Abstract
The utility model relates to a pre-reaming flexible pile structure of an integral abutment bridge. The pre-reaming flexible pile structure of the integral abutment bridge is characterized by comprising the integral abutment bridge and supporting piles arranged on the lower portion of the integral abutment bridge, the supporting piles are buried in pre-reamed holes of a soil layer, the diameters of the pre-reamed holes are larger than those of the supporting piles, and gaps between the pre-reamed holes and the supporting piles are filled with elastic material layers. The pre-reaming flexible pile structure of the integral abutment bridge has the advantages that the gaps between the pre-reamed holes and the supporting piles are filled with the elastic material layers, the elastic material layers are made of an elastic plastic material, lateral restraint of the supporting piles is reduced, and horizontal anti-push-flexibility of the supporting piles is enhanced, so that the supporting piles have good deformation capacity.
Description
Technical field:
The utility model relates to a kind of pre-reaming flexible pile structure of Integral Abutment Bridge, is the construction for Integral Abutment Bridge, belongs to the bridge field.
Background technology:
Integral Abutment Bridge globality and anti-seismic performance are good, and be also a lot of to its mechanical property research and cases of engineering, and this bridge type is liked by engineering circles always; Yet the horizontal length travel of the generations such as the temperature of Integral Abutment Bridge superstructure, automobile brake must be received by substructure.So that stake one side tension, a side pressurized also can be so that stake tension pressurized on one side on one side when temperature raises when wherein temperature reduced, and the direction of tension and pressurized opposite direction during with the temperature reduction.The brake force of automobile also can be so that a reciprocal back and forth swing in addition, produce very large displacement, these displacements all need to be received by supporting pile, and soil has produced very large resistance to stake simultaneously, we will try every possible means to reduce this resistance like this, and the horizontal flexibility that increases stake.So its abutment foundation need to be by flexible pile (the external H shaped steel of generally using) supporting, the H Section-steel Piles has good deformability, basically can satisfy the requirement of distortion and resistance, but the consideration in China for economy, abutment foundation enlarges basis or concrete pile as main take rigidity, and piling bar is used few.But the horizontal deformation of concrete pile is starkly lower than piling bar.When adopting concrete pile, concrete pile is subject to the constraint of soil, and horizontal rigidity is too large, and concrete pile very easily ftractures after reciprocal distortion and causes the corrosion of reinforcing bar in this case.In a single day the reinforcing bar of supporting pile is corroded, and can affect the life-span of stake, and the safety of bridge is also brought very large hidden danger.
And existing conventional pile construction technology meeting is so that the abutment bearing pile horizontal rigidity of Integral Abutment Bridge is large, can not satisfy the horizontal temperature deformation requirement of whole bridge, the bridge that has limited the seamless bridge of monolithic is long, thereby has hindered application and the popularization of Integral Abutment seamless bridge.
In addition, when there is pile foundation in the side slope inboard, and during the pile laterally-loaded, there has been equally the similar problem of monolithic bridge supporting pile.
Summary of the invention:
The purpose of this utility model is to provide a kind of pre-reaming flexible pile structure of Integral Abutment Bridge, the pre-reaming flexible pile structure of this Integral Abutment Bridge is not only simple in structure, reasonable in design, and be conducive to reduce the horizontal resistance of supporting pile, increase the horizontal flexibility of supporting pile.
The pre-reaming flexible pile structure of the utility model Integral Abutment Bridge, it is characterized in that: comprise Integral Abutment Bridge and the supporting pile that is located at the Integral Abutment Bridge below, described supporting pile is embedded in the in advance reaming of soil layer, the hole of described in advance reaming is large than supporting pile stake footpath, filling elastic material layer in the space between in advance reaming and supporting pile.
The mixture layer that above-mentioned elastomeric layer is comprised of loose sand and rubbery chip.
Above-mentioned supporting pile cross section is circular.
Above-mentioned supporting pile cross section is square.
Above-mentioned rubbery chip is the reclaimed rubber fragment of being made by junked tire.
The job practices of the pre-reaming flexible pile of the utility model Integral Abutment Bridge, it is characterized in that: the pre-reaming flexible pile of described Integral Abutment Bridge comprises Integral Abutment Bridge and is located at the supporting pile of Integral Abutment Bridge below, described supporting pile is embedded in the in advance reaming of soil layer, the hole of described in advance reaming is large than supporting pile stake footpath, filling elastic material layer in the space between in advance reaming and supporting pile, during construction, elder generation is according to the in advance reaming of size of supporting pile, supporting pile is installed after the reaming, after stake stable performance to be supported is got off, in the space of in advance reaming and supporting pile, inject the filling elastic material layer that configures again, and tamp.
The diameter in the hole of above-mentioned in advance reaming is not less than the diameter of supporting pile or 1.5 times of the length of side, and is not more than a diameter or the length of side 3 times.
The degree of depth in the hole of above-mentioned in advance reaming is not less than 0.2 times of supporting pile length, is not more than 0.6 times of stake.
The mixture layer that above-mentioned elastomeric layer is comprised of loose sand and rubbery chip, wherein rubbery chip is the reclaimed rubber fragment of being made by junked tire, the allocation ratio of the mixture layer of loose sand and reclaimed rubber fragment is configured by 1:0.6.
The beneficial effects of the utility model: the utility model is by filling elastic material layer in the space between in advance reaming and supporting pile; elastomeric layer belongs to a kind of elastic-plastic material; the lateral restraint of supporting pile has been reduced; the anti-flexibility that pushes away of the level of supporting pile increases; make supporting pile have preferably deformability; when causing that owing to other loads such as temperature stake moves back and forth; stake extruding mixture layer; mixture layer can be out of shape on one side along with stake; so just reduced the horizontal resistance of stake, also namely increased the horizontal flexibility of supporting pile, the reclaimed rubber fragment that has used junked tire to make; play protection of the environment, take full advantage of the effect of resource.
