[0021] The technical solutions in the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] Example 1, please refer to Figures 1-8 A recyclable temporary support assembly for civil engineering includes a support base 1, a connecting plate 2, a top plate 3, and a connecting plate 4. The support base 1 and the top plate 3 are connected by the connecting plate 2. The upper and lower parts of both sides of the connecting plate 2 are respectively installed and fixed to the support base 1 and the top plate 3 by the connecting plate 4. The top of the top plate 3 is rotatably connected to a ramp plate 5, and a collection box 6 is fixedly installed on the front outer wall of the ramp plate 5.

[0023] The collection box 6 is equipped with a quick-opening and slow-closing component 7, which includes a support plate 706 disposed inside the collection box 6.

[0024] The quick-opening and slow-closing component 7 also includes a slide groove 10 that runs through the middle of the front side of the ramp plate 5. A slider 701 is slidably connected to the inner wall of the slide groove 10, and limit blocks 702 are fixedly connected to the left and right side walls of the slider 701. Limit grooves 11 are symmetrically opened on the inner wall of the slide groove 10 corresponding to the limit blocks 702. The outer wall of the limit blocks 702 slides in contact with the inner wall of the limit grooves 11. Tension springs 703 are fixedly connected to the top of both limit blocks 702, and the top of the tension springs 703 is fixedly connected to the top inner wall of the limit grooves 11. A pressure sensor 704 is fixedly installed on the top of the slider 701. A rotating shaft 705 is rotatably connected to the end of the slider 701 that extends out of the slide groove 10.

[0025] In this embodiment, when assembling and using this component, the support base 1 is first moved to the position where support is needed, and then inserted into the soil to complete the fixation. Next, the appropriate number of connecting plates 2 is selected according to the depth of the foundation pit. Then, the upper and lower parts of the two sides of the connecting plates 2 are bolted to the support base 1 and the top plate 3 respectively through the connecting plates 4. Finally, the top of the top plate 3 is rotatably connected to the ramp plate 5, and the front outer wall of the ramp plate 5 is fixedly installed with a collection box 6. Under normal circumstances, the rotatable connection between the ramp plate 5 and the top plate 3 is horizontally fixed by other torsion springs 709. After the ramp plate 5 is adjusted to the current horizontal angle of the ramp, the rebound force of the torsion springs 709 is used to achieve the close fit between the ramp plate 5 and the ramp. By changing the number of connecting plates 2, this device can support foundations of different heights and can be reused in the construction environment.

[0026] After installation, in normal operation, a slider 701 is slidably connected to the inner wall of the slide groove 10, and limit blocks 702 are fixedly connected to the left and right side walls of the slider 701. Limit grooves 11 are symmetrically formed on the inner wall of the slide groove 10 corresponding to the limit blocks 702, and the outer wall of the limit block 702 slides in contact with the inner wall of the limit groove 11. This allows for stable lifting and lowering of the slider 701 through the cooperation of the limit blocks 702 and the limit grooves 11. Then, a [missing information - likely a device or mechanism] is fixedly connected to the top of each of the two limit blocks 702. A tension spring 703 is fixedly connected to the top inner wall of the limiting groove 11. A pressure sensor 704 is fixedly installed on the top of the slider 701. Under normal conditions, the slider 701 can be pulled by the elastic force of the tension spring 703 to the highest point of the slide groove 10. The elastic force can also be used to maintain a certain degree of compression pressure on the pressure sensor 704 at the highest point of the slide groove 10. That is, when the pressure of the pressure sensor 704 is not lower than a certain value, it will remain in a non-alarm state.

[0027] When a stone rolls onto the support plate 706, a rotating shaft 705 is rotatably connected to one end of the slider 701 extending from the chute 10. This allows the support plate 706 to collect the fallen stone in conjunction with the collection box 6. Under the influence of the stone's gravity, the support plate 706 will cause the slider 701 to move downwards, thus preventing the highest point of the chute 10 from pressing against the pressure sensor 704 and immediately triggering an alarm. When the stone falls occasionally, after the alarm is triggered, workers can manually remove and restore the alarm after confirming safety through observation. This avoids keeping the alarm running for a long time when only a small number of stones fall, which could lead to desensitization.

