Embodiment Construction

[0013] see figure 1 and figure 2 , the present invention includes a grouting pipe 2, a cone head 1 and a joint 5, the grouting port of the grouting pipe 2 is connected to the joint 5 through a thread, the grouting pipe outlet is connected to the cone head 1 through a thread, and the grouting pipe 2 is arranged at the bottom Hole 9, the grouting holes are provided with multiple layers, the grouting holes in each layer are evenly distributed, and the layers are arranged in a staggered manner. The key technology is that the grouting hole 9 is a threaded hole, and the grouting hole 9 is threaded to install the grouting heads 7 with different inner diameters, the aperture of the grouting hole can be selected, or the grouting hole 9 is threaded to install a plug Head 8 seals the grouting holes, so as to select the location and quantity of the grouting holes according to the needs of grouting.

[0014] A reinforcing sleeve 6 is installed at the root of the grouting pipe 2 .

Abstract

The invention discloses an adjustable plug-in slurry injector, and belongs to a slurry injector in the filed of distorted concrete slurry injection construction. The adjustable plug-in slurry injector comprises a slurry injection pipe, a conical head and a connector, wherein a slurry inlet of the slurry injection pipe is connected with the connector, a slurry outlet of the slurry injection pipe is connected with the conical head, slurry injection holes are formed at the lower portion of the slurry injection pipe and are arranged into a plurality of layers, the slurry injection holes of each layer are distributed evenly, and the layers are arranged in a staggered mode. The adjustable plug-in slurry injector is characterized in that the slurry injection holes are threaded holes, slurry outlet heads of different inner diameters are arranged on the slurry injection holes, or plugs are arranged on the slurry injection holes. The adjustable plug-in slurry injector has the advantages that the slurry injection holes are the threaded holes, the slurry outlet heads of different inner diameters are arranged on the slurry injection holes, and the hole diameters of the slurry injection holes can be adjusted as needed. The plugs are arranged on the slurry injection holes, the height and the quantity of the slurry injection holes can be adjusted as needed, the hole diameters of the slurry injection holes can be adjusted freely, so that distorted concrete slurry is injected conveniently and evenly, and construction quality is guaranteed.

Description

technical field [0001] An adjustable plug-in grouting device belongs to a grouting device in the field of metamorphic concrete grouting construction. Background technique [0002] At present, in hydropower construction projects, surface grouting or slotting grouting is mostly used for adding grout to metamorphic concrete. There are problems of uneven grouting, waste of grout, and slow natural penetration of grout on the surface, and the construction quality is difficult to guarantee. Patent No. 2003201103356 discloses a grouting device, which includes a long polypropylene tube, on which a slurry outlet hole and a slurry outlet head are arranged, and a joint is provided at the end of the long polypropylene tube, and a plug can be installed on the joint head. The grouting device is used for one-time grouting during coal mine roadway maintenance, and cannot be reused for grouting metamorphic concrete in hydropower construction projects, and the height, quantity and aperture of...
