Large-span continuous steel truss multi-point synchronous automatic cyclic alternating sliding shoe push system and construction method thereof
The invention discloses a large-span continuous steel truss multi-point synchronous automatic cyclic alternating sliding shoe push system. The system comprises a steel truss assembling platform, push steel launching noses, temporary piers, slideways and a control system. The slideways comprise primary slideways and secondary slideways, and the primary slideways are provided with push sliding shoes capable of vertical height adjustment for installing reaction frames of continuous push jacks of push steel trusses on the front ends of the primary slideways; the two sides of each push sliding shoe are each provided with a push sliding shoe transverse jack, the continuous push jacks, the push sliding shoe transverse jacks and push sliding shoe vertical jacks form a push slip hydraulic jack system, each set of jacks are provided with a pressure sensor and a displacement sensor for detecting pressure of each jack, displacement of each hydraulic cylinder and concrete positions of the push sliding shoes; and control data of the hydro-electric control system on each slideway is fed back to a master control computer in a concentrated mode, and the computer emits control instructions to the hydro-electric control systems so as to realize push construction synchronization. The construction method is fast, safe and reliable.
