Background

In recent years, with the continuous development of tunnel construction technology in China, in order to effectively improve the stability and durability of an inverted arch structure, new knowledge is provided for requirements of inverted arch construction. The template for inverted arch construction is optimized from a simple single small template to an integral type low-side wall inverted arch template driven by a trestle, and then is further optimized to a full inverted arch template of a full inverted arch section template. The tunnel inverted arch layer is constructed with full-width inverted arch template, and template cost increases to some extent, and inverted arch construction space is also compressed further, and when pouring construction, the inverted arch layer can't be vibrated comprehensively in the below of template. In actual construction application, air bubbles are easily formed on the surface of finally-formed inverted arch concrete, primary pulp plastering and timely secondary cleaning cannot be carried out on the surface of the inverted arch layer due to the existence of the full-width inverted arch template, and certain safety risks are accompanied when the appearance of the inverted arch layer is influenced by the air bubbles. Therefore, the prior art provides a sliding type inverted arch template or called a dragging template, the inverted arch template is divided into a left part and a right part, an arc-shaped track with the same surface shape as the inverted arch is arranged on the inverted arch template, and the left part and the right part of the template can slide left and right along the arc-shaped track. The sliding template overcomes the defects to a certain extent, but still cannot ensure the smoothness of the surface of the inverted arch layer, and particularly for a water diversion culvert, a large and small pit can be generated under the continuous scouring action of water flow, and the pit can be rapidly diffused, so that the service life of the project is seriously influenced.

Detailed Description

The invention is described in further detail below with reference to the drawings and specific examples.

As shown in fig. 1 and 2, the inverted arch concrete plastering device of the present embodiment includes a plastering roller 1 and two rows of guide rails 2, the guide rails 2 are arc rails 21, the two rows of arc rails 21 are arranged in parallel along the depth direction of the inverted arch (vertical paper direction in fig. 1), and the plastering roller 1 is movably disposed on the two rows of arc rails 21. Wherein, a power wheel can be arranged on the plastering roller 1, so that the plastering roller 1 can actively move along the guide track 2, or a driving mechanism can be arranged on the guide track 2, the driving mechanism drives the plastering roller 1 to move along the guide track 2, and the driving mechanism can be, for example, a chain wheel and a chain, a transmission chain wheel is correspondingly arranged on the plastering roller 1, or a hydraulic cylinder and the like; the plastering roller 1 can realize active rotation by the rotary driving force, or passively rotate after contacting with the concrete surface in the moving process.
