Problems solved by technology

[0003]The lining of the steel lining is poured in stages. During the tunnel lining construction process, the steel lining is manually welded by loose assembly and rounding. The interior of the steel lining Steel pipe support is used, and the steel lining is used as the steel mold to carry out the concrete lining construction. No large-scale equipment is required during the construction process, but the quality of the manually welded steel lining is difficult to guarantee, and the construction speed is slow.
[0004] Steel pipe assembly and welding special rounding + pouring lining, often used in the construction of circular steel-lined tunnels without lining steel bars. The steel pipe welding machine performs rounding of steel pipes at the end of the tunnel, and uses the steel lining transport trolley to transport the steel lining to the designated location , for positioning and installation, using steel pipes to support the inside of the steel lining, and using the steel lining as a steel mold to carry out concrete lining construction. This method guarantees the construction quality of the steel pipe circle, but it is difficult to construct if it encounters a lining with steel bars , and the price of the special welding machine for steel pipe assembly is relatively high, and the economical and technical cost performance is relatively low

Embodiment 1

[0044] see Figure 1-6 , a construction system for the combination of horizontal and vertical rotation of a circular strip steel lined tunnel, which includes a steel lining circle system 1 for assembling three steel lining circles, and a track 6 is laid inside the tunnel, and the track 6 is equipped with a steel lining transport trolley 5 for steel lining 3 transportation by rolling fit, and a steel lining lifting and transportation device 4 for steel lining 3 hoisting and steering is arranged on the top of the tunnel, and a useful The needle beam trolley device is supported by the steel lining 3 for positioning and conveying. The construction system adopting the above-mentioned structure can be used for the lining construction of the circular strip steel-lined tunnel, thereby effectively solving the problems of narrow space and more interference in the construction process of the lining steel bars and the steel lining. For tight spaces, the work efficiency of concrete lining...

Embodiment 2

[0050] Such as Figure 7-10 , the method for the construction of the tunnel lining by the construction system of the circular band steel lined tunnel combined horizontally and vertically, is characterized in that it comprises the following steps:

[0051] Reasonably divide the steel lining into sections and tiles;

[0052] Step 2, complete the processing of system components according to the design requirements;

[0053] Step 3: According to the construction organization arrangement and the operation requirements of the system, rationally plan and set up the outrigger foundation, and install the track 6;

[0054] Step 4, binding concrete lining reinforcement;

[0055] Step five, carry out the steel lining horizontal and horizontal grouping, hoisting and vertical rotation, and assembly construction;

[0056] Step 6, carry out lining concrete construction;

[0057] Step 7, after the concrete strength meets the design requirements, the equipment moves to the next construction...

Abstract

The present invention provides a construction system and method for the combination of horizontal and vertical rotation of a circular strip steel lined tunnel, which includes a steel lining circle assembly system for steel lining assembly, and is laid inside the tunnel. There are rails, on which a steel lining transport trolley for steel lining transportation is installed through rolling fit, a steel lining lifting and transportation device for steel lining hoisting and steering is installed on the top of the tunnel, and a steel lining transportation device is also installed inside the tunnel There is a needle beam trolley device for steel lining support positioning and conveying. Through this method, the welding quality of the steel inner lining is improved, the construction speed of the lining is accelerated, and the application range of common construction methods is further expanded, and the difficult problem of construction of the tunnel lining with a steel inner lining under the condition of limited space is solved.

Description

technical field [0001] The invention belongs to the field of tunnel lining construction, and in particular relates to a construction system and method for combining horizontal and vertical rotation of a circular steel-lined tunnel. Background technique [0002] In China, there are many construction methods for circular tunnel lining with steel lining, such as "scattered steel lining and pouring lining in stages", "steel pipe assembly welding special round + pouring lining" and so on. [0003] Scattered steel lining is poured in stages. In the tunnel lining construction process, the steel lining is welded manually by using loose assembly and welding. The inside of the steel lining is supported by steel pipes. The steel lining is used as a steel mold to carry out the concrete lining. Construction, no large-scale equipment is required in the construction process, but the quality of the artificially welded steel lining is difficult to guarantee, and the construction speed is slo...
