[0027] The following is combined with Figure 1-3 This application is described in further detail.
[0028] The embodiment of the present application discloses an anti-sliding pile-sheet wall on an unstable slope.
[0029] Reference Figure 1-3 The unstable slope anti-sliding pile-board wall comprises an anti-sliding pile 1, a retaining board 2 and an embedded bottom structure 3.
[0030] The anti-slide pile 1 is a reinforced concrete structure and the pile hole is dug deep into the soil layer. The anti-slide pile 1 is an upright rectangular parallelepiped structure. There are multiple anti-slide piles 1 and they are distributed along the foot of the slope.
[0031] There are multiple retaining plates 2, each of which is located between any two adjacent anti-slip piles 1; the retaining plates 2 are provided with drainage holes 21 along the thickness direction, the drainage holes 21 are inclined and one end close to the slope is positioned upward; the drainage holes 21 are used to draw out water in the soil to avoid excessive reduction in the shear strength of the soil and reduce the weight of the soil.
[0032] An inverted filter layer 4 is arranged at one end of the drain hole 21 facing the inclined plate. In this embodiment, the inverted filter layer 4 is made of thick sand and gravel and can be 30 cm thick. The inverted filter layer 4 extends along the retaining plate 2 .
[0033] The embedded bottom structure 3 includes a reinforcing connection structure 31 and a bottom structure 32. One end of the bottom structure 32 is fixed to the inner side of the retaining plate 2, and the other end extends away from the retaining plate 2 with the ends extending upward and downward to form hooks.
[0034] The embedded bottom structure 3 is cast with concrete and a steel frame is placed inside to enhance the structural strength. The embedded bottom structure 3 is cast first, and after it solidifies, the side facing the retaining board 2 is roughened before casting. If necessary, the steel frame in the embedded bottom structure 3 extends to the casting position of the retaining board 2, and is cast together when the retaining board 2 is cast to increase the connection strength.
[0035] In order to prevent the embedded bottom structure 3 from affecting the downward penetration of rainwater, the embedded bottom structure 3 is multiple and distributed along the length direction of the retaining plate 2, and two adjacent embedded bottom structures are separated from each other.
[0036] The filter layer 4 extends along the inner wall of the retaining plate 2 and extends to the curved surface of the reinforced connection structure 31 .
[0037] According to the above configuration, the present application can utilize the drainage holes 21 to accelerate the drainage of rainwater in the soil, and can utilize the deadweight of the soil to press on the embedded bottom structure 3. The higher the humidity, the tighter the pressure is, so as to reduce the probability of the retaining plate 2 being destroyed when the bottom leverage is small and the thrust is large.
[0038] An anchor rod 5 is fixed to one end of the submerged structure 32 away from the retaining plate. The upper end of the anchor rod 5 extends into the submerged structure 32 and the lower end is inserted into the pre-drilled anchor hole, and then fixed in the soil by pouring concrete. A steel frame is built into the submerged structure 32, and the upper end of the anchor rod 5 is fixedly connected to the steel frame by binding with wire.
[0039] A plurality of sub-pipes are fixed in the drainage hole 21 by welding, and the plurality of sub-pipes can be distributed in a plum blossom shape and fixed to the inner wall of the drainage hole 21. By this arrangement, the material selection requirements of the filter layer 4 can be relatively reduced, for example, the size of the pebbles can be relatively reduced.
[0040] In order to further reduce the probability of the retaining plate 2 being damaged, the retaining plate 2 includes a concrete structure and a steel mesh cast and fixed in the concrete structure. There are two steel meshes and they are distributed along the thickness direction of the concrete structure. The steel mesh includes a plurality of mutually parallel transverse bars 22 and a plurality of mutually parallel longitudinal bars 23. The longitudinal bars 23 are vertically fixed to the inner side of the transverse bars 22, and the two can be fixed by binding with iron wire; a plurality of S-shaped tie bars 24 are arranged between the steel meshes, and the two ends of the S-shaped tie bars 24 are respectively hooked on the longitudinal bars 23 opposite to the two steel meshes, and are fixed by welding.
