Description

Technical Field

[0001] The present application relates to the field of construction engineering technology, and in particular to a protective structure for soft foundation slopes in high-cold and rainy areas and a construction method thereof. Background Art

[0002] In the high-altitude and rainy areas of the Qinghai-Tibet Plateau, permafrost is widely distributed. When building roads in these high-altitude and rainy areas, it is often necessary to excavate the roadbed in the permafrost area and repair the slopes on both sides of the road to improve the stability of the road slopes.

[0003] Frozen soil is a type of soil that is very sensitive to ground temperature changes. The freeze-thaw damage of frozen soil makes the slope stability in the frozen soil area worse than that of ordinary slopes, which affects the safety of the road and the subsequent maintenance costs. In addition, after the surface of the roadbed is excavated, the base melts quickly due to the influence of temperature, thus forming a soft foundation, which will increase the risk of slope collapse.

[0004] Due to the large temperature difference between winter and summer, frozen soil occurs at the rear edge of the slope in winter. Frost heave has a compressive loading effect on the lower slope, increasing the sliding force of the lower slope. When the ground temperature rises in summer, the frozen soil in the slope begins to thaw, the underground ice in the frozen soil melts, and the melted water moves downward, increasing the water content of the lower slope and the groundwater level, causing some parts of the slope to transition from an unsaturated state to a saturated state, thereby reducing the anti-sliding force of the slope and reducing the stability of the slope. Since the rear edge of the slope undergoes periodic freezing and thawing every year with the fluctuation of temperature, this periodic repeated loading will eventually cause the overall slope of the slope to slide, causing the slope to slide.

[0005] In the prior art, a longitudinal gravel blind ditch can be set on the slope to drain the water inside the slope, divert the water inside the slope to the road surface, and drain it through other ditches. However, the water in the gravel blind ditch is prone to freezing, which affects the drainage performance of the gravel blind ditch and makes the slope have a greater risk of landslide. Summary of the invention

[0006] In order to improve the stability of soft foundation slopes, the present application provides a protective structure for soft foundation slopes in high-altitude cold and rainy areas and a construction method thereof.

[0007] The present application provides a protective structure for soft foundation slopes in high-cold and rainy areas and a construction method thereof, which adopts the following technical solutions: A protective structure for soft foundation slopes in high-cold and rainy areas, wherein the slope body is located on the side of the soft foundation; It includes a drainage body, a wall foundation and a gabion wall; the slope body is provided with a blind ditch, the blind ditch is used to accommodate the drainage body, and the drainage body is used to discharge the water in the frozen soil layer of the slope body; along the ditch bottom direction away from the blind ditch, the drainage body includes a trough-shaped concrete cushion layer, a crushed stone layer, a gravel layer and an insulation layer in sequence, and the concrete cushion layer is located below the freeze-thaw line; the soft foundation is provided with a foundation pit close to the side of the slope body, the foundation pit is used to accommodate the wall foundation, and the wall foundation is used to support the gabion wall; the gabion wall is composed of a plurality of gabions, and along the slope surface of the slope body, a plurality of gabions are staggered from bottom to top, and the gabion wall covers the drainage body.

[0008] By adopting the above technical solution, an insulation layer is provided above the drainage body, which can reduce the influence of the external temperature on the internal structure of the drainage body, so that a relatively high temperature is maintained inside the drainage body; thereby, in an environment with relatively low temperatures, the risk of water freezing in the gravel layer is reduced, so that the gravel layer retains a flow channel for melted water to flow.

[0009] The gabion wall has a large deadweight, which can resist the downward force of the slope to further reduce the risk of slope collapse. At the same time, the gabion wall can also drain the melted water inside the slope to reduce the water content at the bottom of the slope and reduce the risk of slope collapse.

[0010] In summary: through the coordinated cooperation of drainage bodies and gabion walls, the risk of landslides on soft foundation slopes can be greatly reduced, the stability of soft foundation slopes can be improved, and the overall project quality can be improved.

