Description

Technical Field

[0001] The utility model relates to the field of support structures, in particular to a cable anchor lattice slope support structure. Background Art

[0002] Slope support refers to the retaining, reinforcement and protection measures taken for slopes to ensure the safety of slopes and their environments. The main purpose of slope support is to prevent geological disasters such as landslides and collapses from occurring under the action of natural environments or human factors, so as to ensure the safety of people's lives and property. There are various ways of slope support. Among them, the cable anchor lattice slope support structure is a slope support technology that combines prestressed cable anchors and lattice beam structures. It uses the tensile force of prestressed cable anchors to pull the potential sliding mass of the slope towards the stable stratum. At the same time, the lattice beam is in close contact with the slope surface, dispersing the pressure on the slope and transmitting these forces to the prestressed cable anchors. This composite structure can effectively reinforce and stabilize the slope, preventing the occurrence of geological disasters such as landslides and collapses.

[0003] Most of the existing lattice beams are directly attached to the slope for protection. Since the connection between the lattice beam and the slope is not particularly tight, it is easy to shake, which makes the slope prone to geological disasters such as landslides and collapses. This not only destroys the stability of the slope itself, but also may pose a threat to surrounding buildings, roads, personnel, etc. In addition, problems such as work stoppage and delay caused by the instability of the slope support structure will also bring additional economic losses to the project and reduce the construction efficiency.

[0004] Therefore, in view of the problem that most of the existing lattice beams are directly attached to the slope for protection, and since the connection between the lattice beam and the slope is not particularly tight and is easy to shake, which not only poses a threat to surrounding buildings, roads, personnel, etc., but also leads to situations such as construction suspension or delay, a cable anchor lattice slope support structure can be designed to install a fixing structure that fits the slope on the lattice beam to enhance the stability of slope support. Summary of the Utility Model

[0005] In order to overcome the problem that most of the existing lattice beams are directly attached to the slope for protection, and since the connection between the lattice beam and the slope is not particularly tight and is easy to shake, which not only poses a threat to surrounding buildings, roads, personnel, etc., but also leads to situations such as construction suspension or delay.

[0006] The technical solution of the utility model is as follows: An anchor cable lattice slope support structure, which includes longitudinal beams, transverse beams, fixing nails, grid placement baffles, fixing components and installation components; there are multiple groups of longitudinal beams and transverse beams, and multiple groups of longitudinal beams and transverse beams are arranged vertically and horizontally in a crosswise manner. Multiple groups of fixing nails for preliminarily fixing the longitudinal beams and transverse beams to the slope are horizontally installed at the lower ends of the longitudinal beams and transverse beams. Fixing components for further fixing by penetrating deep into the slope are vertically provided at the cross-connection points of the longitudinal beams and transverse beams. Multiple groups of installation components for tightly fixing the longitudinal beams and transverse beams to the slope are arranged along the upper sides of the longitudinal beams and transverse beams. A grid placement baffle for placing heavy objects to assist in fixing is provided above the installation components. The fixing component includes a square sealing cover, a square sealing ring, a square fixing block, an anchor cable grouting pipe, a steel strand, an inclined fixing thorn, a guiding cap and a slurry overflow port. An anchor cable grouting pipe is penetrated through the middle of the inner side of the square fixing block. Four groups of steel strands are penetrated around the periphery of the square fixing block through which the anchor cable grouting pipe is penetrated. A guiding cap is installed at the lower ends of the anchor cable grouting pipe and the four groups of steel strands. The installation component includes a convex fixing frame, fixing bolts, first nuts, rectangular clamping blocks, rectangular clamping grooves, second fixing holes, installation bolts and second nuts. Fixing bolts are penetrated through both ends of the convex fixing frame, and first nuts are sleeved outside the fixing bolts.

[0007] Preferably, first, the fixing components are successively penetrated deep into the slope, driving the longitudinal beams and transverse beams to continuously fit and approach the slope. The fixing nails drive the longitudinal beams and transverse beams to be further fixed to the slope. Then, the installation components further fix the longitudinal beams and transverse beams to the slope. Then, the grid placement baffle and the installation components are assembled. Finally, heavy objects are placed on the grid placement baffle, and the gravity of the heavy objects is used to assist in fixing the slope downward. Through multiple fixing structures, the longitudinal beams and transverse beams are in close contact with the slope surface, which can disperse the soil pressure or rock pressure on the slope and transmit these forces to the anchor cables. At the same time, a stable slope is crucial for ensuring the safety of transportation, residents' lives and the ecological environment. The strengthened anchor cable lattice slope support structure can reduce safety accidents caused by slope instability and improve the overall safety and construction efficiency of the area.

