Abstract
The utility model relates to a waterproof sleeve for an anchor rod. The waterproof sleeve comprises a straight steel sleeve and is characterized in that a water-stopping steel fin ring is welded on the straight steel sleeve; and water swelling rubber strips are arranged at a water facing side of a welding face and at the lower end of the straight steel sleeve. The wall thickness of the straight steel sleeve is more than 5 mm, the length of the straight steel sleeve is more than 150 mm, and an external diameter of the straight steel sleeve is the same as the diameter of the rock anchor rod; the wall thickness of the water-stopping steel fin ring is more than 4 mm, and the width of the water-stopping steel fin ring is 70-80 mm; and the water-stopping steel fin ring is welded on the straight steel sleeve through a fillet weld. According to the waterproof sleeve provided by the utility model, the waterproof detects at the connection node of the rock anchor rod and a main structure can be effectively improved by lengthening and blocking an underground water seepage path, so that the waterproof sleeve has very good values in utilization and popularization.
Description
Technical field
The utility model relates to the rock soil anchor accessory, specifically a kind of anchor pole waterproof sleeve that is used for the resistance to plucking rock soil anchor.
Background technology
Because construction convenient and efficient and resistance to plucking effect are obvious, rock soil anchor is widely used in the construction of underground structure as a kind of effective resistance to plucking measure.Existing rock soil anchor end moulding form adopts single straight shaped steel sleeve usually.Because material is different; Steel and concrete interface very easily form the seepage action of ground water path; Traditional straight shaped steel sleeve makes that again this percolation path is too short; Hide some dangers for for underground water infiltrates structure, this becomes the weak link of underground structure waterproof with regard to the connected node that causes rock soil anchor and agent structure.
Summary of the invention
The purpose of the utility model is to provide a kind of anchor pole waterproof sleeve; It has the function in lengthening and blocking groundwater seepage path; Can effectively improve the waterproof defective of rock soil anchor and agent structure connected node, also can strengthen the anchorage effect of anchor pole in agent structure simultaneously.
To achieve these goals; The technical scheme of the utility model is: a kind of anchor pole waterproof sleeve; Comprise shaped steel sleeve always, it is characterized in that on this straight shaped steel sleeve welding sealing steel wing ring, the water-swellable adhesive tape is set in the meet water lower end of side and this straight shaped steel sleeve of solder side.
The utility model discloses welding sealing steel wing ring on straight shaped steel sleeve, meet water side and steel bushing lower end (being the side that meets water of steel bushing and concrete surface) of solder side the water-swellable adhesive tape is set simultaneously.Wherein, straight shaped steel sleeve has the function of anchor pole top slurries moulding form; Sealing wing ring can play the effect in effective lengthening seepage action of ground water path, has also strengthened the anchorage effect of anchor pole in agent structure simultaneously; And the deformable when meeting the underground water infiltration of water-swellable adhesive tape is expanded, and can play blocking effect definitely to the underground water percolation path.
Description of drawings
Fig. 1 is the schematic perspective view of the utility model one embodiment.
Fig. 2 is the sectional drawing of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
The utility model is welding sealing steel wing ring 2 on straight shaped steel sleeve 1, meet water side and steel bushing lower end (being the side that meets water of steel bushing and concrete surface) of solder side water-swellable adhesive tape 3 is set simultaneously, and the new waterproof sleeve is promptly formed in above-mentioned measure.According to the preferred embodiment of the utility model, straight shaped steel sleeve 1 wall thickness＞5mm, length＞150mm, external diameter are with the rock soil anchor diameter; Sealing steel wing ring 2 wall thickness＞4mm, radial width are 70 ~ 80mm; Sealing steel wing ring is welded on the straight shaped steel sleeve through fillet weld 4, and the solder side side (being sealing steel wing ring and the weld of straight shaped steel sleeve below) that meets water is provided with the water-swellable adhesive tape; Steel bushing lower end (being the side that meets water of steel bushing and concrete surface) is provided with the water-swellable adhesive tape.Before the slip casting of resistance to plucking rock soil anchor pore-forming, in this waterproof sleeve segment insertion hole, part is exposed on the top mark height of hole.Wherein, straight shaped steel sleeve has the function of anchor pole top slurries moulding form, and the wide sealing wing ring of the 70～80mm underground water that then extended effectively infiltrates the percolation path of structure, has also strengthened the anchorage effect of anchor pole in agent structure simultaneously.And be arranged at steel bushing lower end (being the side that meets water of steel bushing and concrete surface) and steel solder side meet water side the water-swellable adhesive tape meet underground water when infiltrating deformable expand; Reduce the slit of steel and concrete interface, promptly can play blocking effect definitely the underground water percolation path.In sum, this new waterproof sleeve can effectively improve the waterproof defective of rock soil anchor and agent structure connected node, also can strengthen the anchorage effect of anchor pole in agent structure simultaneously, has good use value and promotional value.
