Embodiment 1

[0023] see Figure 1-2 As shown, in this embodiment, the present invention provides a method for cutting and retaining steel bars at the head of a concrete prefabricated pipe pile. The prefabricated pipe pile 2 includes a steel skeleton 1, an outer concrete 21 and an inner concrete 22, and the steel skeleton 1 is poured on the outer layer. Between the concrete 21 and the inner layer concrete 22; the construction equipment adopted includes a cutting machine 5, a saw blade 4 and a small saw blade 3; the saw blade 4 is located above the prefabricated pipe pile 2; the method for retaining the steel bar at the pile head includes the following steps:

[0024] S1, installing the saw blade machine 4 on the top of the prefabricated pipe pile 2;

[0025] S2, cutting the prefabricated pipe pile 2 in circles with the cutting machine 5, without damaging the steel bar skeleton 1 during the cutting process;

[0026] S3, install the small saw blade 3 on the saw blade machine 4, and cut the i...

Embodiment 2

[0030] This embodiment is similar to Embodiment 1, and further, the reinforced skeleton 1 described in this embodiment can be welded with the upper cap or the lightning protection system; the diameter of the small saw blade 3 in step S3 is smaller than the inner layer concrete 22 of the prefabricated pipe pile 2 The diameter of the prefabricated pipe pile 2 outer layer concrete 21 is removed by the ring cutting performed by the cutting machine 5 in step S2; the positions of cutting the outer layer concrete 21 and the inner layer concrete 22 in steps S2~S3 are corresponding.

Embodiment 3

[0032] This embodiment is similar to embodiment 1, and further, the working order of step S2 and step S3 described in this embodiment can be exchanged; Its pile head method for retaining reinforcement comprises the following steps:

[0033] S1, installing the saw blade machine 4 on the top of the prefabricated pipe pile 2;

[0034] S2. Install the small saw blade 3 on the saw blade machine 4, and cut the inner layer concrete 22 of the prefabricated pipe pile 2 in a circle through the small saw blade 3 without damaging the steel bar skeleton 1;

[0035] S3, cutting the prefabricated pipe pile 2 in circles with the cutting machine 5, without damaging the steel bar skeleton 1 during the cutting process;

[0036] S4. Pull out or knock out the cut outer layer concrete 21 and inner layer concrete 22 without damaging the steel skeleton 1 in the prefabricated pipe pile 2;

[0037] S5. Residual concrete on the prefabricated pipe pile 2 is removed.

Abstract

The invention discloses a method for cutting out concrete prefabricated pipe pile pile heads and retaining steel bars. The prefabricated pipe piles include a steel bar skeleton, outer concrete and inner concrete, and the steel bar skeleton is poured between the outer concrete and the inner concrete; the construction equipment used includes Cutting machine, sawing machine and small sawing blade; the sawing machine is located above the prefabricated pipe pile; the method for retaining the steel bar at the pile head includes the following steps: S1, installing the sawing machine on the top of the prefabricated pipe pile; S2, using the cutting machine to The ring cutting of the prefabricated pipe piles does not damage the steel skeleton during the cutting process; S3, install a small saw blade on the saw blade, and use the small saw blade to cut the inner concrete of the prefabricated pipe piles in a circle without damaging the steel skeleton ; S4, removing or knocking out the cut outer layer concrete and inner layer concrete without damaging the steel skeleton in the prefabricated pipe pile; S5, removing the residual concrete on the prefabricated pipe pile.

Description

technical field [0001] The invention relates to the field of methods for cutting prefabricated pipe piles, in particular to a method for cutting concrete prefabricated pipe piles and retaining steel bars at pile heads. Background technique [0002] At present, in the field of cutting prefabricated pipe piles, because most of the methods of cutting the excess concrete of prefabricated pipe piles are manual sledgehammers or hand-held cutting machines, although labor costs are reduced, there is a risk of destroying the internal steel structure. The consequences of this risk can be large or small. Seriously, it may lead to instability of the building structure and affect the safety of people's lives and property. In order to avoid this situation, a new method of cutting prefabricated pipe piles is needed, which is easy to use and does not damage The internal steel structure makes the overall building firm and safe, reducing unnecessary hidden dangers.
