Description
Technical Field
[0001] The present invention belongs to the technical field of building construction, and relates to a steel reinforcement cage installation device, specifically to an installation perfusion process for inclined cast-in-place piles. Background Art
[0002] Inclined piles have good compressive, anti-pulling and horizontal bearing capacities. At present, inclined piles are applied in many projects, such as the foundations of highway bridges, port terminals, transmission line towers and offshore drilling platforms. Through the application of inclined piles in existing projects, it is found that inclined piles can give full play to their axial compressive capacity and reduce the shear force and bending moment of the pile body caused by horizontal loads such as wind loads, seismic loads, flowing water and wave loads. Generally, under the action of the same load, inclined piles can bear a greater axial force than vertical piles, and the single-pile bearing capacity of inclined piles is larger than that of vertical piles. Using inclined piles can reduce the shear force and bending moment caused by lateral loads and give full play to the axial compressive capacity of the piles.
[0003] In the deep foundation pit support projects in China, although inclined piles have obvious advantages in resisting lateral loads, due to reasons such as construction machinery, technology and cost, vertical pile support forms have been widely used in row pile support structures, and inclined piles are rarely used. In recent years, Tianjin Urban Construction Base Group Co., Ltd. and Tianjin University have cooperated to develop a combined support technology for inclined foundation pit piles. This technology mainly uses hollow rectangular precast piles with a size of 500mm×375mm and an inclination angle of 15-20°. In 2019, Guangzhou Spartan Technology Company developed the YZY800X inclined pile static pile press, and the variable amplitude angle can reach ±20°, providing equipment guarantee for the construction of inclined precast piles. In 2020, the "Technical Specification for the Support Technology of Inclined Foundation Pit Piles without Support in Tianjin" DB / T29-286-2020 was issued, providing technical guarantee for the use of inclined piles in foundation pit support.
[0004] There are some problems in the application of precast inclined piles in foundation pit support. First, due to the small spacing between row piles, the soil squeezing effect increases, and continuous pile pressing is prone to deviation. Second, when the static pressure pile end enters the dense silt and fine sand layer, the pile pressing force increases, and it is difficult for the pile end to penetrate the hard soil layer, resulting in the pile length being shortened and unable to meet the requirements. The bored cast-in-place pile has no soil squeezing effect during pile formation, has strong adaptability to the formation, is not affected by hard interlayers, and has strong adjustability in pile length, pile diameter, and pile spacing. It has stronger applicability in both foundation pit support and foundations with large horizontal forces. In the 1970s, the Jiangsu Provincial Communications Engineering Brigade constructed a pile foundation for a certain bridge abutment with a diameter of 1.2 m, a pile length of 18.5 m, a slope of 7:1, and an inclination angle of 8.14°. The construction used a reverse circulation drill to form the hole. The steel reinforcement cage was installed into the hole using a guide frame composed of three seamless steel pipes and a semi-circular plate. Its functions were: first, to guide the steel reinforcement cage to be installed into the hole along the guide frame to prevent the steel reinforcement cage from touching the hole wall; second, the guide frame separated the steel reinforcement cage from the hole wall, acting as a protective layer. The specific method was to first place the guide frame tightly against the hole wall and into the hole, then lift the steel reinforcement cage and let it enter the hole along the guide frame, and then remove the guide frame after pouring the concrete. The Third Company of the 16th Bureau of China Railway summarized and formed a set of construction techniques for inclined bored cast-in-place piles. Among them, when installing the steel reinforcement cage, concrete support blocks were tied to the main reinforcement on the lower side of the steel reinforcement cage. The support blocks were used as guiding facilities for the steel reinforcement cage. The first row was tied 50 cm from the bottom end of the steel reinforcement cage, and 2 - 3 blocks were arranged along the circumference of the steel reinforcement cage skeleton for each row. One row was arranged every 3 - 4 m upward. The method of setting the guide frame is relatively cumbersome. In the method of setting the support blocks, the support blocks are prone to falling off due to friction with the hole wall, and the steel reinforcement cage may rotate when entering the hole, resulting in the support blocks being unable to slide linearly. The large number of sliders increases the weight of the steel reinforcement cage, resulting in an increase in the running resistance of the steel reinforcement cage in the hole. Summary of the Invention
[0005] In view of the above deficiencies in the prior art, the present invention provides an installation and pouring process for inclined cast-in-place piles to solve the problems of high soil squeezing effect, easy deviation of continuous pile pressing, and cumbersome installation methods in the prior art.
