Embodiment Construction

[0027] Embodiments of the present invention will be described below. Concrete pump truck for pressure conveying concrete figure 1 As shown, it is composed of the following parts, which include: a car 2, which runs by itself with an engine; a hopper 3, which is fixed to the rear of the chassis of the car 2, and pours concrete into the hopper Middle; concrete pump, the concrete pump pressurizes the concrete from the hopper 3; the multi-section arm 4, the end of the multi-section arm 4 is connected to the front of the car 2; the concrete delivery pipe 6, the concrete delivery pipe 6 is supported by the multi-section arm 4 and bends together with the multi-section arm 4 . Although in figure 1 The concrete pump is not shown in , but the concrete pump is composed of a pair of piston pumps, and when these concrete pumps are mutually driven, the concrete is pressure-fed inside the concrete delivery pipe 6 with pulsation. In the present embodiment, an opening 7 is provided in a pa...

Abstract

Provided is a prescribed apparatus to start pressure-feeding concrete using a concrete transport tube without requiring preceding mortar. The invention is configured as a plug (10) to be inserted intoa concrete transport tube (6) prior to starting pressure-feeding concrete. When the plug is inserted into a concrete transport tube prior to starting pressure-feeding concrete, the plug (10) elastically deforms and adheres liquid-tight at a prescribed pressure to the inner circumferential face of the concrete transport tube (6). When concrete (22) starts to be pressure-fed with a concrete pump, the plug (10) is pushed by the front edge of the fed concrete (22) and advances by sliding in the concrete transport tube (6). Thus, the front edge of the concrete (22) is not exposed to the air, and aggregate (24) in the concrete (22) stays in the plug flow region. Blockages are prevented.

Description

technical field [0001] The present invention relates to a prescribed appliance inserted into a concrete delivery pipe provided on a concrete pump truck or at a concrete pouring site, the present invention relates to an appliance which is not used before the start of concrete pressing The pre-mortar and pre-set chemicals required in the past are required. Background technique [0002] Concrete is produced at the mixing station by cement, sand, aggregate, etc., loaded in a mixer truck, and transported to the construction site. At the construction site, the concrete pump truck is waiting, and the concrete unloaded from the mixer truck is pressed to the required pouring site through the concrete pump truck. As known in the past, a concrete pump truck is composed of a self-propelled vehicle and various devices installed in the vehicle, namely, a hopper for pouring concrete, a concrete pump, a multi-section arm, a concrete delivery pipe supported on the arm, and the like. The ho...
