Embodiment 1

[0036] Combine below Figure 1 to Figure 5 Describe in detail the construction method of the clutch type formwork trolley, trolley assembly and underground passage concrete of the present invention.

[0037] Such as figure 1 As shown, a clutch-type formwork trolley is used for concrete pouring construction of underground passages, including a top formwork trolley 31, a side formwork trolley 10 and a vertical support bar 20, and the side formwork trolleys 10 are distributed on both sides of the top formwork trolley 31 and The wooden formwork 14 is connected with the top formwork trolley 31; the bottom of the side formwork 10 is provided with a moving guide rail 11, and the moving guide rail 11 cooperates with the moving pulley 21 arranged on the vertical support bar 20 to drive the side formwork 10 to move longitudinally.

[0038]The top formwork trolley 31 comprises at least two top formwork trolley units arranged side by side and connected by a detachable type, each top form...

Embodiment 3

[0046] Continue to combine below Figure 1 to Figure 5 Describe in detail the concrete construction method for the underpass. The concrete construction method of the underground passage divides the underground passage into several construction sections for continuous construction, including the following steps:

[0047] S001: Lay the bottom plate 40 of the underground passage, and place the trolley assembly on the bottom plate 40. The two trolley components are the top formwork trolley 1 and the top formwork trolley 2, so that the top formwork trolley 1 is located in the first construction section. Top formwork trolley 2 is located in the second construction section;

[0048] S002: Please continue to refer to figure 2 , pouring concrete in the first construction section to form the structural side walls and structural roof of the first construction section at one time;

[0049] S003: Please continue to refer to figure 1 , after the concrete strength of the structural side...

Abstract

The invention discloses a clutch type formwork trolley, a trolley assembly and an underground passage concrete construction method, and belongs to the technical field of tunnel building concrete construction equipment. The formwork trolley comprises a top formwork trolley and side formworks, wherein the side formworks are distributed at the two sides of the top formwork trolley; a moving guide rail is arranged at the bottom of each side formwork; and each moving guide rail is matched with moving pulleys arranged at the lower end of the top formwork trolley to drive the corresponding side formwork to longitudinally move. The formwork trolley assembly comprises two top formwork trolleys coaxially arranged in the longitudinal direction of an underground passage and a set of side formworks, wherein the moving pulleys arranged at the lower ends of the two top formwork trolleys are in mutual butt joint, so that the side formworks longitudinally slide on the formwork trolley assembly. The construction method comprises the following steps of: firstly installing the formwork trolley assembly in place; then, performing concrete casting of a first construction section; next, performing demoulding on the side formworks, and moving the side formworks on the top formwork trolleys of the second construction section to be installed; then, casting the second construction step; and circulating the operations in such a way until the concrete construction of the whole underground passage is completed.

Description

technical field [0001] The invention belongs to the technical field of concrete construction equipment for tunnel construction, and in particular relates to a clutch-type formwork trolley, a trolley component and an underground passage concrete construction method. Background technique [0002] At present, with the rapid development of large cities, the space of ground roads is getting smaller and smaller, and the development of underground passages is one of the effective ways to solve the congestion of ground roads. When carrying out the construction of the underground passage, it is necessary to carry out the segmented pouring construction of the entire underground passage to reduce the time occupied by the construction site and to reduce the hindrance to the ground traffic. The formwork trolley is a large-scale steel structure formwork system widely used in the construction of tunnels such as roads, railways, hydropower, and urban railways. The formwork of the formwork ...