[0011] Optionally, the thermal insulation layer includes foam concrete and steel bars, and the steel bars are embedded in the foam concrete.

[0012] By adopting the above technical solution, the heat transfer path in the foam concrete is greatly extended, so that the foam concrete has good thermal insulation performance. At the same time, a steel bar is embedded in the insulation layer, and the steel bar and the foam concrete are integrally formed, thereby improving the structural strength and continuity of the insulation layer, and reducing the impact of the gabion wall on the insulation layer.

[0013] Optionally, the blind ditch includes a longitudinal blind ditch and a transverse blind ditch, the longitudinal blind ditch is located on a vertical plane, and the transverse blind ditch is located on a horizontal plane; correspondingly, the drainage body includes a longitudinal drainage body and a transverse drainage body, the longitudinal drainage body is arranged in the longitudinal blind ditch, and the transverse drainage body is arranged in the transverse blind ditch.

[0014] By adopting the above technical solution, the longitudinal drainage body becomes the main drainage channel of the slope body. By adding a transverse drainage body to assist drainage, the infiltration of melt water in the slope body is reduced, so as to further reduce the risk of slope collapse and improve the stability of the soft foundation slope.

[0015] A construction method for a protective structure of a soft foundation slope in a high-cold and rainy area comprises the following steps: Slope construction: repair the slopes on both sides of the soft foundation, and dig blind ditches on the slope surface of the slopes.

[0017] By adopting the above technical solution, the first driving component raises the first pressing plate, and after the first pressing plate falls, the first pressing plate has an impact on the surface of the foam concrete. The impact vibration of the first pressing plate on the foam concrete will break the aggregation state of the bubbles inside the foam concrete, and separate the connected gas channels into a number of closed bubbles, so that the bubbles are evenly distributed in the bottom area of ​​the foam concrete, so as to improve the thermal insulation performance of the insulation layer. On the other hand, the first pressing plate presses the surface of the foam concrete, so that the bubbles in the upper area of ​​the foam concrete escape and burst, thereby improving the density of the upper area of ​​the foam concrete.

[0020] By adopting the above technical solution, the first pressing plate and the second pressing plate rise or fall at different distances, so that the impact force of the first pressing plate and the second pressing plate on the foam concrete is different. Therefore, as the vibrating device moves, the foam concrete interval can be beaten with three different strengths: light, heavy, and light; so as to further improve the density of the foam concrete, and increase the proportion of closed pores and connecting channels inside the foam concrete, so as to further improve the thermal insulation performance of the thermal insulation layer.

[0021] Optionally, along the sliding direction of the first sliding rod, first racks are provided on both sides of the limiting protrusion, and second racks are provided on the groove side walls on both sides of the limiting groove, and the first rack is used to engage with the second rack.

[0022] By adopting the above technical solution, by setting the first rack and the second rack, the first pressing plate and the second pressing plate are made to vibrate back and forth, and the first pressing plate and the second pressing plate also have vertical movement, so that the first pressing plate and the second pressing plate will continue to tap the foam concrete, further increasing the amount of internal closed bubbles formed in the foam concrete, and further improving the thermal insulation performance of the thermal insulation layer.

[0024] By adopting the above technical solution, the foam concrete is vibrated by using the third vibrating assembly, which reduces the construction steps and the work intensity of the staff.

[0025] Optionally, the vibrating rod is provided with a material storage trough, and a discharge port is provided on the bottom wall of the trough of the vibrating rod; the vibrating device also includes a filling assembly, and the filling assembly includes a filling rod, a hopper, a feed pipe and a counterweight block; the filling rod is arranged in the material storage trough, the filling rod is passed through the discharge port, the hopper is fixed on the frame, the hopper is used to store EPS particles, one end of the feed pipe is connected to the hopper, and the other end of the feed pipe is arranged in the material storage trough, and the counterweight block is fixed on the side of the filling rod away from the ground; when the counterweight block abuts against the vibrating rod, the filling rod blocks the discharge port, and the outer periphery of the filling rod is provided with a through notch, the through notch is arranged at the end of the filling rod away from the counterweight block, and when the counterweight block is separated from the vibrating rod, the through notch is passed through the discharge port, and EPS particles are successively passed through the through notch and the discharge port.

