Steel Framing Prefabricated Design

The Starting Frame is also called the Shield Launching Frame, which belongs to the auxiliary structure of the shield.
When the shield starts to excavate, the shield launch frame is used as the support carrier of the shield machine to bear the weight of the shield machine. The Shield Starting Base Structure is used in conjunction with the reaction frame.

Starting Base Frame is formed by splicing several groups of launching frame units with the same structure. Each group of launching frame units includes a base part, a supporting part, and a track platform part. The track platform part is symmetrically arranged at both ends of the base part and is connected to each other through the supporting part. The Starting Base Frame part is connected as an integral structure, and the track platform part is composed of a pipe section sliding track platform and an annular top iron sliding track platform arranged in parallel to each other, and correspondingly arranged on the pipe section sliding track platform and the annular top iron sliding track platform There are pipe section sliding track and annular top iron sliding track. The utility model adopts the detachable assembly structure design of multiple launching frame units, which is convenient for transportation and convenient and fast on-site assembly, which can meet the requirements of different use environments. Moreover, through the installation of a rail platform for sliding pipe joints and ring top irons, It can cooperate with the corresponding professional equipment in the construction process to meet the technological requirements of tunnel construction and improve the efficiency of construction.
