intensity and suction efficiency, and then quickly discharge the water and gas in the soil to the ground, thereby compressing the soil, increasing the soil density, changing the compressive strength of the soil body, and reducing the compression deformation amount.

[0131] In this embodiment: the thickness of the plastic plate 1 is 1-5 mm, its width is 0.5-3 m, and it is located in the upper layer; the plastic geogrid 2 is located in the middle layer as a drainage channel, and the lower layer is the fiber filter cloth 3. The three materials are compounded into a negative pressure flow-accumulating drainage structure through a pressing strip and melting edge, so that the suction area of the negative pressure flow-accumulating drainage structure can reach 1-4 square meters, and the shape of the negative pressure flow-accumulating drainage structure is a circular structure, or a square structure, or a triangular structure, or an arc structure.

[0132] In this embodiment, the filter element is integrally formed by fusion welding with the plastic sheet 1 and the plastic geomesh edge pressing, making the filter element not easy to crack, the corner edges not easy to be damaged by friction, and the plastic sheet 1 and the plastic geomesh not easy to break, ensuring the water permeability of the drainage board.

[0133] At the same time, the integral drainage structure avoids the reverse tooth phenomenon caused by the shrinkage of the core board edge during the production of traditional drainage boards, ensuring the water permeability of the drainage board.

[0134] Furthermore, the 1.5m wide drainage board of the present invention can produce horizontal drainage boards of different widths by using the slitting technology, which can replace the horizontal drainage function of the sand cushion layer. At the same time, it has the functions of geogrid reinforcement and geotextile filtration, and can improve the water permeability rate of the filter element of the drainage board, reduce the seepage resistance, increase the seepage flow rate, making it easy for water and gas to be discharged from various soft and hard soil bases. Therefore, the water content in the soil can be continuously reduced, the degree of consolidation can be continuously improved, and the strength can be continuously increased. Furthermore, the foundation settlement and uneven settlement can be gradually eliminated to meet the use requirements of engineering projects such as land, marine engineering, and sewage environment.

[0135] As Figures 5-6 shown, the third specific embodiment of the negative pressure flow - collecting drainage structure of the present invention:

[0136] A negative pressure flow - collecting drainage structure is mainly composed of a plastic sheet 1, a plastic mesh board interlayer, and a filter element laminated strip edge - fused and compounded.

[0137] The upper layer of this component is a 2 - mm - thick plastic sheet 1, which provides a solid foundation for the whole component; the middle layer is interposed with a plastic geomesh 2 as a drainage channel for subsequent drainage work; and the high - strength permeable fiber filter cloth 3 used in the lower layer is used to filter debris in the soil, thus effectively avoiding the problem of blockage at the port of the drain pipe 4. Therefore, it can effectively improve the suction efficiency, reduce the resistance, and increase the drainage flow rate. The plastic geomesh includes several plastic strips arranged horizontally and vertically, and several plastic strips cross - lap to form a grid drainage structure. Therefore, it can effectively improve the efficiency of vacuum preloading drainage consolidation, shorten the drainage time required for various soft and hard soil bases, and thus shorten the construction period of the whole project.

[0138] In this embodiment, at the central position of the upper - layer plastic sheet 1, a take - port is designed for fusion welding with the port of the plastic drain pipe, forming an integrated connection structure, thereby significantly expanding the area of the suction port of the drain pipe 4 to reach 1 - 2.25 square meters, effectively enhancing the negative pressure suction intensity and also achieving a qualitative leap in the suction efficiency.

[0139] Meanwhile, to ensure the sealing effect, the interface between the flat layer of the plastic sheet 1 and the filter element is also welded and sealed, making the sealing effect more firm and reliable, providing a solid guarantee for the entire drainage process.

[0140] As Figures 7-8 shown, the fourth specific embodiment of the negative pressure collecting and draining structure of the present invention:

[0141] A negative pressure collecting and draining structure includes a sheet for limiting the flow direction of water or / and gas, a drainage channel for draining water or / and gas, and a filter element for filtering water or / and gas in the soil; the sheet, the drainage channel and the filter element are assembled together in sequence to form a negative pressure collecting and draining structure, and the negative pressure collecting and draining structure can make water or / and gas in the soil penetrate from the filter element into the drainage channel, and under the limitation of the sheet, can perform collecting and draining or draining gas. The sheet is provided with a plurality of long strips 11, and each long strip 11 extends outward along the central position of the sheet to form a radial arrangement structure.

[0142] As Figures 9-10 shown, the fifth specific embodiment of the negative pressure collecting and draining structure of the present invention:

[0143] A negative pressure collecting and draining structure includes a sheet for limiting the flow direction of water or / and gas, a drainage channel for draining water or / and gas, and a filter element for filtering water or / and gas in the soil.
