Description

[0002] With the rapid development of society, road construction is particularly important. Building roads can facilitate people's travel and the transportation of goods. In the process of road construction, the roadbed needs to be reinforced. In some lakeside or coastal areas, the roadbeds of many roads are soft soil roadbeds, which have high water content, large porosity, low permeability and high compressibility. This can easily lead to vertical settlement and lateral deformation in the later use of the road. During the construction process, some reinforcement operations are carried out on this soft soil roadbed, including the operation of spreading lime.

[0003] In the prior art, there is a construction device for a soft base road surface (Announcement No.: CN217758195U), the structure of which includes a box, the inner wall of the box is fixedly connected with a partition, the inner bottom wall of the box is fixedly connected with a material pump, the input end of the material pump is fixedly connected with a pumping pipe, the top of the pumping pipe is fixedly connected with the upper surface of the partition, the output end of the material pump is fixedly connected with a discharge pipe, the left end of the discharge pipe passes through the box and is fixedly connected with a spray head, the upper surface of the box is fixedly connected with a crushing box, the inner wall of the crushing box is fixedly inlaid with a first bearing, and one side of the crushing box is fixedly inlaid with a second bearing. Although the construction device for a soft base road surface can be used to suck powdered lime through the coordination of the material pump, the spray head, the pumping pipe and the discharge pipe, the powdered lime can be allowed to enter the interior of the spray head, the lime can be scattered, and the efficiency of lime scattering can be improved.
