Sleeve valve pipe and grouting construction method comprising same
The invention relates to the technical field of anchoring engineering, and discloses a sleeve valve pipe. The sleeve valve pipe comprises a guide pipe assembly and a sleeve valve pipe body, wherein the guide pipe assembly comprises a pipe body and an end cover which are made of rigid materials, the bottom end of the end cover is a sharp end, the top end of the end cover detachably covers the bottom end of the pipe body, the sleeve valve pipe body is arranged in the pipe body, and the pipe body and the sleeve valve pipe body can slide relatively. Based on the structure, when the sleeve valve pipe is inserted into a grouting hole, the guide pipe assembly plays a role in guiding the sleeve valve pipe body to the bottom of the grouting hole, and the pipe body and the end cover which are made of rigid materials are high in strength, so that the sleeve valve pipe is more easily inserted into a soil body, the perpendicularity deviation can be reduced, and particularly, the sleeve valve pipe can be easily inserted into a soil body with large water content and various soft layers; and the guide pipe assembly further plays a role in protecting the sleeve valve pipe body, deformation of the sleeve valve pipe body due to the fact that the soil body extrudes the sleeve valve pipe body is prevented, and the quality and effect of foundation reinforcement are guaranteed. In addition, the invention further discloses a grouting construction method comprising the sleeve valve pipe.
本发明涉及锚固工程技术领域，公开了一种袖阀管，其包括导向管组件和袖阀管本体，导向管组件包括由刚性材料制成的管体和端盖，端盖的底端为尖端，其顶端可拆卸地盖设于管体的底端，袖阀管本体设于管体内，管体和袖阀管本体之间可相对滑动。基于上述结构，将袖阀管插入注浆孔中时，导向管组件起到了将袖阀管本体引送至注浆孔底部的作用，由刚性材料制成的管体和端盖强度较大，使其更易于插入土体并能减小垂直度的偏差，尤其是易于插入含水量较大、软弱层种类较多的土体，导向管组件还起到了保护袖阀管本体的作用，防止土体挤压袖阀管本体导致其变形，保证地基加固的质量和效果。另外，本发明还公开了一种包括袖阀管的注浆施工方法。
