Description

Technical Field

[0001] This utility model relates to the field of pile foundation construction technology, specifically to a rapid construction structure for large-diameter rock-socketed piles. Background Technology

[0002] In the process of infrastructure construction, pile foundations are widely used, from building and bridge foundation piles to landslide control and anti-slide piles. Pile foundations are mainly divided into two parts: pile hole excavation and reinforced concrete pouring. For the construction of pile holes, manual excavation or rotary drilling rig drilling is currently the main methods. Manual excavation of pile holes has high safety risks and long construction time. Rotary drilling rigs have high efficiency, but the cost of bringing rotary drilling rigs to and from the site is high, and they are also constrained by space, road and other conditions.

[0003] Among them, announcement number CN109914395B discloses a rapid construction method and structure for large-diameter rock-socketed piles. This method involves completing the reinforced concrete support of the overburden wall and pre-splitting boreholes around the pile in the bedrock section through ground drilling and trenching. During bedrock excavation, in conjunction with the pre-splitting boreholes, wedges placed in the bedrock boreholes are used to split the bedrock by ground impact, completing the rock excavation of the rock-socketed portion of the pile. This invention is suitable for pile foundation construction with different cross-sectional shapes, and is particularly suitable for the construction of large-diameter medium-hard rock-socketed piles.

[0004] However, before construction, a reinforced concrete retaining wall needs to be pre-cast around the pile foundation. Due to the large construction volume, the construction time of the reinforced concrete retaining wall is long. In addition, the manual excavation of the pile foundation will result in a long construction time and low construction efficiency.

[0005] Therefore, it is necessary to invent a rapid construction structure for large-diameter rock-socketed piles to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a rapid construction structure for large-diameter rock-socketed piles to solve the problems of long construction time and low construction efficiency in the technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rapid construction structure for large-diameter rock-embedded piles, comprising a bedrock layer, a protective groove being formed inside the bedrock layer, multiple sets of steel structure columns being inserted and fixedly connected inside the protective groove, multiple sets of blasting holes being formed on the surface of the bedrock layer at positions inside the protective groove, and a slag removal assembly and a dust suppression assembly being installed on the upper side of the bedrock layer. The slag removal assembly includes a gantry crane, a winch, a lifting cable, a suspended basket, a linear guide rail, and positioning rollers. The dust suppression assembly includes a water supply pipe, an installation frame, a rotating shaft, a spray pipe, a water guide pipe, and an atomizing nozzle.

[0008] By adopting the above technical solutions, steel structure columns are used to replace reinforced concrete retaining walls to support the side walls of the foundation pit, improving construction efficiency and convenience. At the same time, blasting technology is used to excavate the foundation pit, and the steel structure columns can effectively block the impact force generated by the blasting, avoiding damage to the side walls of the foundation pit and effectively increasing the excavation speed. The slag removal assembly is used to transport the stone debris out of the foundation pit, and the dust suppression assembly is used to suppress the dust generated during the excavation process, improving the cleanliness of the surrounding environment.

[0009] Optionally, the upper ends of multiple sets of steel structure columns are fixedly connected with steel structure fixing rings.

[0010] By adopting the above technical solution, multiple sets of steel structure columns are closely arranged inside the protective groove, and steel structure fixing rings are used to fix the upper ends of the multiple sets of steel structure columns, thereby improving the stability of the steel structure columns.

[0011] Optionally, steel structure support rings are welded and fixed to the inner side of multiple sets of steel structure columns, and multiple sets of steel structure support beams are welded and fixed to the inner wall of the steel structure support rings.

[0012] By adopting the above technical solution, as the foundation pit is excavated downwards, steel structure support rings are welded to the inner side of multiple sets of steel structure columns at regular intervals. The steel structure support rings, together with the steel structure support beams, support and fix the steel structure columns, thereby improving the stability of the steel structure columns.

[0013] Optionally, the gantry crane is fixed to the upper side of the foundation pit inside the bedrock layer, and two sets of winches are installed on the lower side of the upper crossbeam of the gantry crane.

[0014] Optionally, the winch is equipped with a lifting cable inside, and the basket is fixedly connected to the lower end of the lifting cable.

[0015] By adopting the above technical solution, the height of the suspended basket can be adjusted by winding and unwinding the lifting cable with a winch, and the stone debris inside the foundation pit can be transported upwards.

[0016] Optionally, linear guide rails are fixedly connected to both the front and rear sides of the upper beam of the gantry crane, and multiple sets of positioning rollers are rotatably connected to the upper end of the winch. The slots on the surface of the positioning rollers are respectively engaged with the surfaces of the front and rear sets of linear guide rails.

