Description

Technical Field

[0001] The present application relates to the field of landslide control technologies, and particularly relates to a multi-anti-slide pile linkage structure. Background Art

[0002] An anti-slide pile is a protective structure that inserts a pile into the sliding bed below the sliding surface to stabilize a landslide. The sliding bed is composed of underground stable rock and soil layers. The anti-slide pile utilizes the anchoring effect of the rock and soil in the sliding bed to balance the thrust of the sliding mass, thereby achieving the purpose of stabilizing the landslide.

[0003] In the prior art, anti-slide piles are mainly made of reinforced concrete. During the construction of anti-slide piles, multiple circular anti-slide piles are set in the sliding mass, so that the sliding mass is connected to the stable bottom layer through the anti-slide piles to achieve the reinforcement effect on the sliding mass; or an anti-slide retaining wall is set to intercept the sliding mass.

[0004] In practical applications, for the terrain that is gentle first and then steep from bottom to top near the river, the sliding mass usually exists in the middle of the river beach to the mountain body in the part near the river. If a landslide occurs, it will not only affect the geology but also have a great negative impact on the water quality of the river. Therefore, it is often necessary to reinforce both the lower part and the middle part of the part near the river.

[0005] Since the flexural section modulus of a circular anti-slide pile is relatively low and the hole-forming efficiency of the pile hole is high, while the construction difficulty of a non-circular anti-slide pile is relatively large. At this time, a relatively large number of anti-slide piles need to be set for reinforcement treatment, which will result in a relatively large number of anti-slide piles and requires multiple transfers of the construction site for the construction of anti-slide piles. If non-circular anti-slide piles are used, relatively complicated construction processes need to be carried out at different positions respectively, and the hole-forming efficiency is low, which is time-consuming and laborious. Therefore, how to carry out relatively efficient construction for the part near the river while reducing the impact on the retaining effect is an urgent problem to be solved at present. Summary of the Invention

[0006] In order to optimize the construction efficiency while reducing the impact on the retaining effect of the sliding mass, the present application provides a multi-anti-slide pile linkage structure.

[0007] The multi-anti-slide pile linkage structure provided by the present application adopts the following technical solutions:

[0008] A multi-anti-slide pile linkage structure includes a plurality of round piles and a plurality of square piles. The plurality of round piles are arranged in the middle of the sliding mass. The plurality of round piles are divided into multiple groups along the inclined direction of the sliding mass, and the multiple round piles in the same group are distributed horizontally. Adjacent two groups of the round piles are arranged in a staggered manner. The plurality of square piles are arranged in the part near the river of the sliding mass. The square piles are arranged below the round piles and are located at the bottom of the sliding mass.

[0009] By adopting the above technical solutions, since the soft soil in the sliding mass is affected by rainwater, etc., the soil at the bottom of the sliding mass will be relatively softer than that in the middle. However, the bottom of the sliding mass is relatively prone to a sliding trend during rain. Therefore, the circular piles are arranged in the middle of the sliding mass, which can achieve the effects of preliminary reinforcement and convenient construction of the sliding mass, and can also block the sliding mass when it flows. However, compared with square piles, the impact and force on the circular piles are relatively small. Therefore, by arranging them in a staggered manner, when the sliding mass flows, part of it will directly flow downward through the gaps between the circular piles, and part will flow horizontally, thereby further slowing down the sliding trend of the sliding mass. The square piles arranged at the bottom of the sliding mass are concentrated in the relatively soft geological part of the sliding mass. Therefore, when the pile holes of the square piles are constructed manually or by impact, it can be carried out relatively efficiently, and the formed square piles can further optimize the supporting effect on the sliding mass.

[0010] Optionally, the square pile includes a pile body and a plurality of retaining walls sleeved on the pile body. The plurality of retaining walls are stacked along the length direction of the pile body. The retaining walls are annular and the outer wall contour is square. The inner walls of the retaining walls are provided with arc transitions at the positions corresponding to the corners of the pile body. The retaining walls are used to support the inner wall of the pile hole when drilling the pile hole, and the pile body is adapted to the inner wall of the retaining wall.

