[0004] Most of the current concrete mixing plants are fixed, usually far away from the construction site, and need to be equipped with multiple mixer trucks, and the long transportation time will cause the concrete slump to decrease, which will affect the workability of the concrete. In order to compensate for the slump decrease, the It is necessary to increase the gradation of cement and set retarder, both of which lead to an increase in cost
In addition, the existing concrete mixing plant is assembled and occupies a large area, and the relocation is time-consuming and laborious, which affects work efficiency
The above factors lead to the fact that the concrete commercial production system often cannot meet the needs of concrete maintenance, which restricts the construction period and quality of expressway concrete engineering maintenance

Embodiment 1
[0042] Trial example 1: In the trial construction of a highway bridge deck pavement, the on-site pavement is 6m wide, 15cm thick, and 500m long. The fast mobile high-performance concrete mixing plant is about 50km away from the construction site. Select the fast mobile concrete mixing plant, first use the traction device 71 to transport the fast mobile concrete mixing plant to the bottom of the required construction bridge deck, and the traction device 71 pulls the fast mobile concrete mixing plant to travel at a speed of 50km per hour, 1 It is transported to the site in one hour, the trailer board 72 and equipment are supported by outriggers 73, quickly connected, assembled, debugged, and put into production, which is completed within 6 hours. Because carry out the concrete production of bridge deck pavement construction, so powder one selects cement for use, powder two selects fly ash for use, powder three selects mineral powder for use, carry out powder addition with powder ...

[0043] Trial example 2: The bridge deck of a highway is seriously damaged, and the old concrete on the bridge deck needs to be chiseled out before the bridge deck concrete repair construction is tried. The design strength of the bridge deck pavement repair concrete is C50, the design thickness is 20cm, the width is 7.5 meters, and the length is 500 meters. The fast mobile concrete mixing plant is about 120km away from the construction site. The traction equipment 71 transports the fast mobile concrete mixing plant to the underside of the bridge deck required for maintenance. The traction equipment 71 drives the fast mobile concrete mixing plant at a speed of 40km per hour, transports it to the site in 3 hours, and uses the outrigger 73 to pull the trailer The board 72 and the equipment are supported, quickly connected, assembled and debugged, and completed within 6 hours. Because of concrete production for bridge deck maintenance, cement is used as the first powder, fly ash is...

Abstract
The invention discloses a quickly-moving type concrete mixing station, and relates to the technical field of concrete production equipment. The station comprises an aggregate supplying system, a powdered auxiliary material supplying system, a liquid auxiliary material supplying system, a stirring system, a control panel, a pump delivery system, and a transportation system; wherein the transportation system comprises traction equipment and a trailer plate, the aggregate supplying system, the powdered auxiliary material supplying system, the liquid auxiliary material supply system, the stirring system, the control panel, and the pump delivery system are all arranged on the trailer plate; the aggregate supplying system, the powdered auxiliary material supplying system, and the liquid auxiliary material supplying system all communicate with the stirring system, the stirring system comprises a frame and a stirrer, the stirrer is arranged on the frame; and the pump delivery system is arranged below the material unloading door of the stirrer. The quickly-moving type concrete station has the advantages of compact structure, user-friendliness, and rapid movement, can shorten the construction time and guarantee the concrete quality, satisfies the using requirement of small-batch concrete, improves the construction efficiency, and saves the construction cost.
Description
technical field [0001] The invention relates to the technical field of concrete production equipment. Background technique [0002] In recent years, with the continuous improvement of my country's economic strength, my country's highways, especially expressways, have developed rapidly. With the rapid growth of traffic volume and increasingly heavy vehicle load, the impact force, dynamic load strength and fatigue effect of highway bridges are constantly increasing, so that the bridge deck is often in an overloaded state, resulting in many bridge deck pavements along the highway. A large number of damage phenomena such as rutting, shifting, cracking, delamination, and potholes not only directly affect the road performance of the bridge deck, but also greatly affect the durability and operational safety of the road, seriously affecting normal transportation ; In addition, in today's frequent occurrence of natural disasters, linear transportation infrastructure such as highways...
