Embodiment Construction
[0019] Arrange the pile positions on the soft foundation 3 to be reinforced and place the immersed tube 4 into the foundation 3 to the design depth, generally up to about 15 meters. The immersed tube method can be one of the following several types.
[0020] A. Set a conical spud can 5 at the lower end of the straight tube type immersed tube 4, then vibrate the immersed tube 4 to make it penetrate into the soft foundation soil 3,
[0021] B. First fill the lower end of the immersed tube 4 with bricks, and impact with the column hammer 6 to make the bricks plug the lower end of the immersed tube 4 tightly to form the anti-silt brick plug 7, and then continue to impact the brick plug 7, so that the immersed tube 4 follows the brick plug 7 into the foundation soil 3,
[0022] C. In the immersed tube 4, use the column hammer 6 to impact the foundation soil 3 to form a hole, and at the same time, the static pressure immersed tube 4 enters the foundation soil 3,
[0023] After the...

Abstract
The foundation reinforcing method for loose and soft soil includes depositing straight sunken tube into loose and soft soil through vibration or other process, throwing stuffing, such as sand and stone, mine refuse, clay, etc. mixed with cement and water, into the sunken tube, hammering to density and form piles, and final spreading stuffing cushion in the top of the piles to form composite foundation with high strength cement piles. The method is simple in construction and low in cost, and has wide application range and no environmental pollution.
Description
technical field [0001] The invention relates to a ground reinforcement method for soft soil layers. Background technique [0002] At present, in construction engineering, for the treatment of soft foundations such as silt, silty soil, loose sandy soil, silt, cohesive soil, plain fill, and miscellaneous fill, in addition to using pile foundations, vertical reinforcement composites can also be used. The foundation is reinforced, specifically, there are vibro pile method, sand pile method, cement fly ash gravel pile method, cement soil mixing method, etc. But existing pile-forming reinforcement method has the following steps as the disclosed construction technology of Chinese patent CN1153847A " a kind of concrete pile foundation construction technique and equipment ": A. the forming hole of pile body and upper bearing plate, B, bearing platform Production, C, the production of the lower bearing plate, D, the lower steel cage, pouring concrete into piles. The construction equ...