[0011] By adopting the above technical solutions, since the square piles are concentrated at the bottom of the sliding mass where the geology is relatively soft, the pile holes are extremely prone to the phenomenon of hole collapse during construction. Therefore, at this time, the retaining walls can successively support the pile holes from top to bottom. The inner walls of the retaining walls are circular arcs at the corner positions, which can reduce the pile forming defect of air pockets caused by the corners when pouring concrete. At the same time, the retaining walls can also isolate the pile body from the external soil mass, so that the retaining walls can support the pile holes, optimize the pile forming quality of the pile body, and play the role of retaining the sliding mass.

[0012] Optionally, a waterproof ring is provided at the splicing part of adjacent retaining walls. The two ends of the waterproof ring along the length direction of the central axis of the pile body are preset inside the retaining walls in sequence according to the pouring order of the retaining walls.

[0013] By adopting the above technical solutions, it can further isolate the groundwater inside and outside the retaining walls and reduce the influence of the groundwater outside the retaining walls on the pile forming of the pile body.

[0014] Optionally, a connecting piece inserted and matched with the pile body is preset inside the retaining wall.

[0015] By adopting the above technical solutions, the retaining wall and the pile body can be relatively tightly combined to optimize the stability of retaining the sliding mass and reduce the possibility of damage to the retaining wall caused by impact.

[0016] Optionally, the connecting member includes a connecting sleeve and a plugging rod. The connecting sleeve is preset inside the retaining wall as a whole, and the end of the connecting sleeve is flush with the inner wall of the retaining wall. The plugging rod is preset inside the pile body, and the connecting sleeve is sleeved outside and threadedly connected to the plugging rod.

[0017] By adopting the above technical solution, when pouring the retaining wall, the connecting sleeve is preset inside the retaining wall, so that when pouring the pile body, the plugging rod can be threadedly connected to the plugging rod, realizing the purpose that the pile body and the retaining wall can still be connected to each other after being poured successively.

[0018] Optionally, a positioning sleeve covering the end of the connecting sleeve is sleeved at one end of the connecting sleeve facing the plugging rod, and the positioning sleeve is made of an elastic material.

[0019] By adopting the above technical solution, since the plugging rod needs to be threadedly connected to the connecting sleeve, during pouring, it is very easy for concrete to appear inside the connecting sleeve due to the gap between the connecting sleeve and the formwork. At the same time, due to the existence of the thread, it is extremely difficult to clean the connecting sleeve. At this time, the positioning sleeve can play a sealing role during the pouring of the retaining wall to reduce the negative impact on the pile forming quality due to excessive water seepage.

[0020] Optionally, a part of the connecting sleeve is bent downward and inserted into the adjacent retaining wall in a mating manner.

[0021] By adopting the above technical solution, since the retaining wall is formed by pouring layer by layer from top to bottom during construction, if a hole structure for pouring concrete is reserved on the formwork, at the top position of the formwork, the concrete cannot be fully filled, thus it is very easy to form a cavity and cause pile body defects. At this time, the concrete can be directly filled by pouring through the connecting sleeve from top to bottom, so that the concrete can be relatively fully filled to effectively reduce the possibility of defects such as cavities.

[0022] Optionally, the retaining wall is provided with a relief hole. One end of the relief hole communicates with the inner side of the retaining wall, the other end of the relief hole is arranged to open downward, and a part of the structure at the top of the retaining wall extends into the upper relief hole.

[0023] By adopting the above technical solution, air can be discharged in time during the process of concrete filling. At the same time, the concrete can be relatively fully filled and the concrete can be discharged upward from the relief hole, so that the filling situation of the concrete at different positions can be judged by the overflow situation of the concrete in the relief hole during construction, effectively optimizing the pouring quality of the retaining wall, and thus optimizing the stability of the landslide retaining.

[0024] Optionally, steel reinforcement cages are arranged inside both the retaining wall and the pile body, and the connecting sleeve is fixedly connected to the steel reinforcement cage inside the retaining wall, and the plugging rod is fixedly connected to the steel reinforcement cage inside the pile body.

