Definitions
- Injection tube for injecting media particularly suitable for rock solidification which essentially consists of a tube which can be inserted into a borehole and is provided with a borehole closure and a check valve.
- the injection lances consist of pipe sections which can be connected to one another via sleeves and each have a connection for the trailing lines of a two-component synthetic resin, for example, and a check valve in the deepest hole at the ends facing the mouth of the borehole.
- a mechanically actuated borehole closure is provided in sections in an injection pipe via sleeves.
- the mechanical borehole closure is expanded by rotating the injection pipe until it bears against the borehole wall.
- Anchors are often used to stabilize the mountains. Their use with cartridges is particularly useful when the mountains are broken up great difficulties, which essentially consist in the fact that the cartridges often cannot be inserted into the borehole. In such cases, full bonding of the anchor cannot be guaranteed.
- the invention is based on the object of combining rock consolidation by injection with the additional stabilization of the rock by an anchor effect in a labor-saving and economical manner.
- the tube is designed as an anchor rod with a thread rolled onto the end located outside the borehole, that a check valve is arranged in the injection head and a rupture disk is arranged at the end of the anchor rod directed to the borehole, and that the borehole closure is as an inflatable hose section surrounding the anchor rod and held at the ends by bindings is formed with a check valve integrated between the anchor rod and the inflation chamber.
- the injection pipe designed as an anchor rod
- the injection pipe is inserted into a borehole in the appropriate design, based on the wall thickness and the corresponding steel, to the extent that the so-called hydraulic inflatable packer is located in the region of the borehole mouth.
- the required injection pressure is applied to the anchor rod.
- the rupture disc functioning as a check valve at the end of the anchor rod causes such a high back pressure to form within the anchor rod that the check valve provided between the anchor rod and the inflation chamber of the borehole closure first opens and the inflation process begins. This check valve prevents the pressure from relaxing after sealing Borehole closure when the rupture disc breaks and the injection medium escapes into the borehole.
- the entire borehole is filled above the borehole closure.
- the injection tube designed as an anchor rod is completely glued after the injection agent has hardened.
- the rupture disc serving as a check valve can be adapted to the requirements of the mountains, dimensioned to different bursting pressures and also arranged in the anchor rod behind the borehole closure. In addition to the outlet at the end of the anchor rod, this can be provided with additional outlet openings over its length.
- the check valve according to the known principle of a bicycle valve should have at least one opening in the anchor rod, which is sealed off from the inflation space by a flexible sleeve.
- a flexible sleeve In order to achieve a faster blowing effect and thus filling the blowing space, it has proven to be advantageous to provide a plurality of openings in the anchor rod distributed over the circumference which are covered by a common sleeve.
- the injection tube attached in this way provides an injection anchor that can be approved as an expansion part with a defined support force.
- the injection tube is made of simple steel and provided with a cut thread as an effective injection tube that is not approved as an anchor, contains an anchor comparable effect and in this way represents an inexpensive removal agent with a high expansion effect.
- the particular advantage of the anchor rod according to the invention is that, in addition to a reliable injection with a secure borehole seal, a high level of compensation for the rock is achieved by simultaneous anchoring against high injection pressures. In contrast to the injection alone, a predictable load capacity is introduced into the mountains, which depends on the load capacity of the injection tube. Depends on the anchor tube and results from the stiffening of the anchored layers and the dowelling of broken layers on solid layers.
