Description

Sand and stone treatment device and method for civil engineering construction

Technical Field

The invention relates to the technical field of civil engineering sand and stone refining and screening, in particular to a sand and stone treatment device and method for civil engineering construction.

Background

Civil engineering is a general term for scientific technology for building various land engineering facilities.

It refers to both the materials, equipment used and the technical activities carried out such as surveying, designing, construction, maintenance, repair, etc., as well as the objects of engineering construction.

Civil engineering is the construction of various engineering facilities, such as houses, roads, railways, pipes, tunnels, bridges, canals, dams, ports, power stations, airports, ocean platforms, water supply and drainage and protection projects, on the ground or underground, on land, directly or indirectly serving human life, production, military and scientific research.

The civil engineering refers to engineering entities for surveying, planning, designing, constructing, installing and maintaining various technical works and the like of newly-built, reconstructed or expanded buildings, structures, related supporting facilities and the like of various projects except house buildings.

The fundamental problem to be solved in civil engineering is the safety of engineering, so that the structure can resist various natural or artificial acting forces, any engineering structure bears the self weight and the action of using load and wind force, the humidity change can also produce force action on the civil engineering structure, the civil engineering structure also needs to consider resisting the earthquake action in an earthquake area, and in addition, the influence of artificial actions such as explosion, vibration and the like on the civil engineering can not be ignored.

The materials are the basic conditions for realizing civil engineering construction, the task of civil engineering is to fully play the role of the materials and realize the most economical construction on the premise of ensuring the structure safety, and therefore, the selection of the materials and the determination of the quantity are important contents which must be solved in the process of civil engineering construction.

Civil engineering often need use gravel and sand processing apparatus in the work progress, mainly because mix impurity such as stone very easily in the sand, need sieve through No. two screens before using, guarantee to use the quality of gravel and sand to ensure engineering quality, eliminate the potential safety hazard.

In addition, the inventor actually discovers that randomness exists in the source batches of the sand and the stone during construction; adopting the sand and stones in the same batch, wherein the particle sizes of the sand are not greatly different; if the gravel and sand of different batches, there is certain disparity in particle size, if different batches are used jointly, most of current processing apparatus can only realize the function of edulcoration, can not unify the gravel and sand particle size of different batches, consequently still have the demand of carrying out refining to the gravel and sand to the high-efficient simple and convenient operation of refining the processing will be realized.

Therefore, the inventor designs a sand and stone treatment device and a sand and stone treatment method for civil engineering construction, and solves the problems.
