Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a splash guard and mudguard for a four-axis mixing pile machine. Background Technology

[0002] In the construction of four-axis mixing piles, the typical operation process is as follows: start the mixing motor to make the mixer rotate and cut the soil while sinking, and at the same time turn on the grout pump to spray cement slurry into the soil. Through mixing, the cement slurry is fully mixed with the soil layer, and it is necessary to ensure that the mixing piles are evenly distributed and maintain a certain hole spacing. However, in projects with environmental protection requirements in the construction area, the problem of cement slurry splashing has gradually become prominent and has become a key factor affecting the surrounding environment.

[0003] In the current construction process, cement slurry splashing is mainly caused by three factors: First, the interaction between the mixing pile and the soil layer generates a large force, which directly causes the slurry to be thrown out or splashed up; second, when the soil layer is soft and has a high water content, the mixing pile is easy to move the slurry, further increasing the probability of splashing; third, aging equipment, severe wear or improper maintenance can cause the mixing pile to vibrate and shake during construction, thereby aggravating slurry splashing and causing pollution to the surrounding environment. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a splash guard for a four-axis mixing pile machine, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a splash guard for a four-axis mixing pile driver, comprising a mud guard and a pile driver fixing frame, wherein a fixing sleeve and a supporting inclined sleeve are welded on the pile driver fixing frame, the fixing sleeve is arranged perpendicularly to the pile driver fixing frame, and the supporting inclined sleeve is inclined to the pile driver fixing frame.

[0006] The mudguard is made of steel plate with a thickness of 3-5mm, and the inner side is welded with crisscrossing ribs with a rib spacing of 300-500mm, which can enhance the structural strength of the mudguard and prevent deformation caused by mud impact.

[0007] Specifically, the perpendicularity error between the fixed sleeve and the pile driver fixing frame does not exceed 1°, which can ensure the precise insertion of the embedded sleeve and the fixed sleeve, and ensure the stability of the mudguard in the construction state.

[0008] The mudguard has a C-shaped structure with embedded sleeves welded to both ends of its inner side. The embedded sleeves are compatible with the fixed sleeves and can be inserted into each other. The diameters of the embedded sleeves and the fixed sleeves are compatible. After insertion, the gap between the two does not exceed 2mm, which can enhance the vibration resistance of the mudguard in the construction state.

[0009] The mudguard has a movable buckle installed on its inner side below the embedded sleeve;

[0010] The guardrail is fixed to the pile driver body with bolts. The guardrail is made of φ50mm steel pipe, with a height of 1.2m and a guardrail spacing of 500mm. It can provide a stable support point for the support rod and also help prevent debris from falling into the construction area.

[0011] One end of the support rod can be detachably connected to the movable buckle, and the other end can be used with the guardrail to fix the mudguard to form a closed protective structure to prevent cement slurry from splashing. Alternatively, one end can be inserted into the inclined support sleeve and the other end can abut against the inner side of the mudguard to support and fix the mudguard. A steel wire rope is connected between the top side of the mudguard and the pile driver body. The steel wire rope is used for top auxiliary fixation when the mudguard is in the supported state, so that the mudguard can be used as a protective shed for cleaning the mixing shaft and repairing the drill bit and mixing blades.

[0012] The inclination angle between the support inclined sleeve and the pile driver fixing frame is 30°-60°. With the support rod, the mudguard can be raised to a horizontal state, forming a stable protective canopy structure.

[0013] The wire rope is made of high-strength steel cable with a diameter of not less than 10mm and a breaking strength of not less than 10kN. It can withstand the vertical tension when the mudguard is supported, ensuring the safety of the protective shed.

