Embodiment

[0038] like Figure 1-7 As shown, the method for excavating the ring groove of the uplift platform for the uplift pile on the building infrastructure includes steps:

[0039] Step 1, in pile hole 36 vertical hoisting is provided with excavation motor 1, is provided with at least two upper annular water jacket mounts 9 on the fuselage 8 of excavation motor 1, is installed on the described upper annular water jacket mount 9 Annular water jacket 4;

[0040] Step 2. The rotating shaft of the excavating motor 1 is connected to the excavating rotating shaft 2 through a coupling. An upper sealing ring sleeve 10 is provided on the upper end of the excavating rotating shaft 2, and a lower sealing ring sleeve 11 is provided on the lower end of the excavating rotating shaft 2. The middle part of the rotating shaft 2 is evenly distributed with three pairs of excavating fan knife installation holes 12, and each pair of excavating fan knife installing holes 12 is arranged in a staggered ma...

Abstract

The invention discloses an uplift pile table annular groove excavating method used for uplift piles on building foundation construction. Suction water pumps are connected to the outer end part of a water inlet pipe and the outer end part of a pulp discharging pipe through hoses, a bidirectional suction water pump is connected to the outer end part of an annular water sleeve in-out pipe, an excavating motor is put into a pile hole through a traction rope and arrives at a designated position in the formed pile hole, the bidirectional suction water pump is controlled to flush all annular water sleeves with water to make the water sleeves bulge, the excavating motor is fixed in the pile hole, the suction water pumps connected to the outer end part of the water inlet pipe and the outer end partof the pulp discharging pipe are started first, then the excavating motor is started, and the rotating speed of the excavating motor is controlled to be increased progressively to a high level from alow level until one uplift table annular groove is excavated. The purpose of excavating the uplift table annular grooves in a foundation of a round pile hole is achieved, and continuous action can beachieved.

Description

technical field [0001] The invention relates to the field of building construction equipment, in particular to a method for excavating ring grooves of an anti-uplift table for uplift-resistant piles on building infrastructure. Background technique [0002] Anti-lift piles are also called anti-floating piles, which refer to piles that are driven to counteract the buoyancy of the structure caused by water in the soil when the underground structure of the construction project is lower than the surrounding soil water level. [0003] In order to make the pile body have greater buoyancy resistance, engineers have designed various structures of uplift piles. The simplest kind of uplift pile is a cylindrical pile body driven in the ground. This kind of pile structure is easy to implement. ,is widely used. In order to make the cylindrical structure pile body have greater buoyancy resistance, multiple annular anti-uplift platforms can be set on the cylindrical structure pile body, an...
