Abstract

And the acquisition relates to road construction, in particular, to the construction of collapsible gauge coatings on weak soils. In order to increase the bearing capacity in the coating in the inter-cavity space and on the outside of both co-conductors, plates of various shapes were additionally laid at the junction of the plates forming them. Each additional plate is made with a symmetrical reduction of the cross section with respect to the joint. 5 il. 00 O5 oo vj O5 00

The invention relates to road congregation, in particular, to the construction of collapsible coatings on weak peat bases.

The purpose of the invention is to reduce the ability of the coating.

FIG. 1 shows the rutting with additional plates of triangular and diamond-shaped forms; on ig. 2 - the same, with stepped additional plates; in fig. 3 - A and A treatment in FIG. one; in fig. 4 - cover with solid additional plates; in fig. 5 is a section b-b and FIG. four..

The coating consists of supporting rectangular 1 slabs (gauges), as well as additional triangular 2 or diamond-shaped 3, or one-sided stepped 4, or double-sided stepped 5 plates of intercolumn 6 and outward 7 rows, laid on transverse elements 8 and in the places of its contact with the transverse elements 8 combined with their connections 9. When the additional plates can be made of a constant cross section over the entire length of the track, the bearing plates of the coating are combined with each other by connections 11.

The use of some form or configuration of additional plates in the coating is determined by the bearing capacity of the base soil, the availability of material for manufacturing or elements of great length, and their sizes are selected taking into account the exclusion of the maximum sediment at the junction of the non-gauge slab plates. The difference in performance of additional plates in cross section and the location of their larger cross section at the junction of the bearing plates of the gauge, as well as the symmetry of additional plates relative to the center of the junction of the bearing plates are caused by the need for uniform transfer of the mobile load to the weak base when it is displaced from the center to the edges of the carrier.

The triangular, diamond-shaped or stepped form of additional plates makes it possible to use longitudinal or transverse elements of different lengths for their assembly. In addition, the plates can be monolithic and rectangular.

Wood, metal, synthetics or other known materials can be used as material for the manufacture of additional plates or their elements.

The proposed construction of additional plates has a larger perimeter, in contrast to rectangular plates with the same area, which increases the carrying capacity.

The additional slabs are attached to the transverse elements, just like the joining of the slabs of the ruts with each other is carried out by any known method and by means of available materials.

When assembling the coating, pre-lay the transverse elements 8, on which two to four plates of 1 gauge are laid, and then two to four additional (non-bearing) plates of the inter-track 6 and the outer 7 rows. After that, additional plates are connected by links 9 with transverse elements, and plates 1 are ruts (carriers) also between each other by links 11. Plates 1, directly perceived the load during operation of the coating, transfer it to transverse elements 8 and then to base soil. After the plates 1 are seated on the base, this load is transmitted through links 9 to additional plates that restrain the overall draft of the coating. Moreover, the width of the additional plates at the junction of the two load-bearing 1 plates makes it possible to significantly reduce the overall draft of the coating in its most vulnerable place.
