Abstract
The invention relates to a treatment method of a drainage pipe pile composite foundation. The treatment method comprises the following steps: arranging drainage pipe piles according to a certain distance in a soft clay foundation; arranging drainage cushion layers on the top surfaces of the drainage pipe piles or pile caps; when the pile caps are arranged on the top of the drainage pipe piles, arranging preformed holes on the pile caps so as to ensure that the pipe pile holes are communicated with the drainage cushion layers; and arranging a certain number of small holes penetrating through pipe walls on the pipe walls of the drainage pipe piles so that underground water in soil among the piles can flow into the pipe pile holes via the small holes and then is drained via the preformed holes and the drainage cushion layers on the pile caps. Therefore, by means of the treatment method of the drainage pipe pile composite foundation, the dissipation of excess pore water pressure in the soil among the piles can be enhanced, the soil compacting effect generated by pipe pile construction can be reduced, and the load carried by the soil among the piles or post-construction settlement caused by self weight of foundation soil can be reduced.
Description
Technical field
The present invention relates to a kind of method for processing foundation, be specifically related to a kind of method for processing foundation that can accelerate excess pore water pressure dissipation in the ground, belong to the foundation treatment technology field.
Background technology
Along with construction periods such as speedway, railway ground constantly shortens, allow that settlement after construction is more and more littler, but the construction pile tube can produce excess pore water pressure in ground in the cohesive soil ground, cause lateral displacement or earth heaving, just may cause engineering accidents such as broken pile, pile body inclining, engineering construction is produced adverse influence, in addition, prefabricated tubular pile pile composite foundation inter-pile soil is born load when big or foundation soil when being underconsolidated soil, there is excess pore water pressure in inter-pile soil, if vertical drainage body is not set between stake, the ground settlement after construction may be just bigger.
For fear of or reduce above-mentioned adverse effect, need in ground, be provided with earlier vertical drainage body usually, and adopt measures such as jumping pile constructing process, so just make the construction technology complexity, the construction costs height, the construction period is elongated.
Summary of the invention
The purpose of this invention is to provide a kind of excess pore water pressure of can accelerating in the ground and dissipate, reduce the treatment process of composite foundation of soil compaction effect and settlement after construction, adopt this ground processing method, can effectively shorten the construction period, reduce construction costs.
The object of the present invention is achieved like this:
A kind of gutter pile composite foundation processing method comprises the steps:
(1) aperture that runs through tube wall of some at first is set on draining pile tube tube wall;
(2) the draining pile tube that will be provided with aperture is then arranged according to a determining deviation in the soft clay ground;
(3) at draining pile tube end face drainage blanket is set at last, load application on drainage blanket, underground water flows in the draining pile tube stake hole by the aperture on the draining pile tube tube wall in the inter-pile soil, drains by drainage blanket.
Purpose of the present invention can also realize like this:
A kind of gutter pile composite foundation processing method comprises the steps:
(1) aperture that runs through tube wall of some at first is set on draining pile tube tube wall;
(2) the draining pile tube that will be provided with aperture is then arranged according to a determining deviation in the soft clay ground;
(3) at draining pile tube top pile cover is set at last, preformed hole is set on the pile cover, end face at pile cover is provided with drainage blanket, load application on the plumbing bed course, underground water flows in the draining pile tube stake hole by the aperture on the draining pile tube tube wall in the inter-pile soil, drains by the preformed hole on the pile cover, drainage blanket.
Gutter pile composite foundation processing method can promote the dissipation of the ultra-clean pore water pressure that tube pile construction, ground load, ground deadweight etc. produce in ground, thereby reduces soil compaction effect and reduce settlement after construction, improves workmanship.
Advantage of the present invention is:
(1) adopt the aperture that runs through tube wall is set on draining pile tube tube wall, underground water is drained, the ultra-clean pore water pressure is dissipated, thereby has reduced soil compaction effect and reduced settlement after construction, has improved workmanship.
(2) adopt in gutter pile composite foundation processing method, easy construction, easy to operate, reduced construction costs.
