Description
Technical field
A kind of punching block lining trolley optimal number computational methods of the present invention, carry out lining cutting and apply simultaneously for many chassis of long tunnel
Man-hour telescoping steel form optimal number is calculated.
Background technology
In the processs of construction such as China's water power, traffic, it is frequently encountered first excavation and completes and then carry out concrete-lined
Tunnel.Wherein lining concrete construction speed is one kind of FAQs more slowly.Increase chassis quantity and be to speed up progress
One of modal method.But the increase of chassis quantity can cause to be interfered between each chassis, cause work efficiency to reduce.And
And increasing with chassis quantity, auxiliary facility can be caused to meet the requirement of chassis construction speed, the chassis work holdup is caused, affect
Efficiency of construction.How chassis quantity is reasonably arranged, reach the purpose of economical and efficient, be the weight in lining concrete detail design
Want content.
The content of the invention
The technical problem to be solved is to provide a kind of punching block lining trolley optimal number computational methods, to realize
Many chassis construction efficiency optimums and utilization rate of equipment and installations supreme good.
The technical scheme that the present invention takes is：A kind of punching block lining trolley optimal number computational methods, comprise the following steps：
Step 1：The time required to decomposing each operation of lining construction and determining single operation；
Step 2：Determine the minimum circulating process time t1 of separate unit car；
Step 3：Determining cannot parallel construction activity time t2 in the separate unit car circulating process time；
Step 4：It is determined that optimal chassis quantity=└ t1/t2 ┘.
A kind of punching block lining trolley optimal number computational methods, need not consider concrete process flow arrangement in calculating process.
Whole technological process is divided into the operation and the minimum circulating process two parts of separate unit car not limited by chassis use, no
The operation limited by chassis use, constructs in advance during construction depending on actual conditions, does not enter calculating.
The minimum circulating process of separate unit car is divided into can parallel construction operation and cannot parallel construction operation, it is impossible to parallel construction work
Sequence because take public resource must carry out by chassis by storehouse, can parallel construction operation by rational construction procedure in other chassis
The minimum circulating process of separate unit car is carried out during carrying out.
The minimum circulating process of separate unit car：Pour in circulation in Dan Cang, it is necessary to occupy whole operations that chassis could construct
With, the minimum circulating process of separate unit car of the present invention, comprising：Chassis position in storehouse is checked and accepted, chassis walking and formwork erection, concrete treat it is strong and
Form removal, concrete cast.
Can parallel construction operation：Refer to that in the minimum circulation technology of bicycle, when the operation is carried out, other chassis also can be same
The operation of Shi Jinhang same processes, it is of the present invention can parallel construction operation, comprising：Chassis position in storehouse is checked and accepted, chassis is walked and vertical
Mould, concrete treat strong and form removal.
Cannot parallel construction operation：Refer to that, when the operation is carried out, other chassis cannot be same in the minimum circulation technology of bicycle
The operation of Shi Jinhang identical operations, it is of the present invention cannot parallel construction operation include：Concrete is poured into a mould.
Can parallel construction operation other minimum circulating processes of chassis separate unit car be arranged in by rational construction carry out process
In carry out.Under normal conditions and in embodiment, i.e., the position in storehouse examination of any chassis, chassis are walked and formwork erection, concrete are treated
Strong and form removal can carry out position in storehouse examination, chassis walking and formwork erection, concrete and treat that strong and form removal, concrete are poured into a mould in other chassis
Carry out simultaneously in time period, the same time can only at most have a chassis to carry out concrete cast.
Nothing in punching block lining trolley optimal number=separate unit car minimum circulating process time t1/ separate unit car circulating process time
Method parallel construction activity time t2.
Quotient rounds up can cause chassis to leave unused, corollary equipment work is not full.Rounding downwards can cause corollary equipment
Idle, chassis work is not full.In view of situations such as maintaining, punching block lining trolley optimal number is rounded downwards.
A kind of punching block lining trolley optimal number computational methods of the present invention, have gathered the think of of parallel operations and cross construction
Think, by division and classification to operation, on the premise of having independently working condition operation in advance, during with separate unit car work cycle
Between and the concrete that wherein can only pour into a mould by car by storehouse pour into a mould operation and go out optimal chassis quantity for core calculations, entirely calculating
The impact that concrete process flow is arranged need not be considered in journey.
Specific embodiment
A kind of punching block lining trolley optimal number computational methods, comprise the following steps：
1) the time required to, decomposing each operation of lining construction and determining single operation：
According to lining concrete construction technology process, whole technological process is decomposed into successively：Floor (inverted arch) concrete
Cast, side and roof arch reinforcing bar system peace, concrete pump in place, position in storehouse examination, chassis walking and formwork erection, concrete cast, coagulation
Soil treats strong and form removal, the time required to then calculating single operation according to physical device ability and labour, also can be by actual survey
Calculate and obtain；
2) the minimum circulating process time t1 of separate unit car, is determined：
The workload of each punching block lining trolley is identical, can complete independently and by the construction constraint of other chassis with separate unit car
With all process steps for limiting as the minimum circulating process of separate unit car, it is included, and position in storehouse is checked and accepted, chassis walking and formwork erection, concrete are poured
Note, concrete treat strong and form removal, and separate unit car minimum circulating process time t1 as appeals four activity time sums；
3), determining cannot parallel construction activity time t2 in the separate unit car circulating process time：
In separate unit car circulating process cannot parallel construction operation be concrete cast, in the order chassis circulating process time
Cannot parallel construction activity time t2 be single storehouse concrete duration of pouring；
4) optimal chassis quantity, is determined：
When concrete cast is ceaselessly carried out in whole t1 time ranges, the efficiency highest of chassis.Therefore, optimal platform
Car quantity=└ t1/t2 ┘.I.e. optimal chassis quantity is：When separate unit car minimum circulating process time t1 is with separate unit car circulating process
Between in cannot parallel construction activity time t2 business and round downwards.
Embodiment：
a：The time required to decomposing each operation of lining construction and determining single operation；The cast of floor (inverted arch) concrete, side
Crown reinforcing bar system peace, concrete pump are in place, position in storehouse is checked and accepted：0.5h, chassis walking and formwork erection：10h, concrete cast：8h、
