  • the inner casing of the movable body the former mainly uses the drill pipe or the reaction torque Balance the mechanism to deliver torque.
  • the reason why it is called activity is to use the elasticity of the steel plate. It can be opened or contracted. After a small water pipe is passed through the round hole of the special buckle, it becomes a casing.
  • ⁇
  • a well-sealed fixed outer casing It is mainly used in conjunction with the movable inner casing. Suitable for particularly complex formations and water operations.
  • Chuck (Fig. 9 - Fig. 10): The inner and outer casings designed by the pile driver are not threaded. Because of the large diameter, it is not easy to implement and the processing is difficult. At the same time, if the entire thickness of the casing is increased, it will increase its own weight, let alone the elastic bending of the casing. Therefore, only the thin steel plate is used to make the casing main body, and then the ribs are welded on the outer side of the rib. The larger the diameter, the larger the ribs should be, and the six pieces are symmetrically welded here. Then, at the appropriate position on the upper and lower parts of each rib, some transverse grooves are opened, and these grooves are used to solve the problem of their joint and hanging weight.
  • the chuck here is designed to solve these problems: it can either engage or loosen the casing or hang the full weight. In addition, it can simultaneously press in or pull out the double sleeve.
  • Casing support (Fig. 8): This is the supporting equipment of this patent, which is specially designed for hanging inner and outer casings. The structure is simple and easy to operate. It is hung from the lower part of the general drill and can be rotated freely. The figure is omitted because of the length relationship, that is, a chain (254) should be added between the two hook rings (195) - see Figure 13, the length is more than 2.5 times the length of each tube.
  • Hole retainer and inner sleeve hook (Fig. 12-Fig. 13): For personal safety, the hole must be protected by a retainer. But here is not just for this purpose, there are other 'uses. As mentioned above, after the inner sleeve is shrunk, its diameter and the distance from the inner wall of the outer sleeve are not strictly regulated, which brings certain difficulties to lifting. In order to solve this problem, here, on the top ring beam of the orifice retainer, six hooks are suspended by a chain. The middle shaft of the hook can be rotated freely, and there is a baffle on the front.
  • Water pipes and cable guides (Fig. 14): The water pipes of the former submersible pile machines are hung with hooks. It is convenient to lift them in a short distance, but it is much more difficult to make long and long distance lifting.
  • This patent is designed with a hose winch.
  • the former has a cable winch.
  • water pipes and cable guides are designed here. Its function has two aspects. First, when the pile driver is lowered into the hole, the winch and the hoist are braked, and the guide will automatically flip over, aligning the center of the hole, and at the same time, they can automatically slide down the pile machine. Second, when the pile driver is lifting and unloading, the cable winch and the water pipe must be lifted.
  • Water pipe anti-rotation device (upper part of Fig. 5): The pile driver can not rotate in the casing, and can only slide up and down along the guiding groove. In the process of reeling, the water pipe hoisting machine will rotate the water pipe itself at a certain angle. This will definitely break the water pipe. In order to solve this problem, a water pipe anti-rotation device is added to the upper part of the rushing pile driver. The action of the upper and lower parts is separated mainly by the friction of the bearing and the sealing ring.
  • Drilling and expanding the drill bit (Fig. 15): There are a variety of drill-drilling drill bits for the former pile driver, which are of the upper and lower type. However, the simpler ones are for single reaming, and they cannot be used for positive or negative circulation. Drilling and expanding is more complicated, even with hydraulic control. It is very inconvenient for the tubing to pass through the well. Therefore, I have made some improvements to the drills of the predecessors here.
  • the upper grounding seat is fixed on the upper part of the center tube, the lower hinge seat is movable, and the moving distance is limited by the hexagonal sleeve, so that the most wood reaming or contraction state can be obtained.
  • Both the drilling and the bottoming fins can be removed, and the holes can be drilled or reamed separately, or drilled and reamed at the same time, and positive and reverse circulation can be performed.
  • it cannot be used alone and must be combined with a pile driver to be used.
  • an inverted three-leg reaming basket is added to the lower part of the drill bit, which is bolted to the drilling fin holder.
  • Impact pumping 2-in-1 drill bit (Fig. 16):
  • the above mentioned rushing drill mainframe also has impact function, but it is not the main one. It is only suitable for use in some relatively soft and stable formations. It is not suitable for loose, gravel-bearing formations and hard bedrock. Therefore, a drill bit that combines the impact and the suction pump is designed here. As long as it is a relatively stable formation that does not require casing, it can be drilled, whether it is soft or hard.
  • the shape is somewhat like a cross-shaped drill bit, but it differs greatly in structure.
  • a bucket is welded on the upper part of the cross blade, and four flaps are arranged on the bottom. Four vent pipes are welded in the bucket near the center tube.
  • a burr is welded to the outer edge of the blade, which forms a large and small annular space between the hopper (separated by a thick steel plate in the middle).
  • Hand-cranked or electric water pipe winch (Fig. 17): The textbook “Modern Foundation Engineering Construction” refers to the water pipe roller, but the structure is unclear, even if it is someone else's patent. However, the water pipes of the former pile driver are all hung with hooks, and it is not suitable for retracting with rollers. So here I designed a water pipe hoist that can be hand-cranked or motor-driven. The purpose is to roll the high-pressure pipe on the reel, which can be retracted at any time, saving labor. However, the reel is rotating, and the suction and drain pipes leading to the pump or pool are not rotatable.
