Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of retaining wall construction, in particular to concrete pouring equipment for retaining wall construction. Background Art
[0002] A retaining wall refers to a slope built with stones, cement, etc. on the river bank or roadside to prevent erosion by rivers or rainwater. A retaining wall is a wall set up to stabilize the natural slope of soil. It is a wall built to resist lateral pressure other than wind pressure; especially a wall to prevent landslides. Concrete pouring is an important link in the construction of retaining walls. When pouring retaining walls, the concrete pouring pipe outlet is the concrete pipe outlet of a concrete pump truck or a concrete pump pipe outlet. When the pouring surface is higher than the ground or the pouring formwork is higher, for example, a string tube needs to be placed between the pipe outlet and the pouring surface during the pouring of the retaining wall. Otherwise, when the concrete falls rapidly from a high place, a large amount of stone aggregate will be formed around the pouring point, and the mortar will be hit by the stone to the edge far from the pouring point, resulting in uneven mixing of the stone and mortar in the casting body. However, since there is still a certain height difference between the string tube and the pouring surface, the poured concrete will be mixed with air when it falls, resulting in bubbles inside the concrete, affecting the quality of the concrete and causing the concrete product to be unqualified. For this reason, we have proposed concrete pouring equipment for retaining wall construction. Utility Model Content
