Problems solved by technology

[0004] For projects with high construction period requirements, long lining length of tunnel one-way working face, or lagging construction progress in the early stage, and high pressure in the later stage, it can only be accelerated by compressing the process time (such as pouring speed, plug formwork installation time, formwork removal time, etc.), Construction quality is not easy to guarantee

Embodiment Construction

[0020] The double-trolley continuous pouring method for reinforced concrete lining tunnels provided by the present invention is equipped with two side arch lining trolleys and one pump truck 11 in the single working surface tunnel, and each side arch lining trolley A side arch maintenance trolley is arranged at the rear of the front arch lining trolley, and the side arch maintenance trolley of the front arch lining trolley is located between the front arch lining trolley and the rear crown lining trolley;

[0021] Before the continuous pouring construction of double-trolley lining with single working face, the binding of steel bars for the side arches of the first five warehouses starting from the side arch 2 of the lined section should be completed in advance, and the steel bars for the bottom plate of the eight warehouses starting from the side arch 2 of the lined section should be completed in advance. Ann and concrete pouring.

[0022] Then, starting from the third warehou...

Abstract

The invention provides a method for single working face double-trolley lining continuous casting of a reinforced concrete lining tunnel. Two side top arch lining trolleys and a pump truck on a singleworking face tunnel, the rear of each side top arch lining trolley is provided with a side top arch maintenance trolley, and the side top arch maintenance trolley of the front side top arch lining trolley is between the front side top arch lining trolley and the rear side top arch lining trolley; the front side top arch lining trolley sequentially performs side top arch lining work of odd number bins from a third bin each time an odd number bin is met with, and the side top arch lining work for each bin starts from the front and rear plug installation work of the side top arch lining of the bin; the rear side top arch lining trolley finishes the side top arch lining work of the first bin, and subsequently, side top arch lining work of even number bins is completed; the pouring sequence isas follows: odd number side top arch lining pouring by the front side top arch lining trolley, base plate pouring, even number side top arch lining pouring by the rear side top arch lining trolley andbase plate pouring; and circulation is performed in this way. The method can improve efficiency, reduce disturbance of each process and shorten lining construction period.

Description

technical field [0001] The invention relates to a continuous pouring technology for double-trolley lining of reinforced concrete lining tunnels with a single working face, which is suitable for reinforced concrete lining construction of tunnels in highways, railways, water conservancy, hydropower and other industries. Background technique [0002] Hydraulic lining steel formwork trolley is a relatively common equipment in tunnel secondary lining construction at present. This kind of lining trolley is designed as an integral steel formwork, driven by electric or oil cylinder, and poured by pumping concrete. Usually, for tunnels with small sections, due to the narrow construction space of the tunnel working face, the bottom of the steel formwork trolley cannot guarantee the passage of vehicles during the lining pouring process, and the tunnel lining is usually poured with a single trolley. [0003] The above conventional practice mainly has the following problems: [0004] Fo...
