Title:
MORTAR AND CONCRETE SPRAY METHOD AND SPRAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/221034
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a mortar and concrete spray method and spray device with which it is possible to improve the spray method quality by homogenizing a mixture of a granulated solidification material, an aggregate, and water. To achieve this purpose, a particulate granulated solidification material (M1) that has approximately the same specific gravity or particle size as an aggregate (M2) is used in the present invention. The present invention includes: a water-supplying system (100); a pumping system (200) that pumps a mixing material other than water (a mixture of the granulated solidification material and the aggregate); and a connecting system (300) that mixes water and the mixing material other than water, wherein the pumping system (200) includes a spraying apparatus (25) that pumps the mixing material other than water into the connecting system (300), a measuring device (3) that measures the mixing material discharge quantity from the spraying apparatus (25), and a control device (2) that computes a quantity of water to add and a flow rate of water relative to the mixing material discharge quantity to form a suitable mixture, and the water-supply system (100) has a water-feeding pump (32) that pumps water at the flow rate that was computed by the control device (2).
