Embodiment Construction
[0011] The summary of the invention has described the specific implementation manner of the present invention in detail, does not repeat here, needs to explain as follows: 1. see figure 1 , figure 2 , under normal circumstances, the truncated concrete pile 12 needs to keep the pile main reinforcement 13 with a length of about 500 mm without cutting it. This section of steel reinforcement needs to be embedded in the pile cap that will be poured later. The concrete protective layer (concrete other than the pile main reinforcement) exposes the pile main reinforcement 13, and then the upper pile core concrete is excised from the pile cutting plane 14. The present invention designs 3 hydraulic shears up and down to achieve the purpose of peeling off the concrete protection layer. The concrete protective layer is only 50 mm thick, and the force applied by the hydraulic system 2 does not need to be very large, so the hydraulic shear B11 does not need to design a hydraulic system, an...

The invention provides a hydraulic shear for cutting off the head of a concrete pile. The hydraulic shear is mainly used for cutting off the head of the concrete pile in the field of constructional engineering. The hydraulic shear does not damage force-bearing main ribs of the pile, and the plane of the cut pile is neat, manual secondary finishing is not needed, the device is simple, and the manufacturing cost and the maintenance expenses are low. The hydraulic shear is mainly composed of hydraulic shear bodies A 1, pin rods 5, shafts 6, a hydraulic shear body B 11, hanging chains 16, a rotary table 17 and a hanging hook 18. According to the main working principle, the three hydraulic shear bodies are started first to peel off a concrete protection layer, the lower hydraulic shear body A 1 is then started, injection drill rods 4 of the hydraulic shear bodies A 1 continue to be injected into pile core concrete, annular cutters 3 of the hydraulic shear bodies A 1 accordingly conduct injection and start working at the same time, the uneven concrete protection layer at the position of a cut pile plane 14 is cut off, the portion, above the cut pile plane 14, of the pile core concrete will be forced to move upwards, and the concrete above the position of the cut pile plane 14 and the concrete below the position of the cut pile plane 14 are neatly separated.
Description
technical field [0001] The invention is mainly used for cutting concrete pile heads in the field of construction engineering. Background technique [0002] The currently authorized and applied for concrete pile cutting equipment patents do not consider the protection of the main reinforcement of the pile, and the plane of the pile cutting is uneven, requiring manual secondary repairs, and the equipment is complicated, and the manufacturing cost and maintenance cost are high. Contents of the invention [0003] The present invention solves the above-mentioned problems, it does not damage the stressed main tendon of the pile and the plane of the truncated pile is neat, does not need manual secondary trimming, and the equipment is simple, and the manufacturing cost and maintenance cost are low; the present invention mainly consists of hydraulic shears A ( 1), pin rod (5), shaft (6), hydraulic shear B (11), lifting chain (16), turntable (17), hook (18); hydraulic shear A (1) co...
