Description

Technical Field

[0001] The present invention relates to the field of civil engineering construction, and in particular to a single-sided formwork pile inter-plate drain pipe device and a construction method. Background Art

[0002] Pile slab construction plays an important role in the field of civil construction. It is used to connect the concrete slabs between pile foundations, and is used to bear the structural load and transfer it to the pile foundation. In large-scale construction projects, the quality of pile slab construction directly affects the overall structural safety and stability.

[0003] When the single-sided formwork construction technology is used for the pile slab of the slope support structure, the water filtration structure and the drainage pipe used in conjunction with it need to be installed in advance to meet the functional requirements. The currently commonly used water filtration structure is a filter mesh with geotextile wrapped gravel. There is no fixed connection measure between the drainage pipe and the water filtration structure. The concrete of the pile slab is poured and vibrated, resulting in a serious deviation in the relative position between the water filtration structure and the drainage pipe. The water filtration structure loses its water filtration function and even causes the drainage pipe to be blocked, completely losing its drainage function.

[0004] Therefore, it is necessary to improve the structure of the existing single-sided formwork pile-to-pile plate drain pipe device so that it can effectively solve the problems existing in the prior art. Summary of the Invention

[0005] In order to solve the above problems, the single-sided formwork pile slab drain pipe device of the present technical solution ensures the stability of the direct connection between the drain pipe and the filter box by fixedly connecting and installing the drain pipe body and the filter box body, and avoids the vibration force generated during the vibration process when pouring the pile slab concrete, which causes the relative position between the filter bag and the drain pipe to shift, thereby causing it to lose its water filtering function and even cause the drain pipe to be blocked. The filter hole is opened on the filter box body to facilitate groundwater to enter the filter box body through the opening and be discharged smoothly from the drain pipe.

[0006] A single-sided formwork pile plate drain pipe device includes a drain pipe body and a filter box body; the drain pipe body is fixedly installed on the side of the filter box body, and the side and top surfaces of the filter box body are respectively provided with side water filter holes and top water filter holes, and water filter material is arranged inside the filter box body.

[0007] Furthermore, a wedge-shaped bottom plate is installed at the bottom of the filter box body, and the thickness of the wedge-shaped bottom plate gradually decreases from left to right.

[0008] Furthermore, the water filter pipe body is fixedly installed on the right end surface of the filter box body, and the water filter pipe body is tilted relative to the horizontal direction to form an inclined angle, and the inclined angle is 4-8 degrees.

[0009] Furthermore, a water filter material filling port is provided on the upper end surface of the filter box body, and an opening cover is provided at the opening of the water filter material filling port.

[0010] Furthermore, the direction of the side water filter holes forms a water filter hole angle relative to the vertical direction, and the water filter hole angle is 45-55 degrees.

[0011] Furthermore, the filter box body is in the shape of a rectangular parallelepiped as a whole, and a positioning ring is fixedly connected and installed on the right end surface of the filter box body.

[0012] A construction method for a single-sided formwork pile-slab drain pipe device comprises the following steps:

[0013] S1: Fill the filter box with water filter material, and after filling, lock the opening cover on the filter box;

[0014] S2: The filter box is installed at the construction site, and the drain pipe body passes through the reinforcement cage of the pile plate and extends to an appropriate length;

[0015] S3: After passing the steel wire through the positioning ring, tighten the installation with the reinforcement cage between the piles to ensure the stable installation of the filter box.

[0016] The beneficial effects of the present invention are as follows: the single-sided formwork pile slab drain pipe device of the present technical solution ensures the stability of the direct connection between the drain pipe and the filter box by fixedly connecting and installing the drain pipe body and the filter box body, and avoids the vibration force generated during the vibration process when pouring the pile slab concrete, which causes the relative position between the filter bag and the drain pipe to be offset, thereby causing the filter bag to lose its water filtering function and even cause the drain pipe to be blocked. The filter hole is opened on the filter box body to facilitate groundwater to enter the filter box body through the opening and be discharged smoothly from the drain pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0018] Figure 1 It is a side schematic diagram of the present invention;

[0019] Figure 2 It is a top view schematic diagram of the present invention;

[0020] Figure 3 It is a schematic diagram of the side water filter hole of the present invention. DETAILED DESCRIPTION

