Description

Technical Field

[0002] As pile foundation, bored cast-in-place piles have the characteristics of strong applicability, high bearing capacity, convenient construction, less impact on the environment, and no major difficulties in the construction of ultra-deep and ultra-long pile foundations. They are being used in more and more project constructions and are the most commonly used main pile type in pile foundation projects.

[0003] When carrying out cast-in-place pile construction on water, it is necessary to complete the steel casing pile sinking and burying in advance.

For example, application number 202311568487.9 discloses a rock-embedded steel pipe pile construction guide device, which does not solve the dependence of the water steel pipe pile hoisting on the construction platform. During the turnover process, it often takes a longer time to complete the construction platform before the guide device can be installed. The comprehensive use efficiency is still low, and its overall design is complex, and the assembly and manufacturing costs are high. Utility Model Content

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0031] Example:

[0032] like Figure 1-3 As shown, in this embodiment, a steel casing pile sinking positioning and guiding device is provided, including a base frame assembly, a transverse guide rail assembly 1, a longitudinal guide rail assembly and a pile holding limiter;

[0033] The number of the transverse guide rail assemblies 1 is more than two and they are arranged along the vertical direction of the base frame assembly;

[0034] Each transverse guide rail assembly 1 is provided with a longitudinal guide rail assembly, the transverse guide rail assembly 1 is slidably matched with the longitudinal guide rail assembly, and the transverse guide rail assembly 1 is provided with a limiting mechanism for limiting the movement of the longitudinal guide rail assembly;

[0035] Each longitudinal guide rail assembly is provided with a pile-holding limiter, the pile-holding limiter is slidably matched with the longitudinal guide rail assembly, and the longitudinal guide rail assembly is provided with a limit mechanism for limiting the movement of the pile-holding limiter;

[0036] The pile-holding limiter is provided with a pile-holding limit part which matches with the steel casing.

[0037] The steel casing pile sinking positioning and guiding device of this embodiment has a base frame assembly fixed to the hull 4 of the barge, and at the same time cooperates with the steel casing through the pile holding limiter of the pile holding limiter, and uses the crawler crane on the barge to cooperate with the vibrating hammer to hit the steel casing, which solves the limitation that the traditional water steel casing pile sinking construction must use a large-scale special pile driving ship or set up a construction platform, and effectively reduces the investment cost of materials, ship machinery and equipment. At the same time, because the position of the pile holding limiter relative to the hull 4 of the barge can be adjusted, specifically by sliding the longitudinal guide rail assembly on the transverse guide rail assembly 1, and the pile holding limiter on the longitudinal guide rail assembly. In this way, the guiding position of the steel casing can be adjusted in conjunction with the GPS positioning device, and the precise positioning and adjustment of the steel casing is achieved, which reduces the requirements for the positioning accuracy of the barge ship movement, saves the time for the ship movement positioning and anchor cable laying, and improves the comprehensive efficiency of steel casing pile sinking.

[0038] The specific structure of the base frame assembly of this embodiment is as follows:

[0039] It includes a horizontal base frame 2 and a vertical base frame 3. An installation and fixing portion connected to the hull 4 is formed between the horizontal base frame 2 and the vertical base frame 3. The transverse guide rail assembly 1 is arranged from top to bottom along the extension direction of the vertical base frame 3. The transverse guide rail assembly 1 at the uppermost end is connected to the horizontal base frame 2 to form an integrated structure.

[0040] The horizontal base frame 2 is fixedly mounted on the horizontal end surface of the hull 4 of the barge, and the vertical base frame 3 is fixedly mounted on the vertical end surface of the hull 4 of the barge.

[0041] Because the transverse guide rail assembly 1 is arranged from top to bottom along the extension direction of the vertical base frame 3, each transverse guide rail assembly 1 is provided with a pile limiter. When the pile limiter cooperates with the steel casing along the extension direction of the steel casing, it can provide effective lateral constraints during the steel casing pile sinking process, which can reduce the risk of pile position deviation and verticality exceeding the limit caused by uneven distribution of geological soil layers and isolated rocks during the steel casing pile sinking process, and improve the accuracy and verticality of steel casing pile sinking.

[0042] In this embodiment, there are two horizontal base frames 2 which are arranged in parallel. A vertical base frame 3 is provided at the bottom of the horizontal base frame 2 .

[0043] At the same time, a first reinforcing rod 5 is provided between two lateral guide rail assemblies 1 arranged vertically along the extending direction of the vertical base frame 3. The above structure can enhance the stability of the overall structure.

