Problems solved by technology
The rammer rams the hole first, and then the immersed tube can follow up and sink to the depth of the rammed hole, effectively supporting and protecting the wall of the hole to solve the problem of hole wall collapse; and even when encountering a local hard soil layer, Since the bottom of the immersed tube is no longer closed, it can still be operated with a large hammer force to ensure work efficiency

Embodiment Construction
[0014] The specific implementation manners of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.
[0015] like figure 1 , figure 2 As shown, the arm tube integrated crawler dynamic compaction replacement machine consists of a crawler chassis 1, a guide cylinder 5, an immersed tube 7, a leveling and pulling tube composite system, a lower lock ring assembly, an upper lock ring assembly, a dynamic compaction system, and a lock ring drive hydraulic pressure cylinder system. The crawler chassis 1 is used for the whole machine to walk, and a guide cylinder 5 is installed on it. The upper end of the guide cylinder 5 is equipped with an upper lock ring assembly, and the lower lock ring assembly can move up and down in the guide cylinder 5; the immersed tube 7 is sleeved on the guide cylinder 5 Inside, the immersed tube 7 is welded with a guide key 7a that restricts the circumferential rotation of the immers...

The invention relates to an arm tube fusion-type caterpillar-band dynamic compaction replacement machine, which belongs to the technical field of engineering machinery, is applicable to the reinforcement engineering of soft foundation and used as a special device for the dynamic compaction replacement operation. The dynamic compaction replacement machine consists of a caterpillar-band chassis, a guide cylinder, an immersed tube, a leveling unplugging tube composite system, a lower lock ring assembly, an upper lock ring assembly, a dynamic compaction system and a lock ring driving hydraulic cylinder system. The immersed tube is used for substituting a conventional arm support so as to realize the fusion of the arm tube; when in dynamic compaction operation, the immersed tube can be sunken to the compaction depth; the immersed tube also can be hoisted in a brake manner, and the immersed tube is compressed by the brake inertial power of a compaction hammer to be immersed; not only can the leveling of the entire machine be realized, but also the sufficient tube unplugging force can be provided through the leveling tube unplugging composite system, the entire machine can be raised, and the forced tube unplugging function is realized. The arm tube fusion-type caterpillar-band dynamic compaction replacement has the advantages of convenience and rapidness in realization, low cost and applicability to different soil layer characteristics.
Description
technical field [0001] The invention belongs to the technical field of engineering machinery, and relates to a dynamic compaction replacement machine suitable for soft ground reinforcement engineering and used as special equipment for dynamic compaction replacement operations. Background technique [0002] At present, reinforced concrete cast-in-place piles are often used in soft foundation reinforcement construction, and the main hole-forming methods include bored cast-in-place piles and immersed pipe cast-in-place piles. Bored piles are usually constructed with an auger drilling machine, but the hole wall is prone to collapse, it is difficult to pour into the hole, and the quality of concrete pouring is unstable. Immersed tube cast-in-place piles, the steel sleeves are forced into the foundation, and then the piles are formed by hammering or vibrating while pouring concrete, which is convenient for lowering the reinforcement cage and pouring concrete, and the quality of th...
