Description

Technical Field

[0001] The utility model relates to the technical field of foundation construction, in particular to a device for preventing deviation of pile foundation construction in civil engineering. Background Art

[0002] In construction, piling is an important foundation project. During the piling process, the pile body is prone to deviation due to various reasons, thus affecting the quality and safety of the project. In the existing technology, mechanical structures can be used to guide foundation piles. However, the existing guiding structure is relatively simple, and its main body is a fixed guide tube. It cannot adapt to foundation piles of different diameters, resulting in significant limitations in its use.

[0003] Furthermore, the guide structure needs to be used in conjunction with a horizontal platform, and lacks a level adjustment function. The additional steps required by the prefabricated horizontal platform will also reduce the efficiency of foundation construction. Utility Model Content

[0008] The base is provided with a fixing assembly for fixing the guide plate;

[0009] The base is provided with an adjustment component for adjusting the levelness of the base;

[0010] Any one of the limit plates is provided with a verticality sensor.

[0011] The above-mentioned anti-deflection device for civil engineering pile foundation construction is used. The device is placed at the marked point so that the opening is facing the marked point. The posture of the base is adjusted by adjusting the assembly to make the base horizontal. After the base is horizontal, the limit plate will be in a vertical state. The verticality sensor can detect whether the limit plate is vertical.

[0012] The base is fixed to the current posture through the positioning assembly, so that the limit plate remains vertical, and the foundation pile is placed between the limit plates. The limit plates are then propped open by the foundation piles. The bottoms of the foundation piles are mostly pointed, so the foundation piles are easily placed between the limit plates. The limit plates can accommodate foundation piles of different thicknesses. The limit plates can be driven to move by the pneumatic rods, so that the limit plates are close to each other and in continuous contact with the surface of the foundation piles.

[0013] After the limit plate is expanded, the guide plate is fixed by the fixing assembly, so that the position of the limit plate can be fixed. By cooperating with several limit plates, the foundation pile can be limited to keep the foundation pile vertical and prevent deviation.

[0014] Preferably, the fixing assembly includes a fixing ring, and several electric push rods are vertically arranged between the fixing ring and the fixing frame. The two ends of the electric push rods are respectively fixed to the fixing frame and the fixing ring. A rubber ring is provided at the bottom of the fixing ring, and the rubber ring is in contact with the upper side of the guide plate.

[0018] Preferably, a plurality of the limiting plates can form a vertical cylinder when in contact with each other.

[0019] Preferably, a lubrication assembly is provided on the base for delivering lubricating oil to the opposite surfaces of the plurality of limit plates.

[0020] Preferably, the lubrication assembly includes an oil tank and a delivery pump, both of which are arranged on a base, the oil extraction port of the delivery pump is connected to the oil tank, and the output end of the delivery pump is connected to a delivery pipe whose number is the same as the limit plate, and the delivery pipe is connected to a number of oil delivery heads, which pass through the limit plate, and the end of the oil delivery head is flush with the inner wall of the limit plate, and the delivery pipe is a hose.

[0021] The beneficial effects are:

[0022] 1. By cooperating with a plurality of limit plates and a pneumatic rod, foundation piles of different thicknesses can be accommodated between the limit plates. The pneumatic rod can drive the limit plates to move, so that the limit plates are close to each other and in continuous contact with the surface of the foundation pile, thereby enabling the device to adapt to foundation piles of different diameters. The guide plate is fixed by a fixing assembly, thereby fixing the position of the limit plate. The cooperation of the plurality of limit plates can limit the foundation pile, so that the foundation pile remains vertical and prevents deviation.

[0023] 2. Adjust the posture of the base by adjusting the components to make it level. The device can adapt to uneven ground and save the time required for prefabricating the platform. After the base is level, the limit plate will be in a vertical state. The verticality sensor can detect whether the limit plate is vertical.

[0024] 3. The lubricating oil can be transported to between the limit plate and the foundation pile through the lubricating assembly. The lubricating oil can reduce the friction between the foundation pile and the limit plate, thereby reducing the pile driving resistance and the wear of the limit plate.
