The Extremely High Reinforced Concrete Core Tube Construction Technique Analysis

Along with the development of the national economy, the domestic city construction step of the big and medium-sized city is more and more quick. Marking in the city the key figures construct to tower aloft continuously.The high speed of the construction engineering technique leap, let the mankind live the space facing blue sky white cloud to postpone the exhibition increasingly, but the construction technique and constructions of the extremely high layer building manage one of the key factors that the level carries out this dream of" stretch hand and can take off the stars" exactly. This text just with the local and some city core tube of the extremely high television tower starts construction for the example, aiming at the present local and high new construction craft and method launch the treatise.This engineering key order is the deep time analyzes the engineering characteristics and holds the engineering a little bit difficult, the safety, economy, and reasonable of the engineering construction project are deeply analyzed and researched. To the control that under construction key of engineering order then exactly the place of the core of this topic research, its main research and analyze the perpendicular degree of extremely high layer control, the extremely high layer pumps the side that send to the concrete problem, the concrete crack control, the breeze lotus' carry to move the control, the temperature effect to transform the problem and concrete constringency Transforms to become the decisive problem of etc. of the causable floor elevation fixed position problem.Aim at the above problem, in the process of topic study, I study the group to pass to adopt the experience that the laser allows to keep the similar to the fixed position in the GPS world rechecks the method to control the perpendicular degree of the core tube, choose the very fit pump to send the equipments and carry on the reasonable cloth tube, basis engineering of technique the backlog excellent turn the match of the concrete than the design of control, sprinkle to build the ex- preparation to the choice, concrete of the material at first, the agitation and conveyances of the concrete, sprinkle to build to flap the Sprinkle to build and protect, and the finished product protection and the heat environment construction of control, to the breeze lotus carries the function, temperature effect, flexibility to transform, the constringency and Transforms change of calculation analysis combine various comprehensive means of etc. of the implement control, end complete the topic research of this time and attain the anticipant research target.
