Description of the invention (1 [Technical Field] The present invention relates to a power front-mounted drilling device and a drilling method for drilling vertical holes in a formation, especially In the coiled hole drilling of the field-bound foundation sowing method, the power device required to drive the drill bit is an iron digging device and a drilling method provided close to the money head. [Technical background] For example, field drilling foundation pile construction method and other ground drilling operations In the field, it is often necessary to drill vertical holes in the ground. At present, in domestic and foreign field foundation pile construction methods, the methods of drilling vertical holes (hereinafter referred to as pile holes) are commonly used in reverse circulation method and full casing (Benoto) method. The isometry method is briefly described as follows. As shown in Fig. 1, the reverse circulation method firstly drills a short casing 10 on the ground surface, and then the short casing 10 is drilled into the formation to form a borehole H, which is drilled. The device is connected with a garlic-shaped drill bit 12 at the lower end of the hollow tubular drill pipe, and the upper end of the drill pipe 11 is supported by a rotary disk 13 provided on the ground, and the rotary disk is supplied by a nearby working machine 14 13 Required Power. A drill rod 15 connected to the drill rod n is connected above the turntable 13, and then the upper end of the drill rod 15 is suspended from the boom 16 through a rotary joint 15a and a cable unit i6a. A large-capacity suction is provided near the rotary disk 13. A pump 17 and a suction pipe 18a are connected between the upper end of the above-mentioned drill pipe 15 and the suction port of the suction pump 7. A multi-slot mud tank 19 'is also arranged near the construction site and connected to the suction by a row of mud pipes 19a. Between the discharge port of the suction pump 17 and the first tank 19b of the sinker 19, in addition, a sinker 19d is provided in the terminal tank 19c of the sinker 19 (the third tank in the figure). A circulating water pipe 19e is connected between the orifices (that is, inside the short sleeve 10). The paper size is applicable to the national standard (CNS) A4 specification (210 X 297 mm) 16029 ill -------- φ ^ ί ---- ^ — Order: (Please read the precautions on the back before filling this page) 522197 t A7 ------ ^ ——____ V. Description of the invention (2) (Please read the back (Please note that this page is to be filled in again.) During the construction of the reverse cycle method, the power of the work machine 14 is transmitted to the drill pipe U via the rotating disk 13 to rotate the drill pipe u and drive the drill bit 12 to rotate to the ground. At the same time, the submerged pump 19d is used to supply the clear water of the terminal tank 19c through the circulating water pipe 19e to the drilling h during the drilling, so that the sand and earth excavated by the drill bit 12 are rotated by the drill bit 12. The stirring effect becomes mud, so as to reduce the resistance to formation excavation, and to maintain the pressure in the hole of the borehole to prevent the hole wall from collapsing due to the pressure of the adjacent formation. On the other hand, the suction pump 17 is pumped through Suction pipe 18a, drill pipe 15, drill pipe π and the mud near the drill bit 12 is extracted, and then sent to the first tank 19b of the sinker 19 through the drain pipe 19a. Terminal slot 19c. However, 'the reverse circulation method will produce the following major defects: 1) The deeper the drill hole, the longer the drill rod 11, the weaker the torque transmitted by the work machine 14 to the drill bit 12, and the problem of the stiffness ratio of the drill rod will occur. . 2) Due to the digging effect of the drill bit 12 and the strong suction effect of the suction pump 17, a strong negative pressure effect will occur near the space where the drill bit 12 is located, and the amount of sludge extracted will increase, making the drilling diameter irregular, resulting in Broken hole. Printed by the Consumer Cooperative of the Ministry of Economic Affairs, ^ Hui Property Bureau. 