The self drilling anchor bolt of foundation support applied for buildings

The self drilling anchor bolt of foundation support applied for other buildings or streets around the foundation pit, deep foundation pit or the poor soil stability conditions.Self drilling anchor bolt through the friction of its soil and soil pressure on the bolt, and if necessary, also anchor pipe can be added when necessary for stronger support to deal with a large area of soft soil layer.

Deep roadway excavation of rock mass, rock mass under complicated environment of high temperature, high stress, high water pressure .There is great change in the deep surrounding rock geological mechanics environment, so the mechanical characteristics of deep roadway surrounding rock has its peculiar.

Self drilling anchor bolt support as a way of supporting, and there is a fundamental difference in traditional way of support.Traditional way of supporting is often caused by passive collapsed rock mass under loading, but anchor bolt supporting can actively strengthening rock and soil body, effectively control the deformation, prevents the occurrence of collapse.The main function of  self drilling anchor bolt supporting is suspensory action, cut across function, and the roles of composite beams and extrusion strengthening effect.

The self drilling anchor bolt of foundation support applied for other buildings or streets around the foundation pit, deep foundation pit or the poor soil stability conditions.Self drilling anchor bolt through the friction of  its soil and soil pressure on the bolt, and if necessary, also anchor pipe can be added when necessary for stronger support to deal with a large area of soft soil layer. For foundation support, anchor supporting has flexible, economic and easy to operate, safe and fast these features.And in the process of the installation of the self drilling anchor bolt, which won't generate a lot of noise and strict with construction site, even if it also can complete the set up in the narrow space.

To ensure that the anchor Angle, slope protection pile length, pile diameter, pile body strength, the strength of self drilling anchor bolt, slump, anchor length, ratio of cement slurry, grouting pressure can meet the requirements of design, such as pile length and pile vertical error will be limited within a range, to ensure that the correct concrete label.Also, to ensure that bolt does not collapse before pouring, ensure that the diameter of the hole of self drilling anchor bolt has certain requirements and reinforcement placement locator when brace.
