Slab precast pavement


(57) Abstract:

The inventive slab precast pavement tabs, located at the adjacent faces of the plates, made in the form of a tooth formed on the base-side support surface of the plate. Curved anchoring element is formed trapezoidal in cross section and inclined from the center of the plate stacked sections different in terms of curvature. 3 C.p. f-crystals, 3 ill.

The invention relates to the construction, namely the construction of roads, airfields, foundations for various structures power transmission line supports, and other structures, working directly with the ground, mostly weak.

There are various road design [1,2], the disadvantages are their low bearing capacity, stability and efficiency.

Closest to the proposed technical solution [3], taken as a prototype.

The disadvantages of the prototype are increased intensity and complexity of the device, and low bearing capacity.

The purpose of the invention is the increase in the carrying capacity, sustainability and effectiveness.

The aim is achieved in that in the lower middle part of the arc of the adjacent faces of the plate. On a support surface of a plate made the tabs at the adjacent faces of the plate.

In Fig. 1 shows a slab of pavement in isometric, bottom view, and Fig. 2 is a wiring diagram of paving slabs in the plan, bottom view, and Fig. 3 - section A-a and B-B in Fig. 2.

Slab precast pavement constructed on soft soils, includes the base plate 1 and the curved anchoring element 2 (in the lower part of the plate 1) variable curvature, tilted from the center of the plate, with the tabs it beyond the contour of the base plate 1 and with the teeth 3 on the bottom face of the base plate 1 with the opposite projections of the frontal and the lateral surface of the base plate 1.

The proposed construction works as follows.

After appropriate paving slabs due to the arcuate anchoring elements 2 and teeth 3 provided the solidity of the connection of the pavement as a whole without displacement of the plates in the longitudinal and transverse directions and without exceeding them in front of each other, i.e., achieves the evenness of the coating due to the bearing plates on the protruding portion arcuate anchoring elements 2.

When exposed to active transport of loads on the floor across the plates is formed bowl progynova hard rock layers. As a result of bending of plates in the zone of the bowl deflections arcuate anchoring elements 2 at their lower end, remote from the bottom surface of the plate, move, and due to their inclined from the center plate location so affect the soil, in order to involve as much deeper and more durable its layers, resulting in an active shift effort is created and opposes the maximum reactive resistance of the soil, allowing you to work the design in the elastic stage, even on soft soils when exposed to the ground with force, much less a valid, permanent, independent of the load increase or decrease the bearing capacity of the soil, which increases the bearing capacity and stability of the proposed design significantly reduces its consumption and increase efficiency.

1. SLAB PRECAST pavement containing located on its base curved anchoring element, characterized in that, to improve the bearing capacity and stability of the coating on the soft ground, it is equipped with two located in the adjacent faces of the base-side support surface protrusions in the form of the tooth, and arcuate Anke is Noah in terms of curvature, the middle part of the arc of each of which stands for the contour of the base plate by a value not less than the thickness of the tooth located at the side of the slab opposite to the protruding middle part of the corresponding arc.

2. The plate p. 1, characterized in that the curvature of the arcuate sections of the anchor element is inversely proportional to the length of the end plate, along which it is located.

3. Plate PP.1 and 2, characterized in that the arcuate section anchor element connected with each other with formation of a C-shaped path, crossing the face of the base plate.

4. Plate PP.1 and 2, characterized in that the end section with the arc of the lesser curvature is located from the ends of the plate at a distance of not less than the height of the anchor element.
