Description

Technical Field

[0001] The invention belongs to the field of slope support, and in particular relates to a slope support device and a support method. Background Art

[0002] The function of slope support is to limit the deformation and damage of the slope and prevent soil collapse and rolling caused by slope instability from causing damage to surrounding buildings, roads, pipelines, etc.

[0003] At present, in areas with poor geological conditions, such as loose soil layers, soft rock layers or steep slopes, anchor rods and protective nets are generally used for protection, which can improve stability and effectively prevent rock rolling and soil landslides.

[0004] The existing anchor rod protection net support mainly drills holes at the edge of the area and embeds the anchor rods into the holes, and then lays an entire protection net in the slope area. The edge of the protection net is connected to the anchor rods, so that the entire slope is within the coverage area of ​​the protection net. Since the slope protection surface is generally not very flat, for some slope areas with uneven surfaces, the protection net will not be able to effectively contact the slope surface to form support in this area, thereby reducing the support effect. In addition, when gravel slides in this area, due to the certain height difference between the protection net and the slope surface, this height difference will make the gravel have a stronger impact force, which will eventually act on the protection net, aggravating the damage of the protection net, and these impact forces will be transmitted to the anchor rods through the protection net, which may cause the anchor rods to loosen and reduce the stability of the entire support device.

[0015] A slope support method based on the above support device includes the following steps:

[0016] S1. Measure and establish a support laying model, calculate the protection area and determine the location of the drilling point based on the actual area of ​​the slope;

[0017] S2. Mechanical drilling is performed in the designated area of ​​the slope according to the established laying model;

[0018] S3, inserting the outer cylinder in the anchoring mechanism into the drilled hole, and rotating the driving screw to make the steel nail extend from the inner part of the outer cylinder and insert into the external soil, thereby completing the installation and fixation of the anchoring mechanism;

[0019] S4, installing the anchoring mechanism and connecting each protection net through the connecting mechanism above the anchoring mechanism, connecting with a corner of the protection net through the hook on the connecting mechanism, and connecting the four adjacent connecting mechanisms to ensure that the protection net is tightened;

[0020] S5. The height of the protective net is adjusted according to the height difference of the local position of the slope.

[0022] Compared with the prior art, the slope support device and support method provided by the embodiment of the present invention have the following beneficial effects:

[0023] 1. When installing the protective net support of the present invention, the anchoring mechanism cooperates with the connecting mechanism. Each protective net is connected by four connecting mechanisms and positioned by the anchoring mechanism, so as to ensure that the protective nets in each small area are independent of each other. The connecting mechanism on the anchoring mechanism can adjust the height according to the soil topography. Compared with the traditional support device that uses a whole large-area protective net to contact the soil surface, which will cause a large terrain difference locally, the present solution adopts a large support formed by splicing small protective nets, which can make the protective net in a small area fit the soil surface as closely as possible, and no large gap will be generated between the protective net and the soil surface. Even if gravel falls in a local area, the energy storage time when the gravel falls can be minimized, thereby reducing the impact damage to the protective net, and the protection stability and safety are better.

[0024] 2. The protective net in the present invention is hooked with the hook on the connector, and the tension of the protective net can be adjusted through the connector, which is convenient for installation. When the protective net in a certain area is damaged and needs to be replaced, the protective net can be partially disassembled and assembled quickly, which facilitates maintenance and reduces maintenance costs.

[0025] 3. In the present invention, multiple main steel ropes can be connected horizontally and vertically between various connectors, so that adjacent connectors form a whole, the connection is tighter, and the firmness of the protection area formed by each protection net is enhanced, and at the same time the entire support area is made more secure. The main steel ropes and the protection net are also connected by snap buckles to increase the traction tension of the protection net, making the protection net more stable.

[0026] 4. After the anchoring mechanism of the present invention is embedded in the hole, the steel nail inside the outer tube can be driven laterally into the soil, thereby improving the positioning effect of the anchoring mechanism and conveniently pulling out the steel nail to replace or repair the entire anchoring mechanism.

