Embodiment

[0018] refer to Figure 1 to Figure 3 , the present embodiment provides a second lining trolley for tunnel construction, comprising a second lining trolley body 1, the first rubber strip 2 and the second rubber strip 3 are respectively provided at the head and tail ends of the top of the second lining trolley body 1, and the second rubber strip 3 is provided respectively. The first rubber strip 2 and the second rubber strip 3 are bonded and fixed on the second lining trolley body 1 respectively along the designed arc at the top and bottom ends of the top of the second lining trolley body 1, and the first rubber strip 2 is a right triangle in cross section. The rubber strip, the second rubber strip 2 is a rubber strip with an isosceles triangle in cross section, and the height and waist length of the first rubber strip 2 and the second rubber strip 2 are the same, and the same waist length is the length of the first rubber strip 2. The hypotenuse of the cross section is the sam...

Abstract

The invention provides a secondary lining platform vehicle of tunnel construction and a using method thereof. The vehicle comprises a secondary lining platform vehicle body, both front and rear ends of the top of the secondary lining platform vehicle body are provided with a first rubber strip and a second rubber strip respectively, the first and second rubber strips are circularly fixed to the secondary lining platform vehicle body through designed radian at both front and rear ends of the top of the secondary lining platform vehicle body, the first rubber strip is a rubber strip with the cross section of a right angled triangle, the second rubber strip is a rubber strip with the cross section of a right angled triangle, and the heights and sides of the first and second rubber strips arethe same. The secondary lining platform vehicle of tunnel construction and the using method thereof are used for solving the problem that the safety of a high-speed train is threatened to a great extent by easy slag and block falling of existing high-speed railway tunnel construction seams, and the secondary lining platform vehicle of tunnel construction and the using method thereof belong to thetechnical field of high-speed railway tunnel construction.

Description

technical field [0001] The invention relates to a secondary lining trolley and a method for using the same, belonging to the field of high-speed railway tunnel construction. Background technique [0002] Today, with the vigorous development of national economic construction, high-speed railway has become an important driving force for economic development, and high-speed railway transportation has also become an important mode of transportation for national travel. Tunnel engineering is an indispensable part of high-speed railways. Due to the high air pressure generated when high-speed trains pass through tunnels, many linings have fallen off in recent years, which has brought extremely high risks to the safe operation of high-speed railways. Contents of the invention [0003] The object of the present invention is to provide a secondary lining trolley for tunnel construction and its use method, so as to solve the problem that slag and blocks are prone to occur at the cons...
