具体实施方式detailed description

下面结合附图对本实用新型作进一步详细的说明。Below in conjunction with accompanying drawing, the utility model is described in further detail.

如图1、2所示,本实用新型包括充气孔1、充气管2及爪型钢管4。所述充气孔1设置在充气管2的上端,充气管的下端与爪型钢管4链接。As shown in Figures 1 and 2, the utility model includes an air charging hole 1, an air charging pipe 2 and a claw-shaped steel pipe 4. The inflation hole 1 is arranged on the upper end of the inflation pipe 2, and the lower end of the inflation pipe is connected with the claw-shaped steel pipe 4.

如图3、4所示,所述的爪型钢管4包括三根支钢管42和一根竖直钢管41,三支钢管42分别与竖直钢管41的底端焊接而成,支钢管42与竖直钢管41连通,且支钢管42与竖直钢管41之间具有锐角夹角。爪型钢管4的支钢管的端部通过钢环7固定安装有橡胶套3,橡胶套3内支钢管42的侧壁上设有多个气孔6。As shown in Figures 3 and 4, the claw-shaped steel pipe 4 includes three steel pipes 42 and a vertical steel pipe 41. The three steel pipes 42 are welded to the bottom of the vertical steel pipe 41 respectively. The straight steel pipes 41 are connected, and there is an acute angle between the branch steel pipes 42 and the vertical steel pipes 41 . The end of the supporting steel pipe of claw-shaped steel pipe 4 is fixedly installed with rubber sleeve 3 by steel ring 7, and the side wall of supporting steel pipe 42 in rubber sleeve 3 is provided with a plurality of air holes 6.

本实用新型的工作原理为:三根支钢管42焊接在爪型钢管4的竖直钢管41的下端,由于其向上翘起一定角度,支钢管42斜向上插入土体中,节省了空间,易将其打入土中,方便施工。当从充气孔1处充入气体后,流经充气管2到达爪型钢管4并流向支钢管42的端部,使橡胶套3充气胀大成鼓腰状,橡胶套3胀大之后挤压周围土体,使之产生挤压变形,而土体压缩变形后拥有较大的应力,其作用在橡胶模3上,可得到较大的锚固力,从而锚固作用更好。当充气完毕后撤掉充气管2,向爪型钢管4内高压注浆,这样就实现了本实用新型的锚固作用。The working principle of the utility model is: three supporting steel pipes 42 are welded on the lower end of the vertical steel pipe 41 of the claw-shaped steel pipe 4, because they are tilted up at a certain angle, the supporting steel pipes 42 are inserted into the soil obliquely upward, which saves space and is easy to install It is driven into the soil to facilitate construction. After the gas is filled from the inflation hole 1, it flows through the inflation pipe 2 to the claw-shaped steel pipe 4 and flows to the end of the support steel pipe 42, so that the rubber sleeve 3 is inflated into a bulging shape, and the rubber sleeve 3 is squeezed around after expanding. The soil mass is squeezed and deformed, and the soil mass has greater stress after being compressed and deformed, which acts on the rubber mold 3 to obtain a greater anchoring force, so that the anchoring effect is better. Remove the inflation pipe 2 after the inflation is completed, and high-pressure grouting in the claw-shaped steel pipe 4, so that the anchoring effect of the present utility model has been realized.

本实用新型操作更为简单,施工方便,锚杆节省空间,打入土体充气注浆后即可提供全部的锚固力,无需加固软土地基,锚固效果更好,且对环境无污染,可重复利用更环保。The utility model is simpler to operate, more convenient to construct, and the anchor rod saves space. It can provide all the anchoring force after being injected into the soil and injects air. It does not need to strengthen the soft soil foundation, and the anchoring effect is better. Reuse is more environmentally friendly.