[0028] Next, when a large number of rocks fall in a short period of time, to avoid the risks of manual intervention, two sliding columns 708 are first fixedly connected to the left and right side walls of the support plate 706 at their near ends. The left and right side walls of the collection box 6 are provided with guide grooves 12 through the sliding columns 708, and the outer wall of the sliding column 708 is slidably connected to the inner wall of the guide groove 12. The lower inner wall of the guide groove 12 is arc-shaped. By using the cooperation of the sliding column 708 and the guide groove 12, the vertical guide groove 12 can restrict the support plate 706 before a suitable weight of rocks is collected, preventing it from flipping. When a suitable weight is collected, the arc-shaped groove at the bottom of the guide groove 12 can automatically release the restriction on the support plate 706. At this time, under the weight of a large number of rocks, when the support plate 706 can rotate, the large pressure can cause the support plate 706 to flip instantly when it is opened, achieving the effect of quickly emptying a large number of rocks.

[0029] Next, to provide a better time window for the complete removal of the crushed stones, reduce the probability of abnormal continuous alarms, and reduce manual intervention, torsion springs 709 are symmetrically arranged on the outer wall of the rotating shaft 705. The two torsion springs 709 are respectively fixedly connected to the left and right side walls of the slider 701 at their close ends, and respectively fixedly connected to the inner wall of the groove 707 at their far ends. The left and right side walls of the slider 701 are fixedly connected to the buffer cylinder 710, and the buffer rods 711 are slidably connected inside the buffer cylinder 710. One end of each of the two buffer rods 711 extends through the inside of the buffer cylinder 710 to the outside, and the extended ends of the two buffer rods 711 are respectively fixedly connected to the inner wall of the groove 707. Thus, during normal flipping and emptying, the torsion springs 709 can be twisted and stored. After the initial impact of a large number of falling stones ends, the torsion springs 709 will drive the support plate 706 to flip back to its original position.

[0030] At this time, a buffer cylinder 710 is fixedly connected to the left and right side walls of the slider 701, and a buffer rod 711 is slidably connected inside the buffer cylinder 710. One end of each buffer rod 711 extends through the inside of the buffer cylinder 710 to the outside, and the extended ends of the two buffer rods 711 are fixedly connected to the inner wall of the groove 707. One end of the buffer rod 711 is fixedly connected to a piston 712, and the inner wall of the piston 712 is slidably connected to the inner wall of the buffer cylinder 710. Through holes 713 are equidistantly opened on the surface of the piston 712. When the support plate 706 is flipped back to its original position, the piston 712 inside the buffer cylinder 710 will be moved by the buffer rod 711. The hydraulic oil in the buffer cylinder 710 will be squeezed and pushed by the through holes 713 with smaller diameters on the surface of the piston 712. The hydraulic resistance will be used to achieve slow closing, providing a time window for the complete removal of the crushed stone, reducing the probability of abnormal continuous alarms, reducing manual intervention, and ensuring the continuity of construction.

[0031] Next, to avoid significant resistance affecting the venting speed during the venting process, through holes 714 are provided at equal intervals on the surface of piston 712. The diameter of through hole 714 is larger than that of through hole 713, and a one-way valve 715 is fixedly installed on the inner wall of through hole 714. Thus, during the venting process, the cooperation between through hole 714 and one-way valve 715 can provide an additional hydraulic oil flow channel, avoiding significant resistance during the venting process.

[0032] In Example 2, based on the above examples, auxiliary blocking components 8 are provided on the left and right side walls of the collection box 6.

[0033] Furthermore, the auxiliary blocking component includes a blocking plate 801 that is slidably disposed on the collection box 6.

[0034] The auxiliary blocking components also include through slots 13 extending through the left and right side walls of the collection box 6. The outer wall of the blocking plate 801 slides and matches the inner wall of the through slot 13. Support blocks 802 are fixedly connected to the left and right side walls of the collection box 6. The outer wall of the rotating rod 803 is slidably connected to the inner wall of the support block 802. A slider 804 is fixedly connected to one end of the rotating rod 803. A limiting groove 805 is opened on one side of the outer wall of the slider 804 corresponding to the sliding post 708. The outer wall of the sliding post 708 is slidably connected to the inner wall of the limiting groove 805. The outer walls of the two limiting grooves 805 that are close to each other slide and fit against the left and right side walls of the collection box 6 respectively.

