Description

Technical Field

[0001] The utility model relates to the technical field of slopes, in particular to a slope reinforcement structure. Background Art

[0002] When reinforcing a slope, a common reinforcement method is: constructing vertical anti-slip piles at the bottom of the slope, with the bottom of the anti-slip piles inserted below the ground, and the top of the anti-slip piles extending from the ground. The sides of the anti-slip piles are against the vertical sides of the slope, and at the same time, retaining walls are constructed on the vertical sides of the slope. The retaining walls are connected to the anti-slip piles as a whole, so that the anti-slip piles and the retaining wall work together to reinforce the bottom of the slope and prevent the slope from sliding.

[0003] The construction method of the above anti-slip piles is: first dig a deep pit on the ground, then use a crane to lift the cylindrical steel cage to a vertical state, and gradually lower the steel cage into the deep pit, and then pour concrete mortar into the steel cage to complete the construction of the anti-slip piles.

[0004] However, in some canyon areas, the terrain is relatively steep and the construction site is relatively small, so large cranes cannot enter the relatively small construction site, or even if large cranes can enter the construction site, the lifting height will be limited by the surrounding environment, so in this case only small cranes can be used to lift the steel cage. However, the lifting height of a small crane cannot reach the lifting height of a large crane, and the length of the steel cage is relatively long. Using a small crane, it is impossible to fully lift the steel cage into a vertical state, which brings difficulties to the construction and lowering of the steel cage. Utility Model Content

[0005] The utility model aims to provide a slope reinforcement structure so as to facilitate the vertical lowering of a steel cage into a deep pit.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a slope reinforcement structure, including an anti-slip pile, the anti-slip pile includes a steel cage and concrete cast on the steel cage, the steel cage is divided into an upper and a lower section, the upper and lower sections of the steel cage are an upper steel cage and a lower steel cage respectively, the top of the lower steel cage is fixedly connected with a first fixing part, the bottom of the upper steel cage is fixedly connected with a second fixing part, the upper steel cage is located above the lower steel cage, the first fixing part is provided with a plurality of first clamping parts, and the second fixing part is provided with a plurality of second clamping parts cooperating with the first clamping parts.

[0007] The principle and advantage of this scheme are: this scheme divides the entire steel cage into two sections, namely the upper steel cage and the lower steel cage, and completes the lifting construction of the steel cage by lifting the lower steel cage and the upper steel cage respectively. During lifting, first lift the lower steel cage and lower the lower steel cage vertically into the deep pit, and the first fixing part of the lower steel cage is located at the top of the lower steel cage. Then lift the upper steel cage and place it on the lower steel cage. At this time, the second fixing part of the upper steel cage is located at the bottom of the upper steel cage, and the first fixing part and the second fixing part fit together. The first clamping part and the second clamping part cooperate with each other, so that the first fixing part and the second fixing part are clamped and fixed, and the installation and positioning of the upper steel cage and the lower steel cage are realized. The upper steel cage and the lower steel cage are not easy to shift laterally, which is convenient for the subsequent fixing of the first fixing part and the second fixing part. After the first fixing part and the second fixing part are fixed, concrete mortar is poured to complete the construction of the anti-slip pile.

[0008] Therefore, through this solution, the entire steel cage is divided into two sections. The lower steel cage and the upper steel cage are lifted separately and then fixed by the first clamping part and the second clamping part, thereby realizing the installation of the entire steel cage. Compared with the prior art of lifting the entire steel cage that is not divided into two sections at one time, the lifting height is greatly reduced, which is convenient for the lifting construction of the steel cage. The lifting of the steel cage is less affected by the site space and the lifting height of the lifting equipment, which makes it easy to lower the steel cage into a deep pit and facilitate the construction of anti-slip piles.

[0009] Preferably, as an improvement, the first engaging portion is an insert rod, and the second engaging portion is an insert hole; or, the first engaging portion is an insert hole, and the second engaging portion is an insert rod;

[0010] The plug rod and the plug hole are both vertical, and the plug rod is inserted into the plug hole.

[0011] Therefore, by inserting the insertion rod into the insertion hole, the positioning and installation of the first fixing part and the second fixing part are achieved, and the upper steel cage and the lower steel cage can be positioned and connected together. With this structure, when the upper steel cage is lowered into the lower steel cage, the insertion rod and the insertion hole are relative to each other, so that the insertion rod can be inserted into the insertion hole to achieve the positioning of the upper steel cage and the lower steel cage. The structure is simple and the operation is convenient.

[0012] Preferably, as an improvement, the first fixing portion and the second fixing portion are both annular.

[0013] Preferably, as an improvement, the portion where the first fixing portion and the second fixing portion are connected is fixed by welding. The first fixing portion and the second fixing portion are fixed by welding, and the first fixing portion and the second fixing portion are firmly fixed.