Heavy objects can be placed on the grid placement baffle, and the gravity of the heavy objects is used to assist in fixing the slope downward, improving the stability of the support structure.

[0009] As a preference, a square sealing cover is provided above the square fixing block, and a square sealing ring is installed at the lower edge of the square sealing cover. By applying effective prestress to the guiding cap, the guiding cap drives the anchor cable grouting pipe to continuously penetrate deep into the slope. At the same time, the steel strand drives the inclined fixing thorn to continuously penetrate deep into the slope, increasing the compressive strength of the anchor cable.

[0010] Preferably, the square sealing ring drives the square sealing cover to fit and connect with the inner wall of the square fixing block. After the anchor cable grouting pipe is filled, pick up the square sealing cover, and the square sealing ring drives the square sealing cover to fit and connect with the inner wall of the square fixing block.

[0011] Preferably, multiple groups of obliquely fixed spines are linearly installed on the outside of the steel strand. An overflow port for the outflow of cement mortar is opened below the guide cap. The cement mortar is poured into the anchor cable grouting pipe and then flows out through the overflow port. After the cement mortar dries, it is more firmly connected to the slope. The anchor cable grouting pipe and the steel strand are fixed in the square fixing block, effectively making the anchor cable more firm.

[0012] Preferably, a rectangular clamping block is installed at the upper end of the convex fixing frame. A rectangular clamping groove for clamping the grid placement baffle is opened in the middle of the rectangular clamping block. After the longitudinal beam and the transverse beam are further fixed, pick up the convex fixing frame and clamp it with the longitudinal beam and the transverse beam. Then pass the fixing bolt through the convex fixing frame and fixedly connect it to the slope, and then tighten and fix it with the first nut.

[0013] Preferably, second fixing holes are symmetrically opened on both sides of the rectangular clamping block. An installation bolt passes through the middle of the second fixing hole opened in the rectangular clamping block. Second nuts are sleeved on the outer sides of both ends of the installation bolt. Pick up the grid placement baffle, positionally connect it with the rectangular clamping block along the rectangular clamping groove. Finally, pick up the installation bolt, pass it through the first fixing hole on the grid placement baffle and the second fixing hole on the rectangular clamping block, and then tighten and fix it with the second nut.

[0015] 1. First, the fixing components are successively inserted into the slope, driving the longitudinal beam and the transverse beam to continuously fit and approach the slope. The fixing nails drive the longitudinal beam and the transverse beam to be further fixed to the slope. Then the installation components further fix the longitudinal beam and the transverse beam to the slope. Then the grid placement baffle and the installation components are assembled. Finally, a heavy object is placed on the grid placement baffle, and the gravity of the heavy object is used to assist in fixing the slope downward. Through multiple fixing structures, the longitudinal beam and the transverse beam are in close contact with the slope surface, which can disperse the soil pressure or rock pressure on the slope and transmit these forces to the anchor cable. At the same time, a stable slope is crucial for ensuring the safety of transportation, residents' lives, and the ecological environment. The strengthened fixed anchor cable lattice slope support structure can reduce safety accidents caused by slope instability and improve the overall safety and construction efficiency of the area;

[0016] 2. By applying effective prestress to the guiding cap, the guiding cap drives the anchor cable grouting pipe to continuously penetrate into the slope. At the same time, the steel strand drives the diagonal fixing spines to continuously penetrate into the slope, increasing the compressive strength of the anchor cable. Then, cement mortar is poured into the anchor cable grouting pipe and flows out through the slurry overflow port. After the cement mortar dries, it is more firmly connected to the slope. When the anchor cable grouting pipe is filled, pick up the square sealing cover, and the square sealing ring drives the square sealing cover to fit and connect along the square fixing block and its inner wall.

[0027] Please refer to Figure 3 As shown in the figure, in this embodiment, a first fixing hole 401 for assembling with the installation component is opened on the grid placement baffle 4. Heavy objects can be placed on the grid placement baffle 4, and the slope is assisted in fixing downward by the gravity of the heavy objects, so as to improve the stability of the support structure.

