The utility model is used for the long-spiral drilling machine of shaping long spire hole-expanding pile, is provided with stopping means, the maximum angle that described stopping means is opened for limiting reaming valve between wherein said drilling pipe and reaming valve.
The long-spiral drilling machine difference from prior art that the utility model is used for shaping long spire hole-expanding pile is that the utility model installs drilling pipe for the long-spiral drilling machine of shaping long spire hole-expanding pile in drilling rod outside, reaming valve is installed bottom drilling pipe, reaming valve is closed when drilling pipe reversely rotates, incision soil layer is opened when rotating forward, be rotated in soil layer by drilling pipe and dig cannelure, the native slag dug enters in drilling pipe, utilizes the helical blade on drilling rod to take native slag out of ground.This device structure is simple, low cost of manufacture, convenient operation, and can disposable pile, and efficiency of construction is higher.
Below in conjunction with accompanying drawing, the long-spiral drilling machine for shaping long spire hole-expanding pile of the present utility model and piling method are described further.
Accompanying drawing explanation
Fig. 1 is the structural representation of long spire hole-expanding pile;
Fig. 2 is the structural representation of the utility model for the long-spiral drilling machine of shaping long spire hole-expanding pile;
Fig. 3 is the structural representation of the utility model for drilling pipe in the long-spiral drilling machine of shaping long spire hole-expanding pile.
Detailed description of the invention
As shown in Figure 2, the utility model comprises the first unit head 1, drilling rod 2, drill bit 3, drilling pipe 6 and the second unit head 7 for the long-spiral drilling machine of shaping long spire hole-expanding pile.Output and the drilling rod 2 of the first unit head 1 are in transmission connection, and drilling rod 2 outside is with helical blade 4, and drill bit 3 is arranged on drilling rod 2 lower end, drill bit 3 offers concrete valve 5, and drilling rod 2 is connected with concrete pumping plant by pipeline.Drilling pipe 6 and drilling rod 2 are coaxially arranged, and drilling pipe 6 internal diameter is slightly larger than the external diameter of drilling rod 2 external helicoid blade 4, and drilling pipe 6 is enclosed within drilling rod outside and is positioned at below the first unit head 1.Shown in composition graphs 3, bottom drilling pipe 6, barrel offers through hole, and through hole hole wall is provided with the jointed shaft 8 with drilling pipe 6 axis being parallel, jointed shaft 8 is connected with reaming valve 9, the shape of reaming valve 9 is identical with through hole, and reaming valve 9 is positioned at above drill bit 3.Between drilling pipe 6 and reaming valve 9, stopping means is installed, the maximum angle that stopping means is opened for limiting reaming valve 9, stopping means can adopt block, be resisted against the maximum angle that reaming valve 9 outside is opened to limit it, in the present embodiment, the radius of drilling pipe 6 is 200mm, reaming valve 9 open after maximum radius be 400mm.Output and the drilling pipe 6 of the second unit head 7 are in transmission connection, and the second unit head 7 is arranged on the mast of long-spiral drilling machine.
The formation of pile of the utility model long-spiral drilling machine is adopted to describe as follows:
A, long-spiral drilling machine is erected at construction point, starts the first unit head 1 and the second unit head 7, drive drilling rod 2 and drilling pipe 6 synchronously to creep into downwards, in downward drilling process, drilling rod 2 rotates forward, and drilling pipe 6 reversely rotates, and the native slag in stake holes is taken out of ground by helical blade 4.
B, creep into desired depth position when drill bit 3, close the first unit head 1 and the second unit head 7, open the concrete valve 5 on drill bit 3, start concrete pumping plant concrete to be sent in drilling rod 2, concrete injects in stake holes by concrete valve 5, start lifting appliance, make drilling rod 2 and drilling pipe 6 upwards Synchronous lifting, the stake holes below drill bit 3 is filled up by concrete.
C, when reaming valve 9 is promoted to the position corresponding with setting reaming section, close lifting appliance, start the second unit head 7, drilling pipe 6 is driven to rotate forward, reaming valve 9 with the effect of soil layer frictional force under open and cut in the middle of soil layer, reaming valve 9 is rotated in soil layer the cannelure digging and be positioned at above drill bit 3 along with drilling pipe 6, and native slag is entered in drilling pipe 6 by through hole.Then start the second unit head 7, drive drilling pipe 6 to reversely rotate and reaming valve 9 is closed, start the first unit head 1, drive drilling rod 2 to rotate forward, helical blade 4 takes native slag out of ground.
D, startup lifting appliance, make drilling rod 2 and drilling pipe 6 continue upwards to promote, concrete is injected in cannelure by concrete valve 5 and forms reaming pile cutoff.
E, when reaming valve 9 be promoted to set the corresponding position of reaming section with the next one time, repeat step C and step D, until drill bit 3 and drilling rod 2 leave ground completely, close concrete pumping plant, namely form long spire hole-expanding pile as shown in Figure 1.