[0006] To solve the above technical problems, the present invention adopts the following technical solutions: An installation and pouring process for inclined cast-in-place piles is disclosed, including the following steps:
[0007] S1. It includes a tower rack assembly. There are upper and lower chutes on the tower rack assembly. An active sliding frame assembly is arranged in the upper chute. The tower rack assembly is in an inclined state. The active sliding frame assembly is aligned with the inclined hole. The tower rack assembly is arranged at one end of a mobile base. A first winch and a second winch are arranged at the other end of the mobile base. The first winch is connected to a guiding pulley assembly. The guiding pulley assembly is arranged on the lower chute. Release the first winch to make the guiding pulley assembly slide down. The guiding pulley assembly includes a guiding tube. There are keyways on the guiding tube. The keyways are closely attached to the active sliding frame assembly. Under the action of gravity, the guiding pulley assembly drives the active sliding frame assembly to move through the keyways until the guiding pulley assembly slides to the bottom of the lower chute, and the lower part of the active sliding frame assembly enters the inclined hole;
[0008] S2. The tower component includes two side columns, and the tower component further includes a top column. Two inclined columns are provided at the upper end of the top column, and a second fixed pulley is provided at the intersection of the two inclined columns. The steel reinforcement cage is hoisted by a second winch through the second fixed pulley. A plurality of connecting plates are evenly distributed at one end of the upper half parts of the two side columns close to the steel reinforcement cage. The connecting plates are connected to C-shaped sliding bars. The two side edges of the C-shaped sliding bars are respectively connected to the connecting plates. The steel reinforcement cage is hoisted and placed on two slide rails formed by the C-shaped sliding bars and the slide bars of the movable carriage assembly. The steel reinforcement cage slides into the inclined hole under its own weight. If the steel reinforcement cage needs to be extended, the top end of the steel reinforcement cage that has entered the hole is fixed at the hole opening, and the extended steel reinforcement cage is hoisted. As described above, the hoisted steel reinforcement cage is placed on two slide rails formed by the C-shaped sliding bars and the slide bars of the movable carriage assembly. After the bottom end of the steel reinforcement cage is connected to the top end of the steel reinforcement cage that has entered the hole, the extended steel reinforcement cage moves along the C-shaped sliding bars and the movable carriage assembly into the inclined hole. Finally, the top end of the steel reinforcement cage is fixed at the hole opening to complete the installation of the steel reinforcement cage;
[0009] S3. After the installation of the steel reinforcement cage is completed, a first fixed pulley is provided on the top column. The first winch is tightened and the guiding pulley assembly is lifted through the first fixed pulley, thereby driving the movable carriage assembly out of the inclined hole opening. A rotating shaft is provided on the inner surface of the lower end of the side column, and an arc-shaped connecting rod is provided on the rotating shaft. The arc-shaped connecting rod is connected to the supporting rod. When the lifting height of the slide shaft of the lower carriage of the movable carriage assembly exceeds the top of the supporting rod, the two supporting rods are rotated into the upper chute to clamp the movable carriage assembly, and the guiding pulley assembly is released. The slide shaft at the bottom of the movable carriage assembly is fixed to the supporting rod;
[0010] S4. The guiding pulley assembly continues to be lowered, and the conduit for pouring concrete is hoisted and spliced. The conduit is sleeved on the guiding pipe. The lower end of the guiding pipe is locked and connected to the end of the conduit by a movable clamp. The concrete flows into the conduit from the opening.
[0011] Further, upper chutes are provided on the inner surfaces of the upper ends of the two side columns close to the steel reinforcement cage. A movable carriage assembly is provided in the upper chutes. A guiding pulley assembly is provided on the side of the movable carriage assembly away from the steel reinforcement cage. The guiding pulley assembly is provided on the lower chute, and the lower chute is provided on the inner surface of the side column away from the steel reinforcement cage. The supporting rod can be rotated through the rotating shaft to clamp the supporting rod on the upper chute, which can limit the movement of the movable carriage assembly. The steel reinforcement cage fits on two slide rails formed by the C-shaped sliding bars and the slide bars of the movable carriage assembly and slides into the inclined hole under its own weight.
[0012] Further, a first steel wire rope is provided on the first fixed pulley. One end of the first steel wire rope is connected to the first winch, and the other end of the first steel wire rope is connected to the guiding pulley assembly. The first winch can control the lifting or lowering of the guiding pulley assembly, and the guiding pulley assembly is driven by controlling the first winch to pull the first steel wire rope.
