Description

Technical Field

[0001] The present application relates to the field of slope protection technology, and in particular to an ecological protection method for slope construction. Background Art

[0002] During the construction of expressways, it is inevitable to excavate mountains. After the excavation of the mountains, a large amount of exposed soil and rock slopes will usually be formed. Effective ecological protection of the slopes is an important measure to improve the greening effect of the slopes and protect the ecological environment.

[0003] At present, most of the existing slope ecological protection is carried out through the anchor concrete frame beam method. The construction workers first level the slope, then survey the slope and mark the anchor hole position on the slope. Then the construction workers use drilling equipment to drill holes at the marked positions, and then insert the anchor rods and pour concrete into the anchor holes. After the concrete in the anchor holes solidifies and forms, a steel cage is laid on the slope and connected to the anchor rods. The concrete poured at the steel cage position solidifies and forms a frame beam, and the protection construction on the slope is completed.

[0004] Regarding the above-mentioned related technologies, the inventors found that when using the anchor concrete frame beam method to protect the slope, it is necessary to wait for the concrete to solidify before it can play a protective role. The slope usually adopts the "excavation and protection" method. Under the influence of excavation disturbance, the concrete has not solidified, causing the slope to be easily unstable and damaged, affecting the construction progress. Summary of the Invention

[0005] In order to alleviate the problem that when the concrete on the slope is not solidified and formed, the slope is easily unstable and damaged under the influence of excavation disturbance, which affects the construction progress, the present application provides an ecological protection method for slope construction.

[0006] This application provides an ecological protection method for slope construction, which adopts the following technical solutions:

[0007] An ecological protection method for slope construction comprises the following steps:

[0008] S1: Slope excavation: excavate the mountain slope into steps according to construction requirements to form slope step layers;

[0009] S2: Slope survey, survey the slope surface and mark the anchor hole positions and stabilization hole positions on the slope surface;

[0010] S3: Frame beam laying: a frame beam placement groove is opened on the slope surface, and the prefabricated frame beams are laid in the frame beam placement groove in sequence using lifting equipment. Anchors are installed on the frame beams and connected to the frame beams. The anchors pass through the frame beams and are inserted into the opened anchor holes.

[0011] S4: The anchor is secured by inserting the stabilizing member into the stabilizing hole and connecting the stabilizing member to the anchor;

[0012] S5: Grouting, injecting concrete slurry into the anchor holes and stabilization holes;

[0014] S7: Fill the soil layer, fill the nutrient soil layer into each frame beam, and plant green plants in the nutrient soil layer.

[0015] By adopting the above technical solution, the frame beam is first prefabricated in the factory. After the slope is excavated and formed, the construction workers mark the positions of the anchor holes and the stabilization holes after surveying, and then open the anchor holes and the stabilization holes on the slope, and open the frame beam placement groove on the slope, and then use the lifting equipment to place the frame beams one by one in the frame beam placement groove, and then insert the anchor pieces into the frame beams, and then insert the anchor pieces into the anchor holes, and then insert the stabilization pieces into the stabilization holes, and use the stabilization pieces to lock the anchor pieces, and then achieve preliminary protection of the slope, reduce the possibility of the slope becoming unstable and damaged under the influence of the excavation disturbance in front, and reduce the possibility of waiting for the concrete to solidify before it can play a protective role; then pour concrete in the anchor holes and the stabilization holes to improve the connection strength between the anchor pieces, the stabilization pieces and the frame beams.

[0016] Preferably, a connecting hole is opened on the frame beam in step S3, and a plurality of stabilizing holes are opened on the top of each of the slope step layers. The plurality of stabilizing holes located on the same slope step layer are arranged in one-to-one correspondence with the plurality of rows of anchor holes, and the plurality of anchor holes located in the same row are connected to the corresponding stabilizing holes.

