Two-liquid grouting device capable of arbitrarily adjusting angle of grouting pipe during surface drilling

Abstract

The invention discloses a two-liquid grouting device capable of arbitrarily adjusting the angle of a grouting pipe during surface drilling. The two-liquid grouting device is composed of a grouting pipe assembly, a flange pressing sleeve, a connecting sleeve, a flange sleeve joint and a drilling inner casing. The grouting pipe assembly communicates with the grouting pipe through a three-way pipe; the flange pressing sleeve is a pressing sleeve with one end connected with a flange; the connecting sleeve is a sleeve with the two ends connected with the flange, the sleeve wall is connected with agrouting branch pipe, and the grouting branch pipe communicates with the sleeve; the flange sleeve joint is a sleeve joint with one end connected with the flange; one end of the flange sleeve joint isconnected with the drilling inner casing, the other end of the flange sleeve joint is in flanged connection with one end of the connecting sleeve, and therefore internal channels of the drilling inner casing, the flange sleeve joint and the connecting sleeve communicate with each; the outer diameter of the pressing sleeve is not larger than the inner diameter of the sleeve, the inner diameter ofthe pressing sleeve is not smaller than the outer diameter of the grouting pipe, the pressing sleeve is sleeved with the connecting sleeve, the flange pressing sleeve is in flanged connection with theother end of the connecting sleeve, and the grouting pipe is sleeved with the channels for communicating the drilling inner casing, the flange sleeve joint and the connecting sleeve.

Description

technical field [0001] The invention belongs to the fields of water damage prevention and control in mines, municipal administrations, tunnels, etc., and relates to a double-liquid grouting device capable of arbitrarily adjusting the angle of a grouting pipe for ground drilling. Background technique [0002] The statements herein merely provide background information related to the present invention and may not necessarily constitute prior art. [0003] When using ground drilling to inject double-fluid slurry into deep formations to block water, due to the influence of the drilling tower and the drilling rig frame, a double-fluid grouting device is installed on the hole opening, especially when the grouting device is installed. The slurry pipe should be limited by the obstacles on the drilling tower, frame and foundation. In order to ensure that the operator can quickly install and disassemble the grouting device within the limited range of movement on the abutment, and to ...

Problems solved by technology

[0004] In order to effectively solve the problem that it is difficult to adjust the angle of the double-liquid grouting joint in the orifice mixing device during the double-liquid grouting in the ground borehole, it is difficult to install and disassemble, and sometimes it is forced to be in an unsafe position. On the one hand, the present invention provides a ground drill Two-liquid grouting device with holes that can adjust the angle of the grouting pipe arbitrarily
