Problems solved by technology

The hair agents used in engineering are all pre-prepared in the factory, and then transported to the construction site for dilution with water, and then the foaming process will cause foaming due to temperature, violent shaking, and uniformity of dilution during transportation. The foaming efficiency of the agent and the strength of the foam are greatly reduced

Embodiment

[0047] 1. Construction site preparation

[0048] Site preparation includes: leveling the site, cleaning the site garbage and floating dust, cleaning the floating soil in the site, so as not to affect the bonding force between the foam concrete and the base layer after pouring, keeping the site to be treated clean, flat, firm and dry; watering the site when the weather is dry Pretreatment, wet the site, sprinkle at least twice to increase the bonding force between the pouring layer and the base, but there should be no obvious water accumulation on the surface of the base, so as to prevent the foam in the foam concrete from breaking due to excessive water absorption at the base; The site is divided into an area of ​​less than 400m by formwork 2The area of ​​the formwork should be fixed with formwork brackets to prevent the formwork from collapsing due to the lateral pressure of the foam concrete during construction; the height of the formwork should be adjusted according to the ...

Abstract

The invention discloses a construction method of an air-encapsulated characteristic material in roads. The construction method comprises the following steps: 1) construction site preparation; 2) preparation of a cement slurry; 3) preparation of a foaming agent solution; 4) preparation of foams; 5) preparation of a foam concrete; 6) foam concrete pouring; and 7) foam concrete conservation. According to the construction method of the air-encapsulated characteristic material in the roads, the method is simple and convenient, and the problems existed in road high fill that foaming efficiency is low and strength of the foam concrete is uneven are solved.

Description

technical field [0001] The invention relates to a construction method of an air-wrapping characteristic material in roads. Background technique [0002] In the western part of China, the landform is dominated by mountains. The construction of expressways in mountainous areas is limited by the terrain, landform, and hydrogeological conditions. It is inevitable to carry out high-fill expansion construction on the original roadbed; at the same time, in order to meet the overall planning requirements of the country , and make better use of excavated earthwork resources, more and more high-fill roadbeds will be used in the reconstruction and expansion of expressways. In high-grade highways in mountainous areas, fill and excavation roadbeds account for 80%, and high fill embankments exceeding 20m are not rare. With the promotion of national policies and the rapid development of traffic construction, the structure of high embankments will be further improved in terms of quantity a...
