The invention provides a component hoisting travelling foundation in a complex environment of a large railway station building. The foundation is a trestle structure formed by assembling upright units, cross beam units, inter-column supports and a ramp unit, and all upright units are assembled and connected into a frame roadbed through node boards; the ramp unit is arranged at the end of the frameroadbed; the cross beam units are arranged on the upright units; and roadbed boxes are arranged at the top of the cross beam units. A construction method of the component hoisting travelling foundation in the complex environment of the large railway station building is also provided. The method comprises the following steps that 1) a structure of each unit of a trestle is designed; 2) each assembling unit of the trestle is manufactured; 3) all upright units are assembled into a roadbed for a crawler crane to travel; 4) a slope ramp is arranged at the end part of the trestle; 5) a travelling position and a hoisting position, on the trestle, of the crawler crane are provided with measurement monitoring points; 6) hoisting construction is performed on the trestle; and 7) deformation of the trestle is monitored through the measurement monitoring points in the construction. The travelling roadbed structure is assembled freely according to the field construction environment.
Description
technical field [0001] The invention relates to the field of construction, in particular to a construction technology for a large-scale crawler crane traveling assembled trestle under the complex environmental conditions of a large-scale railway station building. Background technique [0002] In recent years, China's railways have developed rapidly, and large-scale railway station building projects have emerged one after another. The structure of the large railway station building is complex, the weight of the single steel structure is heavy, and the construction environment is complex, so that the large steel structure components cannot be directly installed in place. [0003] Due to the complex structure and large span of large railway station buildings, large steel structures are often used as the structural system. Due to the complex construction environment, large steel components cannot be directly installed in place. Therefore, it is necessary to build a trestle stru...
