Embodiment Construction
[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0037] see figure 1 As shown, the embodiment of the present invention provides a construction method for clearing holes of inclined steel pipe piles and reducing the thickness of sediment. The method includes the following steps:
[0038] S1. Use a reverse circulation drilling rig to drill holes, lift the drill bit after completion, and start the gas lift reverse circulation system to remove slag;
[0039] Specifically, step S1 can be divided into the following steps:
[0040] S101. Place the reverse circulation drilling rig, strengthen the anchor point between the reverse circulation drilling rig 1 and the construction platform 2, check the inclination of the operation platform 4, measure the elevation of the construction platform 2 and the elevation of the reference point of the operation platform 4, and then install and lower the flat bott...