[0014] Preferably, as an improvement, the insertion rod is provided with threads, and after the insertion rod is inserted into the insertion hole, a nut is threadedly connected to the screw rod.

[0015] After the first fixing part and the second fixing part are fitted together, the nut is threadedly connected to the insertion rod, so that the first fixing part and the second fixing part are connected together, and the first fixing part and the second fixing part can be initially fixed vertically. In this way, when the first fixing part and the second fixing part are subsequently welded, the upper steel cage is lifted upward, and the upper steel cage drives the lower steel cage to move upward and away from the bottom of the deep pit through the connection between the nut and the insertion rod. The lower steel cage is suspended in the deep pit, and the upper steel cage and the lower steel cage will not separate in the vertical direction. At this time, the entire steel cage can be rotated to change the orientation of the entire steel cage. In this way, when the first fixing part and the second fixing part are circumferentially welded, the entire steel cage is rotated, so that the fitting parts of the first fixing part and the second fixing part can be welded while the steel cage is rotated to change its position, thereby realizing welding all around the first fixing part and the second fixing part, and the first fixing part and the second fixing part are fully welded, thereby improving the firmness and stability of the connection between the first fixing part and the second fixing part.

[0016] Preferably, as an improvement, a card slot is provided on the side wall of the insertion rod, a transverse sliding hole is provided on the inner wall of the insertion hole, a card block slides transversely in the sliding hole, one end of the card block extends out of the sliding hole, and a compression spring is connected between the other end of the card block and the inner wall of the sliding hole; after the insertion rod is inserted into the insertion hole, the card block is stuck in the card slot under the elastic force of the compression spring.

[0017] Thus, when the rod is inserted into the insertion hole, the rod pushes the block back into the sliding hole. After the rod is inserted, the block and the slot are opposite, and the block is automatically inserted into the slot under the elastic force of the compression spring, thereby locking the rod and preventing the rod from being withdrawn from the insertion hole, thus achieving automatic vertical fixation of the first fixing part and the second fixing part. In this way, when the first fixing part and the second fixing part are subsequently welded, when the entire steel cage is lifted upward and rotated for transposition, it is no longer necessary to use a nut threaded connection on each rod to vertically fix the first fixing part and the second fixing part, which makes the operation simpler and more convenient, saving construction time.

[0018] Preferably, as an improvement, one end of the insertion hole is the entry end of the insertion rod, and the side of the block facing the entry end is an inclined surface. Thus, the setting of the inclined surface ensures that when the insertion rod is inserted into the insertion hole, the end of the insertion rod will not be stuck with the block, and the insertion rod can push the block to move toward the sliding hole to make way for the insertion rod to be inserted into the insertion hole.

[0019] Preferably, as an improvement, the first engaging portion or the second engaging portion comprises a body and a cover, the body and the cover are fixedly connected, the sliding hole is located on a side of the body, and the cover covers the sliding hole to seal the sliding hole.

[0020] Thus, the compression spring and the block are placed in the sliding hole of the body, and then the cover is placed on the body, the cover seals the sliding hole, so that the compression spring and the block are located in the sliding hole and will not fall out from the side of the sliding hole. After the cover is placed on the body, the cover and the body are fixed, and the cover and the body are not easy to separate. The structure of this solution makes it easy to place the block and the compression spring in the sliding hole of the body.

[0021] Preferably, as an improvement, a limit groove is provided on the card block, and a limit block is fixedly connected to the cover or the body, and the limit block is located in the limit groove. The setting of the limit groove is used to limit the sliding of the card block to prevent the card block from sliding out of the sliding hole under the action of the compression spring.

[0022] Preferably, as an improvement, the end of the insertion rod is provided with a chamfer. The chamfer can guide the insertion of the insertion rod into the insertion hole, making it easier for the insertion rod to be inserted into the insertion hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Example 1

[0033] Basically as attached Figure 1-Figure 4 As shown: the slope reinforcement structure includes a plurality of vertically arranged anti-slip piles 3, wherein the plurality of anti-slip piles 3 are arranged in a row, and the bottom of the anti-slip piles 3 are inserted below the ground 2, and the insertion depth of the anti-slip piles 3 is half of the length of the anti-slip piles 3 themselves. In this embodiment, the length of the entire anti-slip pile 3 is 10m. A crossbeam 4 is fixedly cast on the top of the anti-slip pile 3, and a retaining wall 5 of reinforced concrete structure is cast between the bottom of the crossbeam 4 and the ground 2, and the retaining wall 5 and the anti-slip piles 3 are connected as a whole. Thus, Figure 1 The anti-slide piles 3 and the retaining wall 5 are located on the left side of the slope 1 and are against the vertical side of the slope 1, thereby reinforcing the slope 1, preventing the slope 1 from sliding, and improving the stability of the slope 1.

