Abstract

The invention relates to the construction of pits and slopes and to their fastening. The goal is to increase the strength of fixing anchor rods in the ground. To do this, facing 1 is erected on the slope of a pit or mine wall and anchored in the ground by inserting anchor rods (C) 3 into it. material 4, leaving uninsulated end sections 5. C 3 is fixed in the soil by passing a direct current through them until the end of the process of electrochemical corrosion in areas 5. The direction of the current is periodically changed. As a result of the electrochemical decomposition of the material C 3 in the areas 5, the fixing zones 9 are formed. In soils with strong layers, in places of contact with them, C 3 leaves additional uninsulated areas. In this case, when current is passed through C 3, additional zones of fixation are formed at the points of contact of C 3 with layers of strong soils. 1 h. item f-ly, 2 ill. 7 ss (L o oo ace with to

Description

The invention relates to the construction, in particular to the anchoring of pits and slopes, and can also be used for the construction of anchor lining of mine workings.

The electrochemical decomposition of the material of the rods and the caching of them with the products of this decomposition leads to the formation of fastening zones 9 at the end. When the rods 3 are installed in soils that are well-proven, the purpose of the invention is to raise 5 solid layers 10 (Fig. 2) to leave further electrochemical decomposition of the material of the rods and zanking them with the products of this decomposition to form fixing zones 9 at the end. When installing rods 3 in soils having strong layers 10 (Fig. 2), additional

strength of fixing in the ground anchor rods.

FIG. 1 shows a scheme for anchoring the lining with fastening of the ends.

relatively uninsulated areas at the points of contact of the rods 3 with these layers. In this case, when DC is passed through the rods 3, it is fouled; in fig. 2 shows the anchor pattern at the places of their contact with layers of strong soils 10 additional fastening zones 11.

rod van in the areas of its contact with layers of strong soils.

The method is as follows.

On the slope of the pit or mine wall, a team or monolithic lining 1 is erected, in which openings 2 are provided for accommodating steel anchor rods 3, which are pre-coated with an insulating material 4 prior to introduction into the ground.

Claims (1)

1. The method of anchoring the lining in the ground, including the construction of the lining, the introduction of anchor rods into the ground, the connection of their outer ends with the lining (bituminous, rubber-bituminous or any other- and securing the rods by passing with mastic or rubber or plastic shells) leaving the non-insulated end sections 5. The outer ends of the rods 3 are connected to the lining 1 by means of threaded or welding them with direct current before the end of the electrochemical corrosion process, in order to increase the anchorage strength of anchor rods They are precoated with tokoozolnyh compounds 6. The rod 3 is secured with a fixed material, leaving the ground behind the prism 7 of the caving. For the etched end sections, pass through the rods 3 from the source 82. The method according to claim 1, wherein The direct current until the end of the process of the elec- tant is left additionally to non-insulated chemical corrosion. The direction of the tokens at the points of contact with the rod is periodically changed. Occurs with layers of strong soils. relatively uninsulated areas at the points of contact of the rods 3 with these layers. In this case, by passing direct current through the rods 3, in the places of their contact with the layers in the places of their contact with layers of strong soils 10, additional fastening zones 11 are formed. Invention Formula 1. The method of anchoring the lining in the ground, including the construction of the lining, the introduction of anchor rods into the ground, the connection of their outer ends with the lining through them a direct current until the end of the process of electrochemical corrosion, characterized in that, in order to increase the strength of fixing the anchor rods, they are precoated with tokoizol Fig. 2.
