Description

[0002] A gravity retaining wall uses its own gravity to maintain the stability of the retaining wall under soil pressure. It is a commonly used type of retaining wall in my country. Gravity retaining walls can be built with stone or concrete, and are generally made into a simple trapezoid.

[0003] Gravity retaining walls are retaining walls that rely on their own weight to resist the lateral pressure of the soil. Gravity retaining walls can be made of blocks, slabs, or precast concrete blocks, or cast in one piece using slab concrete or concrete. Semi-gravity retaining walls can be cast using concrete or less reinforced concrete. Gravity retaining walls can be built with stone or concrete, and are generally made into a simple trapezoid.

[0004] However, after supporting for a long time, gravity retaining walls are prone to insufficient tensile strength and safety accidents such as local collapse and deformation. For these retaining walls with safety hazards, the conventional method is to demolish them and rebuild them, but demolishing these retaining walls with hidden dangers is time-consuming and labor-intensive, and there are also major safety issues during the demolition of some gravity retaining walls that are very close to buildings.

During the pouring process, since the tensile device 3 is hollow in design, the concrete will be poured into the interior of the tensile device 3 during the concrete pouring process, so the push-pull block 37 is poured as one piece, and the first tensile plate 33 and the second tensile plate 34 are also fixed, and the tensile effect is always maintained. At the same time, since the transversely inserted first steel bar 4 and the obliquely inserted second steel bar 5 are connected by a connecting rod, an oblique support force is given to the retaining wall, and the connection between the first steel bar 4 and the second steel bar 5 further enhances the support effect and the overall tensile effect.

[0023] The reinforcement structure of this gravity retaining wall includes a retaining wall body 1, and the side walls and bottom of the retaining wall are provided with a plurality of tensile devices 3 that penetrate the retaining wall body 1 and are inserted into the soil layer 2. The retaining wall body 1 is provided with a plurality of first steel bars 4, and the steel bars are inserted into the soil layer 2. The retaining wall body 1 is provided with a plurality of second steel bars 5 that are obliquely inserted downward into the bottom soil layer 2.

[0025] As an improved specific implementation method, the tensile device 3 includes a hollow sleeve 36 and a hollow plug 30, the hollow plug 30 is fixed at the front end of the hollow sleeve 36, the upper end and the lower end of the hollow plug 30 are respectively provided with a first sliding groove 31 and a second sliding groove 35, the first sliding groove 31 and the second sliding groove 35 are both provided with a first tensile plate 33 and a second tensile plate 34, the first tensile plate 33 and the second tensile plate 34 are hinged to each other, the side ends of the first tensile plate 33 and the second tensile plate 34 are both provided with a sliding block 32, the sliding block 32 slides in the sliding groove, the hollow sleeve 36 is provided with an expansion component, the expansion component drives the first tensile plate 33 and the second tensile plate 34 to expand outward to form a triangular support portion, the expansion component includes A hollow push-pull block 37, wherein a first hinge block 371 is provided at the front end of the hollow push-pull block 37, a first connecting rod 311 and a second connecting rod 351 are hinged on the first hinge block 371, a second hinge block 310 is provided at the intersection of the first tensile plate 33 and the second tensile plate 34 in the first sliding groove 31, a third hinge block 350 is provided at the intersection of the first tensile plate 33 and the second tensile plate 34 in the second sliding groove 35, the first connecting rod 311 is hinged to the second hinge block 310, the second connecting rod 351 is hinged to the third hinge block 350, and when the hollow push-pull block 37 is pushed to the bottom of the sleeve, the first tensile plate 33 and the second tensile plate 34 are driven to extend outward through the first connecting rod 311 and the second connecting rod 351 to form a triangular support.

[0026] The pushing block pushes inward and drives the first connecting rod 311 and the second connecting rod 351 to be squeezed outward, thereby driving the first tensile plate 33 and the second tensile plate 34 to expand outward. When the push-pull plate is pushed to the bottom, that is, the first connecting rod 311 and the second connecting rod 351 are in a straight line, the push-pull plate can no longer be pushed down, and the first tensile plate 33 and the second tensile plate 34 form a triangular shape.