[0026] By adopting the above technical solution, when the vibrating rod is inserted into the foamed concrete, the through-notch of the filling rod is arranged through the discharge port; thus, the EPS particles in the storage tank can sequentially pass through the through-notch and the discharge port and fall into the foamed concrete around the vibrating rod.

DETAILED DESCRIPTION

[0048] The following is combined with Figure 1 -17 Provide further details of this application.

[0049] The embodiment of the present application discloses a protective structure for a soft foundation slope in a high-cold and rainy area, wherein the slope body 1 is located on the side of the soft foundation 2. Figure 1 and Figure 2 The protective structure of the soft foundation slope in the high-altitude and rainy areas includes a drainage body 3, a wall foundation 4 and a gabion wall 5.

[0050] Reference Figure 1 and Figure 2The slope body 1 is provided with a blind ditch 101, which is used to accommodate the drainage body 3, and the drainage body 3 is used to drain the water in the frozen soil layer of the slope body 1. The blind ditch 101 includes a longitudinal blind ditch 111 and a transverse blind ditch 112, the longitudinal blind ditch 111 is located on the vertical plane, and the transverse blind ditch 112 is located on the horizontal plane; correspondingly, the drainage body 3 includes a longitudinal drainage body 31 and a transverse drainage body 32, the longitudinal drainage body 31 is arranged in the longitudinal blind ditch 111, and the transverse drainage body 32 is arranged in the transverse blind ditch 112. In this embodiment, the blind ditch 101 has a trapezoidal cross section; in other embodiments, the blind ditch 101 may also have a rectangular cross section.

[0051] Reference Figure 1 and Figure 2 The transverse blind ditch 112 has a drainage effect on the water inside the slope body 1, and the transverse blind ditch 112 drains the water inside the slope body 1 to the longitudinal blind ditch 111. The longitudinal blind ditch 111 is connected to a natural ditch or an artificial ditch to discharge the water from the slope body 1.

[0052] Reference Figure 3 , the longitudinal drainage body 31 has the same structure as the transverse drainage body 32. This embodiment takes the longitudinal drainage body 31 as an example to explain the specific structure of the drainage body 3. Along the bottom direction away from the longitudinal blind ditch 111, the longitudinal drainage body 31 includes a trough-shaped concrete cushion layer 33, a crushed stone layer 34, a gravel layer 35 and an insulation layer 36 in sequence. Among them, the concrete cushion layer 33 is located below the freeze-thaw line 102. First, the melted water of the frozen soil layer in the slope body 1 flows to the crushed stone layer 34; then, the melted water flows from the crushed stone layer 34 to the concrete cushion layer 33, and finally, the melted water flows along the bottom wall of the trough of the concrete cushion layer 33, so that the melted water in the slope body 1 flows out of the slope body 1.

[0053] Reference Figure 3 In this embodiment, the insulation layer 36 includes foamed concrete 361 and steel bars 362, and the steel bars 362 are embedded in the foamed concrete 361; that is, in this embodiment, the foamed concrete 361 in the insulation layer 36 is cast-in-place to increase the overall height of the longitudinal drainage body 31. In other embodiments, the insulation layer 36 can also be formed by splicing and laying prefabricated foamed concrete 361 panels.

[0054] Reference Figure 3 , Foam concrete 361 is a material made by mixing EPS particles 363 (polystyrene particles) with concrete. EPS particles 363 (polystyrene particles) are a lightweight, closed-cell material with a low thermal conductivity. When EPS particles 363 (polystyrene particles) are mixed into concrete, they form a large number of tiny air chambers inside the concrete. Still air is a poor conductor of heat, and these air chambers can effectively prevent the transfer of heat.

