Description

Technical Field

[0001] The invention discloses a high-efficiency soft foundation treatment device based on a composite process of a drainage board and a dynamic compaction replacement, which is used for high-efficiency soft foundation treatment of the composite process of a drainage board and a dynamic compaction replacement, and belongs to the technical field of soft foundation treatment devices. Background Art

[0002] The combination of drainage board and dynamic compaction replacement technology with aggregate graded ballasting is a comprehensive soft foundation treatment method designed to improve the bearing capacity and stability of soft soil foundations. The specific steps are:

[0003] A detailed geological survey is conducted in the early stages to understand the nature, distribution, and permeability of the foundation soil. Based on these findings, a drainage board layout plan, dynamic compaction replacement parameters, and aggregate graded ballasting scheme are designed. Sufficient drainage boards and aggregate (such as sand and gravel) are prepared, ensuring that the aggregate meets grade requirements. Next, drainage board installation is carried out. According to the design drawings, holes are positioned and drilled to the desired depth. The drainage boards are inserted into the holes (or, if the soft foundation is suitable for drainboard insertion, the boards can be inserted directly without drilling). Ensure that the bottom of the drainboard reaches the bottom of the soft soil layer and the top is fixed above the ground. The drainboard is then connected to a drainage system, such as a horizontal drain pipe or vertical drain well. Dynamic compaction replacement construction is then carried out. Ramming points are arranged according to the design, typically in a plum blossom or square pattern. A dynamic compactor is used to perform preliminary tamping on the foundation to displace some of the soft soil, forming the rammed-replacement pier. Tamping energy is controlled based on the soil conditions and design requirements to avoid excessive or insufficient tamping. Finally, graded aggregate is laid on top of the rammed-replacement pier, with the aggregate particle size and gradation specified in the design. Use a roller or other compacting equipment to compact the laid aggregate to ensure that the aggregate layer is dense.

[0004] However, the combination of drainage board and dynamic compaction replacement composite process in the prior art has the following technical problems:

[0005] The inability to quickly and accurately lay out the drainage boards, that is, the spacing between the drainage boards is too large or the arrangement is not neat, will cause the drainage paths in some areas to be longer than in other areas, thereby affecting the dissipation rate of the pore water pressure, and failing to ensure uniform drainage and uniform reinforcement of the soft foundation, affecting the overall drainage and reinforcement effects. Utility Model Content

[0006] The purpose of this utility model is to provide an efficient soft foundation treatment device based on a composite process of drainage boards and dynamic compaction replacement, to solve the problem that the drainage boards cannot be laid out quickly and accurately, that is, the spacing between the drainage boards is too large or the arrangement is not neat, which will cause the drainage paths in some areas to be longer than other areas, thereby affecting the dissipation speed of the pore water pressure, and unable to ensure uniform drainage and uniform reinforcement of the soft foundation, affecting the overall drainage and reinforcement effects.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A high-efficiency soft foundation treatment device based on a composite process of a drainage board and dynamic compaction replacement comprises a main positioning piece and a plurality of auxiliary positioning pieces arranged on the main positioning piece for positioning the drainage board.

[0018] Furthermore, each side of the hollow positioning frame is provided with a limiting hole for installing a positioning rod to position adjacent structures.

[0019] Furthermore, the bottom of the hollow positioning frame is provided with fixing teeth.

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] First, the utility model positions the auxiliary positioning member by positioning the main positioning member on the soft foundation, and positions the setting position of the drainage board through the auxiliary positioning member, so that the drainage board can be quickly and accurately arranged through the auxiliary positioning member, which can effectively avoid the arrangement of the drainage board with too large spacing or irregular arrangement, which will cause the drainage path in some areas to be longer than that in other areas, thereby affecting the dissipation speed of the pore water pressure, ensuring uniform drainage and uniform reinforcement of the soft foundation, and improving the overall drainage and reinforcement effect;

[0026] 6. The fixing member in the present invention is a slide plate that slides in conjunction with the chute, and a screw rod connected to the through hole and the slide plate. The position of the slide plate in the square frame is adjusted by the cooperation of the nut and the screw rod, which not only further defines the insertion position of the drain board, but also enables the slide plate to cooperate with the square frame to clamp the drain board.

