Abstract

The invention discloses tunnel construction equipment, i.e., a movable trestle comprising a main bridge which is provided with an approach bridge and a support both in the front part and the rear part of the main bridge; the movable trestle is characterized by also comprising a hydraulic system and an electric system as well; both the front end and the rear end of the main bridge are provided with a walking unit; and the main bridge comprises a deformed Bailey truss, a bridge deck and a bridge deck supporting bracket. The invention has the advantages that the research and development of the movable trestle can not only facilitate the hauling-out of slag charge produced by excavation in the cave, but also ensure the normal construction of inverted concrete lining, thereby significantly improving efficiency, shortening construction period, ensuring a construction period and realizing civilized construction as well.

Description

(1) Technical field [0001] The invention relates to tunnel construction equipment, in particular to a mobile trestle. (2) Background technology [0002] At present, the capacity of my country's main railway lines is very tight and cannot meet the needs of passenger and cargo transportation. It is urgent to build dedicated passenger lines to meet the growing demand for intercity passenger transportation in densely populated cities with developed economies; in addition, for a long time, the layout of my country's railway network It has been showing an unreasonable situation, especially in the vast western region, where the transportation network is sparse, the transportation capacity is seriously insufficient, and the communication ability with the eastern and central regions is poor. Therefore, in order to meet the needs of passenger and cargo lines, improve the layout of the national railway network, and meet the needs of transportation, the country has vigorously carried out...
