Abstract

The utility model discloses a foundation arrangement structure of vibro-replacement stone long piles and vibro-replacement stone short piles. The foundation lower part comprises three soil layers, which are respectively a cohesive soil layer, a silty-fine sand layer and a fine sand layer from top to bottom. The upper part of the cohesive soil layer is paved with a graded broken stone cushion comprising long piles and short piles. The long piles are distributed at equal distance along the transverse and longitudinal directions, and the connecting lines of the centers of each four adjacent long piles form a square. The center of each square is provided with one short pile. The pile heads of the long piles and short piles both traverse through the graded broken stone cushion, and are disposed on the same horizontal surface. The other end of each long pile extends to the fine sand layer, and the other end of each short pile extends to the silty-fine sand layer. The foundation arrangement structure of vibro-replacement stone long piles and vibro-replacement stone short piles is advantageous in that with the arrangement of the foundation arrangement structure, the requirement of the upper part structural calculation on foundation bearing capacity is met, and investment is saved.

Description

The ground arrangement of the long and short stake of a kind of vibro-replacement stone
Technical field
The utility model relates to a kind of ground arrangement, particularly relates to the ground arrangement of a kind of rubble vibrosinking pile length stake.
Background technology
For Inner Mongol Wula Shan Mountain power plant geological condition, basic bottom is divided into three layers of soil layer, is respectively viscous soil horizon, fine sand layer, fine sand layer.Wherein viscous soil horizon and fine sand layer low bearing capacity, and there is liquefaction phenomenon in fine sand layer.For this kind geological condition, general processing mode is pile foundation, replacement stone pile composite foundation, but the pile foundation cost is high, waits the long broken stone pile waste of stake serious.
The utility model content
The purpose of this utility model is to provide the ground arrangement of a kind of rubble vibrosinking pile length stake.
the purpose of this utility model is implemented by following technical scheme, a kind of vibro-replacement stone is long, the ground arrangement of stub, the bottom, basis is divided into three layers of soil layer, be respectively viscous soil horizon from top to bottom, fine sand layer and fine sand layer, described viscous soil horizon top is equipped with granular cushion, it comprises long stake and stub, described long stake is along horizontal and vertical equidistant distribution, the line of centres of every adjacent four described long stakes consists of square, each described foursquare center is provided with a described stub, the pile crown of described long stake and the pile crown of described stub all pass described granular cushion, and the pile crown of described long stake and the pile crown of described stub are on same level, the other end of described long stake extends to described fine sand layer, the other end of described stub extends to described fine sand layer.
Described long stake is the long stake of vibro-replacement stone, and described stub is the vibro-replacement stone stub.
The utility model has the advantage of, adopt the ground arrangement of rubble vibrosinking pile length stake, namely reached the requirement of superstructure calculating to bearing capacity of foundation soil, saved again investment.
Description of drawings
Fig. 1 is that schematic diagram is arranged in the long and short stake of vibro-replacement stone.
Fig. 2 is the long and short stake system of vibro-replacement stone stake schematic diagram.
Viscous soil horizon 1, fine sand layer 2, fine sand layer 3, granular cushion 4, the long stake 5 of vibro-replacement stone, vibro-replacement stone stub 6, square 7.
The specific embodiment:
a kind of vibro-replacement stone is long, the ground arrangement of stub, the bottom, basis is divided into three layers of soil layer, be respectively viscous soil horizon 1 from top to bottom, fine sand layer 2 and fine sand layer 3, viscous soil horizon 1 top is equipped with granular cushion 4, it comprises the long stake 5 of vibro-replacement stone and vibro-replacement stone stub 6, the long stake 5 of vibro-replacement stone is along horizontal and vertical equidistant distribution, the line of centres of the long stake 5 of every adjacent four vibro-replacement stones consists of square 7, the center of each square 7 is provided with a vibro-replacement stone stub 6, the pile crown of the long stake 5 of vibro-replacement stone and the pile crown of vibro-replacement stone stub 6 all pass granular cushion 4, and the pile crown of the long stake 5 of vibro-replacement stone and the pile crown of vibro-replacement stone stub 6 are on same level, the other end of the long stake 5 of vibro-replacement stone extends to fine sand layer 3, the other end of vibro-replacement stone stub 6 extends to fine sand layer 2.

Claims (2)

1. a vibro-replacement stone is long, the ground arrangement of stub, the bottom, basis is divided into three layers of soil layer, be respectively viscous soil horizon from top to bottom, fine sand layer and fine sand layer, described viscous soil horizon top is equipped with granular cushion, it is characterized in that, it comprises long stake and stub, described long stake is along horizontal and vertical equidistant distribution, the line of centres of every adjacent four described long stakes consists of square, each described foursquare center is provided with a described stub, the pile crown of described long stake and the pile crown of described stub all pass described granular cushion, and the pile crown of described long stake and the pile crown of described stub are on same level, the other end of described long stake extends to described fine sand layer, the other end of described stub extends to described fine sand layer.