[0021] Figure 1 It is a schematic side view of the present invention as a whole; Figure 2 It is a top view schematic diagram of the present invention; Figure 3This is a schematic diagram of the side water filter holes of the present invention. As shown in the figure, a single-sided formwork pile plate drain pipe device includes a drain pipe body 1 and a filter box body 2; the drain pipe body 1 is fixedly installed on the side of the filter box body 2, and the side and top surfaces of the filter box body 2 are respectively provided with side water filter holes 21 and top water filter holes, and the filter box body is provided with water filter material (existing filter material can be used); the single-sided formwork pile plate drain pipe device of this technical solution ensures the stability of the direct connection between the drain pipe and the filter box by fixedly connecting and installing the drain pipe body and the filter box body, and avoids the relative position between the filter bag and the drain pipe being offset due to the vibration force generated during the vibration process when pouring the pile plate concrete, thereby causing the filter bag to lose its water filtering function and even causing the drain pipe to be blocked. The water filter holes are provided on the filter box body to facilitate groundwater to enter the filter box body through the openings and be discharged smoothly from the drain pipe.

[0022] In this embodiment, a wedge-shaped bottom plate 24 is installed at the bottom of the filter box body 2, and the thickness of the wedge-shaped bottom plate 24 gradually decreases from left to right. Figure 1 As shown, a wedge-shaped bottom plate is fixedly connected to the bottom of the filter box body 2, and the thickness of the bottom plate gradually decreases from left to right, so as to form a diversion structure, and the internal accumulated water is filtered and then flows to the drain pipe body 1.

[0023] In this embodiment, the water filter pipe body 1 is fixedly installed on the right end surface of the filter box body (i.e. Figure 1 The filter body 1 is tilted relative to the horizontal to form an angle of 4-8 degrees. The filter body 1 is fixedly mounted on the right end surface of the filter cartridge 2, forming an integral structure. This prevents the two structures from separating during subsequent construction, which could lead to filtration failure. The filter body 1 is tilted downward relative to the horizontal to facilitate drainage of accumulated water.

[0024] In this embodiment, the upper end surface of the filter cartridge body 2 is provided with a filter material filling port 25, and an opening cover is provided at the filter material filling port opening 25. The filter cartridge body 2 is provided with a filter material filling port opening 25 at the upper end to facilitate filling the filter material into the cartridge body. The opening is closed by the opening cover. The middle portion of the upper end surface of the filter cartridge body 2 is slightly raised upward, i.e., the middle portion is the highest, and the portions gradually decrease from the middle portion to the outer edge, so that water from the upper portion can flow more easily into the interior of the filter cartridge body 2.

[0025] In this embodiment, the side filter holes 22 form a filter hole angle relative to the vertical direction, and the filter hole angle is 45-55 degrees. Figure 3 As shown, the side water filter holes 22 opened on the four sides of the filter box body 2 preferably have an opening angle of 50° relative to the vertical direction, so as to better guide the accumulated water around the water filter box body into the box body for discharge.

[0026] In this embodiment, the filter box body is generally rectangular in shape, with a positioning ring 23 fixedly mounted on the right end surface of the filter box body. The filter box body 2 is generally rectangular in shape and can be made of metal materials such as stainless steel or other materials. Compared with traditional water filtration structures, this structure has better load-bearing performance and is more stable when installed with the water filter pipe body 1. The positioning ring 23 is fixedly mounted on the filter box body 2 and is tightened and installed using steel wire or U-shaped structural steel bars in conjunction with the pile inter-plate reinforcement cage frame structure to ensure the stability of the overall installation structure.

[0027] The construction method of the single-sided formwork pile inter-slab drain pipe device includes the following steps:

[0028] S1: Fill the filter box with filter material and lock the opening cover on the filter box after filling. Open the opening cover of the filter box 2 and fill the filter material. After filling, check whether the opening on the filter box is blocked and check whether the drain pipe body 1 is blocked.

[0029] S2: Install the filter box body to the construction location, and the drain pipe body passes through the steel cage between the piles and extends to the appropriate length; install the filter box body 2 to the construction location, ensuring that the drain pipe body 1 passes through the steel cage without interference, and the extended length of the drain pipe end meets the construction requirements;

[0030] S3: After threading the steel wire through the positioning rings, secure the filter box with the inter-pile slab reinforcement cage to ensure stable installation. After threading steel wire or U-shaped reinforcement through each positioning ring 23, secure the cage with steel wire to ensure the stability of the overall structure. This provides reliable support for the subsequent pouring of the inter-pile slab concrete and prevents the overall structure from vibrating out of its intended position.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