[0041] According to the above arrangement, the steel bar structure of the retaining plate 2 is simpler to construct, and they are pulled against each other to form a whole, so the overall impact resistance is greater.
[0042] In order to reduce the probability of mutual misalignment and fracture between the retaining plate 2 and the anti-sliding pile 1, the end of the transverse reinforcement 22 extends into the anti-sliding pile 1, and the transverse reinforcement 22 is pre-placed in the anti-sliding pile 1 when the anti-sliding pile 1 is cast; the end of the transverse reinforcement 22 is bent.
[0043] Before pouring the retaining plate 2, the surface of the anti-sliding pile 1 facing the retaining plate 2 is roughened in advance to form a roughened surface, so as to strengthen the connection strength between the retaining plate 2 and the anti-sliding pile 1 when the concrete of the retaining plate 2 is poured later.
[0044] In one embodiment of the application, in order to prevent the filter layer 4 from being lost from the upper part, a clay backfill structure 25 is laid on the inner side of the upper end of the retaining plate 2. The clay backfill structure 25 needs to be compacted and a foundation cushion layer 6 is laid underneath it.
[0045] The base cushion layer 6 includes multiple layers of geotextiles, several sand and gravel layers distributed between the geotextiles, and a structural soil layer. The base cushion layer 6 is located on the upper part of the filter layer 4; the sand and gravel (graded stone) layers and the structural soil layer (i.e., sand and soil) are alternately distributed and separated and wrapped with geotextiles.
[0046] The base cushion layer 6 can be used to prevent the clay from seeping downwards and being lost.
[0047] In one embodiment of the present application, the present application also includes an observation pipe 7, which is vertical to the clay backfill structure 25 and inserted into the filter layer 4; the lower end of the observation pipe 7 is closed and a plurality of water-permeable holes are opened in the pipe wall, and the outer wall of the observation pipe is covered with a filter layer 71, which can be a geotextile and is tied with iron wire, that is, the installation process is actually pre-buried rather than driven in.
[0048] The upper end of the observation tube 7 extends out of the clay backfill structure 25 and is threadedly connected to the top cover 72. A float 8 is arranged in the observation tube 7. The float 8 is a hollow closed plastic ball and is fixed with a benchmark 81. The benchmark 81 penetrates the top cover 72 upward and is slidingly connected to the top cover 72. The surface of the benchmark 81 has different color layers, for example: multiple colors and one color for one section, and multiple colors are distributed vertically.
[0049] According to the above arrangement, it is convenient for relevant staff to understand the water content of the soil during inspection. After all, it is difficult to observe other differences when the drainage holes 21 are increased when the water volume is sufficient.
[0050] In one embodiment of the present application, a pressure plate 82 is fixed on the benchmark 81, the pressure plate 82 is annular and is located in the observation tube 7, and a micro switch 9 (waterproof type) is fixed on the inner top surface of the top cover 72. The micro switch 9 is electrically connected to an alarm, for example: the normally open series alarm of the micro switch 9 is connected to an adapted battery, and whether the alarm is sounded is determined by whether the micro switch 9 is pressed; the alarm can be an audible and visual alarm or a more advanced chip motherboard with a 4G module. The chip motherboard can be set to send information to a designated online platform through the 4G module after power-on, so that the present application can promptly issue reminders to surrounding personnel or designated units when the water content in the soil is very high, so as to facilitate relevant units to carry out prevention work.
[0051] It will be appreciated that solar panels may be provided near the slope to charge the batteries if necessary.
[0052] A limit block 721 is also fixed to the inner top surface of the top cover 72 to prevent the micro switch 9 from being crushed. The limit block 721 matches the height of the micro switch 9, and both are located on the moving path of the pressure plate 82.
[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
