technical field

The utility model relates to the technical field of retaining walls, in particular to a new type of implanted stiff skeleton pile plate retaining wall.

Background technique

Retaining wall refers to a structure that supports roadbed fill or hillside soil and prevents the fill or soil from being deformed and unstable. In the cross section of the retaining wall, the part that is in direct contact with the supported soil is called the wall back; and The part opposite to the back of the wall and facing the air is called the wall; the part that is in direct contact with the foundation is called the base; the top surface of the wall opposite to the base is called the top of the wall; the front end of the base is called the wall toe; the rear end of the base called the wall heel.

Under the construction conditions of steep slope terrain or along the river, it is difficult to construct the conventional pile-slab retaining wall mechanical hole forming method, and the manual hole digging method is more risky, and the geological conditions of the piles are good, and the uniaxial saturated compressive strength of the rock is average. It is not less than 30MPa, which is basically higher than the strength of the concrete used for the piles, and the foundation where the piles are located is stable, and there is no unfavorable structural surface cambered out. The lower concrete does not have the high integrity and strength of the original rock foundation, and because the rock strength is extremely high, the construction period is also longer.

Basically, the strength is higher than that of the concrete used for the piles, and the foundation where the piles are located is stable, and there is no unfavorable structural surface. , There is no problem of high integrity and strength of the original rock foundation, and due to the extremely high rock strength, the construction period is also long.

The utility model provides the following technical solutions: a new type of implanted stiff skeleton pile-plate retaining wall, comprising a foundation and a filling layer, wherein the foundation is located in the inner anchoring section of the stiff skeleton under the right side of the filling layer, The top of the rigid frame anchoring section extends to the outside of the foundation and forms a rigid frame pouring pile body through concrete pouring, and a soil retaining plate is arranged between the adjacent rigid frame pouring pile bodies, and the soil retaining plate An anchor rod is provided on the inner side near the filling.

Preferably, a pile hole for anchoring the rigid frame anchoring section is vertically opened on the foundation.

Preferably, the side of the earth retaining plate close to the filling layer is provided with a bolt hole for the bolt to be anchored in.

Preferably, the anchor rod penetrates the filling layer at a certain inclination angle to the horizontal plane and is anchored into the interior of the foundation.

Compared with the prior art, the utility model has the following beneficial effects:

The new type of implanted stiff skeleton pile-plate retaining wall makes full use of the integrity and strength of the existing rock mass, and anchors the ordinary piles above the ground into the rock foundation through the implanted stiff skeleton piles, saving the pile foundation ground. For the following part of the project cost, this construction method can complete the drilling construction with a small drilling rig, which solves the problem that large-scale machinery cannot be constructed under the conditions of steep slope terrain, and does not require manual underground digging operations, which reduces the construction risk. This construction method is also extremely The earth reduces the engineering cost of the lower part of the pile foundation and saves the construction period.