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-13 This application is further described in detail.

[0042] Please refer to Figure 1 Figure 4 and Fig. 9 A slope support device includes an anchoring mechanism 1 fixed inside the soil, the anchoring mechanism 1 includes an outer cylinder 101, four sliding holes connected to the inside of the outer cylinder 101 are opened on the outer side wall of the lower half of the outer cylinder 101, a first slide seat 102 is movably arranged inside the sliding hole, a plurality of steel nails embedded in the soil are fixed on the outer side surface of the first slide seat 102, an extrusion seat 103 for driving the first slide seat 102 to extrude is arranged inside the outer cylinder 101, a driving component 104 for controlling the extrusion seat 103 to move up and down and capable of horizontal rotation is arranged on the upper half of the outer cylinder 101, the extrusion seat 103 is driven downward by the driving component 104 to make the first slide seat 102 move outward, so that the steel nails on the outer side surface of the slide seat can be nailed into the soil outside the outer cylinder 101 (mainly hard soil), thereby improving the firmness and stability of the connecting mechanism 4.

[0043] See also Fig.11 and Fig.13 The side of the first slide 102 away from the steel nail is set as an inclined surface, and four top support blocks 103a are set at the bottom of the extrusion seat 103. The bottom end surfaces of the four top support blocks 103a are all set as inclined surfaces that can be movably fitted with the inclined surface of the first slide 102. When the top support block 103a moves vertically downward, its inclined surface will fit with the inclined surface on the first slide 102 and generate a horizontal thrust, so that the corresponding first slide 102 below drives the steel nail to be squeezed out, thereby fixing the whole more firmly in the drill hole.

[0044] See also Figure 8-10The driving component 104 includes a driving screw 1041 rotatably arranged inside the outer cylinder 101 through a bearing, the bottom end of the driving screw 1041 is threadedly connected to a top cylinder 1042, guide blocks 1044 are symmetrically fixed on both sides of the top cylinder 1042, and a guide rod 1045 is movably inserted on the guide block 1044, one end of the guide rod 1045 is fixed on the inner wall of the outer cylinder 101, and a guiding structure for the top cylinder 1042 to move up and down along the axis of the outer cylinder 101 is formed by the guide rod 1045 and the guide block 1044. An annular groove is opened at the upper center position of the extrusion seat 103, and a movable ring 103b is rotatably arranged in the groove, and the movable ring 103b is fixed to the bottom end of the top cylinder 1042. The driving screw 1041 is configured to be hollow inside and open at both ends. A rotating rod 1043 is fixedly provided at the upper center of the extrusion seat 103. The rotating rod 1043 is movably arranged inside the top cylinder 1042 and the driving screw 1041, and the top end of the rotating rod 1043 extends outside the top end of the driving screw 1041, so that the rotating rod 1043 can control the rotation of the extrusion seat 103. Since the top cylinder 1042 is limited by the guide rod 1045 and the guide block 1044 in the axial direction, when the driving screw 1041 rotates, the top cylinder 1042 moves downward to drive the extrusion seat 103 to move downward, so that the four top support blocks 103a at the bottom of the extrusion seat 103 are in contact with the four first slide seats 102 below at the same time, pushing the first slide seats 102 to move outward.