[0055] In the foam concrete 361, the heat must bypass the air chamber formed by the EPS particles 363 (polystyrene particles), which increases the path length of heat conduction, thereby reducing the heat conduction efficiency. Therefore, in the foam concrete 361, the heat transfer path is greatly extended, so that the foam concrete 361 has good thermal insulation performance. At the same time, a steel bar body 362 is embedded in the insulation layer 36, and the steel bar body 362 is integrally formed with the foam concrete 361, thereby improving the structural strength and continuity of the insulation layer 36, so as to reduce the impact of the gabion wall 5 on the insulation layer 36.

[0056] Reference Figure 2 A foundation pit 21 is provided on one side of the soft foundation 2 close to the slope body 1, and the foundation pit 21 is used to accommodate the wall foundation 4, and the wall foundation 4 is used to support the gabion wall 5. In this embodiment, the wall foundation 4 is cast by crushed stone and concrete.

[0057] Reference Figure 2 The gabion wall 5 is composed of a plurality of gabions, and along the slope surface of the slope body 1 , a plurality of gabions are staggered from bottom to top, and the gabion wall 5 covers the drainage body 3 .

[0058] The implementation principle of the protective structure of a soft foundation slope in a high-cold and rainy area in the embodiment of the present application is: Reference Figure 2 and Figure 3 The grooved concrete cushion layer 33 in the drainage body 3 is located below the freeze-thaw line 102, so that the bottom of the gravel layer 34 is also located below the freeze-thaw line 102, reducing the risk of freezing of the water body at the bottom of the gravel layer 34, and allowing the gravel layer 34 to retain a flow channel for liquid water to flow, so that the drainage body 3 can discharge the liquid water melted from the frozen soil layer in time, reduce the infiltration of melted water, reduce the risk of landslide at the bottom of the slope body 1, and improve the stability of the soft foundation 2 slope.

[0059] Meanwhile, after the crushed stone layer 34 is laid, the gravel layer 35 should be laid on the crushed stone layer 34 in time to prevent the external temperature from disturbing the stable state of the soil inside the slope body 1.

[0060] An insulation layer 36 is provided above the drainage body 3 to reduce the influence of the external temperature on the internal structure of the drainage body 3, so that the temperature inside the drainage body 3 is kept relatively high; thus, the risk of freezing of water in the gravel layer 34 is reduced in a low temperature environment, and the gravel layer 34 has a flow channel for melted water to flow. At the same time, the insulation layer 36 also reduces the amplitude of the temperature change of the frozen soil on both sides of the drainage body 3, reduces the freeze-thaw damage of the frozen soil on both sides of the drainage body 3, and facilitates the melted water of the frozen soil layer in the slope body 1 to flow into the drainage body 3.

[0061] The gabion wall 5 has a large deadweight, and can resist the downward force of the slope body 1, so as to further reduce the risk of the slope body 1 sliding down. At the same time, the gabion wall 5 covers the drainage body 3, and the gabion wall 5 has a heat preservation effect on the drainage body 3. The gabion wall 5 can discharge the melted water inside the slope body 1, so as to reduce the water content at the bottom of the slope body 1 and reduce the risk of the slope body 1 sliding down.

[0062] In summary: through the coordinated cooperation of the drainage body 3 and the gabion wall 5, the risk of landslide of the soft foundation 2 slope can be greatly reduced, the stability of the soft foundation 2 slope can be improved, and the overall project quality can be improved.

[0063] The gabion wall 5 is light and easy to install, has simple process and strong adaptability, and can reduce investment costs while ensuring the stability of the slope body 1 in a hot and rainy environment. The gabion wall 5 has the advantage of flexible construction. In the cold and rainy season, there is no need to limit the construction period due to safety considerations, which reduces the labor, equipment rental and other indirect expenses caused by long-term construction.

A roller 65 is provided at the bottom of the frame 6, and the frame 6 is used to move along the length direction of the blind ditch 101. In this embodiment, the slope body 1 is installed with a channel steel 15, and the channel steel 15 is located on both sides of the longitudinal blind ditch 111; the roller 65 at the bottom of the frame 6 is arranged on the channel steel 15, and the channel steel 15 has a guiding effect on the frame 6. The staff can install a winder on the slope body 1, and use the winder to pull the vibrating device, so that the vibrating device moves on the channel steel 15.

