Description
The utility model relates to the project building construction instrument, particularly a kind of drilling tool manually that uses in engineering construction building site bracing of foundation pit, roadbed side slope reinforcing, soil nailing drilling construction.
At present, be widely used in generally adopting in the aspects such as building site bracing of foundation pit, roadbed side slope reinforcing roof-bolter boring.We know, in building operations, anchor pole is a kind of tension member of using in the capital works excavation, as Chinese patent CN94108778.6 number disclosed " special drilling machine of large-head anchor rod construction method and use thereof ", the one end is connected with engineering foundation ditch retaining wall, the other end is anchored in the underground soil layer, to bear soil layer or water pressure to the thrust that retaining wall causes, keeps the stability of soil layer or building.The processing step of existing anchor rod construction method is: 1, hole to projected depth with auger; 2, put into the steel trombone slide that the next door is fixed with the Grouting Pipe of plastic pipe or steel pipe; 3, by the Grouting Pipe grout injection of plastic pipe or steel pipe, generally need perfusion three times and health.The anchor pole of constructing like this is because of the frictional force between anchor pole and the undisturbed soil reduces, and the pulling capacity of bearing is low.In order to improve anti-pulling of anchor bar, need to increase the quantity and the length of anchor pole, brought great difficulty to construction, increased operating expenses, delayed programming.In recent years, along with highrise building, the Deep Foundation Excavation engineering progressively increases, and basic retaining wall is more and more higher, and the anchor pole pulling capacity of making of existing job practices is lower, does not satisfy design requirement far away.For this reason, people adopt the long anchor pole that steel hinge rope is made more.Though this long anchor pole anchored force is bigger, complex process, constructional difficulties, because the geology soil layer changes greatly, and anchored force can not scale up with the increase of pull bar length, although rock-bolt length increases much sometimes, anchored force increases very little simultaneously.In addition, even more important a bit is the restriction that this technology is subjected to the operation place, promptly the operation site condition is required height, and relocation equipment displacement difficulty is prone to mechanical breakdown, incurs loss through delay the duration, engineering cost cost height, and the power etc. that wastes energy.
The purpose of this utility model is: the problem design that exists at prior art provides a kind of simple in structure, and maneuverability is applicable to various complicated difficult site conditions, and rapidly and efficiently, cost is low, the hand-operated tools of reliable quality engineering construction boring.
The utility model is achieved by following manner: a kind of hand-operated tools of engineering construction boring, it is characterized in that forming by drill bit and drilling rod two parts, wherein, bit part is the hollow shovel 1 of a semi-cylindrical shaped, the front end and the back side at the hollow shovel 1 of semi-cylindrical shaped are respectively equipped with the cutting edge 6 and the tube bridge of the nose 2, back at the hollow shovel 1 of semi-cylindrical shaped then partly is connected with drilling rod, the said connection here can be welding, riveted joint or other are conveniently detachable fixedly connected etc., as Fig. 1,2, shown in 3, the hollow shovel 1 of the said semi-cylindrical shaped in front removes the part after half and at its front end and the back side cutting edge 6 and a tube bridge of the nose 2 is set respectively for hollow cylindrical, wherein cutting edge 6 can be 45 ° of gradients, can certainly according to circumstances be designed to other angle, as 30 ° (or between 30 °-45 °) or the like, and the end of cutting edge 6 is straight, sometimes also can be designed to circular arc, be similar to the circular shape of spade front end.In addition, one that the tube bridge of the nose 2 provides in figure, two or more that also can uniform setting, the shape of the tube bridge of the nose 2 also is circular (or circular arc), just its radius is big (and thickness is less) than the radius of the hollow shovel 1 of semi-cylindrical shaped, is convenient to operation (as creep into and fetch earth) etc. like this in the engineering construction.The drilling rod part is made up of action bars handle 3, extension bar 5 and the joint pipe collar 4 of the two, as shown in Figure 1, 2, 3, here drilling rod partly is by increasing the length that joint pipe collar 4 and extension bar 5 come the extension arm part by the intensification of construction drilling depth, be generally hole depth at 2-30 meters, drilling diameter becomes orifice angle at 0-90 ° at 80-200 millimeters.
The important technological parameters of the drill bit of present technique, drilling rod part is: 100-300 millimeters of the length of the hollow shovel 1 of the semi-cylindrical shaped of bit part, diameter is 60-280 millimeters, wall thickness is 4-10 millimeters, the gradient of cutting edge 6 is 30 °-45 °, the tube bridge of the nose 2 wide 15-30 millimeters is apart from 20-40 millimeters of front end cutting edge distances.19-50 millimeters of the action bars handle 3 of drilling rod part and extension bar 5 diameters, 2-5 millimeters of wall thickness, 1-9 meters of single-unit length (two ends cover external screw thread), the internal diameter of joint pipe collar 4 internal thread that matches with the drilling rod external diameter, 3.5-4.5 millimeters of wall thickness, 30-80 millimeters of length.See Table 1 according to the situation of change that becomes the corresponding boring bar tool technical data of hole size variation in the concrete construction
