Abstract
The utility model relates to a construction engineering structure, and particularly relates to a pile-net composite foundation structure. The pile-net composite foundation structure is composed of a road embankment and a foundation, wherein the foundation is composed of a reinforcement region and an underlying bed; rigid piles are driven into the reinforcement region; the pile tops of the rigid piles are positioned at the boundary between the road embankment and the reinforcement region, and are sleeved with pile caps; a broken stone hardcore is paved on the boundary; and a geogrid is covered on the broken stone hardcore. The pile-net composite foundation structure has the characteristics of reasonable design, low construction cost, high bearing capacity, favorable deformation resistance and the like.
Description
Technical field
The utility model relates to a kind of building engineering structure, especially relates to a kind of stake net composite foundation structure.
Background technology
Stake net composite foundation structure is applied in the reinforced soft soil ground engineering of river levee bank transformation, its objective is in order to make this section of subgrade settlement distortion meet the requirement of non-fragment orbit settlement after construction limit value, as composite pile foundation, raft plate or box foundation are stretched in the upper end of stake, and formation is rigidly connected.Stake and inter-pile soil shared upper load are the fundamental differences of composite foundation and pile foundation.Rigid pile can be transmitted to bearing capacity is higher load with the better ground deep layer of resistance capacity to deformation, thereby has increased bearing capacity of foundation soil and reduced sedimentation and deformation.Meanwhile, owing to having utilized to a certain extent inter-pile soil to bear a part of upper load, intensity and the consumption of stake are reduced, and have saved the cost of engineering.
Summary of the invention
The utility model is mainly that construction cost is higher for the existing complex structure of prior art, and bearing capacity is less, the technical problem of the poor grade of resistance capacity to deformation, provides a kind of simple in structure, and construction cost is lower, bearing capacity is larger, and resistance capacity to deformation is stake net composite foundation structure preferably.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: stake net composite foundation structure is made up of embankment and ground, ground is made up of stabilization zone and substratum, in stabilization zone, squeeze into rigid pile, the stake top of rigid pile is positioned at the boundary of embankment and stabilization zone, the stake top cover of rigid pile has pile cover, boundary is covered with hardcore bed, is coated with geo-grid on hardcore bed.Regulate stake, native loading sharing except playing a part at stake net composite foundation medium stone bed course, also play the important function of subduing lateral force.The sandstone using due to hardcore bed is discrete material, and the lateral force that transmission is got off to superstructure has played decoupling function, has eliminated the adverse effect of lateral force to rigid pile.Set up pile cover on stake top, further facilitated designer to the stressed adjusting of pile body, strengthened the ability of stake net composite foundation control subgrade settlement distortion.After embankment filled soil reach a certain height, the load that the later stage applies will be directly delivered in rigid pile by geo-grid.
Therefore, the utlity model has the features such as design is more reasonable, and construction cost is lower, and bearing capacity is larger, and resistance capacity to deformation is better.
