Mendeleevets- MG / Mendeleevets- MGB / Mendeleevets- FPG
deep silicon iron anodes

Application area

Deep groundbeds are used to be installed in boreholes in such places where the upper layers of the soil with the capacity more than 5 m have electrical resistivity more than 100 Ohm∙m and in areas with dense building or with limited access for anodic field.

Deep block groundbeds are used to be installed into boreholes in such areas where the upper layers of the soil with the capacity more than 5 m have electrical resistivity more than 100 Ohm∙m and in areas with dense building or with limited access for anodic field.

The block of the deep groundbed consists of two sections, both of them have two silicon iron electrodes interconnected electrically. So each groundbed block includes four electrodes.

Current distribution is provided through two connecting cables (one cable for each section). Connecting cables don’t have any discontinuities along the length and they are drawn outside to the surface to be attached to the anodic cable line. Connecting cables are set in the factory. The length of each cable is determined by the depth of installation in the borehole.

Transportation of the block is realized in the folded way (see photo above). While installation the sections unfold and take coaxial position (see illustration).

The design provided for connection of blocks into the chain, that allows to raise current loading and to reduce transitional resistance. Maximum quantity of the deep groundbed blocks which can be installed into one borehole is 4 pieces.

Gas that is formed while working of deep groundbed is drawn outside to the surface through the gas outlet tube. The gas outlet tube has perforation along all the height of the chain and is delivered for the the concrete order on the basis of one tube for one chain of groundbeds installed in the borehole. The length of the gas outlet tube is equal to the depth of the borehole.

The hollow space around the anode should be filled with a coke-mineral activator (KMA) produced by Chemservice in order to reduce spreading resistance of anodic current and to slow down anodic dissolution.

Deep block groundbeds Mendeleevets-MGB / Mendeleevets- FPG are worked out as an alternative to heavier and bigger deep groundbeds Mendeleevets-MG.

The construction of the block groundbed was noticeably remade and simplified in order to unify the installation works. And at the same time the working element of the groundbed (silicon iron electrode) remained the same.

Each block of the groundbed includes one section with the silicon iron electrode inside. Current distribution to the block of the groundbed is provided through the connecting cable.

The kind of deep ground, consisting of groundbeds Mendeleevets-MGB / Mendeleevets- FPG (quantity of blocks in a borehole, quantity of boreholes, distance between boreholes, etc.) is determined by the project of cathodic protection.

The design provided for connection of blocks into the chain. It allows to raise current loading and to reduce transitional resistance. Connection of blocks into the chain is realized when installing groundbeds into the borehole and consists in attachment of blocks to each other with the help of a holder. Maximum quantity of the deep groundbed blocks of Mendeleevets-MGB which can be installed into a borehole is 20 pieces.

Gas that is formed while working of deep groundbed is drawn outside to the surface through the gas outlet tube. The gas outlet tube has perforation along all the height of the chain and is delivered for the the concrete order on the basis of one tube for one chain of groundbeds installed in the borehole. The length of the gas outlet tube is equal to the depth of the borehole.
