Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of soft foundation reinforcement processing devices, and particularly relates to a degradable drainage board for a large drainage channel. Background Art
[0002] The vacuum preloading method is a soft soil foundation consolidation treatment technology commonly used in geotechnical engineering. A vertical drainage device is inserted into the soft foundation, and the water in the soft foundation is drained using the vacuum negative pressure principle to reinforce the soft foundation into foundation soil with a certain strength and bearing capacity.
[0003] The most widely used vertical drainage device in the existing technology is plastic drainage board, which has the advantages of low cost, fast construction and good water permeability. Figure 1 As shown, it consists of a plastic core board and a permeable non-woven fabric wrapped around the outer periphery of the plastic core board. The core board includes a base board and a plurality of side boards arranged on both sides of the base board along the length direction of the base board, thereby providing a plurality of rectangular grooves on both sides of the core board, forming a plurality of vertical drainage channels. Although this type of drainage channel has the advantages of good shape stability and is suitable for the coating process requirements of the non-woven fabric by sewing the overlaps with a sewing machine and bonding the overlaps with an adhesive, its disadvantage is that the effective working area of the drainage channel is small and the phenomenon of clogging by fine soil particles often occurs, resulting in low drainage efficiency. In addition, traditional plastic drainage boards are made of non-degradable plastics. After being inserted into the ground, they cannot be degraded and will pollute the environment. Moreover, for soft foundation reinforcement, as long as the drainage board remains in the foundation, there will always be a drainage consolidation process, which is easy to cause post-construction foundation settlement.

[0034] refer to Figure 2-Figure 7 As shown, the present invention provides a biodegradable drainage board with a large drainage channel, which is used as a vertical drainage device when reinforcing soft foundations using the vacuum preloading method. The biodegradable drainage board with a large drainage channel includes a core panel 10 and a permeable filter cloth 20 wrapped around the core panel 10. The core panel 10 includes a main panel 11, two side panels 12, and multiple rib panels 13.
[0035] The main body panel 11 includes a plurality of first panels 111 and a plurality of second panels 112. The plurality of first panels 111 are arranged in one horizontal row, and the plurality of second panels 112 are arranged in another horizontal row. There is a gap between each pair of adjacent first panels 111, and there is also a gap between each pair of adjacent second panels 112. Each gap between the first panels 111 corresponds to a second panel 112 in the longitudinal direction, and each gap between the second panels 112 corresponds to a first panel 111 in the longitudinal direction. As a result, the first panels 111 and the second panels 112 in the two horizontal rows are staggered. A side panel 113 is connected between the adjacent ends of the first panels 111 and the second panels 112, thereby making the entire cross-section of the main body panel 11 corrugated. The horizontal length of the corrugated main body panel 11 can be flexibly set according to actual conditions.
[0036] One end of the two side panels 12 is respectively connected to the outermost end of the main body panel 11 in the transverse direction, and the other end extends to be flush with the first panel 111 or the second panel 112 .
[0037] Multiple ribs 13 are connected one by one to the middle of the first panel 111 and the middle of the second panel 112 in the horizontal direction, and one end of the rib 13 is connected to the first panel 111 or the second panel 112, and the other end extends longitudinally to be flush with the second panel 112 or the first panel 111; that is, the rib 13 is vertically connected to the first panel 111 or the second panel 112.
[0038] The permeable filter cloth 20 is wrapped around the outer periphery of the core plate 10, that is, the permeable filter cloth 20 is attached to all first panels 111, all second panels 112, and the two side panels 12, and the extended ends of all ribs 13 are also attached to the permeable filter cloth 20, thereby forming multiple drainage channels 30 between the permeable filter cloth 20 and the core plate 10; furthermore, the attachment area between the permeable filter cloth 20 and the core plate 10 is relatively large, which enables the permeable filter cloth 20 to be securely wrapped around the core plate 10. Further explanation, Figure 1 The traditional drainage board shown has a drainage channel 30a located on both sides of the core board 10a base board 11a, and the longitudinal width of the drainage channel 30a is small (basically equivalent to half of the longitudinal width of the core board 10a), and the drainage channel 30a is relatively dense, and its effective working area is small, which makes it easier for fine soil particles to clog it, and the drainage effect is poor; while the drainage board of the present invention has a larger longitudinal width of the drainage channel 30 (basically equivalent to the longitudinal width W of the core board 10), and the drainage channel 30 is relatively wide, and its effective working area is larger, so it is not easy for fine soil particles to clog it, and the drainage effect is better.
[0039] The above-mentioned schematic embodiment, through the design of the corrugated main plate 11, the arrangement of two side plates 12 and multiple rib plates 13, on the one hand increases the effective working area of the drainage channel 30, so that the drainage board has a larger drainage channel 30, solves the problem of easy clogging of traditional drainage boards, and significantly improves the drainage efficiency. On the other hand, it can ensure that the drainage board has good rigidity and compressive strength, so that it can better withstand external impact, soil extrusion and vacuum negative pressure, etc., ensure the spatial stability of the drainage channel 30, and thus ensure the reliability of the drainage function of the drainage board.
[0040] In some embodiments, the core board 10 is made from a mixture of degradable straw and degradable plastic materials; the permeable filter fabric 20 is made from a degradable non-woven fabric, making the drainage board biodegradable. After vacuum preloading is used to reinforce a soft soil foundation, the drainage board in the foundation will naturally degrade over time, losing its drainage function. This reduces post-construction settlement. Furthermore, the degradable drainage board is low-carbon and environmentally friendly, reducing environmental pollution.
