As for the same working condition and construction structure, let's
take the ground handling of one site in Qingdao city as an example:
Both of them have three units with 32 floors and the total area is
32000 m2, the following is the comprehensive comparison between
fine stone concrete pumps and construction elevators for conveying.
1. Personnel allocation for fine stone concrete pumps as shown as
1, 2(4), 2, 2, 2, 4, 15.
One fine stone concrete pump operator, two sets of blenders and two
operators for each blender (totally 4 persons), two persons for
concrete supplying, two persons for ground cleaning, two persons
for concrete pouring, and four persons for smoothing ground,
totally 15 persons.
, 12m³/h(, 20m³/h), 12m³/h*8h=96m³, 5-6cm, 1920, 128, 17.
Generally, the average conveying capacity is 12m³/h (the data
includes machine shut down time, and the theoretical conveying
capacity of fine stone pump is 20m³/h), conveying capacity of every
day is 12m³/h*8h=96m³, and construction surface is 5-6cm in
thickness, so every day can make 1920, and the average work for
each people is 128, which totally needs 17 days for finishing this
2. Personnel allocation for construction elevator is shown as the
2/2/2/8/2/4/2, 22., 6, 120.06m³, 1612, 8, 12*0.06*8*4=23m³, 460, 21, 70.
Two persons for two sets of blenders, two persons for concrete
supplying, two persons for carrying sand and stone, 8 persons for
transportation, two cleaners, four persons for concrete pouring,
and two persons for ground smoothing, totally 22 persons. Usually, construction elevator can carry two transporting
vehicles at each time, low-rise floor costs 6 minutes and high-rise
floor takes 12 minutes for one lifting and each vehicle can carry
0.06m³, so each hour there can be 12 vehicles in 6 times of
transporting, if we take 8 people divided into four groups for
counting: 12 vehicles *0.06*8*4=23m³, so every day can have 460 and
per capita is 21, which needs 70 days for finishing this work.
