Concrete tree stump for river bank protection

Abstract

A concrete tree stump for a river bank protection comprises a concrete pile and an inserting plate pile, the concrete pile comprises an inserting end and a pile head end, inserting grooves are symmetrically formed in the peripheral face of the concrete pile, the cross section of each inserting groove is in a C shape, the inserting plate pile comprises a body and connecting arms symmetrically arranged on the two sides of the body, the connecting arms are provided with inserting column parts matched with the inserting grooves in outline, and the inserting column parts are connected with the inserting ends. A margin gap is formed between an opening of the inserting groove and the connecting arm and can radially deflect around the inserting column part, and inserting plate piles are inserted between the adjacent concrete piles to be connected with each other. Compared with a traditional structure that two wood-like concrete piles are tightly connected together, the revetment structure formed through alternate connection of the concrete piles and the inserting plate piles has the advantages that structural gaps are eliminated, and the situation that soil on the bank is lost due to water flow scouring is effectively avoided. And the cross section shapes of the inserting grooves and the inserting columns can rotate by a certain angle to be matched, as shown in the figure 4 of the specification, deflection of a certain angle can be formed, and therefore the angle of the bank protection structure can be adjusted according to the river bank line.
