Steel trestle construction method and facility with percussion drill limiting pore-forming implantation and crawler crane combined
The invention discloses a steel trestle construction method and facility with percussion drill limiting pore-forming implantation and a crawler crane combined. The construction method comprises the steps that construction is carried out from one end of a steel trestle to the other end of the steel trestle one by one so that the complete trestle can be constructed, and the next span of cantilever beret piece beam is formed on the previous span of steel trestle which has already been constructed; a limiting rack and a percussion drill are fixed to the next span of cantilever beret piece beam through double-buckling H-steel and deformed steel bar U-shaped clamps, and accordingly the plane position of the overhung limiting rack is located at the plane position of the next span of steel pipe piles of the steel trestle; a steel casing is placed in the limiting rack, and a hammer of the percussion drill hammers bedrock in the steel casing so that pile holes can be formed. According to the steel trestle construction method and facility, under the construction conditions of heavy flow of water and oblique river bed rock surfaces, there is no need for operators to drill a trestle pipe pile foundation by blasting through underwater operation, overwater equipment such as a ship does not need to enter the scene, the potential safety risks of operation by the operators and the ship under the condition of heavy flow of water are avoided, engineering cost is lowered, and construction safety is improved.
