Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of slope reinforcement, in particular to a ring hoop linkage type rock-soil slope protection and reinforcement structure with anti-seepage blind ditch. BACKGROUND

[0002] With the rapid development of infrastructure construction in China, a large number of rock-soil slopes are formed in the fields of highway, railway, water conservancy, mining and urban construction. Under the action of long-term natural weathering, rainfall erosion and external factors such as earthquakes, the internal stress state of these slopes will gradually deteriorate, the rock-soil body strength will decrease, and geological disasters such as landslides, collapses and mudslides will easily occur.

[0003] At present, a variety of mature schemes have been developed for the reinforcement technology of rock-soil slopes, such as anchoring technology, frame beam structure and anti-slide pile. Taking the grouting anchoring technology as an example, its construction process includes drilling, hole cleaning, grouting, waiting for maintenance and other links. Although the above-mentioned schemes are relatively common, they still have some shortcomings.

[0004] Firstly, the cast-in-place concrete frame beam method needs several days or even longer curing time for the hardening of cement mortar, and effective anchoring force cannot be provided during this period. In addition, the traditional grouting anchor rod is a "one-time" concealed engineering, and its internal stress state and damage condition are difficult to detect after construction is completed. When the anchoring section performance decays or even fails due to long-term corrosion, stratum creep and other reasons, it cannot be replaced and repaired in time. SUMMARY

In addition, the traditional grouting anchor rod is a "one-time" concealed engineering, and its internal stress state and damage condition are difficult to detect after construction is completed. When the anchoring section performance decays or even fails due to long-term corrosion, stratum creep and other reasons, it cannot be replaced and repaired in time.

[0010] The support frame is provided with a through slot corresponding to the positions of the reinforcing mechanisms, and the reinforcing mechanism comprises a tensioning assembly penetrating through the through slot and an auxiliary assembly arranged inside the tensioning assembly;

[0011] The tensioning assembly comprises a mounting sleeve penetrating through the through slot and located inside the slope, and the bottom end of the mounting sleeve is provided with a plurality of tensioning blocks in the circumferential direction; during operation, the plurality of tensioning blocks are driven by the auxiliary assembly to expand synchronously outward, so as to realize the locking engagement of the mounting sleeve and the slope.

[0012] Further, the support frame is provided with four and arranged in a rectangular shape along the slope surface, the left and right ends of the upper and lower support frames are provided with sliding grooves, and the through slot is further provided with a linkage groove in the circumferential direction; during installation, the left and right support frames are slid into the corresponding sliding grooves.

[0016] Further, the auxiliary assembly comprises a mounting rod matched and locked with the threaded groove of the mounting sleeve, the bottom end of the mounting rod is fixedly provided with a tapered block matched and contacted with the plurality of tensioning blocks, and the bottom end of the tapered block is fixedly connected with a self-tapping head.

[0043] The support frame 1 is provided with four support frames 1 and is rectangular along the slope surface of the slope 100.

[0044] The four support frames 1 are provided with a linkage plate 14 with an arc-shaped groove 141 arranged on the end surface, and the four linkage plates 14 are provided with a plurality of locking blocks 142 fixedly arranged on the side close to each other.

[0045] The inner wall of the mounting sleeve 211 is provided with a threaded groove 2111, and the bottom end of the mounting sleeve 211 is provided with a plurality of avoidance grooves 2112 arranged in the circumferential direction.

[0046] The linkage member 213 includes a clamping plate 2131 arranged on the top end of the mounting sleeve 211 and closely combined with the support frame 1.

[0047] The auxiliary assembly 22 includes a mounting rod 221 matched and locked with the threaded groove 2111 of the mounting sleeve 211, and the bottom end of the mounting rod 221 is fixedly provided with a tapered block 222 matched and contacted with the plurality of tensioning blocks 212.

[0048] The top end of the mounting rod 221 is fixedly provided with an adjusting top block 224 with a hexagonal groove 2241 opened in the end face, and the adjusting top block 224 is in contact with the plurality of abutting blocks 2133, and in the installation process, the linkage locking of the adjacent support frames 1 is realized through the cooperation of the adjusting top block 224 and the plurality of abutting blocks 2133.

[0049] The circumferential outer surface of the mounting sleeve 211 in the space surrounded by the four linkage plates 14 is provided with a plurality of locking grooves 2115 engaged with the locking blocks 142, and the mounting sleeve 211 provided with the locking grooves 2115 is provided with a clamping piece 225, and the clamping piece 225 is rotatably sleeved on the circumferential outer surface of the corresponding position mounting sleeve 211.

