Abstract

The invention relates to the technical field of tunnel construction, in particular to a trestle with a postpositive drive and a method of installing and adjusting. The trestle with the postpositive drive includes a main bridge which is arranged on a support surface, and the included angle between the bridge face of the main bridge and the support surface is sharp. The front and rear ends of the main bridge are correspondingly connected with a front approach bridge and a rear approach bridge. The front approach bridge includes an inclined section and a horizontal section, and the included anglebetween the bridge face of the inclined section and a horizontal face is sharp. The horizontal section is connected with the main bridge, and the length of the front approach bridge is longer than the length of the main bridge. The overall structural form of the existing trestle is changed, the length of the front approach bridge is greatly increased, and the length of the rear approach bridge isshortened. Therefore the construction area scope of paving an inverted arch template and pouring concrete is enlarged, the construction space is become spaciously, and the construction efficiency isfurther improved by ensuring that a construction vehicle can pass through the trestle smoothly and safely.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a driving rear trestle and an installation and adjustment method. Background technique [0002] During tunnel construction, when the front of the tunnel is excavated, the stones produced need to be transported out through the rear, followed by construction and filling of concrete. During the construction of the inverted arch to fill the concrete, the passage of the ballasting vehicle is blocked. At this time, it is necessary to use the trestle bridge to cross the inverted arch to fill the concrete construction area, so that the ballasting vehicle can pass through the trestle bridge, and at the same time, the engineers are working under the trestle bridge. [0003] There are many types of trestle bridges used in tunnel construction. The relatively simple trestle bridge is a structure spliced ​​by I-beams. Separation requires laying formwork separately, and the constru...
