Pier construction technology

Abstract

The invention discloses a pier construction technology which comprises the steps of pier steel reinforcement framework manufacturing, concrete pouring, concrete curing, concrete temperature measurement and control, construction joint treatment, pier cap construction and support cushion stone construction. The pier construction technology has the beneficial effects that in the manufacturing process of the steel reinforcement framework, the main reinforcements and the stirrups are bound through the binding wires, deformation and loosening of the framework are prevented, pouring is carried out symmetrically and horizontally in the whole plane section of the pier body in a layering mode, it is guaranteed that concrete is compact and the surface is smooth and neat, and concrete curing facilitates improvement of the strength of the concrete; the concrete temperature is detected, when it is found that the concrete pouring temperature, the internal and external temperature difference or the cooling rate are abnormal, a worker can conduct timely treatment and construction joint treatment conveniently, the compactness of concrete at the joint is improved conveniently, after concrete pouring is completed, the surface of the concrete is trowelled and calendered in time, and sundries are prevented from blocking bolt holes.

Description

technical field [0001] The invention relates to a bridge pier construction, in particular to a bridge pier construction technology, which belongs to the technical field of building construction. Background technique [0002] With the rapid development of my country's economy and the rapid growth of urban population, the traffic volume has also increased, and the road traffic capacity is seriously insufficient. The construction of urban viaducts has also become a measure to relieve traffic pressure. In addition to the basic requirements, it is also necessary to minimize the construction period to reduce the impact on the surrounding traffic and shorten the urban traffic jam time. At present, the pier structure of urban bridges usually adopts cast-in-place construction, but there are some problems in this cast-in-place construction process. waste. Contents of the invention [0003] The purpose of the present invention is to provide a bridge pier construction technique in or...
