Description

Technical Field

[0001] This invention belongs to the field of transportation civil engineering technology, specifically relating to a method for calculating the minimum number of transport vehicles for cement-stabilized crushed stone considering continuous production. Background Technology

[0002] During the construction of cement-stabilized crushed stone subbase and base course, a certain number of transport vehicles are required to transport the cement-stabilized crushed stone mixture mixed in the mixing plant to the construction site. After being unloaded by the transport vehicles into the paver hopper, the mixture is then spread, compacted, and cured to complete the construction.

[0003] During the construction of cement-stabilized crushed stone, continuous and uninterrupted construction must be ensured. If the construction process is interrupted or discontinuous, hidden construction joints will appear due to the difference in cement setting and hardening time, and the base layer will crack under low temperature conditions.

[0004] Transportation capacity is essential for ensuring continuous and uninterrupted construction of cement-stabilized crushed stone, but it is often overlooked during construction. When equipping cement-stabilized crushed stone transport vehicles, they are often arranged arbitrarily based on past experience, resulting in the inability of transport vehicles to guarantee continuous and uninterrupted construction. Construction sites frequently experience pauses or even long-term interruptions, affecting the construction quality of cement-stabilized crushed stone. Summary of the Invention

[0005] The purpose of this invention is to provide a method for calculating the minimum number of transport vehicles for cement-stabilized crushed stone production that takes into account continuous production. This method ensures that the cement-stabilized crushed stone production can be carried out with the minimum number of transport vehicles, thereby saving resources.

[0006] To achieve the above objectives, the technical solution adopted by this invention is: a method for calculating the minimum number of transport vehicles for cement-stabilized crushed stone considering continuous production, specifically implemented according to the following steps: Step 1: Obtain the output admixture of the cement-stabilized crushed stone mixing plant, denoted as [missing information]. C ; Step 2, obtain the transport capacity of a transport vehicle, denoted as Y ; Step 3: Obtain the time taken for the transport vehicles to travel from the mixing plant to the construction site after loading, and record it as follows: t 1; Step 4: Obtain the time from when the transport vehicle arrives at the paving site to when the vehicle unloads and paving begins, and record it as _____. t 2; Step 5: Obtain the time required to pave the cement-stabilized crushed stone mixture for one transport vehicle, denoted as . t 3; Step 6: Obtain the time it takes for a transport vehicle to return empty to the mixing plant after paving is completed, and record it as _____. t 4; Step 7: Based on the results obtained in Steps 1-6, establish the minimum vehicle calculation formula, and obtain the minimum number of transport vehicles required for continuous production of cement-stabilized crushed stone through the minimum vehicle calculation formula.

[0007] As a preferred technical solution of the present invention, the C, Y, obtained in steps 1-6 t 1. t 2. t 3. t 4 represents the average value obtained after multiple tests.

[0008] As a preferred technical solution of the present invention, the formula for calculating the minimum number of vehicles is: .

[0009] The beneficial effects of this invention are as follows: This invention provides a method for calculating the minimum number of transport vehicles required for continuous production of cement-stabilized crushed stone. Based on factors such as the output of the mixing plant, the vehicle's transport capacity, the time it takes for the transport vehicle to leave the plant after loading and arrive at the construction site, the waiting time for paving, the paving time, and the time it takes for the empty vehicle to return to the mixing plant, the method can accurately calculate the number of transport vehicles required to ensure continuous and uninterrupted construction of cement-stabilized crushed stone. This avoids the arbitrariness in the allocation of transport vehicles during the traditional cement-stabilized crushed stone construction process and reduces the risk of hidden construction joints caused by intermittent construction, which could lead to cracking of the cement-stabilized crushed stone base layer.