[0034] The improved structure of this embodiment lies in the structure of the anti-slip pile 3. Specifically, the anti-slip pile 3 includes a steel cage and concrete poured on the steel cage. The steel cage in this embodiment is divided into an upper section and a lower section. Figure 3 and Figure 4 As shown, the upper and lower sections of the steel cage are respectively an upper steel cage 22 and a lower steel cage 7. Both the upper steel cage 22 and the lower steel cage 7 are cylindrically welded with steel bars. The lengths of the upper steel cage 22 and the lower steel cage 7 are equal, both 5 meters. The top of the lower steel cage 7 is welded and fixedly connected with a first fixing portion 6. The first fixing portion 6 in this embodiment is annular, and of course it can also be disc-shaped in other embodiments.

[0035] The bottom of the upper steel cage 22 is welded and fixedly connected with a second fixing part 9, and the second fixing part 9 has the same shape as the first fixing part 6. The first fixing part 6 is provided with a plurality of first clamping parts, and the second fixing part 9 is provided with a plurality of second clamping parts that cooperate with the first clamping parts. In this embodiment, the first clamping part is a vertical plug hole 8, the two ends of the plug hole 8 are connected, and the plug holes 8 are evenly distributed around the central circumference of the first fixing part 6, and the second clamping part is a vertical plug rod 10, the top of the plug rod 10 is welded to the bottom of the second fixing part 9, and a plurality of plug rods 10 are evenly distributed around the central circumference of the second clamping part. The plug rod 10 can be inserted into the plug hole 8. Of course, in other embodiments, the first clamping part can also be a vertical plug rod 10, the bottom end of the plug rod 10 is welded to the top of the first fixing part 6, and the second clamping part is a plug hole 8 located on the second fixing part 9, and the plug rod 10 can be inserted into the corresponding plug hole 8.

[0036] The insert rod 10 is provided with threads. After the insert rod 10 is inserted into the insertion hole 8, a nut (not shown in the figure) is threadedly connected on the screw rod through the pores 11 of the lower reinforcement cage 7.

[0037] Since the improvement of this embodiment lies in the structure of the anti-sliding piles 3, the specific implementation process of the anti-sliding piles 3 is described in detail, and other structures (such as the retaining wall 5) are not described because they belong to the prior art.

[0038] The specific implementation process of the anti-slip pile 3 is as follows: first, a deep hole is drilled on the ground 2, and the depth of the deep hole is the depth of the lower steel cage 7. Then, the upper steel cage 22 and the lower steel cage 7 are transported to the construction site, and the lower steel cage 7 is hoisted by a crane through a steel wire rope. Since the length of the lower steel cage 7 is 5m, the hoisting height of the lower steel cage 7 can be 5m (no need to be 10m), and the lower steel cage 7 is vertically lowered into the deep pit, and the first fixing portion 6 of the lower steel cage 7 is located at the top of the lower steel cage 7.

[0039] Then untie the steel wire rope on the lower steel cage 7, and then use the steel rope to lift the upper steel cage 22. Since the length of the upper steel cage 22 is 5m, the lifting height of the upper steel cage 22 can be 5m (no need for 10m). After the upper steel cage 22 is lifted, place the upper steel cage 22 on the lower steel cage 7. At this time, the second fixing portion 9 of the upper steel cage 22 is located at the bottom of the upper steel cage 22, the first fixing portion 6 and the second fixing portion 9 are fitted, and the insertion rod 10 is inserted into the corresponding insertion hole 8, so that the first fixing portion 6 and the second fixing portion 9 are engaged and fixed, thereby realizing the installation and positioning of the upper steel cage 22 and the lower steel cage 7, and the upper steel cage 22 and the lower steel cage 7 are not easy to shift laterally.

[0040] After the insertion rod 10 is inserted into the insertion hole 8, the bottom end of the insertion rod 10 extends out from the insertion hole 8, and then the nut is threaded onto the insertion rod 10 through the top hole 11 of the lower reinforcement cage 7, and the nut is tightened so that the nut is against the bottom of the first fixing part 6, so that the first fixing part 6 and the second fixing part 9 are connected together, so that the first fixing part 6 and the second fixing part 9 can be initially fixed vertically.