[0045] See also Figure 8-11 as well as Fig.13A slide groove is provided at the bottom of the four first slide seats 102 on the side close to each other, a second slide seat 5 is movably arranged in the slide groove, a return spring 6 is arranged between one side of the second slide seat 5 and the inside of the slide groove, and a guide column 7 is fixedly provided at the bottom of the four second slide seats 5 on the side close to each other. Four arc grooves 8 are provided on the upper part of the extrusion seat 103, and the guide column 7 can be plugged into the arc groove 8. When the anchor mechanism 1 needs to be removed, after the extrusion seat 103 moves down a certain distance and pushes the first slide 102 to the limit position, the first slide 102 no longer moves outward, and continuing to rotate the driving screw 1041 will cause the extrusion seat 103 to continue to move down and the second slide 5 to undergo the same extrusion movement as the first slide 102, causing the second slide 5 to retract into the slide groove, and after reaching the limit position, the extrusion seat 103 finally slides to the bottom of the guide column 7 at the bottom of the second slide 5. At this time, the second slide 5 loses the extrusion of the extrusion seat 103 and rebounds under the action of the return spring 6, causing the guide column 7 to be above the edge of the extrusion seat 103. At this time, the extrusion seat 103 is lifted a short distance under the action of the reverse rotation of the driving screw 1041, which will enable the arc groove 8 on the upper end surface of the extrusion seat 103 to be plugged into the guide column 7 at the bottom of the second slide 5 (the entire rotation process of the driving screw 1041 The middle rotating rod 1043 will not rotate with it. A pointer or other reference object can be provided at the upper end of the rotating rod 1043 to determine whether the internal extrusion seat 103 is offset, so as to prevent the extrusion seat 103 from rotating and offset so that the guide column 7 cannot be aligned and plugged with the arc groove 8 on the upper surface of the extrusion seat 103). At this time, the driving screw 1041 is kept stationary. Since the bottom end of the rotating rod 1043 is fixedly connected to the extrusion seat 103, and the extrusion seat 103 and the top cylinder 1042 can rotate relative to each other, rotating the rotating rod 1043 will cause the extrusion seat 103 to rotate. While the arc groove 8 on the upper surface of the extrusion seat 103 rotates around the axis of the rotating rod 1043, it will continue to generate oblique pressure on the guide column 7. The oblique pressure will cause the guide column 7 to generate a horizontal pulling force along the axial direction, pulling the steel nails nailed into the external soil back into the outer cylinder 101, and then the anchoring mechanism 1 can be pulled out of the soil.

[0046] In order to improve the firmness of the anchoring mechanism 1 after it enters the soil and facilitate subsequent disassembly, after the outer cylinder 101 in the anchoring mechanism 1 is placed in the pre-drilled embedded hole, the driving screw 1041 at the upper end of the outer cylinder 101 can be rotated to move the extrusion seat 103 downward, pushing the first slide 102 to move outward from the outer cylinder 101, so that the steel nails on the outer side of the first slide 102 can be nailed into the hard soil, thereby making the overall firmness better, and when disassembly is required later, a pull-back structure is also provided between the first slide 102 and the extrusion seat 103, which can pull the steel nails out of the soil in conjunction with the rotating rod 1043, and the outer cylinder 101 can be pulled out, making disassembly convenient.

[0047] See also Figure 3-5 A connection mechanism 4 is fixedly installed at the top of the outer cylinder 101, and a protective net 2 is hung between adjacent connection mechanisms 4. The connection mechanism 4 includes a cover plate 401 fixedly arranged at the top of the outer cylinder 101 through a plurality of connection rods 10, a connector 402 is arranged above the cover plate 401, and a driving component 2 403 for controlling the up and down movement of the connector 402 is arranged on the cover plate 401. The connector 402 can be hung with up to four protective nets 2 to form a small supporting protection surface, and the driving component 2 403 can drive the connector 402 to rise and fall, thereby driving the protective net 2 to be as close to the soil surface of the area as possible, shrinking the activity space when the gravel slides, and reducing the energy storage time of the gravel falling on the protective net 2 after sliding, thereby reducing the impact force of the gravel on the protective net 2.