[0017] By adopting the above technical solution, when constructing the slope, after placing the frame beam on the frame beam placement groove, align the connection hole on the frame beam with one of its anchor holes, and then insert the anchor into the connection hole, so that the anchor passes through the connection hole and is inserted into the anchor hole below, and the anchor is connected to the frame beam, and then a stabilizing rod is inserted into the stabilizing hole, so that the stabilizing rod connects and locks multiple anchors located in the same column on the stepped layer of the slope, and the frame beam can be tightened, thereby providing preliminary protection for the slope.

[0019] By adopting the above technical solution, a bending portion is provided on both anchor rods. After the anchor rods are inserted into the connecting hole and the anchor hole, the bending portions of the two anchor rods are clamped in the clamping grooves on the frame beam. Then, a stabilizing member is inserted into the stabilizing hole so that the stabilizing member passes between the two anchor rods and is located on the outside of the connecting sleeve, so that the stabilizing member blocks the connecting sleeve, and then the frame beam is locked, so that the frame beam can protect the slope.

[0020] Preferably, the stabilizing member includes a support ring, a support rod, a stabilizing rod and a rotating assembly, the support rod is rotatably connected to the support ring, the stabilizing rod is fixedly connected to the support rod, the stabilizing rod is eccentrically arranged to the support rod, the rotating assembly is connected to the support ring, the rotating assembly is connected to the support rod, and the rotating assembly is used to drive the support rod to rotate.

[0021] By adopting the above technical solution, the support ring is first fixedly connected to the top of the slope step, and then the stabilizing rod and the support rod are inserted into the stabilizing hole, and the eccentrically protruding side of the stabilizing rod is made to face away from the connecting sleeve. Then, the support rod is rotated by the rotating assembly, and the rotation of the support rod drives the stabilizing rod to rotate. The eccentricity of the stabilizing rod can be used to push the connecting sleeve to move toward the inside of the anchor hole, thereby achieving the locking of the frame beam, so that the frame beam can provide preliminary protection for the slope.

[0022] Preferably, grouting holes are provided on the support ring, and the two grouting holes are respectively located on opposite sides of the support rod. The two rotating components include a rotating rod and a locking rod. The rotating rod is fixedly connected to the support rod, and the locking rod is slidably connected to the rotating rod. The locking rod is inserted into one of the grouting holes.

[0023] By adopting the above technical solution, before constructing the slope, the locking rod is inserted into one of the grouting holes to maintain the stability of the support rod and the stabilizing rod during the insertion process; after the stabilizing rod and the support rod are inserted into the stabilizing hole, the support ring is fixedly connected to the top of the slope step, and then the locking rod is pulled out of the grouting hole. The construction personnel can push the supporting rod to rotate by pushing the rotating rod, thereby driving the stabilizing rod to rotate, thereby tightening the connecting sleeve. At this time, the locking rod is inserted into another grouting hole to lock the stabilizing rod and ensure the tightening effect of the frame beam. Subsequently, concrete slurry is injected into the stabilizing hole through the grouting hole where the locking rod is not inserted to complete the construction.

[0024] Preferably, steel rings are provided on the borders on opposite sides of each frame beam, and the steel rings between two adjacent frame beams are bound together by stirrups.

[0025] By adopting the above technical solution, the steel rings on two adjacent frame beams are tied together by stirrups, and then concrete is poured between the two adjacent frame beams.

The steel bar ring is sleeved on the anchor rod, and the blocking plate is used to block the steel bar ring sleeved on the anchor rod.

[0027] By adopting the above technical solution, anchor rods are set on the slope of the frame beam. When installing the frame beam, the steel bar ring is placed on the anchor rod. When bundling the steel bar rings on adjacent frame beams, the steel bar ring can be pulled to the bottom of the blocking plate to achieve the connection between the anchor rod and the steel bar ring. The frame beam can be further fixed and connected by connecting the anchor rod and its corresponding steel bar ring, thereby improving the stability of the frame beam after installation.

[0028] Preferably, a concrete waterproof layer is provided in each of the frame beams, and a nutrient soil layer is laid on the concrete waterproof layer, and the nutrient soil layer is used for planting green plants.

