Through connecting and making fossil fragments and the support frame that corresponds firmly combine, adopt the installation and the dismantlement of the fossil fragments of being convenient for of the connection mode of dismantling. The detachable connection between the keel and the support frame can adopt a connection form that the keel is tightly bound on the support frame by a steel wire or a bolt and a nut are adopted to connect the keel and the support frame.
In one embodiment, the pedal is composed of a plurality of pedal units arranged closely.
In a preferred scheme, the support frame comprises a support cross rod, a support vertical rod and an inclined strut, the upper end of the support vertical rod is connected with the outer end of the support cross rod, the inclined strut is gradually inclined inwards from bottom to top, the lower end of the inclined strut is connected with the lower end of the support vertical rod, and the upper end of the inclined strut is connected with the inner end of the support cross rod. The supporting upright stanchion is used for connecting with the water stop bolt; the support cross bar is used for detachable connection with the keel. By adopting the structure, the supporting cross rods, the supporting vertical rods and the inclined supporting rods form a triangular supporting structure so as to enhance the bearing capacity of the open caisson construction operation platform, ensure the structure to be firm and ensure the safety.
The keel and the pedal plate can be made of wood materials. The support frame can be made of steel section bars, and the cross section of the steel section bars can be T-shaped, L-shaped or other shapes.
In the preferred scheme, the open caisson construction operation platform further comprises a guardrail, the guardrail is arranged on the inner side of the pedal plate, and the lower end of the guardrail is connected with the support frame. The guardrail can be used for protecting operating personnel to avoid causing the accident of falling because of the accident situation, further ensure the security.
The inner part and the outer part are respectively as follows: the side close to the inner wall of the open caisson shaft is the outside, and the side far away from the inner wall of the open caisson shaft is the inside.
The utility model discloses an open caisson construction operation platform is simple structure not only, and the security is high, installs and removes the convenience moreover, and repeated cycle uses is favorable to improving the efficiency of construction and reduces installation cost.