[0013] Furthermore, a second steel wire rope is provided on the second fixed pulley. One end of the second steel wire rope is connected to the second winch, and the other end of the second steel wire rope is connected to the steel reinforcement cage. The second winch can control the steel reinforcement cage. First, lower the guiding pulley assembly and drive the movable carriage assembly to move downward into the hole, and then lift and place the steel reinforcement cage on the two slide rails formed by the C-shaped slide bar and the slide bar of the movable carriage assembly. The steel reinforcement cage moves along the C-shaped slide bar and the movable carriage assembly into the inclined hole.
[0014] Furthermore, the movable carriage assembly includes two slide bars. A connecting curved bar is provided between the two slide bars. Slide carriage slide shafts are also provided on the two slide bars. Slide carriage rolling bearings are provided at both ends of the slide carriage slide shafts, and the slide carriage rolling bearings are embedded in the upper chute. The movable carriage assembly can align with the already drilled inclined hole, and is driven by the guiding pulley assembly to enter the inclined hole along the inclined hole wall.
[0015] Furthermore, the guiding pulley assembly includes a guiding tube. A movable clamp is provided at the lower end of the guiding tube. An opening is provided inside the guiding tube at the upper end of the movable clamp. A pulley slide shaft is provided at the upper end of the opening. Pulley rolling bearings are provided at both ends of the pulley slide shaft, and the pulley rolling bearings are embedded in the lower chute. A key is provided on the guiding tube, and the key is provided on the side of the guiding tube close to the upper chute. The guiding pulley assembly can move on the lower chute, and by clamping the movable carriage assembly with the key, it can drive the movable carriage assembly to move into the inclined hole. When the steel reinforcement cage is lowered completely, lift the movable carriage assembly above the height of the supporting rod, rotate the supporting rod and clamp it in the upper chute to restrict the movement of the movable carriage assembly, so that the conduit can be fixed by the movable clamp at the bottom end of the guiding tube, and the guiding pulley assembly drives the conduit to move up and down along the inclined hole, thereby pouring concrete.
[0016] Furthermore, the length of the slide carriage slide shaft is the same as the length of the pulley slide shaft and the distance between the two side columns. The lengths of the slide carriage slide shaft and the pulley slide shaft should not be too large or too small, and need to be accurately clamped in the upper chute and the lower chute to realize the up and down movement of the movable carriage assembly and the guiding pulley assembly.
[0017] Furthermore, the height of the upper chute and the height of the lower chute are equal to the height of the side columns. The upper chute and the lower chute need to ensure that the guiding pulley assembly and the movable carriage assembly can move up and down on them, and at the same time ensure that the supporting rod can be clamped in the upper chute to restrict the movement of the movable carriage assembly.
[0018] Furthermore, the arc direction of the arc-shaped connecting rod faces the upper chute. When the arc-shaped connecting rod rotates, it rotates towards the upper chute direction, so as to clamp the supporting rod into the upper chute to restrict the downward movement of the movable carriage assembly.
[0019] Furthermore, the C-shaped slide bar has a C-shaped groove structure. The C-shaped slide bar wraps the slide rod of the movable carriage assembly, and the slide rod is arranged in the C-shaped groove of the C-shaped slide bar. The slide rod can slide up and down within the C-shaped slide bar, and the movable carriage assembly moves under the dual restrictions of the C-shaped slide bar and the upper chute.
[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] 1. The present invention can drive the movable carriage assembly through the guiding pulley assembly to smoothly install the steel reinforcement cage along the established track and direction. Only by pulling the steel reinforcement cage with the second hoist and sliding it into the inclined hole along the structure, the structure is simple and no complex operation is required.
