The concrete has the characteristics of rich raw materials, low price and simple production process, so that the consumption of the concrete is increased more and more. Meanwhile, the concrete also has the characteristics of high compressive strength, good durability, wide strength grade range and the like. These characteristics make it very widely used, not only in various civil engineering, that is shipbuilding, machinery industry, ocean development, geothermal engineering, etc., but also concrete is an important material.

Concrete pumping transportation, including piston type and pneumatic type, is often used in the circumstances of inconvenient transportation and large concrete, and the transportation speed is high, but can be limited by site conditions. A concrete delivery pump, also known as a concrete pump, consists of a pump body and a delivery pipe, is a machine for continuously delivering concrete along a pipeline by using pressure, is mainly applied to building construction, bridge and tunnel construction, and is mainly divided into a gate valve concrete delivery pump and an S valve concrete delivery pump. The other is a pump truck which is formed by mounting a pump body on a chassis of a vehicle and then assembling a telescopic or bendable distributing rod. However, the concrete transportation mode in the prior art has the phenomenon of pipe blockage, and mainly comprises the following steps: the jam of distributing valve discharge gate department, the jam of feed inlet department, concrete conveying pipe block up, pipe valve department blocks up, no matter which kind of jam mode, all needs artificial mode to go to discharge the trouble, not only wastes time and energy, influences the time limit for a project, and when concrete was in intraductal, because under the gravity of self and inclosed environment, also takes place the segregation phenomenon easily. There are even serious safety concerns.

Further, structural cracks are generated due to concrete segregation, the homogeneity of concrete is reduced due to the concrete segregation, and severe cracking of the floor slab occurs due to the concrete segregation during the construction of the floor slab in muddy days. Finally, concrete segregation reduces the durability of the concrete structure, which reduces the concrete's impermeability and frost resistance. The applicant's research on the prior art belt conveyors has found that the above-mentioned problems are mainly caused by the continuous vibration generated by the rollers of the belt conveyors and are limited by the site by the problems due to the mechanical structure of the belt conveyors themselves. In view of the above, a transportation method with better technical effect is needed to solve the above problems.
