Description

Technical Field

[0001] The utility model relates to the field of construction devices, in particular to a construction auxiliary device for pile foundation engineering. Background Technique

[0002] A deep foundation composed of piles and a pile cap (referred to as a cap) connecting the pile tops or a single-pile foundation connecting columns and pile foundations is referred to as a pile foundation. During the construction process of pile foundations, sleeves are usually set under the soft layer below the ground surface. The sleeves can protect the pile body from erosion and damage by surrounding soil or rocks. Especially in complex geological conditions or when the soil contains a large amount of impurities, the sleeves can prevent the surface of the pile body from being worn or corroded.

[0003] When the existing sleeves are installed, the sleeves are usually directly moved down and inserted into the ground. Due to the direct insertion and the friction between the sleeves and the soil, the rate of downward movement is reduced, and at the same time, the external wear of the sleeves is accelerated.

[0004] To solve the above problems, a construction auxiliary device for pile foundation engineering is proposed in this application. Content of the Utility Model

[0005] (I) Purpose of the Utility Model

[0006] To solve the technical problems in the background technique, the utility model proposes a construction auxiliary device for pile foundation engineering. By providing a brush roller mechanism, when the sleeve moves down, oil liquid is applied to increase the smoothness of the downward movement of the sleeve, and at the same time, the verticality of the downward movement of the sleeve is detected to increase the verticality after the downward movement.

[0007] (II) Technical Solution

[0008] To solve the above problems, the utility model provides a construction auxiliary device for pile foundation engineering, including a sleeve, and an installation ring is arranged on the outer periphery of the sleeve;

[0009] An installation block is fixedly installed on the installation ring, and the installation block is rotationally connected with a brush roller mechanism for brushing oil liquid on the sleeve through a torsion spring rotating shaft.

[0010] Preferably, the brush roller mechanism includes a rotating plate and a brush roller. One end of the rotating plate is rotationally connected with the installation block through a torsion spring rotating shaft. The inside of the brush roller is hollow, through holes are formed in the brush roller, one end of the brush roller is rotationally connected with a rotating plate through a rotating shaft, and the other end of the brush roller is rotationally connected with another rotating plate through a liquid inlet pipe.

[0011] Preferably, a cotton sleeve is fixedly sleeved on the outer periphery of the brush roller, and leakage holes corresponding to the through holes are formed in the cotton sleeve.

[0012] Preferably, the torsion spring rotating shaft is fixedly connected with a rotating disk, an indicating ring is rotatably sleeved on the outer periphery of the rotating disk, the indicating ring is fixedly connected with the mounting block, scales are arranged on the indicating ring, and an indicating arrow is arranged on the rotating disk.

[0013] Preferably, a positioning rod is slidably sleeved on the mounting ring.

[0014] The above technical solution of the present utility model has the following beneficial technical effects:

[0015] Place the mounting ring on the ground where the sleeve needs to be inserted, pass the sleeve through the middle of the mounting ring, the brush roller contacts the outer periphery of the sleeve, and pass oil through the liquid inlet pipe. The oil enters the brush roller. Then, as the sleeve moves downward, it drives the brush roller to brush the outside of the sleeve, increasing the smoothness of insertion and reducing the occurrence of friction damage. When the sleeve is tilted, the rotating plate rotates under the action of the torsion spring rotating shaft, driving the rotating disk to rotate, and the deflection phenomenon can be observed to judge the verticality of the sleeve's downward movement, which is conducive to timely adjustment.
