High pressure grouting construction method using steel structure and CGM materials

Abstract

The invention discloses a high pressure grouting construction method using a steel structure and CGM materials. The high pressure grouting construction method specifically comprises the following steps that 1, grouting materials are mixed; 2, grouting holes are connected and arranged; 3, air vents are connected and arranged; 4, grouting is carried; 5, air vents are examined; and 6, the compactnessof the grouting is detected using an ultrasonic opposite measurement method. According to the high pressure grouting construction method using the steel structure and the CGM materials, the high self-fluidity and non-shrinkage of CGM grouting materials and the non-porosity of high-pressure grouting are used fully, and sufficient compaction of concrete in the steel structure is ensured; and the high pressure grouting construction method using the steel structure and the CGM materials are high in degree of mechanization, energy-saving and environmentally friendly, good in construction quality and high in construction safety, and is applicable to the construction of concrete-filled steel tube in the construction structure, such as concrete-filled steel tube columns, concrete-filled steel tube beams, and steel tube truss web concrete.

Description

technical field [0001] The invention relates to the construction field, in particular to a high-pressure grouting construction method using steel structures and CGM materials. Background technique [0002] At present, the country is in the construction stage, and the construction industry is developing rapidly and in full swing, covering all regions of the country, with novel and diverse architectural styles. The construction industry is an industry that revolves around the design, construction, decoration and management of buildings. Urban architecture is an important part of the city, and architecture is not just an artificial work for people to stay, rest, and entertain. It is related to our economy, culture, and life in a large way. [0003] At present, in my country's construction industry, most steel frames combined with core tubes, shear walls and other structures are used as the main structural form of high-rise buildings, and concrete filled steel tubes have become...

Problems solved by technology

In ordinary concrete-filled steel tube construction, self-compacting concrete is usually used, and concrete pouring holes are reserved on steel members, and hoppers are used for manual pouring. This method requires a lot of personnel, low construction efficiency, and high material loss rate; It is required to reserve large holes, which will affect the strength and integrity of the structure. Manually poured steel pipe concrete cannot be vibrated. Even if self-compacting concrete is used, the degree of compactness is still difficult to guarantee, which brings hidden dangers to the service life of the building.
