Abstract
The utility model relates to a supporting protection anchor rod for preventing soil walls from collapsing, comprising a tubular rod body and a taper-shaped tip head fixed on the front end of the tubular rod body. The outer wall of the tubular rod body is provided with a plurality of agnail-shaped anchoring wing sheets. The main body of the tubular rod body under the agnail-shaped anchoring wing sheets is provided with a mud jacking hole penetrating through the inner and the outer walls of the rod body. The external force is used to strike the anchor rod into the soil walls. Pressure cement mud is poured into the soil walls through the tail end of the anchor rod exposed out of the soil walls to penetrate into the anchored soil layer through the mud jacking hole, and the anchor rod and the soil layer are solidified together for acting an anchoring supporting protection effect. The utility model avoids drilling operation, and is especially suitable for the anchoring supporting protection to the soft soil layer with the hole-forming difficulty.
Description
The utility model relates to the support anchor rod that a kind of Tu Bi of preventing caves in.
In the excavation of foundation pit supporting of civil works, bolt support structure that the stability of slope processing operation adopts often, must hole on side slope or Tu Bi with the rotary impact rig earlier, and then implantation reinforced anchor bolt, grout injection is solidified as a whole reinforced anchor bolt and desire fixing soil again, to improve the shear strength of soil, prevent that Tu Bi from collapsing.The deficiency of this employing reinforced anchor bolt mode is in broken grounds such as some common miscellaneous fills, sand, very easily collapse in the hole that rig breaks into, even bore not pore-forming at all, influence the perfusion of the implantation of reinforcing bar and cement paste and make and stablize the supporting operation quality and be difficult to guarantee.
The purpose of this utility model be overcome the above-mentioned deficiency of prior art and provide a kind of need not into the tubular type mud jacking of implanting the special punching of anchor pole from the anchor soil bolt.
The purpose of this utility model is achieved through the following technical solutions: the tubular type mud jacking is from the anchor soil bolt, comprise that a tubulose shaft and is fixed in the taper tip of this tubulose shaft front end, the outer wall of tubulose shaft is provided with some reversed acanthoid anchor tab, has the mud jacking hole that runs through the inside and outside wall of tubulose shaft on the tubular rod shaft body below the reversed acanthoid anchor tab.Using external force during use inserts in the native wall anchor pole to requiring anchorage depth, press water mud is then by being exposed at outward that the outer anchor pole tail end of Tu Bi pours into the inner chamber of tubulose shaft and the mud jacking hole offered penetrates into and desires in the consolidated soil on tubulose shaft body, reach the anchoring of vertical foundation pit retaining wall, guarantee its stability.The anchor tab available angle steel of reversed acanthoid is done, and increases the anchored force of anchor pole in soil except that playing, and squeezes at anchor pole and also plays the protection unlikely effect of being stopped up by soil in mud jacking hole in the soil layer process.What, alternate distance of its distribution are decided by the situation of the supporting Tu Bi of institute.The quantity in mud jacking hole can corresponding setting with anchor tab, also can be less than anchor tab.
The utility model project organization is reasonable, and processing and fabricating is easy and with low cost; Omitted the drilling operation in the existing bolt support operation simultaneously, operation simplification, efficient are improved.Be particularly suitable for the anchoring support of the broken ground of some pore-forming difficulties.
Further specify the utility model below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model
As shown in Figure 1, formation of the present utility model comprises tubulose shaft 1, taper tip 2, reversed acanthoid anchor tab 3 and mud jacking hole 4.Tubulose shaft 1 can be the welded steel pipe making of 50mm with diameter, also can select for use the steel pipe of other diameter and wall thickness to process according to anti-earth lateral pressure and anchored force needs; Taper tip 2 can be that the II grade reinforcing steel of 20～25mm is forged or lathe grinding processes through heat with diameter, is welded on the front end of tubulose shaft 1.The situation of anchoring soil layer is along the alternate certain distance setting of all directions of tube wall on demand in mud jacking hole 4, and reversed acanthoid anchor tab 3 available angle steels are done, and is welded on the tubulose shaft outer wall and protects in the top in mud jacking hole 4.The size of angle steel section and length can resistance to plucking anchored force on request be determined.
Claims (2)
1, the tubular type mud jacking is from the anchor soil bolt, it is characterized in that described tubular type mud jacking comprises that from the anchor soil bolt tubulose shaft and is fixed in the taper tip of this tubulose shaft front end, the outer wall of tubulose shaft is provided with some reversed acanthoid anchor tab, has the mud jacking hole that runs through the inside and outside wall of tubulose shaft on the tubulose shaft body below the reversed acanthoid anchor tab.
2, tubular type mud jacking as claimed in claim 1 is characterized in that from the anchor soil bolt described reversed acanthoid anchor tab is made of the angle steel that is welded on the tubulose shaft outer wall.
