Problems solved by technology

[0002] In the past, when spraying mortar or concrete on the pre-formed formwork on a high slope to form a grid-shaped slope protection, water, cement, and aggregates were mixed in advance to form the sprayed material, and the aforementioned sprayed material was sent by conveying pipes. In the mortar or

Abstract

A device for spraying mortar or concrete and a method of spraying mortar or concrete that enable smooth and reliable spray of mortar or concrete even if long distance transportation is involved. A device for spraying mortar or concrete, separately sending aggregate and cement milk forming mortar or concrete and then mixing them for spraying. The device has an aggregate pressure-sending machine for sending the aggregate by pressure and a transportation tube connected to the aggregate pressure-sending machine. The aggregate pressure-sending machine has a container for receiving the aggregate and a send-out section provided on the lower side of the container so as to communicate with the inside of the container through a communication opening. To the send-out section is connected the transportation tube. The aggregate dropped from the inside of the container to the send-out section through the communication hole provided in the bottom wall of the container is sent out into the transportation tube. The opening area of the communication hole is not more than the area of a flow path in the transportation tube.

Description

technical field [0001] The present invention relates to a mortar or concrete spraying device and a mortar or concrete spraying method using the device. Background technique [0002] In the past, when spraying mortar or concrete on the pre-formed formwork on a high slope to form a grid-shaped slope protection, water, cement, and aggregates were mixed in advance to form the sprayed material, and the aforementioned sprayed material was sent by conveying pipes. In the mortar or concrete spraying device, the pressure feeding resistance of the above-mentioned spraying material passing through the conveying pipe is very large, and the spraying material cannot be discharged at the expected discharge volume (pressure). It is very difficult or even impossible to spray the material. [0003] Therefore, the applicant of the present application is developing a cement that constitutes mortar or concrete as shown in the following patent document 1 in order to more efficiently carry out sp...
