Description

Construction formwork and construction device for partition wall in tunnel

technical field

The utility model relates to the technical field of tunnel construction, in particular to a construction template for a partition wall in a tunnel and a construction device thereof.

Background technique

In the field of expressway construction in mountainous areas, due to the influence of terrain and landform, and in order to ensure technical and economic indicators and traffic safety, the problem of route alignment is mainly solved by setting up tunnels. Since the tunnel construction needs to adopt the most suitable and reasonable construction technology according to the layout method and surrounding rock type, in order to ensure the progress of the construction period and control the investment. When the tunnel length reaches a certain requirement, a split tunnel is generally used. When the tunnel length is relatively short, multi-arch tunnels should be used.

In the construction of the partition wall in the double-arch tunnel, the formwork is more important, and its selection directly affects the construction period. Due to the small cross-section of the pilot tunnel in the tunnel, it is not easy to disassemble and assemble the formwork, which affects the construction. In the prior art, hydraulic self-propelled formwork and assembled formwork are mostly used for construction.

The hydraulic self-propelled formwork is moved by a self-propelled motor. Generally, there are two structures. The first is that there are two walking tracks on one side of the partition wall, and the vertical line of the formwork center of gravity falls between the two tracks. Extra weight. In this structure, the formwork is operated by a hydraulic system, and the panels are connected to the main body of the formwork by support rods. The main body is supported on the side wall of the pilot tunnel through the support rods. It is mostly used for the construction of curved partition walls with main reinforcement. This structure has its own weight and steel consumption. The second is that there is a walking track on both sides of the middle partition wall, and the formwork is connected as a whole by the end I-beam to form a stable structure of its own. In this structure, the formwork is operated by a hydraulic system, and the panel is connected to the main body of the formwork by the support rod, and the main body is supported on the side wall of the pilot hole through the support rod. Compared with the first structure, the self-weight of this structure is reduced, but it is still heavier and more expensive. And it is not possible to construct reinforced partition walls. To sum up, the hydraulic self-propelled formwork is self-heavy and expensive, and the formwork is not easy to install and adjust in the narrow pilot hole space.

Assembled formwork generally has two structures. The first type is spliced by small steel molds. The formwork is internally connected by tensioned steel bars, and the supporting steel bars fix the position of the formwork. Externally, brackets or diagonal braces ensure the overall stability of the formwork. The formwork is manually installed, disassembled, and moved, which has the disadvantages of a large number of labor, cumbersome installation and disassembly, and time-consuming, and the small formwork is easily deformed; The lower part of the wall is backfilled with earth and stone after pouring. This structure has the disadvantages of large amount of labor, long time consumption, and difficult control of pouring quality. In summary, the assembled formwork has cumbersome installation, long construction period, high construction cost of the middle partition wall and poor appearance.

Therefore, relying on many years of experience and practice in related industries, the inventor proposes a construction formwork for a partition wall in a tunnel and a construction device thereof to overcome the defects of the prior art.
