Embodiment 1

[0061] Such as Figure 13-16 As shown, a construction method of trestle-type full-section inverted arch two-lined trolley equipment includes the following construction steps:

[0062] In the first step, the inverted arch formwork trolley 2 on the self-propelled trestle 1 passes through the inverted arch formwork 3 to complete the pouring and molding of the tunnel bottom, and then drives the inverted arch formwork 3 to move to the next section for construction; the second lining trolley 4 is On the self-propelled trestle 1, move to the inverted arch formwork trolley 2 to carry out the pouring construction of the tunnel top surface through the second lining formwork in a completed work area; The car frame is suspended above the self-propelled trestle 1;

[0063] In the second step, the second lining trolley 4 completes the pouring and molding of the top surface of the tunnel, and the inverted arch formwork trolley 2 completes the pouring and molding of the bottom of the next se...

Embodiment 2

[0068] Such as Figure 13 , 14 , 15, 17, and 16, a construction method for trestle-type full-section inverted arch two-lined trolley equipment includes the following construction steps:

[0069] In the first step, the inverted arch formwork trolley 2 on the self-propelled trestle 1 passes through the inverted arch formwork 3 to complete the pouring and molding of the tunnel bottom, and then drives the inverted arch formwork 3 to move to the next section for construction; the second lining trolley 4 is On the self-propelled trestle 1, move to the inverted arch formwork trolley 2 to carry out the pouring construction of the tunnel top surface through the second lining formwork in a completed work area; The car frame is suspended above the self-propelled trestle 1;

[0070] In the second step, the second lining trolley 4 completes the pouring and molding of the top surface of the tunnel, and the inverted arch formwork trolley 2 completes the pouring and molding of the bottom of...

Abstract

The invention discloses trestle-type full-section inverted arch secondary-lining trolley equipment and a construction method thereof. The trestle-type full-section inverted arch secondary-lining trolley equipment comprises a self-propelled trestle; rail ways are arranged on the self-propelled trestle; an inverted arch mould plate trolley and a secondary-lining trolley which do not interfere with each other in movement are arranged on the rail ways; the lower end of the inverted arch mould plate trolley is lifted with an inverted arch mould plate used for pouring the bottom surface of a tunnel;a secondary lining mould plate used for pouring the top surface of the tunnel is arranged above the secondary-lining trolley; the overall secondary-lining trolley is of an inverted U-shaped structure; the secondary-lining mould plate is formed by hinging a top mould to the side moulds on the two sides of the top mould; the top mould is arranged at the top end of the secondary-lining trolley; theside moulds are hinged to the two sides of the secondary-lining trolley through side mould oil cylinders; lifting posts which can lift up and down are arranged on the two sides of the secondary-liningtrolley; and moving wheels are arranged at the lower ends of the lifting posts. According to the trestle-type full-section inverted arch secondary-lining trolley equipment and the construction methodthereof, the bottom surface and the top surface of the tunnel can be poured and constructed simultaneously; the excavation of the tunnel is not affected in a construction process; moreover, the passage of a construction equipment vehicle in the tunnel is not affected; and the construction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction and underground engineering, and specifically relates to trestle-type full-section inverted arch two-lined trolley equipment and a construction method thereof. Background technique [0002] With the rapid development of my country's infrastructure construction, the requirements for tunnel construction are getting higher and higher. In the construction of some tunnels, the requirements for the rapid ring formation of the second lining of the inverted arch and the arc shape of the section are getting higher and higher. At present, the promotion of self-propelled trestles has combined the pouring of the inverted arches under the trestles relatively well, and the trestles can carry the rapid movement, positioning and reinforcement of the integral inverted arch formwork. However, due to the need for the layout of the waterproof board and the construction area arrangement of the secondary li...