[0017] By adopting the above technical solution, the surface of the winch is equipped with a drive component. The drive component drives the positioning roller to rotate, thereby adjusting the position of the winch and moving the basket to one end of the crossbeam in the gantry. At this time, the engineering vehicle can be parked, and the material inside the basket can be directly dumped into the engineering vehicle, effectively improving the convenience of waste transportation.

[0018] Optionally, water supply pipes are fixedly connected to the upper surface of the bedrock layer at both the front and rear sides of the foundation pit. Multiple sets of mounting brackets are installed on the sides of the water supply pipes. A rotating shaft is rotatably connected to the upper end of each mounting bracket, and a spray pipe is fixedly connected to the middle of the rotating shaft.

[0019] By adopting the above technical solution, the water supply pipe is used to transport water, and the spray pipe can be rotated around the mounting frame via a rotating shaft to adjust the angle of the spray pipe.

[0020] Optionally, a water guide pipe is fixedly connected to one outer end of the spray pipe, and the end of the water guide pipe away from the spray pipe is fixedly connected to a water supply pipe. An atomizing nozzle is fixedly connected to one inner end of the spray pipe.

[0021] By adopting the above technical solution, the water guide pipe is used to transport the water flow inside the water supply pipe to the inside of the spray pipe. Then, the atomizing nozzle atomizes the water flow and sprays it outward to suppress the dust generated by the blasting, effectively improving the cleanliness of the environment. At the same time, it facilitates the rapid settling of dust, thereby facilitating rapid entry into the construction site.

[0022] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0023] 1. This utility model uses steel structure columns instead of reinforced concrete retaining walls to support the side walls of the foundation pit, improving construction efficiency and convenience. At the same time, the foundation pit is excavated using blasting technology, and the steel structure columns can effectively block the impact force generated by the blasting, avoiding damage to the side walls of the foundation pit, effectively improving the excavation speed of the foundation pit, and ensuring the safety of the foundation pit excavation.

[0024] 2. This utility model uses a winch, lifting cable and suspended basket to clean up the waste inside the foundation pit, and uses positioning rollers and linear guide rails to transport the waste directly into the engineering vehicle, thereby improving the speed of waste cleaning and transportation. At the same time, the dust suppression component makes the dust generated by blasting settle quickly, which facilitates rapid entry into the construction site and further improves the construction speed.

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] This utility model provides, for example Figures 1 to 3 The large-diameter rock-socketed pile rapid construction structure shown includes a bedrock layer 1. A protective groove 11 is provided inside the bedrock layer 1. Multiple sets of steel structure columns 13 are inserted and fixedly connected inside the protective groove 11. Steel structure fixing rings 14 are fixedly connected to the upper ends of the multiple sets of steel structure columns 13. Steel structure support rings 15 are welded and fixed to the inner side of the multiple sets of steel structure columns 13. Multiple sets of steel structure support beams 16 are welded and fixed to the inner wall of the steel structure support rings 15. Multiple sets of blasting holes 12 are opened on the surface of the bedrock layer 1 at the position inside the protective groove 11. A slag discharge assembly 2 and a dust suppression assembly 3 are installed on the upper side of the bedrock layer 1.

[0034] Before construction, the location of the pile foundation is first determined. Then, the excavation points of the protective trench 11 around the pile foundation are marked. Next, drilling equipment is used to drill holes at the excavation points of the protective trench 11. Two sets of adjacent holes need to overlap to ensure that multiple sets of holes can be effectively connected to form the protective trench 11. The width of the protective trench 11 is determined according to the outer diameter of the steel structure column 13. After the protective trench 11 is excavated, the steel structure column 13 is inserted into it in sequence. Two sets of adjacent steel structure columns 13 are tightly fitted together. After the steel structure columns 13 are laid in a circle, the bottom of the protective trench 11 is filled with waste slag to fix the bottom of the steel structure column 13. At the same time, steel structure fixing rings 14 are welded to the upper side of the steel structure column 13 to fix the upper end of the steel structure column 13 and improve the stability of the steel structure column 13.

[0035] After the support structure is installed, multiple sets of blasting holes 12 are drilled on the surface of the bedrock layer 1 inside the protective trench 11 using drilling equipment. Explosives are filled into the blasting holes 12 to blast the bedrock layer 1, thereby quickly excavating the foundation pit. Compared with reinforced concrete retaining walls, steel structure columns 13 can effectively protect the side walls of the foundation pit, avoiding damage to the side walls caused by the impact of the explosion. The support structure of steel structure columns 13, combined with blasting excavation technology, effectively improves the excavation efficiency of the foundation pit. At the same time, dust suppression components 3 are used to quickly suppress the dust generated by the blasting, facilitating rapid entry into the foundation pit for construction. Slag removal components 2 are used to quickly clean up the residue inside the foundation pit.

