The construction speed of pier depends on the structural form of pier. The difference between the quantities of steel bars and concrete is too great, and so is the difference in height and structure (the difference between hollow thin-walled piers and solid piers is much different), so it cannot be generalized.

Pier is the lower load-bearing object used to bear the upper structure in civil engineering. The cross sections of piers are mostly circular, and there are also anisotropic piers such as elliptical, square, curved and parabolic. It is an important part of highway bridges, railway bridges, sidewalks and other bridges, overpasses, ramp bridges, overpasses and other projects. As an important part of the bridge, pier design and quality management have a far-reaching impact on the overall stability of the bridge. To strengthen the quality management of pier appearance construction, we should start with the management of raw materials, construction personnel and construction technology, and formulate corresponding solutions for the phenomena such as pits, bubbles, honeycombs and watermarks to ensure that the pier appearance meets the basic requirements. The main body of pier appearance construction is the construction personnel, so strengthening the control of the construction personnel is an important way to improve the quality of pier appearance. First of all, according to the requirements of pier construction, the construction personnel should be trained scientifically. On the one hand, it is necessary to improve the professional quality of construction personnel, make clear their comprehensive quality and knowledge background, and thus formulate targeted training work. On the other hand, it is necessary to strengthen the control of construction personnel, establish a dynamic supervision system, and realize the dispatch and command of construction personnel, thus improving the appearance quality of piers.