  • an anti-rotation device must be added to the shaft row and the outer end of the inlet pipe in the reel, and the flushing liquid discharged or discharged is continuously communicated with the bottom of the hole through the elbow and the high-pressure pipe.
  • the driven reel can be driven directly by the V-belt pulley, but the speed cannot be too high, and the converted current must be input into the motor.
  • This design also needs to solve some other problems. If the deeper the hole is drilled, the more the number of high pressure pipe rolls rolled in the drum, the lower the line speed of the outer layer and the inner layer. do not. The problem of the drop of the high-pressure pipe is still solved. If it is difficult to make it rise synchronously with the wire rope, I am afraid that it will add more equipment.
  • Manpower collection and drain pipe platform (Fig. 11):
  • the hose winch designed above has advantages, but it also has disadvantages.
  • the advantages are as follows: First, to ensure that the flushing fluid can be continuously pumped or transported during the drilling process; secondly, the high-pressure pipe can be automatically slid down following the pile driver; thirdly, during the lifting process of the high-pressure pipe, No matter the hand or the motor, it saves labor.
  • the main disadvantages are as follows: First, it is difficult to control the synchronization process of the high-pressure pipe and the wire rope during the lifting process. Second, when the reverse circulation is drilled, a large amount of gravel fragments flow in the curved pipe for a long distance, which is bound to accelerate.
  • the manpower retractable water pipe platform is designed. On this platform, the water will be flat and flat in the shape of "8". First, its radius is increased, and the rinsing fluid with sediment and gravel flows on the same level, which is easy to pass. At the same time, the water pipes are curled one by one, and the angles they twisted cancel each other out, which eliminates the twisting phenomenon and prolongs the use of 'life. But its disadvantage is that it increases the physical labor intensity. In fact, the cable can also be retracted in this way, much simpler. ' "
  • the lower roller switch of the discharge tower funnel (Fig. 18): The unloading tower and the funnel used in this pile driver are basically the same as the previous ones. The difference is that there is a discharge tower retainer on the upper part of the funnel. There are eight movable plates at the bottom of the retainer, which are basically the same as the movable blocks in the chuck box. The diameter can be increased or decreased within a certain range.
  • the pile driver can be freely lowered and can be placed on the shoulder of the outside of the hanging cylinder to remove the waste. In order to save space, no drawings are drawn. However, the switches in the lower part of the funnel of the predecessors I feel that it is not suitable for the use of this pile driver.
  • the board switch which is pushable with a lever; it is also bolted. It is most suitable for some clays and fine homogeneous materials, but not for some uneven sizes of stones, especially large stones.
  • the cement slurry mixing plant on the modern construction site is hydraulically driven to open and close the loose leaf. This requires a larger motor and hydraulic pump, which is reliable, but increases engineering costs. Therefore, I am here to design another roller switch. Take two short seamless tubes, cut half of them in the middle, leaving a small part at both ends. Then they are made to roll relative to each other along the circumferential surface. When the part is turned to the cut part, the crack appears, and the switch is opened.
  • the two cylindrical surfaces are in contact with each other, and only the relative rolling is performed.
  • the switch is off. If one of the rollers on the right side is rotated clockwise, the two rollers are always lifted up and open, so that all cuttings and stones can not be blocked, and their rotation.
  • the invention patent has a total of eighteen figures, which are not so much. Because the whole pile machine is large in size and complicated at the same time, if the proportion is too small, it will not be clear.

  • the outer layer continuously pulls the cuttings away from the center. From the surface depth gauge, it can be seen that when the pile machine descends to the bottom of the hole, if there is a wreckage, if it is lowered by 180, the wing bit has been opened to the maximum, and it is slightly inclined outward. However, the right (29), middle (18), and left (30) welds on the outside are vertical, so the drilled holes are also vertical.
  • the fin bit will be opened to the maximum when the depth gauge is lowered by 180 X 2 mm.
  • the theory is like this, it is actually difficult to master in the work. In general, after seeing a 180mm drop on the depth gauge, you should drill a little more, and you should stop drilling until it can't fall any more. At this time, the hole bottom of the drilled hole is not flat. It cuts the rock roughly along the ⁇ -track in the lower part of Fig. 1 or Fig. 2, and can be described by a simple image. Some are like a volcanic cone, and slowly rise from the hole wall to the middle. There is a hole in the center.
  • the motor When the direction of the current after the frequency conversion is changed, the motor will drive the central shaft tube to rotate counterclockwise, and the fin bit will follow in turn. Since the splicing member (30) on the left side does not protrude from the outer edge of the flap, it is also wedge-shaped when viewed from the horizontal and vertical directions, but its chamfered surface is inclined inward. So when the fin is reversing, it creates a pressure that shrinks inwardly due to the presence of the medium, but it does not necessarily make it close. Only when the fin drill is reversed, the weight is controlled on the scale (the upper part is not rotated, or slightly larger), and the pile driver is slowly raised within the range of 180 mm on the depth gauge.