[0036] Meanwhile, during the excavation of the foundation pit, steel structure support rings 15 are welded to the inner side of multiple sets of steel structure columns 13 after each excavation. Steel structure support beams 16 are welded to the inner side of the steel structure support rings 15. The steel structure support rings 15 and steel structure support beams 16 work together to support and fix the steel structure columns 13, improving the stability of the steel structure columns 13. Furthermore, during the subsequent pile foundation pouring process, the steel structure support beams 16 and steel structure support rings 15 can be connected to form a temporary construction platform, facilitating construction within the foundation pit and further improving construction convenience.

[0037] See Figure 1 and Figure 4 The slag discharge assembly 2 includes a gantry crane 21, a winch 22, a lifting cable 23, a basket 24, linear guide rails 25, and positioning rollers 26. The gantry crane 21 is fixed to the upper side of the foundation pit inside the bedrock layer 1. Two sets of winches 22 are installed on the lower side of the upper crossbeam of the gantry crane 21. The lifting cable 23 is installed inside the winch 22. The basket 24 is fixedly connected to the lower end of the lifting cable 23. Linear guide rails 25 are fixedly connected to both the front and rear sides of the upper crossbeam of the gantry crane 21. Multiple sets of positioning rollers 26 are rotatably connected to the upper end of the winch 22. The slots on the surface of the positioning rollers 26 are respectively engaged with the surfaces of the front and rear sets of linear guide rails 25.

[0038] Specifically, the winch 22 adjusts the height of the suspended platform 24 by winding and unwinding the lifting cable 23. The suspended platform 24 is used to clean the waste inside the pit. The drive mechanism (which is existing technology and will not be described in detail here) drives the positioning roller 26 to slide to one side on the surface of the linear guide rail 25, moving the winch 22 and the suspended platform 24 to the edge of the pit. At this time, the engineering vehicle can be parked at the edge of the pit, and the suspended platform 24 directly discharges the cleaned waste into the engineering vehicle for cleaning, effectively improving the convenience and speed of waste cleaning.

[0039] See Figure 1 and Figure 5The dust suppression component 3 includes a water supply pipe 31, a mounting bracket 32, a rotating shaft 33, a spray pipe 34, a water guide pipe 35, and an atomizing nozzle 36. The water supply pipe 31 is fixedly connected to both the front and rear sides of the foundation pit on the upper surface of the bedrock layer 1. Multiple sets of mounting brackets 32 are installed on the side of the water supply pipe 31. The upper end of the mounting bracket 32 ​​is rotatably connected to the rotating shaft 33. The middle part of the rotating shaft 33 is fixedly connected to the spray pipe 34. The outer end of the spray pipe 34 is fixedly connected to the water guide pipe 35. The end of the water guide pipe 35 away from the spray pipe 34 is fixedly connected to the water supply pipe 31. The inner end of the spray pipe 34 is fixedly connected to the atomizing nozzle 36.

[0040] In addition, when blasting the bedrock layer 1 inside the foundation pit, the water pump is started to pump water into the water supply pipe 31. The water supply pipe 31 then delivers the water to the interior of multiple spray pipes 34 through the water guide pipe 35. The water is then atomized and sprayed out through the atomizing nozzle 36, allowing the dust generated by the blasting to settle quickly. This facilitates rapid entry into the foundation pit to clean up the waste residue, further improving construction efficiency.

[0041] The working principle of this utility model is as follows: Steel structure columns 13 replace reinforced concrete retaining walls to support the sidewalls of the foundation pit, improving construction efficiency and convenience. Simultaneously, blasting technology is used to excavate the foundation pit, and the steel structure columns 13 effectively block the impact force generated by the blasting, preventing damage to the sidewalls of the foundation pit, effectively increasing the excavation speed and ensuring the safety of the excavation. Meanwhile, the winch 22, lifting cable 23, and suspended platform 24 work together to clean up the waste inside the foundation pit. Positioning rollers 26 and linear guide rails 25 work together to directly transport the waste inside the suspended platform 24 to the engineering vehicle, increasing the speed of waste removal and transportation. Furthermore, the dust suppression component 3 allows the dust generated by the blasting to settle quickly, facilitating rapid on-site construction and further improving the construction speed.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