[0029] By adopting the above technical solution, a concrete waterproof layer is laid on the slope inside the frame beam, and a nutrient soil layer is set on the concrete waterproof layer. By planting green plants on the nutrient soil layer, the ecological greening effect of the slope is increased.

A drainage trough is provided on each frame beam, and the drainage troughs of adjacent frame beams located in the same row are connected through water pipes. The drainage troughs on the frame beams located at the top of each slope stepped layer are connected to the water retaining trough at its top, and the drainage troughs on the frame beams located at the lowest end of the slope are connected to the underground drainage pipes under the road surface.

[0031] By adopting the above technical solution, a water retaining trough is set on each slope step. Rainwater falling on each slope step on rainy days is accumulated in the retaining wall below it, and then discharged into the underground drainage pipe through multiple drainage troughs, thereby reducing the amount of rainwater accumulation on the slope step and reducing the possibility of green plants being washed down due to the large water flow on the slope step near the bottom of the slope.

Anchors are then inserted into the frame beam and connected to the frame beam. The anchors are then inserted into the anchor holes. Stabilizers are then inserted into the stabilization holes and the anchors are locked with the stabilization tools. This achieves preliminary protection for the slope and reduces the possibility of the slope becoming unstable and damaged due to the influence of the excavation disturbance ahead.

[0034] 2. By fixing a connecting sleeve on the outside of the two anchor rods and providing a bent portion on the two anchor rods, when the anchor pieces are inserted into the anchor holes, the bent portions of the two anchor rods are engaged with the engaging grooves on the frame beam. Then, a stabilizing member is inserted into the stabilizing hole, and then the stabilizing member is passed between the two anchor rods and located on the outside of the connecting sleeve. Thus, the stabilizing member blocks the connecting sleeve, thereby locking the frame beam and enabling the frame beam to protect the slope.

[0035] 3. By setting the stabilizing rod eccentrically, after inserting the stabilizing rod into the stabilizing hole, the supporting rod is rotated to drive the stabilizing rod to rotate. The eccentricity of the stabilizing rod can be used to push the connecting sleeve to move into the anchor hole, thereby locking the frame beam and enabling the frame beam to provide preliminary protection for the slope.

DETAILED DESCRIPTION

[0045] The following is combined with Figure 1-8 This application is described in further detail.

[0046] The embodiment of the present application discloses an ecological protection method for slope construction.

[0047] Reference Figure 1 、 Figure 2 and Figure 3 , an ecological protection method for slope construction includes the following steps:

[0048] S1: Slope excavation: excavating the mountain into a stepped shape according to construction requirements to form a slope stepped layer 100;

[0049] S2: Slope survey: survey the slope and mark the positions of anchor holes 200 and stabilization holes 300 on the slope;

[0050] S3: Laying the frame beam 600: Opening a frame beam placement groove on the slope surface, laying the prefabricated frame beams 600 in the frame beam placement groove in sequence using a lifting device, inserting anchors 400 on the frame beam 600, and connecting the anchors 400 to the frame beam 600. The anchors 400 pass through the frame beam 600 and are then inserted into the opened anchor holes 200.

[0051] S4: The anchor 400 is secured, and the securing member 500 is inserted into the securing hole 300 to connect the securing member 500 to the anchor 400;

[0052] S5: Grouting: injecting concrete slurry into the anchor hole 200 and the stabilization hole 300;

[0053] S6: Reinforce the frame beam 600 by connecting two adjacent frame beams 600 through stirrups 621, and then pour concrete grouting at the connection between the two frame beams 600;

[0054] S7: Filling the soil layer: Filling the nutrient soil layer 710 into each frame beam 600 and planting green plants in the nutrient soil layer 710 .

[0055] When protecting the slope, the construction workers first level and survey the slope, and then open anchor holes 200, stabilization holes 300 and frame beam placement grooves on the slope according to construction requirements, and then place the frame beam 600 prefabricated in the factory in the frame beam placement groove, and then insert the anchor 400 into the frame beam 600 and the anchor hole 200, and then insert the stabilization member 500 into the stabilization hole 300, and use the stabilization member 500 to lock the anchor 400, thereby achieving preliminary protection of the slope and reducing the possibility of the slope becoming unstable and damaged under the influence of the excavation disturbance in front.