[0048] See also Figure 6 and Figure 7 The connector 402 includes a housing 4021, and four cavities are symmetrically arranged inside the housing 4021. A take-up shaft 4022 is rotatably arranged in the cavity, and a self-locking assembly 4023 is arranged at the bottom end of the take-up shaft 4022. The self-locking assembly 4023 includes a ratchet fixed on the take-up shaft 4022, a pawl is clamped on the ratchet, and a compression spring with one end fixed on the inner wall of the cavity is arranged on the side of the pawl away from the ratchet, and a connecting shaft is fixed on the pawl. The bottom end of the connecting shaft passes through the bottom of the housing 4021 and is provided with an unlocking knob, and the top of the take-up shaft 4022 passes through the top of the housing 4021 and is provided with a take-up knob. A connecting rope 4024 is connected to the take-up shaft 4022, and a hook 4025 is connected to the front end of the connecting rope 4024. Four threading holes are opened on the outer wall of the housing 4021, and the corresponding threading holes are connected to the cavities, and the connecting rope 4024 is movably arranged in the threading holes. After the hook 4025 on the connecting rope 4024 is hooked with a corner of the protective net 2, the take-up shaft 4022 is rotated and locked by the ratchet pawl, and the excess connecting rope 4024 exposed outside the shell 4021 is wound around the take-up shaft 4022, and the protective net 2 is tensioned outward.

[0049] See also Figure 4 and Figure 5The second driving component 403 includes an adjusting screw 4031 rotatably arranged on the cover plate 401, the upper end of the adjusting screw 4031 is threadedly connected to a cable pole 4032, the top of the cable pole 4032 is fixedly connected to the bottom of the shell 4021 of the connector 402, and two limiting rods 4033 are also arranged at the bottom of the shell 4021, and the bottom end of the limiting rod 4033 is movably plugged into the upper end of the cover plate 401 to guide and limit the shell 4021, and the upper solid area of ​​the cable pole 4032 is also provided with threading holes for the main steel rope 3 to enter in the horizontal and vertical directions, and the two threading holes are vertically distributed in different planes at the upper end of the same cable pole 4032. The bottom end of the adjusting screw 4031 is located at the bottom of the cover 401 and is equipped with an adjusting knob. The adjusting screw 4031 is driven to rotate by the adjusting knob. Since the shell 4021 of the connector 402 is limited by the limiting rod 4033, the cable pole 4032 fixed to the bottom of the shell 4021 can move up and down according to the forward and reverse rotation of the adjusting screw 4031, so that the height of the connector 402 and the cable pole 4032 relative to the outer cylinder 101 is adjustable. The connector 402 is connected to the protective net 2, and the cable pole 4032 is connected to the main steel rope 3, so that the protective net 2 and the main steel rope 3 can be adjusted to fit as closely as possible according to the gap between the soil surface and the protection in the area, thereby improving the protective performance of the protective net 2 to the soil.

[0050] In order to reduce the gap between the falling position of gravel and soil and the protective net 2, reduce the impact force of gravel on the protective net 2, and facilitate the subsequent replacement of the damaged protective net 2 and reduce the maintenance cost, the protective net 2 originally formed by a whole large area is divided into pieces of small-area protective nets 2, and the protective nets 2 are connected by connectors 402, and each connection point of the protective net 2 can be adjusted in height according to the height difference of the laying position, so that each laid protective net 2 can fit the soil surface of the protected area as much as possible. The sliding area is lowered, and the effect of converting gravitational potential energy into kinetic energy to impact the protective net 2 is greatly reduced, thereby extending the life of the protective net 2. Furthermore, since each area is divided by a protective net 2 and is independent of each other, the gravel in different areas will only be captured by their own protective net 2, so that the gravel falling from different areas will not gather together during the sliding process to cause an overload burden on the local or even the entire protective net 2, thereby aggravating the damage to the protective net 2. At the same time, when the local protective net 2 is damaged, the protective net 2 can be quickly removed from the connector 402, which allows for quick replacement and saves materials.