[0050] The clamping piece 225 comprises an adjusting disc 2251 rotatably connected with the mounting sleeve 211, and a plurality of circular rods 2253 distributed in the circumferential direction are fixedly arranged on the adjusting disc 2251, and a connecting block 2252 is arranged on the side of each circular rod 2253 away from the adjusting disc 2251, and the adjusting disc (2251) is provided with a threaded hole 2254 penetrating the connecting block 2252 at a position corresponding to the plurality of circular rods 2253.

[0051] In specific work:

[0052] At present, in some special working scenes (such as rock cutting slope of highway and railway), the cast-in-place concrete frame beam is used, and the cement mortar needs to be cured and hardened for several days or even longer curing time, so that effective anchoring force cannot be provided during this period. In addition, the traditional grouting anchor rod is a "one-time" concealed engineering, and once the construction is completed, the internal stress state and damage condition are difficult to detect, and when the anchoring section performance decays or even fails due to long-term corrosion, ground creep and other reasons, it cannot be replaced and repaired in time. Based on this, the annular hoop linkage type rock and soil slope protection and reinforcement structure with anti-seepage blind ditch does not need concrete mixing, pouring and curing, can bear stress immediately after installation, can greatly shorten the construction period, and can also check or replace the invalid unit regularly.

[0053] Specifically, when the slope 100 needs to be reinforced, first, drill holes on the slope 100 for placing the installation sleeve 211 (the drilling of the plurality of receiving holes is the same as the installation position of the four support frames 1, that is, in a rectangular shape, and a receiving hole is also provided at the center of the slope 100), after the receiving hole is opened, the plurality of installation sleeves 211 are sequentially inserted through the through slot 11 and the receiving hole, and the bottom end of the installation sleeve 211 is in contact with the bottom end of the receiving hole, then, the two support frames 1 along the front and rear direction are placed corresponding to the position of the receiving hole (as mentioned above, the installation sleeve 211 has been placed in the receiving hole, and the support frame 1 is placed in the process, the installation sleeve 211 passes through the through slot 11, and the preliminary clamping work between the support frame 1 and the installation sleeve 211 is realized through the clamping plate 2131, specifically, the clamping plate 2131 is divided into a fixed section fixedly connected with the installation sleeve 211, and two clamping blocks provided on the fixed section, the support frame 1 is provided with a matching groove corresponding to the position of the clamping plate 2131, and the clamping plate 2131 enters the matching groove during placement, and because the clamping block and the matching groove have the same shape, the preliminary clamping work of the installation sleeve 211 is realized through the cooperation of the matching groove and the clamping plate 2131, to avoid rotation in the subsequent work).

[0054] After the placement of the two support frames 1 is completed, the installation rod 221 is screwed into the two installation sleeves 211 in the middle to further lock the installation sleeve 211, the installation rod 221 and the rock slope 100 (specifically, the bottom end of the installation rod 221 is fixedly provided with a tapered block 222, when the installation rod 221 is screwed into the installation sleeve 211 through the cooperation of the driving tool and the hexagonal groove 2241, the tapered rod gradually contacts the plurality of tensioning blocks 212 during the process, the plurality of tensioning blocks 212 are expanded synchronously and compressed the compression spring 2114 when sliding along the respective sliding rod 2113, continue to screw the installation rod 221, the plurality of tensioning blocks 212 are completely stretched out and tightly engaged with the inner wall of the receiving hole, in this way, the clamping work of the installation sleeve 211 and the rock soil is realized through the expansion of the plurality of tensioning blocks 212, it should be noted that a plurality of recesses are provided on the side of the plurality of tensioning blocks 212 close to the rock soil layer, which is to increase the friction between the tensioning block 212 and the rock soil layer after the expansion, thereby improving the stability of the engagement, at the same time, the bottom end of the tapered rod is fixedly provided with a self-tapping head 223, the self-tapping head 223 is rotated synchronously while the tapered block 222 expands the plurality of tensioning blocks 212, and gradually breaks the rock soil layer to realize the engagement with the rock soil layer, further improving the stability of the engagement between the mechanism and the slope 100).

