Description

Large-scale long auger drilling that shakes

Technical Field

The utility model belongs to the technical field of machinery, concretely relates to long auger drilling of large-scale vibrations.

Background

The drilling machine is widely used for drilling of prospecting, railways, highways, bridges, water conservancy and hydropower, tunnels, wells, anchor rods, small-caliber diamond core wire coring drilling, industrial and civil construction, engineering geological exploration, ground source hot drilling, coal bed gas drilling, outburst prevention drilling machines and the like, and along with the development of the times, the engineering design requirements of the existing pile foundation are increased and the geological conditions are more and more complicated. The difficulty of pile foundation construction is increased. In the case of many complex geological structures among many pile foundation equipments, some problems exist in that existing pile foundation equipments are still not able to solve many difficulties in the engineering well. And a lot of construction difficulty and economic cost are added to construction units.

At present, the most widely used pile foundation drilling machine is used in engineering, and the first type is a hole forming construction process of a rotary drilling machine. However, in most engineering projects, a large amount of water and slurry are needed for the rotary drilling rig, a large amount of slurry can be produced on site, so that a lot of difficulties are caused to the construction site, for example, on-site water shortage, too much slurry on site, inconvenience in walking of other vehicles, personnel and equipment, and troubles and cost are increased for the production and outward transportation of the slurry. In the past, the process of forming holes by using mud to protect walls is mature and widely applied. However, the construction process is opposite to the environment-friendly process advocated by the national government at present, so that the construction unit is very difficult. The rotary drilling rig is also often subjected to a plurality of hole collapse conditions (hole forming is difficult, and mud protective walls cannot be well solved), such as thick quicksand, mucky soil, backfill soil, large boulder and the like in the stratum. The rotary excavating construction needs measures such as steel pile casings under a vibration hammer, construction cost is increased, concrete consumption is increased (filling coefficient of concrete is increased), and construction progress is slowed down. And a more complex geological structure is formed, and the hole forming of the rotary drilling equipment is more difficult. If foundation soil has various (multi-layer) soil structures and an interlayer (a lens body), one layer of soil is soft, the other layer of soil is hard (or compact), the other layer of soft soil is provided, but a pile body must penetrate through the lens body according to the specification and the design requirement (the design and the specification require that a 3D range cannot have a soft layer), a steel casing is required to be arranged in the soft soil layer, and the hard (compact) soil layer is difficult to penetrate through the steel casing during construction. Great construction difficulty and economic cost are often added to construction units and construction units. In another situation, the rotary drilling needs slurry to protect the wall and form a hole, but foundation soil has a large number of cracks, slurry needs to leak during hole forming, the slurry leaks instantly when a drilling machine just drills the cracks, then the drill hole is backfilled, and the hole is drilled again, so that the hole forming is difficult and concrete is wasted.

The second pile foundation equipment is an impact hole-forming drilling machine, a large amount of slurry is also needed, the slurry is troublesome to manufacture and transport outside, and the slurry is more difficult to transport outside particularly in urban construction. And the construction efficiency is very low, and the construction process is also very old. The construction progress can not meet the requirement of the construction period and can not meet the requirement of the times. Many construction units and designs are reluctant to adopt this construction process.

The third pile foundation equipment is a long spiral drilling machine and a vibration pipe sinking drilling machine, the existing long spiral pile machine has many advantages, but the range of the pile capable of being constructed is too small, only small and medium-sized pile foundations can be constructed, the pile diameter is generally within 800mm, and the pile diameter is rarely more than 800 mm. The pile diameter of the vibration immersed tube drilling machine cannot exceed 600 mm. The reason is that the movement is too small, the construction process is too old, and the capability of drilling complicated rock and soil is limited.

Therefore, a new pile foundation device is needed to solve the above existing problems at the same time.