[0035] In this embodiment, when the support plate 706 moves down normally, the outer wall of the blocking plate 801 slides and matches the inner wall of the through groove 13. The left and right side walls of the collection box 6 are fixedly connected to the support block 802. The outer wall of the rotating rod 803 is slidably connected to the inner wall of the support block 802. One end of the rotating rod 803 is fixedly connected to the slide bar 804. A limiting groove 805 is opened on one side of the outer wall of the slide bar 804 corresponding to the slide column 708. The outer wall of the slide column 708 is slidably connected to the inner wall of the limiting groove 805, so that the slide column 708 can move up and down normally in the limiting groove 805 without causing the rotating rod 803 to move laterally.

[0036] When the support plate 706 is flipped open, the arc-shaped groove drives the sliding column 708 to move laterally to a certain extent, thereby synchronously driving the rotating rod 803 to move laterally. At this time, a transmission gear 806 is provided on the outer wall of the end of the rotating rod 803 away from the sliding bar 804. The bottom of the blocking plate 801 is provided with toothed grooves 807 at equal intervals corresponding to the transmission gear 806, and the outer wall of the transmission gear 806 meshes with the inner wall of the toothed grooves 807. A spiral groove 808 is provided on the outer wall of the end of the rotating rod 803 away from the sliding bar 804, and the inner wall of the transmission gear 806 is fixedly connected to the spiral groove 808. The ball bearing 809 has its outer wall sliding against the inner wall of the spiral groove 808. Through the cooperation between the spiral groove 808 and the ball bearing 809, the rotating rod 803 can restrict the lateral movement of the transmission gear 806 by using the tooth groove 807 when it moves laterally. This causes the transmission gear 806 to rotate in place, thereby driving the baffle plate 801 to move. The two baffle plates 801 are combined and closed from the top of the collection box 6 to form a physical isolation layer. This layer can block and buffer falling stones during the stone discharge window period, preventing direct threats to personnel and equipment below and ensuring construction safety.

[0037] In Example 3, based on the above examples, the left and right side walls of the collection box 6 are provided with a shaking and stone-discharging component 9.

[0038] Furthermore, the shaking stone-discharging component 9 includes a stop bar 902 that presses against the outer wall of the front side of the baffle plate 801.

[0039] The shaking and stone-discharging component 9 also includes a second support block 901 fixedly connected to the left and right side walls of the collection box 6. The outer wall of the abutment rod 902 is slidably connected to the inner wall of the second support block 901. A spring 903 is attached to the outer wall of the first support block 802, and one end of the spring 903 is fixedly connected to the front outer wall of the second support block 901. The other end of the spring 903 is fixedly connected to a mounting plate 904. The outer wall of the mounting plate 904 facing the second support block 901 is fixedly connected to the end of the abutment rod 902 away from the blocking plate 801. The front outer wall of the blocking plate 801 is provided with slots 905 at equal intervals corresponding to the abutment rod 902, and the end of the abutment rod 902 facing the blocking plate 801 is inclined.

[0040] In this embodiment, a spring 903 is fitted to the outer wall of support block 1 802, and one end of the spring 903 is fixedly connected to the front outer wall of support block 2 901. The other end of the spring 903 is fixedly connected to a mounting plate 904, and the outer wall of the mounting plate 904 facing support block 2 901 is fixedly connected to the end of the abutment 902 away from the blocking plate 801. The front outer wall of the blocking plate 801 has slots 905 at equal intervals corresponding to the abutment 902, and the end of the abutment 902 facing the blocking plate 801 is inclined. This allows the support plate 706 to be flipped back into its original position when it is rotated back into its original position. The support plate 706 can contact the surface of the abutment rod 902 through several slots 905 on the side wall of the baffle plate 801. The inclined plane and the spring 903 work together to form a return resistance, causing the support plate 706 to continuously pause and shake when it is rotated back into its original position. This removes any residual gravel that may remain on the surface of the support plate 706, preventing the weight of the residual gravel from causing the support plate 706 to fail to return to its original position and causing continuous false alarms. It also eliminates the mechanical wear caused by gravel jamming, thereby further ensuring the continuity of construction.