[0055] It needs explanation that a plurality of linkage grooves 13 are arranged along the circumferential direction in the through groove 11, and a plurality of abutting blocks 2133 are arranged along the circumferential direction on the bearing seat 2132. When the mounting rod 221 is screwed into the inside of the mounting sleeve 211, the mounting sleeve 211, the mounting rod 221 and the rock-soil slope 100 can be stably engaged, and the mounting rod 221 and the support frame 1 can be cooperatively locked by adjusting the cooperation between the abutting blocks 2133 and the adjusting top block 224. Specifically, the abutting blocks 2133 are arranged in the bearing seat 2132 by a compression spring. During the movement of the adjusting top block 224, the outer wall of the adjusting top block 224 gradually contacts and cooperates with the abutting blocks 2133. At this time, the compression spring is compressed under stress, and the abutting blocks 2133 are simultaneously pushed out and then enter the inside of the corresponding linkage groove 13 (at this time, the adjusting top block 224 is attached to the top end of the support frame 1). Through the single rotation of the mounting rod 221, the mounting sleeve 211, the mounting rod 221, the rock-soil layer and the support plate can be locked. This can simplify the installation process, and through a series of linkage, the above components are connected into a whole, thereby effectively improving the stability of the installation.

[0056] After the linkage and locking work of the middle positions of the two support frames 1 are completed, the left and right support frames 1 are respectively slid into the sliding grooves 12 (since the above installation process only achieves the locking work of the middle positions of the upper and lower support frames 1, the left and right support frames 1 will not be blocked during the sliding process). After the preliminary placement of the left and right support frames 1 is completed, the above installation steps are repeated to achieve the installation and locking work of the middle positions of the left and right support frames 1. Then, the reinforcing mechanism 2 is placed into the receiving hole at the matrix center position of the four support frames 1 (the reinforcing mechanism 2 at this position is slightly different from the reinforcing mechanisms 2 at other positions in structure. Specifically, during the placement process, the mounting sleeve 211 is first inserted into the receiving hole. The top end of the mounting sleeve 211 is provided with a plurality of locking grooves 2115 along the circumferential direction, and each linkage plate 14 is fixedly provided with a plurality of locking blocks 142 on one side close to each other. Therefore, during the placement process of the mounting sleeve 211 at this position, the locking blocks 142 need to be accurately inserted into the corresponding locking grooves 2115. As mentioned above, the upper and lower support frames 1 have completed the locking and limiting, so the linkage plates 14 arranged thereon will not shake. When the locking blocks 142 are inserted into the locking grooves 2115, it means that the mounting sleeve 211 at this position will not rotate in the circumferential direction. After the above steps are completed, the mounting rod 221 is screwed into the inside of the mounting sleeve 211, so that the mounting sleeve 211, the mounting rod 221 and the rock-soil layer are stably engaged).

[0057] The existing reinforcement technology mostly still stays in single-point and independent reinforcement mode, and each anchor rod lacks effective mechanical connection, and cannot form a whole and cooperative stress system. When uneven deformation or local stress concentration occurs in the slope body, single anchor rod is prone to be damaged one by one, and finally leads to failure of the whole reinforcement system. Based on the above problems, after the locking work on the slope surface is completed, the adjusting disc 2251 is first driven to rotate by an external electric tool. In this process, the adjusting disc 2251 synchronously drives the circular rod 2253 and the connecting block 2252 to rotate and be clamped into the arc-shaped groove 141 of the linkage plate 14. Then, the threaded holes 2254 on the adjusting disc 2251 are screwed in turn, so as to realize the linkage and locking work of the four linkage plates 14, and further ensure that the four support frames 1 are stressed and linked as a whole (the end of the corresponding arc-shaped groove 141 on the linkage plate 14 is provided with a matching hole, after the circular rod 2253 is rotated into the corresponding arc-shaped groove 141, the threaded rod gradually penetrates the circular rod 2253 and enters the matching hole when being screwed into the threaded hole 2254, thereby realizing the linkage and locking work of the linkage plates 14), and after the linkage work of the four support frames 1 is completed, the installation and locking work of the tensioning assembly 21 and the auxiliary assembly 22 on both sides of the support frame 1 is completed in turn.

[0058] It should be noted that, in order to fundamentally solve the harm of groundwater to the stability of the slope 100, the blind ditch is opened to actively drain the excess pore water in the slope 100. Specifically, a ditch with a slope needs to be excavated in the slope 100, and a sand cushion is laid at the bottom of the ditch. Then, the geotextile is laid on the wall of the ditch, and the water permeable pipe with holes is put into the pipe and completely wrapped with clean graded gravel. Finally, the geotextile is folded and overlapped to form a "clean drainage core" isolated from the external soil, and is backfilled and tamped in layers. Through an underground drainage channel composed of geotextile and gravel, which can permeate water but effectively prevent silt from blocking, the harmful groundwater inside is orderly discharged, thereby reducing the pore water pressure and improving the strength of the rock-soil body, and ensuring the long-term stability and safety of the slope 100 from the source.