[0051] See also Figure 1-3 as well as Fig.12The protective net 2 is formed by interlacing several braided ropes. The corners of the protective net 2 are connected to the hooks 4025 on the connector 402. The four corners of the protective net 2 are connected through four adjacent connectors 402 to form an independent protective surface. The main steel rope 3 is inserted between multiple wire poles 4032 in the horizontal or vertical direction. Multiple double-headed buckles 9 are connected between the main steel rope 3 and the side of the protective net 2. The double-headed buckle 9 includes an integrated injection-molded substrate. The bottom surface of the substrate is provided with a hook groove that can accommodate the braided rope and prevent the braided rope from slipping off. A slope protection area is formed between multiple main steel ropes 3 in the horizontal and vertical directions and multiple protective nets 2.

[0052] In order to improve the firmness of the support plane formed by splicing multiple protective nets 2, the connectors 402 on a straight line are connected by the main steel rope 3, firstly, the anchoring mechanism 1 forms an interactive whole to improve the compressive resistance. At the same time, the main steel rope 3 and the protective net 2 are connected together by a double-headed buckle 9, so that the protective net 2 is subjected to tensioning traction in multiple directions, and the edge of the protective net 2 is reinforced, so that the protective surface formed by the protective net 2 has better support.

[0053] A slope support method applied to the above slope support device comprises the following steps:

[0054] S1. Measure and establish the support laying model, scan the slope through the equipment, and then use BIM technology to establish the construction laying model to determine the location of the drilling point.

[0055] S2. Determine the drilling position in the designated area of ​​the slope by referring to the established laying model, and then drill a hole at the position by means of a drilling device, and make the diameter of the drilled hole slightly smaller than the diameter of the outer cylinder 101, so that the outer cylinder 101 can fit tightly with the drilled hole when inserted.

[0056] S3. Install the anchoring mechanism 1. The outer cylinder 101 in the anchor mechanism 1 is inserted into the opened drill hole, and at the same time, the steel nail is extended from the inside of the outer cylinder 101 and inserted into the external soil by rotating the driving screw 1041, so that the installation and fixation of the anchor mechanism is completed. Specifically, by rotating the driving screw 1041 at the top of the outer cylinder 101, since the top cylinder 1042 is limited in the axial direction by the guide rod 1045 and the guide block 1044, when the driving screw 1041 rotates, the top cylinder 1042 is limited and moved downward, driving the extrusion seat 103 to move downward, so as to contact with the four first slide seats 102 below for driving. It should be noted that when rotating the driving screw 1041, it is necessary to actively keep the rotating rod 1043 at the center position of the driving screw 1041 and it will not rotate while following the extrusion seat 103 to move downward, so that the four first slide seats 102 move outward, thereby pushing the steel nail out of the sliding hole on the outer wall of the outer cylinder 101 and nailing it into the inner wall of the drill hole, so that the anchor mechanism 1 is fixedly connected to the surface layer of the slope. The connection mechanism 4 above the anchor mechanism 1 is connected to a corner of the protection net 2 , and four adjacent connection mechanisms 4 connect the protection net 2 to ensure that the protection net 2 is tensioned.

[0057] S4. The height of the protective net 2 against the ground is adjusted according to the height difference of the local position of the slope. The connector 402 can be adjusted in height on the already fixed anchoring mechanism 1 through the driving component 2 403, so that the protective net 2 is adjusted to fit the surface of the slope soil as much as possible.

[0058] S5. The height of the protective net 2 touching the ground is adjusted according to the height difference of the local position of the slope. By rotating the adjusting screw 4031 on the cover plate 401, since the shell 4021 of the connector 402 is limited by the limiting rod 4033, the wire pole 4032 fixed to the bottom of the shell 4021 can move up and down according to the forward and reverse rotation of the adjusting screw 4031, so that the height of the connector 402 and the wire pole 4032 relative to the outer cylinder 101 is adjustable. The connector 402 is connected to the protective net 2, and the wire pole 4032 is connected to the main steel rope 3. Therefore, according to the gap between the soil surface and the protection in this area, the protective net 2 and the main steel rope 3 can be adjusted to fit as closely as possible, thereby improving the protection performance of the protective net 2 against the soil.
