Grouting device for high coagulation grouting material

Abstract

The invention relates to the field of grouting, in particular to a grouting device for highly condensable grouting materials. It includes a grouting pipe, a connecting head and a self-sealing pipe head. One end of the connecting head is connected to the grouting pump through the grouting pipe, and the other end of the connecting head is connected to the self-sealing pipe head through the grouting pipe. The grouting pipe is connected to the connecting head, The self-sealing pipe heads are all fixed and sealed connections. It is easy to install, the connection between the grouting pipe and the connector and the self-sealing pipe head is reliable, and can be reused; because the inner diameter of the connector is consistent with the inner diameter of the grouting pipe and the grout outlet on the end cap of the self-sealing pipe head is a circular grout The mouth effectively reduces the pressure loss during the grouting process, and the grouting effect is good.

Description

technical field [0001] The invention relates to the field of grouting, in particular to a grouting device for highly condensable grouting materials. Background technique [0002] With the development of grouting technology, new high coagulation grouting materials are continuously used in anchor cable construction, but the new materials have the problems of high viscosity, poor flow, and fast coagulation speed. If they are not cleaned in time after grouting, it is easy to Blocking the pipeline will affect the grouting effect. It is difficult to ensure the cleaning effect by using one-stage grouting pipeline, so it is recommended to use segmented pipeline, each section length is 4-5m. There are currently two commonly used connection methods for the joint position of segmented pipelines. One is casing connection and iron wire binding, which is difficult to guarantee the effect when the grouting pressure is high; the other is commercial joint connection, which can effectively e...

There are currently two commonly used connection methods for the joint position of segmented pipelines. One is casing connection and iron wire binding, which is difficult to guarantee the effect when the grouting pressure is high; the other is commercial joint connection, which can effectively ensure the connection effect , but the installation is time-consuming and laborious, and it is easy to cause the diameter of the grouting pipe to change and be damaged

The end of the grouting pipe is reserved at the end of the anchor cable to ensure the smooth flow of the pipeline and prevent impurities from clogging the grouting pipe when the anchor cable is installed. The pipe head is generally sealed with tape. When grouting, rely on the grouting pressure to break the tape, and it cannot be repeated. In addition, when using the grouting pipe for grouting, the grout surface is spherical, and there is a pressure loss during the flow of the grout, resulting in limited grouting effect
