SU1217978A1 - Arrangement for protecting embankments from water erosion - Google Patents

Description

The invention relates to regulatory structures, protecting all railways, highways, rivers, reservoirs.

The purpose of the invention is to improve the operational reliability of embankments,

FIG. 1 shows the device, section A-A in FIG. 2; in fig. 2 shows a section BB in FIG. one.

The device includes reinforced concrete sections 1 installed with the ability to move to the bottom of the channel in the slots of the posts-guides 2, sunk to the line of possible depth of softening 3 and interconnected from the water area above the surface of the water by transverse straightening 4.

The device is secured on the side of the back lash through a system of anchors 5, rigidly connected to each other and with anchor plates 6, laid into the array of filling to one third of its height and joined together by 1 cross bar pin 7 on the fixtures of embedded parts jellies reinforced concrete slabs or welded grooves in metal structures.

The installation of the device is carried out with a preliminary development of the excavation for laying the system of anchors, subsequent submersion of the posts-nap5 into the ground using pile-building equipment and installation of the posts-guides of reinforced concrete sections into the grooves. Anchors before laying are coated with anti-corrosive material10. After they have been mounted, a cobblestone or a stone draft will be fixed to the top of the racks, directed to the wall.

When the bottom of the channel is eroded, the reinforced concrete sections under their own weight will be lowered into the erosion of the erosion, and in their place new sections will be installed in the grooves of the racks facing the ux. According to the position of the upper sections, it will be possible to judge the magnitudes of the spacing of 20 units and on individual sections of the device. When eroding the bottom of the channel, the systems of anchors and struts provide a static equilibrium of the device, thereby excluding its spatial movement.

The use of the proposed device reduces the construction cost by 30% compared with the prototype.
