Degree, and heavy roller rolling. The engineering quantity is calculated in square meters according to the design size.
Sub-specifications of subgrade blind ditch are calculated in linear meters according to the design length.
The following aspects should be paid attention to in the calculation of elastic soft soil foundation treatment:
(1) mixed with dry soil and lime. The replacement of slag and flaky is calculated in cubic meters according to the design size.
(2) The specifications of the lime-sand pile shall be calculated according to the design drawings.
(3) Cement stabilized soil and mechanical drying are calculated in square meters according to the design size.
(4) The sub-thickness of sand bottom is calculated in square meters according to the design size.
(5) The thickness of paving layer is calculated in square meters according to the design size.
Calculation rules and explanation of subgrade (trough) engineering quantity
(1) The formation of subgrade (groove) is based on quality inspection standards. Road bed (trough) should meet the design elevation requirements after shaping and rolling, as follows
Laying structural layers to save raw materials. The contents include digging high, filling low and leveling, with an average thickness of 10cm.
Subgrade, rolled and formed. Manual or mechanical operation shall be determined according to the construction organization design.
(2) The quantity of subgrade works is designed subgrade width × designed road length. If the design subgrade width is not clear, it should be calculated according to the design structure width.
The side is widened by 40 cm.
(3) Blind ditch, also known as culvert, is an underground drainage seepage ditch, which can cut off or intercept interlayer water or a small amount of spring water flowing to subgrade.
Water can be used to lower the groundwater level. It is made of coarse-grained stone with high water permeability.
(4) The blind ditch of filter pipe is an underground ditch laid by pipeline, and there are some small holes for filtering water on the top and side.
(5) The unit of measurement is "meter", and the work includes digging, transporting materials, filling, tamping, and dumping soil outside the subgrade.
.
(6) The treatment of elastic soft soil foundation mainly solves the project that the moisture content of road bed is too large and the elasticity is soft, and the adopted process items include mixing dry soil and machinery.
Turn the sun, change aggregate, etc.
(7) On-site visas are generally processed according to the scope, methods and materials, and project settlement is calculated according to the visa form. organize personnel
In the construction drawing budget, the engineering quantity is estimated according to the geological conditions.
