Description

A pile head ring cutting machine for high-speed railway caps

technical field

The invention relates to the field of high-speed railway pier construction, in particular to a pile head ring cutting machine for high-speed railway caps.

Background technique

In the construction process of the high-speed rail cap platform, there are mainly the following construction steps: construction preparation→measurement and lofting→excavation of foundation pit→waterproof and drainage construction→pile head treatment→pile foundation inspection→cushion construction→reinforcement binding→formwork installation→concrete pouring Facilities → pouring platform concrete → concrete curing, dismantling → foundation pit backfilling;

Wherein, in the prior art, during the pile head processing process, the pile head is removed by mechanical cooperation with manual chiseling. After the foundation pit is excavated, the elevation of the pile top (in order to ensure a good connection between the pile foundation and the cap, the pile top should extend 10cm into the cap, and the ring cutting method is used to ensure the protective layer of the pile) is measured and set on the concrete side of the pile. and clearly marked. Step 1: Set a cutting line with a width of 1 to 3 cm above the pile top. Step 2: Manually cut a gap to the depth of the steel bar. It is convenient for subsequent pneumatic pick operations without damaging the protective layer of steel bars. Step 3: Pneumatic picks peel off the outer protective layer of the upper reinforcement. The fourth step: the steel bar is slightly bent to the outside, which is convenient for construction. Step 5: Drill the top break, the drill bit is horizontal or slightly upward, and the position is 2cm above the top line of the pile. Step 6: Remove the concrete from the pile head, use a crane or an excavator to hoist the pile head out and discard it to the slag yard, and then manually chisel out the pile top to the design elevation to ensure that the protective layer is not damaged. Step 7: The top of the pile is leveled, the top of the steel bar is formed into a hook, and the next process is carried out after the pile foundation is tested and passed.

The above steps can realize the treatment of the pile head, but it needs to be carried out manually for a long time with a pick, which has a relatively high labor intensity. After the end, it is very troublesome to manually bend the steel bars one by one; in view of this, there is an urgent need for an automated device that can process the pile heads.