[0041] Then the upper steel cage 22 is lifted upwards, and the upper steel cage 22 drives the lower steel cage 7 to move upwards and away from the bottom of the deep pit through the connection of the nut and the plug rod 10. Since the first fixing part 6 and the second fixing part 9 are connected together by the plug rod 10 and the nut, the upper steel cage 22 and the lower steel cage 7 will not separate in the vertical direction. The bottom of the lower steel cage 7 is suspended in the deep hole. At this time, the entire steel cage is manually moved, and the entire steel cage can be slowly rotated, thereby changing the orientation of the entire steel cage. In this way, when welding the first fixing part 6 and the second fixing part 9, the entire steel cage can be rotated to change the position while welding the first fixing part 6 and the second fixing part 9, so as to change the welding position of the first fixing part 6 and the second fixing part 9, so as to realize the welding of the first fixing part 6 and the second fixing part 9 around the periphery, and avoid the first fixing part 6 and the second fixing part 9 close to the side of the slope 1. It is difficult to weld and the first fixing part 6 and the second fixing part 9 cannot be fully welded. Through this solution, the first fixing portion 6 and the second fixing portion 9 are fully welded, thereby improving the firmness and stability of the connection between the first fixing portion 6 and the second fixing portion 9.

[0042] After the first fixing part 6 and the second fixing part 9 are fixed, the entire steel cage is lowered, the steel wire rope is removed from the upper steel cage 22 , and then concrete mortar is poured, thereby completing the construction of the anti-slip pile 3 .

[0043] Example 2

[0044] Embodiment 1 uses nuts to fix the rod 10 and the first fixing portion 6. During operation, multiple nuts need to be tightened, which is relatively troublesome. This solution improves the structure of the first fixing portion 6 and also improves the structure of the rod 10, so as to facilitate the vertical fixation of the rod 10 and the first fixing portion 6. Figure 7 As shown, the side walls of the insertion rod 10 are each provided with a slot 20, the bottom of the slot 20 is a plane, and the top of the slot 20 is an inclined surface. Figure 6 As shown, a transverse sliding hole 17 is provided on the inner wall of the insertion hole 8, a block 15 is slid transversely in the sliding hole 17, one end of the block 15 extends out of the sliding hole 17, and a compression spring 16 is connected between the other end of the block 15 and the inner wall of the sliding hole 17. The card slot 20 of the insertion rod 10 and the block 15 can be opposite, the top of the end of the block 15 is provided with an inclined surface, and the bottom of the insertion rod 10 is provided with a chamfer 21.

[0045] After the rod 10 is inserted into the socket 8 (the top of the socket 8 is the entry end), the bottom of the rod 10 abuts against the inclined surface of the right end of the block 15, thereby pushing the block 15 to slide into the sliding hole 17. The block 15 squeezes the compression spring 16, and the block 15 retreats. The block 15 will not hinder the rod 10 from moving downward. After the rod 10 is inserted into the socket 8, the block 15 and the slot 20 are opposite. Figure 6 The middle card block 15 moves to the right under the elastic force of the compression spring 16, and the card block 15 is stuck in the card slot 20. The structure of the card block 15 stuck in the card slot 20 is as shown in FIG. Figure 5 As shown, the block 15 and the slot 20 are automatically engaged, and the rod 10 and the first fixing part 6 are automatically fixed vertically. In this way, there is no need to use nuts to fix a single rod 10, and the operation is simple and convenient. When the steel cage is subsequently lifted upward, the rod 10 moves upward, and the rod 10 drives the first fixing part 6 to move upward through the block 15, so that the bottom of the lower steel cage 7 is separated from the bottom of the deep pit.

[0046] In other embodiments, in order to facilitate the assembly of the block 15 and the spring, and to facilitate the manufacture and assembly of related structures, Figure 6 As shown, the first engaging portion includes a body 13 and a cover 12, and the upper side of the cover 12 is provided with the sliding hole 17 ( Figure 6 During assembly, the block 15 and the compression spring 16 are placed into the sliding hole 17 from the top of the sliding hole 17, and then the cover body 12 is covered on the top of the main body 13. After covering, the cover body 12 and the main body 13 are connected using fixing members 18, such as screws or bolts. The cover body 12 seals the top of the sliding hole 17, so that the block 15 and the compression spring 16 will not detach from the top opening of the sliding hole 17.

[0047] Through the above structure, the compression spring 16 and the clamping block 15 are installed in the first fixing part 6 .

[0048] In addition, in other embodiments, in order to prevent the block 15 from falling out from the right end of the sliding hole 17 under the elastic force of the compression spring 16, a limiting groove 14 is provided on the block 15, and a limiting block 19 is integrally formed on the bottom of the cover 12 or the inner wall of the sliding hole 17 of the body 13, and the limiting block 19 is located in the limiting groove 14. In this way, even if the insertion rod is not located in the insertion hole 8, the limiting block 19 abuts against the left end of the limiting groove 14, and the block 15 will not fall out from the right end of the sliding hole 17.

[0049] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
