When pouring concrete thin-walled structures such as drainage ditches,due to the narrow feeding port of the template,the thin-walled structure that needs to be continuously poured is longer,and the internal steel bars are denser,which limits the speed of concrete pouring and leads to serious waste of material.A thin-walled component pouring auxiliary device is developed combined with a certain wharf yard project,which has the advantages of smooth feeding,continuous construction,low device cost,and reusability.When pouring concrete for drainage ditch walls,the device overcomes the drawbacks of traditional drainage ditch pouring methods,such as low efficiency and excessive waste of concrete,and improves the efficiency of drainage ditch pouring construction by 50%.
