Abstract
The utility model provides a self tapping recyclable deep foundation pit anchor rod which can be broadly applied to the anchoring and timbering the foundation pits of a common clay layer and a high level soft soil layer; the utility model mainly comprises a connection disc, the tail part joint of the anchor rod, a rod body, an extension welding piece, a middle joint, a bush joint, a front end joint, a front end anchor rod, and a front end aiguille; the tail part joint of the anchor rod is provided with a screw thread; the outsides of the rod body, the bush joint, and the front end anchor rod are surrounded by a deformed triangle steel wire to form a spiral shape; and the aiguille is welded on the front end anchor rod. The anchor rod has the main advantages of: 1, directly screwing the anchor rod into a soil layer without drilling in advance and needing not to use the technical means like filling cement and an anchor rod agent and the like to carry out anchoring treatment, thus extensively improving the construction speed and the construction efficiency; 2, being capable of generating large pulling intensity by using a larger screw height to be spirally screwed into the soil, thus improving the construction safety; 3, being capable of reusing the product after screwing out the product after the construction is accomplished, thus saving the material, reducing the construction cost, and avoiding the problem to generate environment pollution.
Description
Technical field
This product belongs to the mechanical ﹠ electrical technology field, the recyclable deep foundation ditch anchor pole of specifically a kind of self tapping.
Background technology
Soil nailing (claiming anchor pole again) supporting is a kind of new support technology that is used for pattern foundation pit supporting structure and stability of slope, and since producing the seventies, because investment is low, construction speed is fast, and technology is simple, has obtained in the world using widely.China begins in base pit engineering to use the plate brad supporting technology the beginning of the nineties, flourish along with China's subway construction, the safety problem of Deep Foundation Pit of Metro Stations excavation and the influence of surrounding enviroment is more and more caused people's great attention.In the deep-foundation pit engineering design, key problem is a supporting and protection structure design and construction problem, and along with the continuous development of theoretical and engineering practice, supporting and protection structure design theory and job practices have also obtained continuous perfect.Over more than 10 year, many units have carried out number of research projects around the working mechanism of plate brad supporting, design and calculation method, construction technology etc., obtained the achievement of many uniquenesses, plate brad supporting has obtained applying rapidly throughout the country, and its application is progressively expanded to the weak soil layer area of high water level by general cohesive soil stratum.The recyclable deep foundation ditch anchor pole invention of self tapping is a technical products scheme that works out in the process of research Xi'an subway foundation pit supporting, through constantly correction, field trial and technical testing, has reached the support technology designing requirement.
Summary of the invention
The utility model provides a kind of self tapping recyclable deep foundation ditch anchor pole, can be widely used in general argillic horizon and high water level weak soil layer foundation ditch anchoring support.
The utility model is achieved in that the recyclable deep foundation ditch anchor pole of a kind of self tapping, mainly contain terminal pad, anchor pole afterbody joint, the body of rod, extension bar soldering member, transition joint, casing joint, front tab, front end anchor pole, front end drill bit composition, anchor pole afterbody joint is provided with screw thread, the body of rod, casing joint, front end anchor pole wind outward with special-shaped triangle steel wire, form spiral-shapedly, drill bit is welded on the front end anchor pole.
The beneficial effects of the utility model are: 1, need not hole in advance, directly anchor pole be screwed in the soil layer, the technological means such as mud and anchor pole agent of need not pouring water are carried out the anchoring processing, significantly improve speed of application, improve efficiency of construction.2, can produce bigger pull strength because of screwing in the soil, improve working security with the bigger high spiral of silk.3, after construction is finished, reuse after this product can being screwed out, saved material, reduced construction cost, avoid producing problem of environmental pollution.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure 1, terminal pad 2, anchor pole afterbody joint 3, the body of rod 4, extension bar soldering member 5, transition joint 6, casing joint 7, front tab 8, front end anchor pole 9, front end drill bit form
The specific embodiment
Be described further below in conjunction with accompanying drawing: the utility model is mainly used in deep foundation pit support, when construction, uses the rig of high-torque hydraulic motor that this anchor pole is screwed in soil, reinforces together with foundation ditch cement pile with nut again; Dark below 6 meters the time when the needs anchor, optional one directly screws in the soil, as when crossing 6 meters, the way of available connector prolongs rock-bolt length, the lengthening anchor pole degree of depth, and after construction finished, available rig screwed out anchor pole.