[0056] Reference Figure 2 and Figure 3 In step S3, the frame beam 600 is a rectangular frame beam, and connection holes 610 are opened on the two opposite side frames of the frame beam 600. The two connection holes 610 on the frame beam 600 are arranged in a one-to-one correspondence with the two adjacent anchor holes 200. One of the anchors 400 passes through one of the connection holes 610 and is inserted into the anchor hole 200. Each anchor 400 is clamped with the frame beam 600 through which it passes.

[0057] Reference Figure 2 、 Figure 3 and Figure 4 A plurality of stabilizing holes 300 are provided at the top of each slope step 100. Each stabilizing hole 300 is provided along the inclination direction of its corresponding slope step 100. Each stabilizing hole 300 is connected to a plurality of anchor holes 200 located in the same row on the same slope step 100. When constructing and protecting the slope, frame beams 600 are first laid one by one on each slope step 100. Anchors 400 are then inserted into each frame beam 600. Stabilizing members 500 are then inserted into the stabilizing holes 300. The stabilizing members 500 connect the plurality of anchors 400 in the same row on the same slope step 100. The frame beams 600 are then fixed to the slope, allowing the frame beams 600 to protect the slope.

[0058] Reference Figure 4 、 Figure 5 and Figure 6The anchor 400 includes two parallel anchor rods 410. A connecting sleeve 420 is sleeved on the outer sides of the two anchor rods 410. Both anchor rods 410 are fixedly connected to the connecting sleeve 420. One end of each anchor rod 410 is bent with a bent portion 430. The bent portions 430 of the two anchor rods 410 are located on the same side of the connecting sleeve 420, and the bent portions 430 of the two anchor rods 410 are bent away from each other. Each frame beam 600 is provided with two sets of snap-fit grooves 611. The two sets of snap-fit grooves 611 are arranged in a one-to-one correspondence with the two connecting holes 610 provided on the frame beam 600. Each set of snap-fit grooves 611 includes two snap-fit grooves 611, which are respectively located on either side of their corresponding connecting hole 610. The two snap-fit grooves 611 in the same set correspond in a one-to-one correspondence with the bent portions 430 of the two anchor rods 410 passing through their corresponding connecting holes 610. When constructing the slope, after placing the frame beam 600 in the frame beam placement groove opened in the slope step layer 100, insert the anchor 400, and respectively snap the bent portions 430 on the two anchor rods 410 into their corresponding two snap-in grooves 611, and then insert the stabilizing member 500 to achieve the installation and locking of the frame beam 600.

[0059] Reference Figure 3 、 Figure 5 and Figure 7 The stabilizing member 500 includes a support ring 510, which is provided with a plurality of mounting holes spaced apart about the axis of the support ring 510. The mounting holes are used to insert expansion bolts. A support rod 520 is coaxially inserted through the support ring 510 and is rotatably connected to the support ring 510. A stabilizing rod 530 is fixedly connected to the lower end of the support rod 520. The axis of the stabilizing rod 530 is parallel to the axis of the support rod 520 and is eccentrically arranged relative to the support rod 520. A rotating assembly 540 is provided at the end of the support rod 520 away from the stabilizing rod 530. The rotating assembly 540 is used to drive the support rod 520 to rotate. When in use, first place the support ring 510 above the stabilizing hole 300, and the support ring 510 is coaxially arranged with the stabilizing hole 300, then insert an expansion bolt into each mounting hole, and use the expansion bolt to fix the support ring 510 to the top of the slope step 100, and then rotate the support rod 520 through the rotating assembly 540, and the rotation of the support rod 520 drives the stabilizing rod 530 to rotate. Since the stabilizing rod 530 is eccentrically arranged, the stabilizing rod 530 can push the connecting sleeve 420 inward when rotating, and then the connecting sleeve 420 and the two anchor rods 410 move toward the inside of the anchor hole 200, thereby achieving the tightening of the frame beam 600 and ensuring the protective effect of the frame beam 600 on the slope.