[0014] In summary, the present invention has the following main advantages: Through a detachable and convertible mudguard structure, the present invention forms a closed protective barrier during the construction of four-axis mixing piles. This barrier directly blocks cement slurry splashes caused by the interaction between the mixing pile and the soil layer, the movement of mud slurry due to loose soil, or equipment vibration. This solves the problem of cement slurry polluting surrounding buildings, walls, and the ground environment in projects with environmental protection requirements, thus meeting environmentally friendly construction standards. The mudguard can be easily disassembled and reassembled, achieving two functional conversions: during construction, it acts as a splash barrier to protect the surrounding environment; when erected, it serves as a protective shed, providing safe operating space for cleaning the mixing shaft and repairing the drill bit and mixing blades. This avoids the cost of separately configuring protective facilities, improves the overall utilization rate of the equipment, and reduces the overall cost of construction and maintenance.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The embodiments of the present invention will now be described.

[0023] Example

[0024] like Figure 1-5 As shown in the figure, this embodiment discloses a specific installation, use and conversion method of a splash guard for a four-axis mixing pile machine, which aims to solve the problem of cement slurry splashing during the construction of four-axis mixing piles and realize the multi-functional reuse of the splash guard.

[0025] Component fabrication and initial installation

[0026] Installation of foundation components for pile driver: Weld two sets of fixing sleeves 2 and supporting inclined sleeves 5 to the pile driver fixing frame 8 of the four-axis mixing pile driver, respectively, to ensure that the welding is firm. The verticality error between the fixing sleeve 2 and the pile driver fixing frame 8 shall not exceed 1°, while the supporting inclined sleeve 5 and the pile driver fixing frame 8 shall be fixed by inclined welding.

[0027] At the same time, guardrail 6 is installed on the pile driver. The guardrail 6 is made of φ50mm steel pipe, 1.2m high, with a guardrail spacing of 500mm, and is fixed to the pile driver body with bolts.

[0028] Preparation and assembly of mudguard 1: According to the size of the four-axis mixing pile machine, C-shaped mudguard 1 is made. Embedded sleeves 3 are welded to both ends of the inner side of mudguard 1. The two sets of embedded sleeves 3 correspond to the fixed sleeves 2 and can be inserted into each other. Movable buckles 4 are installed below the embedded sleeves 3.

[0029] Use of mudguards during construction

[0030] Assembly process: Insert the embedded sleeve 3 of the mudguard 1 into the fixed sleeve 2 on the pile driver fixing frame 8 so that the mudguard 1 fits against the front of the pile driver. Connect one end of the support rod 7 to the movable buckle 4 and the other end to the guardrail 6.

[0031] Functionality: During the construction of the four-axis mixing pile, the mixer rotates to cut the soil and sinks, the grout pump sprays cement slurry, and the mudguard 1 forms a closed barrier to block the splashing mud caused by the interaction between the mixing pile and the soil layer, the movement of mud slurry caused by the loose soil layer, or the vibration of the equipment, thus protecting the surrounding buildings, walls and ground environment from pollution.

[0032] Mudguard 1 conversion under maintenance conditions

[0033] Conversion Operation: Remove the movable buckle 4, disconnect the support rod 7 from the guardrail 6, remove the support rod 7 from the movable buckle 4, pull out the connection between the embedded sleeve 3 of the mudguard 1 and the fixed sleeve 2, insert one end of the support rod 7 into the support inclined sleeve 5 on the pile driver fixed frame 8 and fix it, connect one end of the wire rope 9 to the top lifting ring of the mudguard 1, and fix the other end of the wire rope 9 to the fixed bracket on the top of the pile driver, adjust the tension of the wire rope 9 to make the mudguard 1 horizontally supported, at which time the other end of the support rod 7 abuts against the inside of the mudguard 1.

[0034] Functionality: The raised mudguard 1 forms a protective canopy, providing a safe operating space for cleaning the mixing shaft and repairing the drill bit and mixing blades. This prevents residual mud from falling or tools from falling during maintenance, thus avoiding safety hazards. At the same time, combined with regular equipment maintenance, such as replacing worn bearings and adding grease, it can further reduce equipment vibration during construction and reduce the risk of mud splashing.

[0035] This embodiment achieves rapid disassembly and functional conversion of the mudguard 1 through modular design, which is suitable for various four-axis mixing pile construction scenarios with environmental protection requirements. The installation efficiency is improved by 30%, and the mud splash control rate reaches more than 90%.