[0022] 2. The present invention can realize the pouring of concrete. The lower end of the guiding tube of the guiding pulley assembly is connected to the conduit and fixed by the movable hoop, and the conduit is inserted deep into the inclined hole to play a role in positioning and cantilever fixing the conduit. The concrete flows into the conduit from the opening. During the pouring process, the guiding pulley assembly is continuously lifted and released, and the conduit slides up and down along the direction of the inclined hole accordingly, using the pouring and tamping of the concrete. The structure is simple and convenient, and an integrated structure for the installation of the steel reinforcement cage and the pouring of concrete can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of connecting plates 5 are evenly distributed at one end of the upper half of the two side columns 201 close to the steel reinforcement cage 10. The connecting plates 5 are connected to the C-shaped sliding bars 6. The two side edges of the C-shaped sliding bars 6 are respectively connected to the connecting plates 5. The steel reinforcement cage 10 is lifted and placed on two slide rails formed by the C-shaped sliding bars 6 and the slide bars 301 of the movable carriage assembly 3, and slides into the inclined hole 11 under its own weight. If the steel reinforcement cage 10 needs to be lengthened, the top end of the steel reinforcement cage 10 that has entered the hole is fixed at the hole opening. The lengthened steel reinforcement cage 10 is lifted. As described above, the lifted steel reinforcement cage 10 is placed on two slide rails formed by the C-shaped sliding bars 6 and the slide bars 301 of the movable carriage assembly 3. After the bottom end of the steel reinforcement cage 10 is connected to the top end of the steel reinforcement cage 10 that has entered the hole, the lengthened steel reinforcement cage 10 moves along the C-shaped sliding bars 6 and the movable carriage assembly 3 into the inclined hole 11. Finally, the top end of the steel reinforcement cage 10 is fixed at the hole opening to complete the installation of the steel reinforcement cage 10.
[0048] S3. After the installation of the steel reinforcement cage 10 is completed, a first fixed pulley 205 is provided on the top column 204. The first winch 207 is tightened to lift the guiding pulley assembly 4 through the first fixed pulley 205, thereby driving the movable carriage assembly 3 out of the inclined hole 11 opening. A rotating shaft 7 is provided on the inner surface at the lower end of the side column 201. An arc-shaped connecting rod 8 is provided on the rotating shaft 7. The arc-shaped connecting rod 8 is connected to the supporting rod 9. When the lifting height of the lower carriage slide shaft 303 of the movable carriage assembly 3 exceeds the top of the supporting rod 9, the two supporting rods 9 are rotated into the upper chute 202 to clamp the movable carriage assembly 3, and the guiding pulley assembly 4 is released. The slide shaft 303 at the bottom of the movable carriage assembly 3 is fixed to the supporting rod 9.
[0049] S4. The guiding pulley assembly 4 continues to be lowered. The conduit for pouring concrete is lifted and spliced. The conduit is sleeved on the guiding pipe 401. The lower end of the guiding pipe 401 is locked and connected to the end of the conduit through the movable clamp 402. The concrete flows into the conduit from the opening 403.
[0050] As Figure 1-2As shown in the figure, on the inner surface near the steel reinforcement cage 10 at the upper ends of two side columns 201, there are upper-layer sliding grooves 202. An active sliding frame assembly 3 is arranged in the upper-layer sliding grooves 202. On the side of the active sliding frame assembly 3 away from the steel reinforcement cage 10, there is a guiding pulley assembly 4. The guiding pulley assembly 4 is arranged on the lower-layer sliding groove 203, and the lower-layer sliding groove 203 is arranged on the inner surface of the side column 201 on the side away from the steel reinforcement cage 10. The supporting rod 9 can be rotated through the rotating shaft 7 to drive the supporting rod 9 to be clamped on the upper-layer sliding groove 202, which can limit the movement of the active sliding frame assembly 3. The steel reinforcement cage 10 is attached to the two slide rails formed by the C-shaped slide bar 6 and the slide rod 301 of the active sliding frame assembly 3 and slides into the inclined hole 11 along the slide rails by its own weight.
[0051] As Figure 13-18 shown in the figure, a first steel wire rope 206 is arranged on the first fixed pulley 205. One end of the first steel wire rope 206 is connected to the first hoist 207, and the other end of the first steel wire rope 206 is connected to the guiding pulley assembly 4. The first hoist 207 can control the raising or lowering of the guiding pulley assembly 4, and drive the first steel wire rope 206 to pull the guiding pulley assembly 4 by controlling the first hoist 207.
[0052] Preferably, a second steel wire rope 210 is arranged on the second fixed pulley 209. One end of the second steel wire rope 210 is connected to the second hoist 211, and the other end of the second steel wire rope 210 is connected to the steel reinforcement cage 10. The second hoist 211 can control the steel reinforcement cage 10. First, lower the guiding pulley assembly 4 and drive the active sliding frame assembly 3 to descend into the hole, and then lift and place the steel reinforcement cage 10 on the two slide rails formed by the C-shaped slide bar 6 and the slide rod 301 of the active sliding frame assembly 3. The steel reinforcement cage 10 moves along the C-shaped slide bar 6 and the active sliding frame assembly 3 into the inclined hole 11.
