(1) Construction layout. Determine the position of the control bracket based on the cross-sectional location of the isolation facilities in the design documents, actual terrain and ground conditions, carry out necessary site cleaning, determine the centerline of the bracket, measure the accurate position of the bracket, and make markings.

(2) Measure the elevation of each column foundation to ensure a smooth and aesthetically pleasing top surface of the snake shaped knife mesh after installation. Set up a stepped section and measure the height of the steps to determine the height of the column.

(3) The installation of the bracket should be carried out in sections: first install the brackets at both ends, and then lay the middle column with a cable. The plane projection of the control bracket and the middle bracket should be in a straight line, and there should be no unevenness.

(4) The fixing method of the bracket on the wall is generally to fix it with expansion screws on the chassis. After fixation, the installation of the snake belly shaped knife net can be carried out.

(5) After installing the bracket column, first fix the wire drawing that needs to be used to install the blade barbed wire, and then use the support force of the wire drawing to install the blade barbed wire, and fix it with special buckles and calipers.