[0069] Reference Figure 5 and Figure 6 The first vibrating assembly 7 includes a first sliding rod 71, a first pressing plate 72 and a first magnet 73. The first sliding rod 71 is slidably connected to the frame 6, and the frame 6 is provided with a first sleeve 61 for the first sliding rod 71 to pass through. A first plug-in slot 721 is provided on one side of the first pressing plate 72, and the end of the first sliding rod 71 is arranged in the first plug-in slot 721.

The hoist 81 lifts the first pressing plate 72 to a certain height, and then the hoist 81 unwinds; the first pressing plate 72 falls under the action of gravity, and the first pressing plate 72 collides with the foam concrete 361. The first pressing plate 72 has a compacting effect on the foam concrete 361.

[0071] Reference Figure 5 and Figure 6 The second driving assembly 9 includes a rotating motor 91 and a driving magnet member 92. The rotating motor 91 is fixed on the frame 6, and the driving magnet member 92 is fixed on the driving end of the rotating motor 91. The rotating motor 91 causes the driving magnet member 92 to rotate, so that the N pole and the S pole of the driving magnet member 92 alternately interact with the first magnet member 73; that is, the second driving assembly 9 alternately applies repulsive force and attractive force to the first magnet member 73 to force the first pressing plate 72 to make a small distance reciprocating motion on the surface of the foam concrete 361.

[0072] The implementation principle of the construction method of a protective structure for soft foundation slopes in high-cold and rainy areas in the embodiment of the present application is as follows: Reference Figure 4 and Figure 5 Along the length direction of the foam concrete 361 , the vibrating device moves forward a distance of the first pressing plate 72 each time, and the vibrating device is used to vibrate and compact the foam concrete 361 .

[0073] Refer to 4 and Figure 5 , the first driving assembly 8 raises the first pressing plate 72, and after the first pressing plate 72 falls, the first pressing plate 72 has an impact effect on the surface of the foam concrete 361. On the one hand, the first pressing plate 72 hits the foam concrete 361, and the impact vibration inside the foam concrete 361 can break the aggregation state of the bubbles, and separate the connected gas channels into a number of closed bubbles, so that the bubbles are evenly distributed in the bottom area of ​​the foam concrete 361, so as to improve the thermal insulation performance of the thermal insulation layer 36. On the other hand, the first pressing plate 72 hits the surface of the foam concrete 361, so that the bubbles in the upper area of ​​the foam concrete 361 escape and break, and the density of the upper area of ​​the foam concrete 361 is improved.

[0074] Reference Figure 5 and Figure 6 After the first pressing plate 72 hits the foam concrete 361, the motor in the second driving assembly 9 drives the magnet member to rotate, so that the first magnet member 73 and the driving magnet member 92 alternately generate suction and repulsion, so that the first pressing plate 72 makes a reciprocating linear motion on the surface of the foam concrete 361, so that the first pressing plate 72 vibrates and flattens the foam concrete 361 on the plane. That is, the reciprocating vibration of the first pressing plate 72 is used to remove excess bubbles on the surface of the foam concrete 361, and improve the flatness and smoothness of the surface of the foam concrete 361; and the first pressing plate 72 drives the particles in the surface layer of the foam concrete 361 to vibrate, so as to close the open pores and flow channels in the foam concrete 361, thereby further improving the thermal insulation performance of the thermal insulation layer 36.

[0075] Reference Figure 5 and Figure 6 When the first pressing plate 72 is separated from the foam concrete 361, the second driving assembly 9 causes the first pressing plate 72 to reciprocate along the surface of the foam concrete 361 to reduce the occurrence of roughening on the surface of the foam concrete 361, so that the first pressing plate 72 is smoothly separated from the foam concrete 361.

