Embodiment Construction

[0023] The present invention is described in further detail below by embodiment, and embodiment is only used for illustrating the present invention, does not limit the scope of the present invention.

[0024] The specific construction process of the M5 highway project in Pakistan will be described below.

[0025] The New Jersey guardrail of this project is constructed with high-performance multifunctional cement slip-form paver. The concrete strength used is A1 (3000psi, about 20Mpa), which is high plasticity and low slump concrete.

[0026] see Figure 1-4 A method for controlling the appearance quality of the guardrail in New Jersey after the slipform paver construction is shown, including the following steps:

[0027] Step 1: Flattening and compacting: After the concrete is preliminarily formed by the slipform paver template, the small pits on the surface of the New Jersey guardrail 1 and the small cracks on the top surface shall be flattened immediately, and the mortar or...

Abstract

The invention belongs to the field of highway engineering New Jersey barrier construction, and particularly relates to a method for controlling the appearance quality of a New Jersey barrier after construction of a slip form paver, which comprises the steps of flattening, rough plastering, fine plastering, side leaning, top leaning, self-made scraper treatment, final plastering and the like. The method for controlling the appearance quality of a New Jersey barrier after construction of a slip form paver has the advantages that the quality defects that pits, rough surfaces, poor line types andthe like appear on the surface of concrete after a New Jersey barrier is primarily formed are overcome, so that the final New Jersey barrier has the effects of consistent size, clear edges and corners, strong stereoscopic impression, overall attractiveness and consistent color; the method provided by the invention is easy to operate, does not need to additionally increase excessive resources, andis low in cost.

Description

technical field [0001] The invention belongs to the field of highway engineering New Jersey guardrail construction, and in particular relates to a method for controlling the appearance quality of the New Jersey guardrail after construction by a slip form paver. Background technique [0002] The existing technologies are mainly divided into three categories: prefabricated installation, formwork cast-in-place, and new slip-form paver construction. The first two are traditional manual construction. The guardrail concrete can be repaired twice to ensure the appearance quality, but the relative efficiency Low cost and high cost; the construction of new slip-form paver has high production efficiency. In fact, despite the use of advanced equipment and optimized construction technology, the surface of the guardrail produced by the slipform paver still has apparent defects such as pits, rough surfaces, and poor line shapes, which are inevitable. After checking the data, there is no ...