3) Due to the drilling effect at the bottom of the borehole and the suction of mud paddles, the reverse circulating water introduced into the upper part of the borehole also flows quickly, resulting in unstable borehole walls. The susceptible collapse hole is missing, and the residual mud at the bottom of the induced borehole increases from time to time. 4) After the drilling operation is completed, a large amount of residual soil or silt is easily deposited at the bottom of the hole (several centimeters to several meters), and even after the concrete is poured, the concrete at the bottom of the pile contains sediment, which reduces the strength and bearing capacity of the pile. 5) It is impossible to extract large pebbles, and it is difficult to drill in hard formations. The paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 2 16029 522197 A7 V. Description of the invention (3) 6) The construction site needs to be equipped with a large-scale sedimentation tank 'to deal with a large amount of Shendian sludge and easily cause environmental protection problems, and it is difficult to set up a large-scale Shendian pond's space, which increases construction costs. In order to solve the above-mentioned shortcomings of the reverse circulation method, the so-called full casing (Benoto) method was developed. As shown in FIG. 2, the full casing method is a hollow casing 2 with a diameter of about b to 2 meters. Into the formation to be excavated to define and protect the borehole niches. The construction method is provided with a pipe shaker 21 having a stern arm 2u and a hydraulically pressed lower arm 21b. The sleeve 2q is held right by 挟 f 2U, and at the same time, the lower arm 21b is used to push the stern arm 21a downward to make the casing. Swirling downwards and pressing into the formation. Near the drilling site, a crane 22 for suspending a grab 23 is also available. At a predetermined depth in the above-mentioned casing 2G spinning waste formation, the grab bucket 23 is used to grab out the earth and stones in the casing 2G and transfer it to the nearby vermiculite truck (not shown) to take it away. After removing the soil and stones in the casing 20, place the steel cage (please refer to the symbol 8 in Figure 4 (e)), and use the special password (refer to the symbol 9 in Figure 4 (e)) from the bottom of the pile hole Start pouring concrete. After taking out, before the concrete is not solidified, the casing 20 is pulled out using the pipe shaker 21. This full casing method does solve the difficulties of the reverse circulation method, but it also creates new problems as described below. a) The casing 20 is screwed into the ground + sundial. It may be stuck due to excessive friction between the casing wall and the ground, or the concrete may be stuck for a long time when the concrete is irrigated. , Which seriously affects the construction progress. 16029 F 丨 This paper is suitable for China's broken ticket quasi-li printed by the Ministry of Economics and Intellectual Property Bureau's Consumer Cooperative ^ 22197 V. Description of the invention (4 b): The bucket 23 is inserted into the soil layer with the impact of a clip, and then it fails to engage Grab the earth and stones, so when the clips are clamped, there is still a large gap, and the earth and stones at the bottom of the hole cannot be completely and effectively removed. c) This method is to perform dry guarding within the casing 20, and the water inside and outside the casing M is not the same as the water pressure. When the concrete is poured, the bottom of the pile hole 被 is sealed by the concrete, which causes an unbalanced pressure between the inside and the outside of the casing, which causes the reinforced cage to float up due to the water pressure from the bottom of the casing when the concrete is poured. ) General Steel advised that the thickness of the cage compliance layer should be about 10 cm or less, but the thickness of the whole casing pipe wall was about 4 to 6 cm, and the gap between the steel cage and the casing 20 was only about 5 cm. Therefore, if the particle size of the concrete gradation is larger than 5 cm, the steel cage will engage with the casing and rise when the casing is pulled out. e) When the sleeve 20 is pulled out, the tube shaker 21 is used to make the sleeve 20 rotate about 45 degrees or 360 degrees. If the gap between the steel cage and the casing is too small, the steel rib cage may twist up with the casing 20 and even destroy the original steel dragon structure. > f) Since the bottom of the foundation pile hole is roughly located in the groundwater layer, a lot of groundwater and sand mud often flow out of the bottom of the pile hole in this method. This kind of mud and sand flowing out of the bottom of the hole cannot be ruled out, and the concrete has a floating effect in the early stage of concrete pouring, and even a hollow phenomenon (only mud and sand, no concrete) has completely lost the support point. g) The construction method has its construction restrictions. If the pile hole is too deep or the hole diameter is greater than 2 meters, no construction can be performed, and because of the need to install the pipe shaker 21 and related equipment, its construction is very limited by space, terrain and ground features.