The limiting protrusion 722 is inserted into the limiting groove 1222. Along the sliding direction of the first sliding rod 71, an avoidance distance is provided between the limiting protrusion 722 and the groove side wall of the limiting groove 1222, and the second pressing plate 122 is used to collide with the foam concrete 361; the second magnet member 123 is fixedly arranged on the side of the second pressing plate 122 close to the second sliding rod 121, and the driving magnetic body is used to force the second magnet member 123 and the second pressing plate 122 to vibrate reciprocatingly.

[0080] Reference Figure 11 to Figure 12 Along the sliding direction of the first sliding rod 71 , first racks 723 are provided on both sides of the limiting protrusion 722 , and second racks 1223 are provided on the groove side walls on both sides of the limiting groove 1222 , and the first rack 723 is used to engage with the second rack 1223 .

[0081] Reference Fig.10 The fourth vibrating assembly 14 includes a fourth linear reciprocating driving member 141, a fourth sliding rod 142 and a fourth pressing plate 143. The frame 6 is provided with a fourth sleeve 64 for the fourth sliding rod 142 to pass through, the fourth sliding rod 142 is slidingly connected to the frame 6, the fourth pressing plate 143 is fixedly connected to the end of the fourth sliding rod 142, the driving end of the fourth linear reciprocating driving member 141 is connected to the first sliding rod 71, the fourth linear reciprocating driving member 141 drives the first pressing plate 72 to abut against the surface of the foam concrete 361, and the fourth pressing plate 143 is used to scrape the foam concrete 361 to improve the smoothness of the surface of the foam concrete 361.

[0082] The implementation principle of the construction method of a protective structure for soft foundation slopes in high-cold and rainy areas in the embodiment of the present application is as follows: Reference Figure 7 In this embodiment, the first pressing plate 72, the second pressing plate 122, the third pressing plate 133 and the fourth pressing plate 143 have the same size, and the vibrating device advances the distance of the first pressing plate 72 each time. For the convenience of subsequent description, an area of ​​the foamed concrete 361 is named as a working area, and the working area of ​​the foamed concrete 361 is successively acted upon by the third pressing plate 133, the second pressing plate 122, the first pressing plate 72, the second pressing plate 122 and the first pressing plate 72.

[0083] Reference Figure 7 and Figure 8 During the forward movement of the vibrating device, the first vibrating assembly 7 is first located above the working area of ​​the foam concrete 361. The vibrating rod 135 of the third vibrating assembly 13 is inserted into the foam concrete 361, and the third pressing plate 133 is in contact with the surface of the foam concrete 361; thus, under the action of the vibrating motor, the third vibrating assembly 13 vibrates the foam concrete 361 to discharge bubbles in the foam concrete 361 and improve the compactness of the foam concrete 361.

[0084] Reference Figure 7Then, the vibrating device moves forward by a first pressing plate 72 distance, so that the second vibrating assembly 12 of the vibrating device is located in the working area of ​​the foamed concrete 361. Then, the vibrating device moves forward by a first pressing plate 72 distance, so that the first vibrating assembly 7 of the vibrating device is located in the working area of ​​the foamed concrete 361. Then, the vibrating device moves forward by a first pressing plate 72 distance, so that the second vibrating assembly 12 of the vibrating device is located in the working area of ​​the foamed concrete 361. Refer to 9 and Fig.11 , the first pressing plate 72 drives the second pressing plate 122 to move, and a clearance distance is set between the limiting protrusion 722 and the limiting groove 1222; so that the first pressing plate 72 and the second pressing plate 122 rise or fall by different distances. Therefore, when the first pressing plate 72 and the second pressing plate 122 fall onto the foam concrete 361, the impact force of the first pressing plate 72 and the second pressing plate 122 on the foam concrete 361 is different. Therefore, as the vibrating device moves, the working area of ​​the foam concrete 361 can be beaten with three different strengths of light, heavy, and light at intervals; so as to further improve the density of the foam concrete 361, and increase the proportion of the closure of the internal pores and connecting channels of the foam concrete 361, so as to further improve the thermal insulation performance of the thermal insulation layer 36.