[0025] By adopting the above technical solution, the steel reinforcement cages in the retaining wall and the pile body are connected through the connecting sleeves and the inserting rods, so as to further optimize the integrity of the retaining wall and the pile body, and optimize the stability of the landslide retaining.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Due to the influence of rainwater and the like on the soft soil in the landslide, the soil at the bottom of the landslide is relatively softer than that in the middle. However, the bottom of the landslide is relatively prone to sliding tendency when it rains. Therefore, the circular pile is arranged in the middle of the landslide, which can play the effects of preliminary reinforcement and convenient construction on the landslide, and can play a blocking effect when the landslide flows. However, compared with the square pile, the impact and force received by the circular pile are relatively small. Therefore, the dislocation setting can make part of the landslide flow directly downward through the gaps of the circular pile and part of it flow horizontally when the landslide flows, so as to further slow down the flowing tendency of the landslide; and the square pile arranged at the bottom of the landslide, because the soft soil is concentrated, can be carried out relatively efficiently when the pile hole of the square pile is constructed manually or by impact, and the formed square pile further optimizes the supporting effect on the landslide.

Detailed implementation manners

[0038] The following further elaborates on this application Figures 1-9 in conjunction with the accompanying drawings.

[0039] The embodiment of this application discloses a multi - anti - sliding pile linkage structure. Referring to Figure 1 , the multi - anti - sliding pile linkage structure includes multiple round piles 1 and multiple square piles 2. The outer contour of the round pile 1 is circular, and the outer sidewall contour of the square pile 2 is square. The multiple round piles 1 are divided into multiple groups and the multiple groups are staggered successively from top to bottom along the sliding body 3. Adjacent two groups of round piles 1 are staggered horizontally, and the multiple round piles 1 in the same group are distributed horizontally. At the same time, the multiple square piles 2 are also divided into multiple groups distributed from top to bottom along the sliding body 3, and adjacent two groups of square piles 2 are arranged with horizontal dislocation, and the square piles 2 are located below the round piles 1. Among them, both the round piles 1 and the square piles 2 are reinforced concrete structures.

[0040] Both the round piles 1 and the square piles 2 penetrate through the sliding body 3 and are implanted into the sliding bed 31. The multiple round piles 1 are arranged in the middle of the sliding body 3 and are array - distributed. Among them, the sliding body 3 is a landslide body, and the sliding bed 31 is the underlying immovable body that the sliding body 3 relies on when sliding.

[0041] Assume that the cross - sectional areas of the round pile 1 and the square pile 2 are the same, both being A. The width of the rectangular cross - section is b, the length is h; the radius of the circular cross - section is d. Then: The area of the rectangular anti - sliding pile cross - section: A = bh, and the flexural section modulus is: W1=(bh 2 ) / 6.

[0042] The area of the circular anti - sliding pile cross - section is: A = πd 2 ² / 4; the flexural section modulus is: W2=(πd 3 ³) / 32.

[0043] Then, W1 / W2=1.33h / d; due to the same cross-sectional area, h>d, it can be concluded that under the same cross-sectional condition, W1>W2, so the bending section coefficient of square pile 2 is relatively better. At this time, round pile 1 can be set in the middle of sliding body 3 to reduce the construction difficulty. Moreover, since the soil with relatively strong fluidity in sliding body 3 is concentrated at the bottom of sliding body 3, round pile 1 can reinforce the middle and top parts of sliding body 3, and make the soil with relatively strong fluidity flow relatively slowly toward the position where square pile 2 is located, so as to reduce the impact and pressure on round pile 1 in the upper part of sliding body 3. At the same time, by setting square pile 2 at the bottom of sliding body 3, the part with relatively strong fluidity gathered at the bottom of sliding body 3 is strengthened to support and stabilize, and the influence of water flow in the river on the riverside part of sliding body 3 is reduced simultaneously, so as to reduce the construction difficulty and the influence on the retaining effect at the same time.

[0044] Reference Figure 2 and Figure 3 Specifically, the square pile 2 includes a pile body 22 and a plurality of protective walls 21, the protective walls 21 are annular, and the plurality of protective walls 21 are distributed along the length direction of the square pile 2, the protective walls 21 are fitted over the pile body 22, and the plurality of protective walls 21 are stacked along the length direction of the pile body 22. The protective walls 21 and the pile body 22 are both reinforced concrete, that is, the protective walls 21 and the pile body 22 are both provided with a steel cage 5 inside to optimize the strength of the protective walls 21 and the pile body 22.

