Abstract
Description
Technical Field
[0001] This utility model relates to the field of silt and soft soil foundation treatment, specifically an excavation mechanism for detecting the formation of cement-soil mixing piles. Background Technology
[0002] Cement-soil mixing pile composite foundation is a type of composite foundation that uses deep mixing machinery to forcibly mix cement as a curing agent with the foundation soil to form a vertically reinforced structure.
[0003] Seven days after the cement-soil mixing pile is formed, the pile head needs to be inspected. During the inspection, the soil around the pile head needs to be excavated to a depth of 0.5m to check the uniformity of the cement-soil mixing and to measure the pile diameter.
[0004] When excavating cement-soil mixing piles, the soil is usually shoveled manually around the pile head. However, this method has the following problems: 1. The pile head is easily damaged during manual shoveling, and a lot of soil will remain on the pile head after shoveling, which will affect the observation of the pile head; 2. Manual shoveling is labor-intensive and inefficient. Utility Model Content
[0005] The purpose of this utility model is to solve the above problems and provide an excavation mechanism for testing cement-soil mixing piles. It can realize automatic excavation around the pile head, reduce labor intensity, and at the same time ensure that no soil remains on the pile head after excavation, making it convenient for observation.
[0006] The technical solution adopted by this utility model to solve its technical problem is:
[0007] An excavation mechanism for testing the formation of cement-soil mixing piles includes a movable frame, a lifting ring disposed within the movable frame and moving up and down within the movable frame, and a rotating ring disposed within the lifting ring. The inner wall of the lifting ring is provided with a brush for cleaning the outer cylindrical surface of the pile head, and the lower end of the rotating ring is evenly provided with a plurality of hoe blades.
[0008] Furthermore, the movable frame is symmetrically equipped with lifting hydraulic cylinders that drive the lifting ring to rise and fall.
[0009] Furthermore, the movable frame is symmetrically provided with support beams, and the lower end of the support beams is provided with a guide rod that passes through the lifting ring and is slidably connected to the lifting ring.
[0010] Furthermore, a motor is provided at the lower end of the lifting ring, a gear is provided on the output shaft of the motor, and a rack that meshes with the gear is provided on the outer cylindrical surface of the rotating ring.
[0011] Furthermore, a plurality of support rods are evenly provided at the lower end of the rotating ring, and the hoe blade is installed at the lower end of the support rods.
[0012] Furthermore, both the lower end of the support rod and the blade of the hoe are provided with connecting plates, and the two connecting plates are connected by bolts.
[0013] The beneficial effects of this utility model are:
[0014] 1. This utility model includes a movable frame, a lifting ring disposed within the movable frame and moving up and down within the movable frame, and a rotating ring disposed within the lifting ring. The inner wall of the lifting ring is provided with a brush for cleaning the outer cylindrical surface of the pile head. The lower end of the rotating ring is evenly provided with several hoe blades. During the pile formation inspection of cement-soil mixing piles, the movable frame moves to the position of the cement-soil mixing pile, aligning the lifting ring with the pile. Then, it descends and fits onto the cement-soil mixing pile. The rotating ring rotates, and the hoe blades scoop up the soil around the cement-soil mixing pile, thereby achieving automatic excavation around the pile head, reducing labor intensity. Simultaneously, as the lifting ring rises and falls, it sweeps off the soil adhering to the cement-soil mixing pile, facilitating observation of the pile formation quality.