[0041] The working principle of this invention is as follows: First, the support base 1 is moved to the position where support is needed, and then it is inserted into the soil to complete the fixation. Next, the appropriate number of splicing connecting plates 2 is selected according to the depth of the foundation pit. The upper and lower parts of the connecting plates 2 are bolted to the support base 1 and the top plate 3 respectively through the connecting plates 4. Finally, the slope plate 5 is adjusted to the horizontal angle of the current slope and the rebound force of the torsion spring 709 is used to achieve the fit between the slope plate 5 and the slope. Then, when a stone rolls down onto the support plate 706, the support plate 706 and the collection box 6 work together to collect the stone. Under the influence of the stone's gravity, the support plate 706 will move the slider 701 downward, so that the highest point of the chute 10 will no longer press against the pressure sensor 704, thereby immediately triggering an alarm. When the stone falls occasionally, after the alarm is triggered, the worker can manually remove and restore it after observing and confirming that it is safe. This avoids keeping the alarm on for a long time when a small number of stones fall, which could lead to alarm paralysis. Then, when a large number of rocks fall in a short period of time, in order to avoid the risk of manual intervention, the sliding column 708 and the guide groove 12 are used to restrict the support plate 706 before the appropriate weight of the falling rocks is collected, so as to prevent it from flipping. After the appropriate weight is collected, the arc groove at the bottom of the guide groove 12 can automatically release the restriction on the support plate 706. At this time, under the weight of a large number of falling rocks, when the support plate 706 can rotate, the large pressure can cause the support plate 706 to flip instantly when it is opened, so as to achieve the effect of quickly emptying a large number of falling rocks. Next, it provides a better time window for the complete removal of crushed stones, reduces the probability of abnormal continuous alarms, and reduces manual intervention. During normal evacuation, the torsion spring 709 can be twisted to store energy. After the initial impact of a large number of falling rocks ends, the torsion spring 709 will drive the support plate 706 to flip back to its original position. At this time, the buffer rod 711 will drive the piston 712 located in the buffer cylinder 710 to move. The piston 712 will use several small-diameter through holes 713 on its surface to squeeze and push the hydraulic oil in the buffer cylinder 710. The hydraulic resistance will be used to achieve slow closure, providing a time window for the complete removal of crushed stones, reducing the probability of abnormal continuous alarms, reducing manual intervention, and ensuring the continuity of construction. To avoid excessive resistance affecting the discharge speed during the evacuation process, a second through hole 714 is provided at equal intervals on the surface of the piston 712. The diameter of the second through hole 714 is larger than that of the first through hole 713, and a one-way valve 715 is fixedly installed on the inner wall of the second through hole 714. Thus, during the evacuation process, the cooperation between the second through hole 714 and the one-way valve 715 can provide an additional flow channel for hydraulic oil, avoiding excessive resistance during the evacuation process. When the support plate 706 is flipped open, the arc groove drives the sliding column 708 to move laterally to a certain extent, which in turn drives the rotating rod 803 to move laterally. At this time, through the cooperation of the spiral groove 808 and the ball 809, the rotating rod 803 can use the tooth groove 807 to restrict the lateral movement of the transmission gear 806 when it moves laterally, so that the transmission gear 806 rotates in place, thereby driving the blocking plate 801 to move. The two blocking plates 801 are combined and closed from the top of the collection box 6 to form a physical isolation layer, which can block and buffer the falling stones during the stone discharge window period, avoid directly threatening the personnel and equipment below, and ensure construction safety. Then, when the support plate 706 is flipped back to its original position, it can contact the surface of the abutment rod 902 through several slots 905 on the side wall of the blocking plate 801. With the cooperation of the inclined plane and the spring 903, a return resistance is formed, which makes the support plate 706 continuously pause and shake when it is flipped back to its original position. This removes any residual gravel that may remain on the surface of the support plate 706, and avoids the weight of the residual gravel from causing the support plate 706 to fail to return to its original position and causing continuous false alarms. It also eliminates the mechanical wear caused by gravel jamming, thereby further ensuring the continuity of construction.
