Embodiment 1

[0035] Example 1: Combining Figure 1 to Figure 8 Illustrate that the split integrated underground passage steel formwork trolley of the present invention is used to install the formwork group for pouring underground passage concrete, such as figure 1 As shown, the steel formwork trolley of this embodiment includes three frame-type formwork support devices arranged in sequence along the cross-section of the underground passage, from right to left are frame-type formwork support device one 100, frame-type formwork support device two 200 and Frame type formwork support device 3 300, the three frame type formwork support devices 100, 200, 300 are connected as a whole through several detachable box-shaped beams 20 arranged horizontally, and the frame type formwork support device 100 and frame formwork support The bottom of the third device 300 is equipped with a traveling mechanism, which can drive the frame formwork supporting devices 100, 200, 300 to move along a pair of longitu...

Embodiment 2

[0045] Embodiment 2: Combination Figure 8 to Figure 10 , and refer to Figure 1 to Figure 7 Illustrate the construction method of the split-integrated underpass steel formwork trolley of the present invention, and the specific steps are as follows:

[0046] Step 1: Install the formwork group on the steel formwork trolley, and arrange three frame-type formwork support devices 100, 200, 300 in sequence along the cross-section of the underground passage 50, and the three frame-type formwork support devices 100, 200, 300 reach the specified After the working position, its vertical position is connected up and down by detachable box-shaped beams 20, and it is stably and firmly located in the underground passage 50. The frame formwork support devices 100, 200, 300 are adjusted by vertical hydraulic cylinders 105, 205, 305 After reaching the standard height, remove the roof formwork support devices 400, 500 after bolting between two adjacent frame formwork support devices 100, 200,...

Embodiment 3

[0051] Example Three: Combining Figure 11 , and see Figure 1 to Figure 10 Illustrate the construction method of the split-integrated underpass steel formwork trolley of the present invention. The difference from the second embodiment is that the present embodiment is a pouring construction operation under the condition that the underpass 50 has some curved arc sections, such as Figure 11 As shown, when there is a curved arc section with a radius R of 400m in the underground passage, the steel formwork trolley is decomposed into a steel formwork trolley unit 1 with a length L of 12.5m, and the box-shaped beam on the steel formwork trolley 20 dismantling, and directly connect the three frame-type formwork support devices 100, 200, 300 bolts into a whole, so that the width of the steel formwork trolley is narrowed, and it is convenient to move forward along the arc section of the curve in the underground passage 50, because the steel formwork The trolley is shortened, so that...

Abstract

The invention discloses a slit integrated underground passage steel mold plate trolley and a construction method thereof, relates to the technical field of underground passage building concrete construction, and aims at the problems that the existing underground passage construction equipment is large in occupied area, the construction method is long in curing time, and continuous pouring construction cannot be realized. The steel mold plate trolley comprises at least three frame-type mold plate supporting devices which are connected integrally through detachable box-shaped cross beams, and at least two groups of posterior disassembly top mold plate supporting devices; a traveling mechanism at the lower part of the steel mold plate trolley can drive the frame-type mold plate supporting devices to move along longitudinal tracks; the two frame-type mold plate supporting devices positioned on the outer side can move in the horizontal direction under the operational control of a horizontal hydraulic oil cylinder group; each frame-type mold plate supporting device can lift in the vertical direction under the operational control of a vertical hydraulic oil cylinder group which is mounted on the corresponding frame-type mold plate supporting device; the at least two groups of posterior disassembly top mold plate supporting devices are respectively connected between the two adjacent frame-type mold plate supporting devices by bolts; universal wheels used for travelling are mounted at the bottom parts of the posterior disassembly top mold plate supporting devices.

Description

technical field [0001] The invention relates to the technical field of construction concrete construction of underground passages, in particular to a split-integrated steel formwork trolley for underground passages combined with early formwork removal technology and a construction method thereof. Background technique [0002] With the rapid development of urban construction, ground traffic congestion is increasing, and the development of underground passages is one of the effective ways to solve ground road congestion. In order to reduce the construction cost of the underground passage, some underground passages are constructed by open cut. The entire underground passage is divided into several construction units of a certain length, and the construction is gradually promoted to reduce the occupation time of the construction site and avoid hindering ground traffic. [0003] At present, the construction equipment used is a system that combines an integral formwork trolley and...