[0059] It is worth emphasizing that the annular hoop linkage type rock-soil slope protection and reinforcement structure with anti-seepage blind ditch mainly has the following advantages:

[0060] Advantage one, during construction, only need to drill a hole on the slope 100, then put the installation sleeve 211 into the hole, and then rotate the installation rod 221 through the electric tool. During the rotation process, the conical block 222 at the bottom of the installation rod 221 will push the expansion of the tension block 212, so that it is tightly engaged with the hole wall. At the same time, the self-tapping head 223 is screwed into the rock-soil layer. Once this process is completed, the anchoring force is immediately generated without waiting for any material to coagulate or maintain. Subsequently, by adjusting the top block 224 on the installation rod 221 and the abutting block 2133 of the support frame 1, the support frame 1 and the anchoring point can be locked instantly. This mechanical anchoring method, which takes effect immediately after installation, completely eliminates the long waiting time for concrete maintenance in traditional processes, which lasts for several days or even longer. It changes the slope 100 reinforcement from a long "wet work" process to a quick "dry work" process, greatly shortens the construction period, improves engineering efficiency, and is especially suitable for emergency rescue projects that require quick support to ensure safety or projects with strict time requirements.

[0061] Advantage two, the structure is connected by mechanical methods such as clamping plates, linkage grooves 13, and threads, rather than being poured once. When periodic inspection of the slope 100 is required, the status of each connecting piece can be directly observed. Once it is found that a certain anchoring unit (such as the installation rod 221) has performance degradation or failure due to long-term corrosion or ground creep, the corresponding locking mechanism (such as the installation rod 221) can be loosened to remove and replace the failed unit without damaging the entire slope protection structure. This modular and replaceable design changes the traditional "one-time" concealed engineering into an "maintainable and replaceable" open system, which completely solves the problem of undetectable and unrepairable traditional anchor rod failure, making long-term and dynamic maintenance of the slope 100 protection possible. This not only greatly extends the service life of the entire reinforcement system and reduces the maintenance cost throughout the life cycle, but also fundamentally improves the long-term safety and reliability of the slope 100.

[0062] Advantage three, while the operator is screwing in the installation rod 221 to realize its anchoring with the rock-soil layer, the adjusting top block 224 on the installation rod 221 will move, the outer wall of the adjusting top block 224 will extrude the abutting block 2133 in the supporting frame 1 bearing seat 2132, and the abutting block 2133 will be clamped into the linkage groove 13 of the installation sleeve 211, and this series of actions occur synchronously, which means that the operator only needs to perform a single action of "screwing in the installation rod 221" to simultaneously complete the three key steps of "installing the installation sleeve 211 to engage with the rock-soil", "locking the installation rod 221 with the installation sleeve 211", and "fixing the installation sleeve 211 with the supporting frame 1". This single operation driven multiple linkage locking greatly simplifies the installation process, reduces the operation complexity and the requirement for worker skills, and more importantly, it tightly connects the anchoring points, the supporting frame 1 and other key components into a stable whole through mechanical linkage, avoiding the connection loosening or stress unevenness caused by step-by-step installation, thereby effectively improving the stability of the installation and the integrity of the structure, ensuring that the slope protection system can resist external forces as a whole.

[0063] Advantage four, after completing the independent anchoring of the four supporting frames 1 on the slope surface, the structure connects them into a whole frame through a key "hooping" step. The operator rotates the adjusting disc 2251, drives the circular rod 2253 thereon to be clamped into the arc-shaped groove 141 of the linkage plate 14 of the four supporting frames 1, and then completely locks the circular rod 2253 with the linkage plate 14 through the threaded rod. In this way, the originally independent four supporting frames 1 are tightly hooped together to form a matrix whole frame. When stress occurs in a part of the slope body, the force will be quickly transmitted and dispersed to all anchoring points through the frame. It integrates the dispersed anchoring points into a mechanically cooperative system, which can effectively resist the uneven deformation and local stress concentration of the slope body, avoiding the risk that a single anchor rod is "knocked out one by one" under a huge load. Therefore, the bearing capacity and safety redundancy of the whole reinforcement system are greatly improved, ensuring the long-term stability and safety of the slope protection under complex geological conditions.

[0064] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit it; although the foregoing embodiments of the present application have been described in detail, those skilled in the art should understand that they can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present application.
