Description
Technical Field
The invention relates to the field of pile foundation construction, in particular to a synchronous hammering integrated device for drilling and soil taking in a tubular pile in muddy soft soil.
Background
During the construction of the tubular pile in coastal sludge and soft silt land areas, the phenomena of displacement, inclination, sedimentation, uplift and the like of adjacent buildings, pipelines, roads and the constructed tubular pile are often caused by the soil squeezing problem, so that huge economic loss is caused; if the pile tip is used in pile sinking in a soft soil area, the soil squeezing effect is very serious; even if pile sinking is carried out without using pile tips, the problems of soil body uplift, crack generation of buildings, pipeline deformation, pile sinking deviation, floating and even pile breakage caused by insufficient dissipation of stress often occur.
At present, the engineering world often adopts methods such as stress release hole or leading hole earlier, and then hammering or static pressure construction solve this problem, arranges stress release hole or leading hole according to the monitoring data of structure horizontal displacement and vertical displacement usually, but the leading hole is got native and pile sinking can not be gone on simultaneously, causes silt, mucky soil body original state structure to suffer destruction easily, and the hidden danger that the soil body structural deformation brought can not be little worth.
Disclosure of Invention

The invention solves the problems and adopts the technical scheme that:
the utility model provides a synchronous hammering integrated device of drilling borrow in silt matter soft soil tubular pile, includes guide bar formula pile hammer, combination formula cylinder body, unit head and auger stem, slidable mounting has combination formula cylinder body on the guide arm of guide bar formula pile hammer, and the upper and lower both ends of combination formula cylinder body are connected with the diesel hammer plunger and the pile cap of guide bar formula pile hammer respectively, and unit head fixed mounting is in combination formula cylinder body, and the pile cap is hollow structure, and auger stem passes the pile cap and is connected with the unit head.
Compared with the prior art, the invention adopting the technical scheme has the outstanding characteristics that:
through the device, the pile can be synchronously sunk when the hole is led to fetch the soil, the disturbance to the soil body around the pile during pile sinking is avoided, the damage to the surrounding environment is reduced, the task of reinforcing construction of the existing building foundation is reduced, the construction period is shortened, the engineering cost is saved, and good economic benefit and social benefit can be created.

Detailed Description
The invention will be further illustrated by the following examples, which are intended only for a better understanding of the present invention and therefore do not limit the scope of the invention.
As shown in fig. 1 to 3, the integrated device for drilling and soil taking and synchronous hammering in the tubular pile in the sludge soft soil comprises a guide rod type pile hammer, a combined cylinder body 3, a power head 5 and a spiral drill rod 7, wherein the combined cylinder body 3 is slidably mounted on a guide rod 1 of the guide rod type pile hammer, the upper end and the lower end of the combined cylinder body 3 are respectively connected with a diesel hammer plunger 2 and a pile cap 4 of the guide rod type pile hammer, the power head 5 is fixedly mounted in the combined cylinder body 3, the pile cap 4 is of a hollow structure, and the spiral drill rod 7 penetrates through the pile cap 4 to be connected with the power head 5; the guide rod 1 is provided with a cable hole 8 for a cable to pass through, and the cable is connected with a power supply and then supplies power to the power head 5; the bottom of the combined cylinder body 3 is fixed with a flange 6, the upper end of the flange 6 is connected with the lower end of a power head 5, and the lower end of the power head is connected with a spiral drill rod through a smooth round drill rod 14 with the diameter of 100mm and the length of 300mm and a connecting screw thread 15; a clamp 13 for fixing the tubular pile 10 and a pile pad 12 are arranged in the pile cap 4; the tubular pile 10 adopts a small-diameter tubular pile with the diameter of 400mm-600 mm.
The specific application method of the device is as follows: firstly, according to the auger stem 7 of the length adaptation of tubular pile 10, fix tubular pile 10 on pile cap 4, wherein, the auger stem 7 of different diameter helical blade can be selected to tubular pile 10 of different stake footpaths, for example: when the diameter of the tubular pile is 300mm, selecting a spiral drill rod with a spiral blade of 190mm in diameter, when the diameter of the tubular pile is 400mm, selecting a spiral drill rod with a spiral blade of 230mm in diameter, and when the diameter of the tubular pile is 500mm, selecting a spiral drill rod with a spiral blade of 320mm in diameter; then, a crane hooks and fixes the cross top beam 9, lifts the device and the tubular pile 7, and moves the device to a correct pile sinking position; the diesel hammer cylinder body 11 drives the diesel hammer plunger 2 to hammer downwards, and meanwhile, the power head 5 drives the spiral drill rod 7 to rotate, so that the lower pile is hammered downwards and the hole is drilled; the device is periodically lifted by a crane, and soil in the tubular pile 10 is taken out through the spiral drill rod 7; then, fixing the next section of spiral drill rod 7 and the next section of tubular pile 10, and repeating the steps until all the tubular piles 10 are sunk; when the first section of tubular pile 10 is sunk, the spiral drill rod 7 selects the perforated spiral drill rod, the length of the perforated spiral drill rod is 1m shorter than that of the first section of tubular pile 10, the spiral drill rod 7 is additionally arranged during pile splicing to select the standard spiral drill rod, and the length of each standard spiral drill rod is equal to that of the tubular pile 10 which is constructed synchronously.
This device, simple structure, convenient to use for hammering, guiding hole and dumping can go on in step, and pile sinking speed is fast, and is efficient, to the disturbance of the pile week soil body when having reduced pile sinking, has reduced the destruction to the surrounding environment, has also reduced the task to existing building foundation reinforcement construction simultaneously, has shortened construction period, has practiced thrift engineering cost, can create good economic benefits and social.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, which is defined in the appended claims.