[0041] refer to Figure 2-Figure 4 As shown, in some embodiments, the cross-section of the main plate 11 is a square wave shape, and the two side plates 12 extend longitudinally; further, if the outermost ends of the main plate 11 in the transverse direction are both the first panel 111, then the ends of the two side plates 12 away from the main plate 11 are longitudinally extended to be flush with the second panel 112, as shown in FIG. Figure 3The drainage board of the embodiment shown in the figure; if the outermost ends of the main body plate 11 in the transverse direction are both the second panel 112, then the ends of the two side plates 12 away from the main body plate 11 are longitudinally extended to be flush with the first panel 111; if the outermost ends of the main body plate 11 in the transverse direction are respectively the first panel 111 and the second panel 112, then the other ends of the two side plates 12 away from the main body plate 11 are longitudinally extended to be flush with the second panel 112 and the first panel 111, as shown Figure 4 The drain board of Example 2 is shown. Furthermore, the ratio of the longitudinal width W of the square-wave-shaped main plate 11 to the transverse distance D between panels in the same horizontal row is 1:2 to 1:4, which means that the ratio of the longitudinal distance to the transverse distance of the drainage channel 30 is approximately 1:1 to 1:2. This refines the dimensional design of the square-wave-shaped main plate 11 and determines the structural design of the drainage channel 30 on the drain board.
[0042] refer to Figure 5-Figure 7 As shown, in some embodiments, the cross-section of the main panel 11 is in the shape of a trapezoidal wave, that is, the lateral distance between the panels in the same horizontal row is greater than the lateral length of the first panel 111 or the second panel 112, so that the side panels 113 connected between the first panel 111 and the second panel 112 are inclined; specifically, the longitudinal angle β of the side panels 113 ranges from 0° to 30°. The two side panels 12 extend obliquely, and the two side panels 12 are respectively arranged opposite to their adjacent side panels 113; further, if the outermost ends of the main panel 11 in the horizontal direction are both the first panel 111, then the ends of the two side panels 12 away from the main panel 11 are obliquely extended to be flush with the second panel 112, as shown in FIG. Figure 6 The drainage board of the third embodiment shown; if the outermost ends of the main body plate 11 in the horizontal direction are both the second panel 112, then the ends of the two side plates 12 away from the main body plate 11 are obliquely extended to be flush with the first panel 111; if the outermost ends of the main body plate 11 in the horizontal direction are respectively the first panel 111 and the second panel 112, then the other ends of the two side plates 12 away from the main body plate 11 are obliquely extended to be flush with the second panel 112 and the first panel 111, as shown Figure 7 The drain board of the fourth embodiment shown in the figure further has a ratio of the longitudinal width W of the trapezoidal wave-shaped main plate 11 to the transverse distance D between panels in the same horizontal row of panels of 1:2 to 1:4, that is, the ratio of the longitudinal distance of the drainage channel 30 to the transverse distance of its opening is approximately 1:1 to 1:2; this refines the dimensional design of the trapezoidal wave-shaped main plate 11, and thus determines the structural design of the drainage channel 30 on the drain board.
[0043] refer to Figure 2-Figure 7As shown, in some embodiments, the permeable filter cloth 20 is directly bonded to the outside of the core plate 10 by hot melt bonding, thereby realizing a fixed connection between the core plate 10 of the drainage board and the permeable filter cloth 20; when the drainage board is subjected to soil compression, vacuum negative pressure, etc., it is ensured that the core plate 10 and the permeable filter cloth 20 are always connected together without separation or relative slippage, thereby preventing soil particles from directly entering the core plate 10 and causing siltation and blockage, thereby further ensuring the reliability of the drainage function of the drainage board.
[0044] In some embodiments, in order to simplify the production process of the drainage board, the permeable filter cloth 20 can also be first hot-melt bonded into a cylindrical shape, and then tightly sleeved on the outside of the core board 10 to complete the production of the drainage board; because the fitting area between the permeable filter cloth 20 and the core board 10 is large, it is not easy for the two to separate or slip relative to each other.
[0045] refer to Figure 2-Figure 7 As shown, in some embodiments, a plurality of first panels 111, a plurality of second panels 112, a plurality of side panels 113, two side panels 12, and a plurality of ribs 13 are integrally formed into a core panel 10, thereby achieving the integral production of the core panel 10. In some embodiments, the corners where the first panels 111 and the side panels 113 are connected, the corners where the second panels 112 and the side panels 113 are connected, and the corners where the side panels 12 and the main panel 11 are connected are all arc-shaped, so as to achieve a smooth transition between the parts, avoid cracking at the corners, and facilitate the production of the core panel 10.
[0046] To sum up, the large drainage channel degradable drainage board of the utility model has a simple structure, is easy to manufacture, and is highly practical. It can increase the effective working area of the drainage channel, so that the drainage board has a larger drainage channel, solves the problem that traditional drainage boards are prone to clogging, and significantly improves drainage efficiency. The drainage board is degradable, which reduces pollution to the environment and greatly reduces the risk of foundation settlement after construction.
[0047] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0048] The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should all be included in the scope of the technical solution for which protection is requested in the present invention.
