Problems solved by technology

[0005] In order to solve the above problems, the present invention provides a construction method for viaduct construction, which can solve the problem that since the surface of the formwork is usually a flat plate structure, it is difficult to closely fit when spraying the surface of the guardrail at the bend, and when the reflective paint is sprayed on the bottom After painting, the excess paint will flow downward from the gap between the formwork and the inner wall of the guardrail, thereby polluting the inner wall of the guardrail and affecting the aesthetics, and the formwork and the guardrail need to be repositioned every time they are attached, prolonging the working time and other problems

Embodiment Construction

[0031] In order to make it easy to understand the technical means, creation features, achieved goals and effects of the present invention, the present invention will be further described below with reference to the specific figures. It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict.

[0032] like Figure 1 to Figure 6 As shown, a construction method for a viaduct construction project, which uses a marking spraying equipment, the marking spraying equipment comprises a mobile platform 1, a frame unit 2, two rolling units 3, a spraying frame 4 and a telescopic tube 5, using the above-mentioned marking The construction method of spraying equipment for the viaduct construction project is as follows:

[0033] S1. Primer spraying: clean the surface of the guardrails on both sides of the viaduct, and uniformly spray the primer on the inner walls of the viaduct;

[0034] S2...

Abstract

The invention provides a construction method for viaduct construction. The operation is completed by the cooperation of a mobile platform, a frame unit, two rolling units, a spraying frame and a telescopic tube. When the surface of the guardrail at the bend is sprayed, it is difficult to fit tightly. When the reflective paint is sprayed on the primer, the excess paint will flow down from the gap between the template and the inner wall of the guardrail, thereby polluting the inner wall of the guardrail and affecting the aesthetics. The formwork and the guardrail need to be repositioned each time they are fitted together, prolonging the working time and other issues.

Description

technical field [0001] The invention relates to the technical field of viaduct construction, in particular to a construction method for viaduct construction engineering. Background technique [0002] Viaduct, a type of bridge, generally refers to bridges that span deep ravines in place of high embankments, and bridges spanning roads in urban bridges, supported by tall pylons or pillars. The use of this bridge structure can evacuate traffic density and improve transportation efficiency. During the construction of the viaduct, it is necessary to spray reflective paint on the guardrail on the edge of the viaduct, thereby improving the warning effect of the anti-collision guardrail and reducing the accident rate. [0003] When spraying the guardrail, the arrow template is usually attached to the inner sidewall of the guardrail, and then the reflective paint is sprayed on the inner sidewall of the guardrail by spraying. However, some problems may be encountered in actual operati...
