Fast-construction method of concrete

Abstract

The invention discloses a fast-construction method of concrete, belonging to the technical field of building construction. The fast-construction method of concrete comprises the following steps, trialmixing of concrete raw materials, measurement of concrete raw material proportion, concrete batching and mixing production, concrete mixing test, concrete loading and unloading, and wet shotcrete construction. Before the wet spraying machine sprays concrete onto the damaged bridge deck, crack self-healing blocks are added, which is convenient for the staff to repair the damaged bridge deck quickly, at the same time, the time required to partition the bridge deck construction due to repair work is reduced when the staff repairs the damaged bridge deck. It is convenient to reduce traffic congestion caused by limited vehicle flow and avoid traffic accidents caused by damaged bridge deck construction after traffic bridge deck is damaged, which greatly improves bridge deck traffic capacity andservice level, and reduces the contradiction between bridge deck maintenance and normal traffic operation.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a rapid concrete construction method. Background technique [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate, mixed with water in a certain proportion, and then stirred, formed and maintained. It is also called ordinary concrete. It is widely used in There are strict laws and regulations to regulate any small link in civil engineering and concrete engineering construction. In recent years, with the continuous improvement of my country's economic strength, my country's transportation industry has also developed rapidly. At the same time, With the rapid growth of traffic volume and increasingly heavy vehicle load, the impac...

Problems solved by technology

[0003] In order to restore the road performance of the bridge deck as soon as possible and reduce the impact of bridge deck damage on transportation, construction personnel need to repair and maintain the damaged bridge deck. When construction personnel are required to repair the bridge deck, Especially when part of the bridge deck is damaged in a large area, construction workers need to separate the damaged bridge deck. In this case, part of the damaged bridge deck is often unusable, restricting the original traffic flow, and causing Traffic congestion can even easily induce traffic accidents, reduce the traffic capacity and service level of the bridge deck, and make the contradiction between bridge deck maintenance and normal traffic operation increasingly prominent, which not only affects the normal development of the economy, but also brings considerable traffic problems to traffic managers. great social pressure
