The characteristics of the solid and strong anchor how technology and innovation
Abstrac:
Anchor characteristics:Shell bolting is hollow in the slope、Geotechnical surface engineering of deep foundation pit, and the tunnel、Of the men in the stope underground cavern construction such as a way of reinforcement。With metal parts、Wood pieces、Polymer or other material rod string,Into the surface of the rock mass or cavern surrounding rock mass in the drilled hole in advance,Use their head、The special structure of the rod body and tail plate(Also don't have to),Or depends on the bonding together and stability of rock mass surrounding rock and suspension effect、The effect of composite beams、Reinforcing effect,In order to achieve the purpose of supporting。With low cost、The supporting effect is good、Easy to operate、Using flexible、Construction is clear
The introduction of hollow grouting anchor function
Abstrac:
Hollow grouting anchor determination of anchoring force is one of the tools,With small volume、Light weight、Easy to carry、The operation is simple、Safety etc. Characteristics,Hollow grouting anchor is widely applied in coal、National defense、Tunnel and transportation, and other operation of the tunnel;Hollow grouting anchor rod is suitable for the geological conditions of medium,The permanent support and support in advance。Hollow grouting anchor rod through the hollow rod body for pressure grouting bolt,Can achieve consolidation and broken rock mass,Partition the groundwater and the purpose of the rod body corrosion,Can rapidly form a supporting force,Control the stability of surrounding rock。①Hollow design,Realized the function of grouting。②When grouting is full,You can achieve it
Bolt of technical knowledge
Abstrac:
Anchor(Also known as the soil anchor、Soil nailing)Is in natural soil side wall of the borehole、In the tension member、Grouting anchor formation。The tie rod according to the use of different materials,Can be divided into coarse steel bar、High strength steel wire bundle、Steel wire, etc。The side wall anchor area、The layer number、Spacing、Through the calculate and determine the length, etc。 The hole diameter should be determined by the design。Hole grouting is commonly used, which has two kinds of cement mortar and concrete,Should be selected by design,Determine the mixture ratio and strength level,More commonly used cement mortar grouting。Drilling should be downward sloping15°~35°Angle,The concrete determined by design。Hole grouting can be full fill,Also can only fill in the bottom of the hole must be anchored