[0027] 7. The purpose of setting scale B in the present invention is to facilitate the rapid adjustment of the slide to the specified position in the square frame;

[0028] 8. The hollow positioning frame in the present invention is defined as a square structure in order to facilitate the installation of auxiliary positioning members to facilitate the positioning of the insertion position of the drainage board;

[0044] Example 1

[0045] In order to solve the problem that the existing technology cannot quickly and accurately lay out the drainage boards, that is, the spacing between the drainage boards is too large or the arrangement is not neat, which will cause the drainage path in some areas to be longer than other areas, thereby affecting the dissipation speed of the pore water pressure, and failing to ensure uniform drainage and uniform reinforcement of the soft foundation, affecting the overall drainage and reinforcement effect. Figure 1-4 As shown, a high-efficiency soft foundation treatment device based on a composite process of a drainage board and dynamic compaction replacement is provided, comprising a main positioning member 1 and a plurality of auxiliary positioning members 2 arranged on the main positioning member 1 for positioning the drainage board.

[0046] In practice, based on the center of the compaction replacement pier body, a positioning instrument (such as an infrared positioning instrument) is used to locate the position of the main positioning part on the soft foundation to locate the auxiliary positioning part, and the setting position of the drainage board is located by the auxiliary positioning part, so that the drainage board can be quickly and accurately arranged through the auxiliary positioning part, so that the multiple auxiliary positioning parts located on the main positioning body can enable construction personnel to quickly insert the drainage board around the position of the compaction replacement pier body, which can effectively avoid the arrangement of the drainage board with too large spacing or uneven arrangement, which will cause the drainage path in some areas to be longer than other areas, thereby affecting the dissipation rate of the pore water pressure, ensuring uniform drainage and uniform reinforcement of the soft foundation, and improving the overall drainage and reinforcement effect.

[0047] Example 2

[0048] Based on Example 1, the main positioning member 1 includes a hollow positioning frame 3, a horizontal transverse positioning rod 4 and / or a horizontal longitudinal positioning rod 5 arranged on the hollow positioning frame 3 and parallel to the arrangement direction of the drainage board, and a positioning hole 6 arranged on the horizontal transverse positioning rod 4 and / or the horizontal longitudinal positioning rod 5 and passing through the longitudinal axis of the container.

[0049] In practice, based on the center of the compaction replacement pier body, a positioning instrument (such as an infrared positioning instrument) is used to set the horizontal transverse positioning rod or / and the horizontal longitudinal positioning rod in parallel with the arrangement direction of the drainage board. At the same time, the positioning instrument is used to overlap the center of the positioning hole with the central axis of the compaction replacement pier body to realize the positioning of the main positioning member 1. After positioning, when multiple auxiliary positioning members are fixed on the main positioning member, the auxiliary positioning members are positioned. When it is a movable setting, it is necessary to adjust the position of the auxiliary positioning members on the main positioning member in advance and fix them. When the main positioning member is positioned, the auxiliary positioning members are also positioned. This structure is not only simple in structure, but also convenient in positioning. After positioning, the drainage boards can be positioned one by one, which can effectively improve the efficiency of accurate and uniform layout of the drainage boards.

[0050] Example 3

[0051] Based on Example 2, the auxiliary positioning member 2 includes a plurality of connecting members 7 provided on opposite sides of the hollow positioning frame 3, a square frame 8 provided on the connecting member 7 for allowing the drain board to pass through, and a fixing member 9 movably provided on the square frame 8 for limiting the position of the drain board or fixing the drain board when docking with the drain pipe. The auxiliary positioning member is positioned when the main positioning member is positioned. At this time, the drain board can be further limited in position in cooperation with the square frame and the fixing member so that it can be inserted into the soft foundation. When the drain board is fixed to the drain pipe, it can also be fixed by the fixing member to prevent the drain board from being pulled when fixed to the drain pipe, thereby affecting its insertion depth.