[0044] In this embodiment, the specific structure of the sliding cooperation between the transverse guide rail assembly 1 and the longitudinal guide rail assembly and the sliding cooperation between the pile holding limiter and the longitudinal guide rail assembly is as follows:

[0045] More than two sliding assemblies are respectively provided on the longitudinal guide rail assembly and the pile-holding limiter. The sliding assembly includes two sliding seats 6. The sliding seats 6 are provided with pulley members 7. A sliding fitting portion is formed between the pulley members 7 of the two sliding seats 6.

[0046] A guide rail portion 8 is provided on the transverse guide rail assembly 1 and the longitudinal guide rail assembly. The cross section of the guide rail portion 8 is T-shaped and is slidably matched with the guide rail portion 8 .

[0047] The specific structure of the limiting mechanism of this embodiment is as follows:

[0048] The limiting mechanism includes two limiting components, and the limiting components include a limiting part 9 and an adjusting rod 10. A limiting portion for limiting the movement of the longitudinal guide rail assembly and the pile limiter is formed between the two limiting components. The limiting part 9 is slidably matched with the guide rail part 8, and the adjusting rod 10 is connected to the two limiting parts 9. Threaded locking nut parts 11 are provided at both ends of the adjusting rod 10.

[0049] The above limiting principle is to operate the locking nut 11 to move the adjusting rod 10 and approach the limiting member 9, so that the limiting member 9 exerts a force on the guide rail 8, so that the limiting member 9 is relatively stably fixed to the guide rail 8, thereby playing a limiting role.

[0050] The longitudinal guide rail assembly of this embodiment includes two longitudinal guide rail members 12, the longitudinal guide rail members 12 are provided with guide rail portions 8, and a plurality of second reinforcing rods 13 are provided between the two longitudinal guide rail members 12. The above structure can enhance the stability of the overall structure.

[0051] The specific structure of the pile-holding limiter of this embodiment is as follows:

[0052] The pile-holding limiter comprises a pile-holding limit frame 14 and a pile-holding limit rod 15 . The pile-holding limit frame 14 has an opening 16 of a U-shaped structure. The pile-holding limit rod 15 is arranged at the opening of the opening 16 . The pile-holding limit rod 15 and the opening 16 form a pile-holding limit part.

[0053] Specifically, the pile holding limit frame 14 is provided with a slot 17 matched with the pile holding limit rod 15 , and the pile holding limit frame 14 is also provided with a latch 18 , which passes through the slot 17 and is connected to the pile holding limit rod 15 .

[0054] Specifically, guide rollers 19 are provided on the inner wall surface of the opening 16 and the pile-holding limiting rod 15 , and the guide rollers 19 are arranged in the pile-holding limiting portion.

[0055] The operation of the pile holding limiter and the steel casing in this embodiment is as follows:

[0056] First, remove the latch 18 to release the connection between the pile holding limit rod 15 and the pile holding limit frame 14, then remove the pile holding limit rod 15, and after the opening 16 is matched with the steel casing, match the pile holding limit rod 15 with the slot 17 of the pile holding limit frame 14 to make the opening of the opening 16 in a closed state, and then use the latch 18 to pass through the slot 17 and connect with the pile holding limit rod 15. The above operation is quick. At the same time, multiple pile holding limiters can provide effective lateral constraints during the steel casing pile sinking process. It can reduce the risk of pile position deviation and verticality exceeding the limit caused by uneven distribution of geological soil layers and boulders during the steel casing pile sinking process. The guide roller 19 provided therein can also play a guiding role, reduce the friction of the guide, and make the steel casing pile sinking process smoother.

[0057] To sum up, the steel casing pile sinking positioning and guiding device of the present embodiment has a reasonable structural design. The guiding device is fixed on the hull 4 of the barge, and the steel casing is lifted and driven by the crawler crane on the barge in cooperation with a vibratory hammer, which solves the limitation that the traditional water steel casing pile sinking construction must adopt a large-scale special pile-driving ship or set up a construction platform, effectively reducing the investment cost of materials and ship machinery and equipment. At the same time, the position of the pile limiter relative to the hull 4 of the barge can be adjusted, and the guiding position of the steel casing can be adjusted, which reduces the requirements for the positioning accuracy of the barge ship movement, saves the time for ship movement positioning and anchor cable laying, and improves the comprehensive efficiency of steel casing pile sinking.

[0058] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