[0060] Reference Figure 5 and Figure 7The rotating assembly 540 includes a rotating rod 541 fixedly connected to the side wall of the support rod 520. The rotating rod 541 is perpendicular to the support rod 520. A locking rod 542 is inserted into the rotating rod 541. The axis of the locking rod 542 is parallel to the axis of the support rod 520. The locking rod 542 is slidably connected to the rotating rod 541 and slides along its own axis. The support ring 510 is provided with two grouting holes 545. The two grouting holes 545 are arranged opposite each other and are adapted to the locking rod 542. The locking rod 542 is fixedly connected to a connecting plate 543. A spring 544 is sleeved on the outer side of the locking rod 542. One end of the spring 544 is fixedly connected to the rotating rod 541, and the other end of the spring 544 is fixedly connected to the connecting plate 543. The spring 544 pulls the locking rod 542 into one of the grouting holes 545. Before the slope is constructed, the spring 544 pulls the locking rod 542 into one of the grouting holes 545. After the frame beam 600 and the anchor 400 of the same row are installed, the support ring 510 is installed on the top of the slope step 100. The locking rod 542 is then pulled out from the grouting hole 545 into which it is inserted. The rotating rod 541 is then pushed to make the rotating rod 541 drive the support rod 520 to rotate. The rotation of the support rod 520 drives the stabilizing rod 530 to rotate. The eccentricity of the stabilizing rod 530 is utilized to stabilize the slope. It is configured to push multiple anchors 400 to slide inward. After the locking rod 542 rotates to the top of another grouting hole 545, the locking rod 542 is inserted into another grouting hole 545 again under the pull of the spring 544, thereby re-locking the support rod 520 to ensure that the stabilizing rod 530 is pressed tightly against the anchors 400 located in the same column; when grouting is required for the stabilizing hole 300 and the anchor hole 200, the staff can grout into the stabilizing hole 300 through the grouting hole 545 where the locking rod 542 is not passed through.

[0061] Reference Figure 2 and Figure 3 A protective concrete layer 800 is poured on top of each stepped slope 100, and the rotating assembly 540 and other mechanisms at the top of the stepped slope 100 are located within the protective concrete layer 800. After the stabilizing member 500 is constructed, the protective concrete layer 800 covers the rotating assembly 540 and other mechanisms at the top of the stepped slope 100, ensuring the smoothness and aesthetics of the slope.

[0062] Reference Figure 1 and Figure 7To further enhance the slope protection, two steel rings 620 are inserted into the two sides of each frame beam 600, located on either side of the connection hole 610. Each steel ring 620 is a rectangular ring and is slidably connected to the frame of the frame beam 600 it is inserted into. The two steel rings 620 on the same frame beam 600 are spaced apart along the length of the frame beam 600 to which they are connected. Two reinforcement holes are provided on the slope surface of each frame beam 600, each of which is penetrated by an anchor rod 630. Construction workers can install and secure the anchor rod 630 by injecting concrete slurry into the reinforcement holes. The two anchor rods 630 are arranged in a one-to-one correspondence with the two steel rings 620 on the same frame beam 600. The end of the anchor rod 630 exposed on the slope surface is fixedly connected to a blocking plate 631. When protecting the slope, the workers fix the frame beam 600 through the anchor 400, and then put the steel ring 620 at the same height on the frame beam 600 on the anchor rod 630 at the same height inside the frame beam 600. Then, the construction workers pull the adjacent steel rings 620 on the two adjacent frame beams 600 in the direction of approaching each other, and then tie the adjacent steel rings 620 on the two adjacent frame beams 600 together through multiple stirrups 621, and then pour concrete between the two adjacent frame beams 600, so that the steel rings on the same row Multiple frame beams 600 are cast as a single unit, enhancing the slope protection. When construction workers pull the steel rings 620 together through the stirrups 621, the end of the steel ring 620 located inside the frame beam 600 fits neatly under the blocking plate 631. The two steel rings 620 are then snapped together to securely connect the anchor rod 630 to the two steel rings 620. The connection between the anchor rod 630 and its corresponding two steel rings 620 further secures the frame beam 600, enhancing the slope protection provided by the frame beam 600. This also improves the ease of connecting the steel rings 620 and the anchor rod 630, eliminating the need to re-tie the steel rings 620 and anchor rod 630 on the frame beam 600.

