SUMMERY OF THE UTILITY MODEL

The utility model provides a bracing formula double row pile to solve the not enough of prior art.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a double row of stake of bracing formula, includes front row pile group and back row pile group, front row pile group includes a plurality of front row piles, back row pile group includes a plurality of back row piles, be equipped with a plurality of sloping between every back row pile and the front row pile that corresponds, two adjacent sloping are the triangular distribution setting, and the both ends of every sloping are fixed with back row pile and front row pile respectively.

As a further description of the above technical solution: the number of the oblique beams is at least three.

As a further description of the above technical solution: the upper ends of a plurality of front row piles of the front row pile group are fixed on a crown beam.

As a further description of the above technical solution: the upper ends of a plurality of rear row piles of the rear row pile group are fixed on a crown beam.

As a further description of the above technical solution: the back row of piles is higher than the front row of piles, and the inclined beam positioned at the uppermost position inclines downwards from the back row of piles to the front row of piles.

The utility model discloses following beneficial effect has:

1. under the action of lateral pressure, the lateral pressure is transmitted to the oblique beam through the rear row of piles, the force is transmitted to the front row of piles by the oblique beam, the force is decomposed into horizontal force and vertical force by the transmission action of the oblique beam, the axial force of the front row of piles is increased due to the transmission of the vertical force, the bending moment on the oblique beam is reduced, the axial force is increased, and the compression resistance of the reinforced concrete is more fully exerted. The rear row of piles of the whole structure are pulled, the front row of piles are pressed, the oblique beams are pressed and pulled at intervals, and the members are cooperatively stressed, so that the material performance can be fully exerted;

2. compared with the portal-shaped and h-shaped double-row piles, the space between the inclined strut type double-row piles is triangular, the integral rigidity is higher, the lateral pressure born under the same condition is higher, and the displacement can be controlled more effectively;

3. the inclined beams on the inclined strut type double-row piles are more reasonable in internal force distribution compared with cross beams in a shape like a Chinese character 'men' and a shape like a 'h', the bending moment on the inclined beams is obviously reduced, the bending moment of front and rear row piles is also reduced, the section size and the reinforcing bars are more reasonable, and the economical efficiency is better;

4. the back row piles 1 and the front row piles 2 are connected by adopting the oblique beams, and the number and the inclination angle of the oblique beams 3 can be flexibly arranged according to the height of the side slope and the terrain condition, so that the structure stress is more reasonable, the structure stress is more coordinated with the surrounding environment, and the method is particularly suitable for the high backfill side slope management engineering of the mountain area under the complex condition.
