实务21—25（Practice 21 - 25） 2A320020 construction schedule control The preparation of 2A320021 master plan of construction progress First, the preparation of the schedule can be divided into the Gantt chart and network planning Two, pipeline construction can be divided into water, different rhythm rhythm flow, non rhythm flow three Three, control of the progress of learning mainly study from the following four aspects: The construction characteristics and 1. rhythm flow Gantt chart and the calculation of the construction period The construction characteristics and 2. non rhythm flow Gantt chart and the calculation of the construction period Application of 3. ordinary double code network plan Application of 4. time scale network plan The first part of rhythm flow construction points of knowledge summary Rhythm flow construction pipeline construction parameters of 1. construction process (n) 2. team number (n) 3. construction segments (m) 4. waterbeat (T): a work team continued in a construction period of time 5. flow step (K): two adjacent work team has started work (the most reasonable minimum time interval) The 6. period (T) The characteristics of all the waterbeat are equal to each other; All flow step are equal to each other, and is equal to the waterbeat; The work of each professional team can work continuously, the construction period of time without intermission; The professional team is equal to the number of construction process. Duration calculation formula of T= (mr+n-1) K R: the number of construction Typical case analysis A case Background: A project consists of A, B, C three projects, respectively, laying foundation, backfill excavation engineering, it is in the plane is divided into four construction section, the waterbeat in each construction section of the sub project was 3 days. Question: 1. the characteristics of rhythm flow construction. 2. with rhythm flow method of construction construction and pipeline construction drawing Gantt chart. Step 3. de