[0063] Reference Figure 4 、 Figure 6 and Figure 8 To ensure the stability of the connection between the anchor rods 630 and the two steel rings 620, a concrete water-blocking layer 700 is cast on the slope within each frame beam 600. The steel rings 620 and anchor rods 630 within each frame beam 600 are cast within the concrete water-blocking layer 700. The casting of the concrete water-blocking layer 700 increases the stability of the connection between the steel rings 620 and the anchor rods 630 within the frame beam 600. At the same time, the concrete water-blocking layer 700 blocks rainwater, reducing the possibility of rainwater seeping into the rock.

[0064] Reference Figure 4 、 Figure 6 and Figure 8Each frame beam 600 is fixedly connected to a wire mesh 720. The wire mesh 720 is located above the concrete water-blocking layer 700. A nutrient soil layer 710 is laid on top of the concrete water-blocking layer 700. The wire mesh 720 is embedded in the nutrient soil layer 710, which is used to grow plants. Workers can plant in the nutrient soil layer 710, improving the ecological greening effect of the slope. The installation of the wire mesh 720 reinforces the nutrient soil layer 710, and the roots of the planted plants can be wrapped around the wire mesh 720, improving the stability of the plants.

[0065] Reference Figure 4 and Figure 5 In order to improve the drainage capacity of the slope, a retaining wall 660 will be cast on the top of each slope step layer 100, and a retaining groove 670 will be formed between the retaining wall 660 and the slope step layer 100 located above it.

[0066] Each frame beam 600 is provided with two drainage grooves 640. The two drainage grooves 640 are respectively located on the two side beams of the frame beam 600 without the connection holes 610. The two drainage grooves 640 are provided along the length direction of the side beams on which they are provided, and each drainage groove 640 runs through both ends of the frame beam 600 in which they are provided. Two water pipes 650 are connected between adjacent frame beams 600 in the same row. The two water pipes 650 are arranged in a one-to-one correspondence with the two drainage grooves 640 provided on the same frame beam 600. The drainage grooves 640 in the same row on adjacent frame beams 600 in the same row are connected through a water pipe 650. The top of the drainage groove 640 at the top of each slope step 100 is connected to the water retaining groove 670 above it. The drainage groove 640 at the bottom of the slope is connected to the drainage pipe below the road surface through a water pipe 650. On rainy days, after rainwater falls on each slope terrace 100, it flows into the water retaining trough 670 below each slope terrace 100, and then enters multiple drainage troughs 640 connected to the water retaining trough 670, and then flows into the underground drainage pipe through the drainage trough 640, reducing the amount of rainwater accumulation on the slope terrace 100 and reducing the possibility of green plants being washed down due to the large water flow in the slope terrace 100 near the bottom of the slope.

[0067] The implementation principle of the ecological protection method for slope construction in an embodiment of the present application is as follows: during the excavation process of the slope, the construction workers first level the excavated slope to form a stepped shape, and then open anchor holes 200, stabilizing holes 300 and frame beam placement grooves on the slope, and then use lifting equipment to place the frame beams 600 one by one in the frame beam placement grooves, and then insert the anchor pieces 400 into the frame beams 600, and insert the anchor pieces 400 into the anchor holes 200, and then insert the stabilizing pieces 500 into the stabilizing holes 300, and use the stabilizing pieces 500 to lock the anchor pieces 400, and then achieve preliminary protection of the slope, reducing the possibility of the slope becoming unstable and damaged under the influence of the excavation disturbance in front; then concrete is injected into the anchor holes 200 and the stabilizing holes 300, and the stability of the connection to the frame beams 600 is improved, thereby increasing the protection strength of the frame beams 600 to the slope.

[0068] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