[0052] A T-shaped slot 10 is provided on one opposing side of the hollow positioning frame 3; the connecting member 7 includes a T-shaped screw 11 slidably disposed within the T-shaped slot 10, a nut 12 disposed on the T-shaped screw 11, and the square frame 8 is disposed on the T-shaped screw 11. The provision of a T-shaped slot on one opposing side of the hollow positioning frame and the definition of the connecting members as T-shaped screws and nuts facilitates adjusting the T-shaped screws to drive the square frame and the fixing member to move on the main positioning member according to practical needs, thereby positioning the drainage board with different spacing requirements.

[0053] On one side of the T-shaped chute 10 , a scale A13 is provided on the hollow positioning frame 3 . The purpose of providing the scale A is to facilitate rapid adjustment of the auxiliary positioning members to a specified position according to the spacing requirements between the auxiliary positioning members.

[0054] Along the length of the T-shaped chute 10, a chute 14 is provided on the inner side of the opposite side of the square frame 8. The opposite end connected to the T-shaped screw 11 is provided with a through hole 15 in the square frame 8 that communicates with the chute 14. The fixing member 9 includes a slide 16 that slidably engages with the chute 14, a screw 17 disposed on the slide 16 and slidably engages with the through hole 15, and a nut disposed on the screw 17. The fixing member comprises the slide that slidably engages with the chute, and the screw connected to the through hole and the slide. The nut and screw cooperate to adjust the position of the slide within the square frame, not only further defining the insertion position of the drain board, but also allowing the slide to cooperate with the square frame to clamp the drain board. If the drain board is located on the square frame 8 on one side of the T-shaped chute 10 or on the opposite side of the T-shaped chute 10, the screw 17 can be pulled to drive the slide plate 16 to slide in the chute 14 toward the side of the T-shaped chute 10 or the opposite side, and the nut is used to limit the position. At this time, the drain board can be inserted into the space formed by the slide plate and the square frame and inserted into the soft foundation. When the drain board needs to be fixed to the drain pipe, the drain board can be clamped by the slide plate, the square frame and the nut, and then the top end of the drain board is fixed to the drain pipe to avoid pulling the drain board during fixing, which affects its insertion depth.

[0055] Example 4

[0056] Based on Example 3, a scale B18 is provided on the square frame 8 along the length of the chute 14. The purpose of providing the scale B is to facilitate the rapid adjustment of the slide to a specified position in the square frame to form a positioning space for limiting the drainage board.

[0057] Example 5

[0058] On the basis of embodiment 4, the hollow positioning frame 3 is a square structure, in order to facilitate the arrangement of auxiliary positioning members, so as to facilitate the positioning of the insertion position of the drainage board.

[0059] Example 6

[0060] Based on Example 5, each side of the hollow positioning frame 3 is provided with a limiting hole 19 for mounting a positioning rod to position adjacent structures. The limiting holes are provided to facilitate positioning of adjacent primary positioning members through the cooperation of the positioning rods and the limiting holes, thereby avoiding secondary positioning by positioning instruments and further improving the efficiency of drain board installation. Specifically, positioning rods of different lengths are matched with the limiting holes 19 of adjacent structures, so that the positioned primary positioning members can position the unpositioned primary positioning members.

[0061] Example 7

[0062] On the basis of Example 6, the bottom of the hollow positioning frame 3 is provided with fixing teeth 20, the purpose of which is to fix the main positioning part and at the same time to enhance the strength during positioning of the soft base, so as to effectively avoid the problem of the main positioning part sinking in the soft base. In practice, the main positioning part and the auxiliary positioning part are made of lightweight materials, such as plastic plates.