[0085] Reference Fig.11 and Fig.12 When the first pressing plate 72 and the second pressing plate 122 act on the second driving assembly 9 and make linear reciprocating motion on the surface of the foam concrete 361; the first rack 723 and the second rack 1223 not only mesh with each other, but the first rack 723 and the second rack 1223 will also be relatively close to or relatively far away from each other, so that the first rack 723 will slide along the surface of the second rack 1223, and the first rack 723 and the first pressing plate 72 will be displaced away from the foam concrete 361, so that the first pressing plate 72 will continue to tap the foam concrete 361, further increasing the amount of internal closed bubbles formed in the foam concrete 361, and further improving the thermal insulation performance of the thermal insulation layer 36.

[0086] Example 4 In Example 3, when the vibrating rod 135 vibrates the foamed concrete 361, due to the low density of the EPS particles 363 in the foamed concrete 361, the EPS particles 363 will move away from the vibrating rod 135 and move upward under the action of the vibrating rod 135, so that the content of EPS particles 363 in the foamed concrete 361 around the vibrating rod 135 is low, thereby affecting the thermal insulation performance of the foamed concrete 361 in the vibrating area of ​​the vibrating rod 135. Therefore, this Example 4 further improves the construction method of Example 3.

[0087] The difference between this embodiment 4 and embodiment 3 is that: Reference Figures 13 to 15The vibrating rod 135 is provided with a material storage trough 1351, and a discharge port 1352 is provided on the bottom wall of the trough of the vibrating rod 135; the vibrating device also includes a filling assembly 16, and the filling assembly 16 includes a hopper 161, a feed pipe 162, a filling rod 163 and a counterweight 164; the filling rod 163 is arranged in the material storage trough 1351, the hopper 161 is fixed on the frame 6, the hopper 161 is used to store EPS particles 363, one end of the feed pipe 162 is connected to the hopper 161, and the other end of the feed pipe 162 is arranged in the material storage trough 1351, the filling rod 163 is passed through the discharge port 1352, and the counterweight 164 is fixed on the side of the filling rod 163 away from the ground, and a through notch 1631 is provided on the outer periphery of the filling rod 163, and the through notch 1631 is arranged at the end of the filling rod 163 away from the counterweight 164.

[0088] Reference Figures 13 to 15 Under normal conditions, the counterweight block 164 abuts against the vibrating rod 135 , and the filling rod 163 blocks the discharge port 1352 , so that the EPS particles 363 are stored in the storage tank 1351 .

[0089] Reference Figure 16 to Figure 17 When the vibrating rod 135 is inserted into the foamed concrete 361, the foamed concrete 361 exerts an upward force on the filling rod 163, and the filling rod 163 has an upward displacement, so that the through-notch 1631 is penetrated and arranged at the discharge port 1352. Therefore, the EPS particles 363 in the storage tank 1351 can sequentially pass through the through-notch 1631 and the discharge port 1352 and fall into the foamed concrete 361 around the vibrating rod 135. In particular, when the vibrating rod 135 vibrates the foamed concrete 361, more EPS particles 363 will be scattered from the storage tank 1351 to the concrete at the bottom of the vibrating rod 135; when the vibrating rod 135 vibrates the foamed concrete 361, the above-mentioned EPS foamed concrete 361 will spread around the vibrating rod 135 to be added to the foamed concrete 361 around the vibrating rod 135.

[0090] When the vibrating rod 135 is pulled out of the foam concrete 361 , the counterweight block 164 applies a downward force to the filling rod 163 , and the filling rod 163 moves toward the foam concrete 361 , so that the outer peripheral wall of the filling rod 163 blocks the discharge port 1352 .

[0091] To sum up: through the coordinated cooperation of the third vibrating component 13 and the filling component 16, when the third vibrating component 13 vibrates the foam concrete 361, the filling component 16 will add EPS particles 363 to the foam concrete 361 around the vibrating rod 135 to improve the uniformity of the distribution of EPS particles 363 in the foam concrete 361, reduce the weak areas of thermal insulation performance in the foam concrete 361, and improve the overall thermal insulation performance of the foam concrete 361.

[0092] 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.