[0045] Reference Figure 3 and Figure 4 The outer circle of the cross section of the retaining wall 21 is square, and the inner circle of the cross section of the retaining wall 21 is arc-shaped at the positions corresponding to the four corners. The outer wall of the pile body 22 is adapted to the inner wall of the retaining wall 21, and the retaining wall 21 is used to support the inner wall of the pile hole when drilling the pile hole, so as to reduce the possibility of hole collapse due to the relatively strong or soft fluidity of the soil inside the sliding body 3 during the drilling process. The successive splicing of multiple retaining walls 21 can also play the effect of separating external mud and water, and optimize the pile quality of the pile body 22; at the same time, the inner wall of the retaining wall 21 is arc-shaped at the positions corresponding to the corners of the outer circle, so that during the pouring process of the pile body 22, the concrete can be relatively fully filled in the inner space of the retaining wall 21, so as to reduce the possibility of defects such as cavities at the corresponding corners of the retaining wall 21 due to the slag in the corresponding area of ​​the pile hole, so as to maintain the square outline of the retaining wall 21 while reducing the construction difficulty during the pouring process of the retaining wall 21, and can also optimize the blocking effect of the sliding of the sliding body 3 through the outer square outline of the retaining wall 21.

[0046] Reference Figure 5, In addition, since the construction of the retaining wall 21 is carried out by pouring and forming layer by layer from top to bottom, the joints between adjacent retaining walls 21 are joints between new and old concrete. In order to further optimize the waterproof performance at the joints between new and old concrete of adjacent retaining walls 21, a waterproof ring 211 is provided at the splicing part of adjacent retaining walls 21. The waterproof ring 211 is sleeved outside the pile body 22, and both ends of the waterproof ring 211 along the central axis direction of the pile body 22 are preset inside the retaining wall 21 successively according to the pouring sequence of the retaining wall 21 from top to bottom, so as to waterproof the joints between adjacent retaining walls 21. Among them, the waterproof ring 211 is made of metal, rubber or plastic.

[0047] Refer to Figure 5 and Figure 6 , Specifically, in order to further optimize the integrity between the retaining wall 21 and the pile body 22, a connecting piece 4 is provided between the retaining wall 21 and the pile body 22 to connect the retaining wall 21 relatively tightly to the pile body 22. The connecting piece 4 includes a connecting sleeve 41 and a plugging rod 42. The connecting sleeve 41 is preset inside the retaining wall 21 as a whole, and one end of the connecting sleeve 41 is sleeved outside and threadedly connected to the plugging rod 42, and the other end of the connecting sleeve 41 is sleeved outside and threadedly connected to the steel bar of the steel reinforcement cage 5 inside the retaining wall 21 or is bent downward and plugged into the inside of the adjacent retaining wall 21; specifically, the connecting sleeve 41 located in the middle and top of the retaining wall 21 is fixedly connected to one end of the steel reinforcement cage 5 and is closed, while the connecting sleeve 41 located at the bottom of the retaining wall 21 is bent downward. At the same time, the plugging rod 42 is preset inside the pile body 22 as a whole, and the plugging rod 42 is fixedly connected to the steel reinforcement cage 5 inside the pile body 22.

[0048] The downward-bent connecting sleeve 41 is arranged at the bottom of the retaining wall 21, so that when pouring multiple retaining walls 21 layer by layer from top to bottom, concrete can be poured into the adjacent lower retaining wall 21 through the connecting sleeve 41 during pouring. Compared with using formwork to reserve pouring holes, using the connecting sleeve 41 can pour from top to bottom without the need for additional design and processing of the formwork, which can optimize the construction convenience and the processing difficulty of the formwork.

[0049] Refer to Figure 5 and Figure 6 , At the same time, in order to reduce the possibility of concrete entering the connecting sleeve 41 inside the corresponding retaining wall 21 during the pouring of the retaining wall 21, a positioning sleeve 43 is sleeved outside the end of the connecting sleeve 41 facing the inner side of the retaining wall 21. The positioning sleeve 43 covers the end of the connecting sleeve 41 and is used to abut and cooperate with the formwork during the pouring of the retaining wall 21, so as to separate the concrete between the end of the connecting sleeve 41 and the formwork.