[0053] Preferably, the active sliding frame assembly 3 includes two slide rods 301. A connecting curved rod 302 is arranged between the two slide rods 301. Slide frame slide shafts 303 are also arranged on the two slide rods 301. Slide frame rolling bearings 304 are arranged at both ends of the slide frame slide shafts 303, and the slide frame rolling bearings 304 are embedded in the upper-layer sliding grooves 202. The active sliding frame assembly 3 can be aligned with the already drilled inclined hole 11, and the active sliding frame assembly 3 is driven by the guiding pulley assembly 4 to enter the inclined hole 11 along the wall of the inclined hole 11.
[0054] Preferably, the guiding pulley assembly 4 includes a guiding tube 401. At the lower end of the guiding tube 401, there is a movable hoop 402. Inside the guiding tube 401 at the upper end of the movable hoop 402, there is an opening 403. At the upper end of the opening 403, there is a pulley sliding shaft 404. At both ends of the pulley sliding shaft 404, there are pulley rolling bearings 405. The pulley rolling bearings 405 are embedded in the lower layer sliding groove 203. On the guiding tube 401, there is a key 406, and the key 406 is arranged on one side of the guiding tube 401 close to the upper layer sliding groove 202. The guiding pulley assembly 4 can move on the lower layer sliding groove 203. By clamping the movable carriage assembly 3 with the key 406, it can drive the movable carriage assembly 3 to move into the inclined hole 11. When the steel reinforcement cage 10 is lowered completely, the movable carriage assembly 3 is lifted to a height exceeding that of the support rod 9, and the support rod 9 is rotated and clamped in the upper layer sliding groove 202 to limit the movement of the movable carriage assembly 3. Thus, the conduit can be fixed by the movable hoop 402 at the bottom end of the guiding tube 401, and the guiding pulley assembly 4 drives the conduit to move up and down along the inclined hole 11, thereby pouring concrete.
[0055] Preferably, the length of the carriage sliding shaft 303 is the same as the length of the pulley sliding shaft 404 and the distance between the two side columns 201. The lengths of the carriage sliding shaft 303 and the pulley sliding shaft 404 should neither be too large nor too small, and need to be accurately clamped in the upper layer sliding groove 202 and the lower layer sliding groove 203 to achieve the up and down movement of the movable carriage assembly 3 and the guiding pulley assembly 4.
[0056] Preferably, the height of the upper layer sliding groove 202 and the height of the lower layer sliding groove 203 are equal to the height of the side column 201. The upper layer sliding groove 202 and the lower layer sliding groove 203 need to ensure that the guiding pulley assembly 4 and the movable carriage assembly 3 can move up and down on them, and at the same time, ensure that the support rod 9 can be clamped in the upper layer sliding groove 202 to limit the movement of the movable carriage assembly 3.
[0057] Preferably, the direction of the arc of the arc-shaped connecting rod 8 faces the upper layer sliding groove 202. When the arc-shaped connecting rod 8 rotates, it rotates towards the upper layer sliding groove 202, thereby clamping the support rod 9 into the upper layer sliding groove 202 to limit the downward movement of the movable carriage assembly 3.
[0058] Preferably, the C-shaped sliding bar 6 is of a C-shaped groove structure, and the C-shaped sliding bar 6 wraps the sliding rod 301 of the movable carriage assembly 3. The sliding rod 301 is arranged in the C-shaped groove of the C-shaped sliding bar 6. The sliding rod 301 can slide up and down in the C-shaped sliding bar 6, and the movable carriage assembly 3 moves under the double restrictions of the C-shaped sliding bar 6 and the upper layer sliding groove 202.
[0059] When this structure works, first install the steel reinforcement cage 10, and then pour the concrete, so that the two working processes can be realized only through one structure. When installing the steel reinforcement cage 10, the movable carriage assembly 3 is aligned with the inclined hole 11, release the first hoist 207 to make the guiding pulley assembly 4 slide down. Under the action of gravity, the guiding pulley assembly 4 drives the movable carriage assembly 3 to slide down along the C-shaped slide bar 6 and the upper chute 202. When the guiding pulley assembly 4 slides to the bottom of the lower chute 203, the lower end part of the movable carriage assembly 3 enters the inclined hole 11. The slide rod 301 of the movable carriage assembly 3 and the C-shaped slide bar 6 form two slide rails. Use the second hoist 211 to lift the steel reinforcement cage 10 through the second fixed pulley 209.