[0028] Please refer to Figure 4 - Figure 5 In this embodiment, a square sealing cover 501 is provided above the square fixing block 503. A square sealing ring 502 is installed at the lower edge of the square sealing cover 501. By applying effective prestress to the guide cap 507, the guide cap 507 drives the cable anchor grouting pipe 504 to continuously penetrate into the slope. At the same time, the steel strand 505 drives the diagonal fixing thorn 506 to continuously penetrate into the slope, increasing the compressive strength of the cable anchor. The square sealing ring 502 drives the square sealing cover 501 to fit and connect with the inner wall of the square fixing block 503. When the cable anchor grouting pipe 504 is filled, pick up the square sealing cover 501, and the square sealing ring 502 drives the square sealing cover 501 to fit and connect with the inner wall of the square fixing block 503.

[0029] Please refer to Figure 6 In this embodiment, a rectangular clamping block 604 is installed at the upper end of the convex fixing frame 601. A rectangular clamping groove 605 for clamping the grid placement baffle 4 is provided in the middle of the rectangular clamping block 604. After the longitudinal beam 1 and the transverse beam 2 are further fixed, pick up the convex fixing frame 601 and clamp it with the longitudinal beam 1 and the transverse beam 2. Then pass the fixing bolt 602 through the convex fixing frame 601 and fixedly connect it to the slope, and then tighten and fix it with the first nut 603. Second fixing holes 606 are symmetrically provided on both sides of the rectangular clamping block 604. An installation bolt 607 passes through the middle of the second fixing holes 606 provided in the rectangular clamping block 604. Second nuts 608 are sleeved on the outer parts of both ends of the installation bolt 607. Pick up the grid placement baffle 4 and positionally connect it to the rectangular clamping block 604 along the rectangular clamping groove 605. Finally, pick up the installation bolt 607, pass it through the first fixing hole 401 on the grid placement baffle 4 and the second fixing hole 606 on the rectangular clamping block 604, and then tighten and fix it with the second nut 608.

[0030] When working, an effective prestress is applied to the guide cap 507. The guide cap 507 drives the anchor cable grouting pipe 504 to continuously penetrate into the slope. At the same time, the steel strand 505 drives the diagonal fixing thorn 506 to continuously penetrate into the slope. Then, cement mortar is poured into the anchor cable grouting pipe 504 and flows out through the slurry overflow port 508. After the cement mortar dries, it is more firmly connected to the slope. When the anchor cable grouting pipe 504 is filled, pick up the square sealing cover 501. The square sealing ring 502 drives the square sealing cover 501 to fit and connect along the inner wall of the square fixing block 503. The anchor cable grouting pipe 504 and the steel strand 505 are fixed in the square fixing block 503, effectively making the anchor cable more firm. During this process, the fixing nails 3 drive the longitudinal beam 1 and the transverse beam 2 to be further fixed to the slope;

[0031] After the longitudinal beam 1 and the transverse beam 2 are further fixed, pick up the convex fixing frame 601 and engage it with the longitudinal beam 1 and the transverse beam 2. Then, pass the fixing bolt 602 through the convex fixing frame 601 and fixedly connect it to the slope, and then tighten and fix it with the first nut 603. Then, pick up the grid placement baffle 4 and positionally connect it along the rectangular clamping groove 605 and the rectangular clamping block 604. Immediately afterwards, pick up the installation bolt 607, pass it through the first fixing hole 401 on the grid placement baffle 4 and the second fixing hole 606 on the rectangular clamping block 604, and then tighten and fix it with the second nut 608. Finally, place the heavy object on the grid placement baffle 4, and use the gravity of the heavy object to assist in fixing the slope support structure downward.

[0032] Through the above steps, first, the fixing components are successively penetrated into the slope, driving the longitudinal beam 1 and the transverse beam 2 to continuously fit and approach the slope. The fixing nails 3 drive the longitudinal beam 1 and the transverse beam 2 to be further fixed to the slope. Then, the installation components further fix the longitudinal beam 1 and the transverse beam 2 to the slope. Then, the grid placement baffle 4 and the installation components are assembled. Finally, the heavy object is placed on the grid placement baffle 4, and the gravity of the heavy object is used to assist in fixing the slope downward. Through multiple fixing structures, the longitudinal beam 1 and the transverse beam 2 are in close contact with the slope surface, which can disperse the soil pressure or rock pressure on the slope and transmit these forces to the anchor cable. At the same time, a stable slope is crucial for ensuring the safety of transportation, residents' lives, and the ecological environment. The strengthened fixed anchor cable lattice slope support structure can reduce safety accidents caused by slope instability, improve the overall safety of the area and the construction efficiency, so as to solve the problem that most of the existing lattice beams are directly attached to the slope for protection. Since the connection between the lattice beam and the slope is not particularly tight, it is easy to shake, which not only poses a threat to surrounding buildings, roads, personnel, etc., but also leads to construction suspension or delay, etc.
