Cast-in-place concrete pile construction method based on BIM technology

Abstract

A cast-in-place concrete pile construction method based on the BIM technology comprises the steps that firstly, a construction area is built, a protective fence is built on a construction site, and an access door is arranged; step 2, building a BIM model: A, determining a model precision requirement: determining the precision of each model according to a design requirement; b, drawing a complex terrain: according to the geological exploration report, constructing a drawn terrain which is equal to the construction site in proportion in the revit; c, engineering pile reinforcing steel bar drawing, wherein engineering pile drawing is conducted according to engineering pile design drawing reinforcing steel bar nodes, and reinforcing steel bars automatically change according to different pile lengths; the invention aims to provide a BIM technology-based cast-in-place concrete pile construction method which can provide more intuitive, more accurate and faster construction information under the engineering conditions of complex engineering form, tight construction period and large engineering information amount, and a construction management and control system which is high in management efficiency, low in management cost, good in traceability, more intuitive and better in visibility.

Description

【Technical field】 [0001] The invention relates to the technical field of construction engineering, in particular to the technical field of concrete cast-in-place pile construction. 【Background technique】 [0002] Building Information Modeling (English name: Building Information Modeling, also known as Building Information Modeling, BIM for short) is a building or construction engineering information model that is composed of sufficient information to support the development and management of new products and can be directly interpreted by computer applications, that is, digital technology. Supported life cycle management of the built environment, it is a new tool for architecture, engineering and civil engineering, pioneered by Autodesk in 2002. [0003] At present, BIM technology integrates various data and information of the project through the three-dimensional model of the concrete cast-in-place pile project, and then simulates the real information of the pile concrete c...

AI Technical Summary

Problems solved by technology

[0003] At present, BIM technology integrates various data information of the project through the three-dimensional model of the concrete pouring pile project, and then simulates the real information of the pile concrete pouring project through the data information, but there are still large-scale concrete pouring pile projects, pile types, There are many problems, different design technical parameters, large amount of construction information, etc., and when the existing concrete pouring piles are constructed, the on-site construction still adopts the traditional paper bills as the management basis, and the manual sampling inspection of the weighbridge is used as the measurement method. The management and control methods and The means are still in the "people-oriented" control mode, which can no longer adapt to the current development of construction site informatization; its shortcomings are mainly reflected in:

[0004] 1. The management efficiency is low, and the information feedback on the concrete pouring situation is not timely and synchronized, which is not conducive to the understanding of the site situation by all relevant units;

[0005] 2. The management cost is high. From entering the site to the completion of concrete pouring, a lot of labor costs are spent to collect vouchers and make statistics;

[0006] 3. The traceability is poor, and the quality problems cannot be traced back to the concrete pouring location;

[0007] 4. Poor intuition and visibility
