Novel implanted stiff skeleton pile plate retaining wall

Technical Field

The utility model relates to a retaining wall technical field specifically is a novel implanted strength nature skeleton pile sheet retaining wall.

Background

The retaining wall is a structure for supporting roadbed filling soil or hillside soil and preventing the filling soil or the soil from deforming and destabilizing, and the part of the cross section of the retaining wall, which is directly contacted with the supported soil, is called a wall back; the part facing the wall back and being empty is called the wall surface; the part directly contacting with the foundation is called a substrate; the top surface of the wall opposite the base is called the wall top; the front end of the base is called a wall toe; the rear end of the base is called a butt.

Under the construction condition of steep slope topography or river along, the construction of conventional pile slab barricade machinery pore-forming method is difficult, it is great to adopt artifical hole digging method risk, and the geological conditions that the stake is located is better again, rock unipolar saturated compressive strength is generally not less than 30MPa, the intensity that basically adopts than the concrete of stake is still higher, and the foundation of stake department is stable, there is not the unfavorable structural plane of extroversion, if dig the complete and rock mass that intensity is high, the lower concrete of relative strength of reinjection, it is high not yet original rock foundation integrality and intensity, and because rock strength is high, construction period is also longer.

SUMMERY OF THE UTILITY MODEL

The not enough to prior art, the utility model provides a novel implanted strength nature skeleton pile slab retaining wall, the engineering cost who has practiced thrift the pile foundation below the ground part, practice thrift the time limit for a project advantage, solved under the construction conditions in abrupt slope topography or river, conventional pile slab barricade machinery pore-forming method construction difficulty, it is great to adopt artifical hole digging method risk, and the geological conditions that the stake was located is better again, rock unipolar saturated compressive strength is generally not less than 30MPa, basically still is higher than the intensity of the concrete that the stake adopted, and the ground stability of stake place department, there is not the unfavorable structural plane of camber, if dig the complete and high rock mass of intensity, the lower concrete of relative strength of reperfusion, original rock foundation and intensity are high yet, and because rock strength is high, the also longer problem of construction period.

The utility model provides a following technical scheme: the utility model provides a novel implanted stiff skeleton pile slab retaining wall, includes ground and fill layer, the ground is located the inside anchor of fill layer right side below and goes into stiff skeleton anchor section, the top of stiff skeleton anchor section extends to the outside of ground and forms stiff skeleton pouring pile body through concrete placement, be equipped with retaining plate between the adjacent stiff skeleton pouring pile body, the inboard that retaining plate is close to the fill is equipped with the stock.

Preferably, pile holes for anchoring the stiff framework anchoring sections are vertically formed in the foundation.

Preferably, one side of the soil retaining plate close to the filling layer is provided with an anchor rod hole for anchoring an anchor rod.

Preferably, the anchor rod penetrates through the filling layer and is anchored into the foundation, and the anchor rod and the horizontal plane form a certain inclination angle.

Compared with the prior art, the utility model discloses possess following beneficial effect:

the novel implanted stiff skeleton pile plate retaining wall fully utilizes the integrity and strength of the existing rock mass, ordinary piles above the ground are anchored into a rock foundation through the implanted stiff skeleton pile, the engineering cost of the part below the ground of a pile foundation is saved, the construction method can finish drilling construction by adopting a small-sized drilling machine, the problem that large machinery cannot be constructed under the steep slope terrain condition is solved, manual underground hole digging operation is not needed, the construction risk is reduced, the construction method also greatly reduces the engineering cost of the underground part of the pile foundation, and the construction period is saved.