[0050] Refer to Figure 7, In addition, in order to further ensure that the concrete is fully filled during the pouring of the retaining wall 21, an avoidance hole 212 is reserved in the retaining wall 21 during pouring. One end of the avoidance hole 212 communicates with the inner side of the retaining wall 21, and the other end of the avoidance hole 212 bends downward and extends with a downward opening, so that during the pouring process, after the concrete fills between the formwork of the retaining wall 21 and the inner wall of the pile hole, the concrete can be discharged from the avoidance hole 212 successively and fill the avoidance hole 212. While balancing the pressure during the concrete filling process, it can also judge the filling condition of the concrete at different positions by the degree and pressure of the concrete overflowing from the avoidance holes 212 at different positions, so that the concrete can be relatively fully filled. At the same time, it can also judge whether the concrete is relatively fully filled during the pouring of the retaining wall 21 by whether there is concrete overflow from the avoidance holes 212, reducing the possibility of quality defects during the forming process of the retaining wall 21.

[0051] In order to form the avoidance hole 212, an avoidance sleeve 213 is preset in the retaining wall 21. The two ends of the avoidance sleeve 213 communicate with the inner side of the retaining wall 21 and are provided with a downward opening respectively, and the end of the lower opening of the avoidance sleeve 213 is flush with the lower end surface of the retaining wall 21, so that the avoidance hole 212 can be formed inside the avoidance sleeve 213 during the pouring of the retaining wall 21.

[0052] Refer to Figure 7 and Figure 8 , Specifically, a sealing member 23 is provided at the end of the avoidance sleeve 213 facing the inner side of the retaining wall 21, so as to timely block the avoidance hole 212 and make the concrete flow towards the unfilled part when pouring the concrete into the avoidance hole 212 for the pouring of the retaining wall 21 below the avoidance sleeve 213.

[0053] The plugging member 23 includes a plugging rod 231 and a plugging pipe 232. The plugging rod 231 is fixedly connected to the inner wall of the avoidance sleeve 213 through a plurality of connecting rods 233, and the plugging rod 231 and the plugging pipe 232 are arranged on the same central axis. The outer wall of the plugging rod 231 is in a frustum shape with the small end facing the plugging pipe 232. The plugging pipe 232 is slidably connected to the inner wall of the avoidance sleeve 213, and one end of the plugging pipe 232 facing the inner side of the retaining wall 21 is bent inward and formed with a butting pipe 234. The inner wall of the butting pipe 234 is in a frustum shape with the large end opening facing the inner side of the retaining wall 21 for butting and cooperating with the outer wall of the plugging rod 231 to plug the avoidance hole 212. At the same time, a plugging spring 235 sleeving the plugging rod 231 is arranged at one end of the butting pipe 234 facing the inner side of the retaining wall 21 to drive the butting pipe 234 away from the plugging rod 231, so as to reduce the possibility that the plugging pipe 232 moves towards the plugging rod 231 due to the air discharged from the avoidance hole 212 during concrete pouring and plugs the avoidance hole 212; in addition, after the avoidance hole 212 is filled with concrete by pouring, it will push the butting pipe 234 to move towards the plugging rod 231 and compress the plugging spring 235, so that the butting pipe 234 butts and cooperates with the plugging rod 231 to plug the avoidance hole 212.

[0054] The implementation principle of the embodiment of the present application is as follows: during use, the overall structure of the stable slide 3 is stabilized by the round pile 1, and at the same time, the resistance to the flow of the slide 3 is optimized by the square pile 2 to achieve the optimization of the dual effects of efficiency and soil fixation. At the same time, during the construction process of the square pile 2, on the one hand, because the drilling area is located in the slide 3, there are relatively many soft soil masses, and the possibility of hole collapse is extremely high. At this time, the retaining wall 21 can not only play the role of supporting the pile hole during construction, but also separate the soil body and the concrete during the pouring of the pile body 22, and optimize the quality of the formation of the pile body 22 and the pouring of the retaining wall 21.

[0055] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
