Embodiment 1

[0048] Such as figure 1 as shown, figure 1 It is the front view of the formwork walking system of the immersed tube tunnel, a kind of walking system of the formwork of the immersed tube tunnel, including a rail 1 and a traveling trolley 2 arranged on the rail 1 and capable of walking along the rail 1, on which the trolley 2 is set There is a fixed frame 5, and the fixed frame 5 is used to install the inner formwork 7 and the inner formwork support 6, and the two ends of the fixed frame 5 are provided with a fixed frame lifting mechanism 502, and the fixed frame lifting mechanism 502 is used for stretching to pouring The foundation separates the fixed frame 5 from the trolley 2, wherein the structural relationship between the fixed frame 5, the inner formwork 7 and the inner formwork support 6 is shown in Figure 4 .

[0049] Such as figure 2 as shown, figure 2 is the side view of the formwork walking system of the immersed tube tunnel, figure 2 The connection relations...

Embodiment 2

[0076] An immersed tube tunnel formwork walking system, using the immersed tube tunnel formwork walking system as described in Embodiment 1, comprising an inner formwork support 6 with an inner formwork 7 arranged on the trolley 2, the inner formwork 7 includes a The first formwork and the second formwork of the overall formwork structure, the inner formwork support 6 includes a first support and a second support that can rotate relative to the first support, the first support is provided with the first formwork, the A second formwork is arranged on the second support, and a fixed frame elevating mechanism 502 is also arranged on the second support.

[0077] Wherein the concrete retractable structure of the inboard formwork support 6 with inboard formwork 7 sees Figure 4 .

[0078] Such as Figure 4 as shown, Figure 4 It is a schematic diagram of the connection relationship between the fixed frame 5, the inner formwork support 6 and the inner formwork 7, the inner formwor...

Embodiment 3

[0082] A method for implementing formwork walking of an immersed tube tunnel, using the formwork walking system of an immersed tube tunnel described in Embodiment 1, the steps are as follows:

[0083] Step 1, install the rail bracket 1022 to a predetermined position;

[0084] Step 2, install the track outrigger 1021 and the rail beam 101, and set the horizontal elevation;

[0085] Step 3, fixing the rail 103 on the rail beam 101, and setting the traveling trolley 2 on the rail 103;

[0086] Step 4: Set the fixed frame 5 on the trolley 2, and set the fixed frame elevating mechanism 502 at both ends of the fixed frame 5.

[0087] In step 1, the predetermined position is specifically the starting point of the formwork installation area 3 and the end point of the immersed tube pouring area 4, and a rail bracket 1022 can be optionally set between the starting point and the end point;

[0088] In step 2, the specific installation position of the track leg 1021 is along the length ...

Abstract

The invention relates to the technical field of immersed tube tunnel construction, in particular to a walking system of immersed tube tunnel formworks, a system and a walking implement method of the immersed tube tunnel formworks. According to the walking system, tracks passing through at least two immersed tube pouring areas are arranged, that is, tracks at least passing through a first immersedtube pouring area and a second immersed tube pouring area are arranged, a walking trolley capable of walking along the tracks is arranged on the tracks, a fixing frame is arranged on the walking trolley and used for mounting of retractable inside formwork supports, the inside forkmwork supports are used for connecting inside formworks, and after pouring is finished, the inside formwork supports drive the inside formworks to retract and can be used for next pouring directly. The walking system is matched with the retractable inside formwork supports, so that the inside formworks can be driven to be transported from a preceding immersed tube pouring area to the next immersed tube pouring area for pouring, disassembling and repeated mounting of the inside formworks and the inside formwork supports are avoided, and labor cost and time are saved.

Description

technical field [0001] The invention relates to the technical field of immersed tunnel construction, in particular to an immersed tunnel formwork walking system, an immersed tunnel formwork walking system, and an immersed tunnel formwork walking implementation method. Background technique [0002] Formwork engineering refers to a formwork formed by newly poured concrete and a complete set of structural systems to support the formwork. Among them, the structural part that touches the concrete and controls the predetermined size, shape, and position is called the formwork, and the work of making, assembling, using and dismantling the structural facilities used to shape the concrete in the concrete construction; a complete set of structural systems supporting the formwork refers to Rods, trusses, connectors, metal accessories, working bridges, etc. that support and fix the formwork constitute the supporting system. [0003] The existing immersed tube precast concrete pouring i...
