The utility model discloses limitation (rectifying the effect slow in the face of vertical circular port, the building is because the deep soil body disturbance of drilling is probably too inclining greatly), behind basic one side traditional pore-forming instrument becomes the circular port, become to rectify to dip by taking two or more pore-forming devices again and draw the soil hole, the disturbance basement soil body makes the basis produce to subside and then realize that existing building rectifies. Vertical area is rectified and is drawn native hole pore-forming device can realize drawing native fast, controllable subsides, accurate rectifying, vertical drilling construction more the horizontal hole construction convenient, rectifies for existing building and provides new thinking.

Description

Pore-forming device with soil hole capable of rectifying inclination

Technical Field

The utility model relates to a slope building technical field who rectifies inclines especially rectifies and draws pore-forming device in soil hole.

Background

After years of theoretical research and engineering practice, the technical field of building inclination correction is greatly developed at home and abroad, and the reason for generating the building inclination is deeply known. According to the building inclination correction technology, the method can be summarized into five categories of forced landing method, lifting method, reservation method, transverse loading method, comprehensive method and the like according to the principle. Most building inclination is caused by uneven settlement of soil at the bottom of a foundation, so that the inclination correction method of the soil digging forced landing method has a wide application range.

Under most circumstances, draw native rectification and rely on engineering experience to go on, however when the ground soil body is better, draw the hole of native and often be difficult to smoothly realize drawing the soil, or draw the earth after the building can not realize anticipated rectification effect, be unfavorable for realizing that the building is controllable, accurate rectification, probably lead to rectifying failure or produce higher rectification reinforcement cost.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is: the utility model provides a take one kind to rectify and draw pore-forming device in soil hole, the soil hole of drawing that this pore-forming device formed can realize easily that the building is controllable, accurate rectifying.

The utility model provides a technical scheme that above-mentioned technical problem adopted is:

A pore-forming device with a soil hole for rectifying and digging comprises a cylinder, wherein a lug boss is arranged on the outer side wall of the cylinder.

In the above scheme, the top end of the boss is sharp.

In the scheme, the upper end of the cylinder is provided with a connecting rod used for being connected with a drilling machine.

in the scheme, the upper end of the cylinder is provided with the end enclosure, the connecting rod is connected with the end enclosure, and the end enclosure is provided with the air hole.

The utility model discloses limitation (rectifying the effect slow in the face of vertical circular port, the building is because the deep soil body disturbance of drilling is probably too inclining greatly), behind basic one side traditional pore-forming instrument becomes the circular port, become to rectify to dip by taking two or more pore-forming devices again and draw the soil hole, the disturbance basement soil body makes the basis produce to subside and then realize that existing building rectifies. Vertical area is rectified and is drawn native hole pore-forming device can realize drawing native fast, controllable subsides, accurate rectifying, vertical drilling construction more the horizontal hole construction convenient, rectifies for existing building and provides new thinking.

The beneficial effects of the utility model are that:

1. take the pore-forming device that the soil hole was drawn in to the flower rectifying can form in the basement soil body to take the flower rectifying to draw the soil hole, for traditional circular port, the foundation soil body is disturbed more easily, takes the flower rectifying to draw the soil hole and produce the deformation more easily under the basement pressure effect, arouses the basis to subside, effectively solves vertical rectifying to draw the soil hole and rectify a difficult problem unmovable.

2. The soil body under the base can only form in the less degree of depth soil body under the base and take the soil hole of rectifying in the pore-forming device, cuts under the effect of soil in-process basement pressure, and the soil body around the hole begins the foundation that warp promptly and subsides, realizes existing slope building rectification, is favorable to realizing the controllable rectification of building.

3. The pore-forming device who draws soil hole is rectified to flower is according to the different specifications of drilling equipment commonly used, designs out the pore-forming device that takes that is suitable for different apertures, the standardized construction of being convenient for, and the reuse device is high-efficient economy.

4. The area is rectified to incline and is drawn the existing slope building in-process of pore-forming device of soil opening, can be simultaneously at a basic side drill into a plurality of circular ports, carries out area flower pore-forming disturbance basement soil body to partial circular port, can monitor the limit construction simultaneously, avoids producing suddenly heavy, cross heavy.

Detailed Description

The embodiment of the utility model provides a as shown in fig. 1, 2, it includes drum 4, and drum 4 is hollow thick steel pipe, is equipped with boss 5 on the lateral wall of drum 4, the top of boss 5 is sharp-pointed, the upper end of drum 4 is equipped with connecting rod 1 that is used for being connected with the rig.

The upper end of the cylinder 4 is provided with a seal head 3, the connecting rod 1 is connected with the seal head 3, and the seal head 3 is provided with an air hole 2.

Ordinary rectifying is drawn the soil hole and is dug the back, changes the rig drill bit into the utility model discloses take the two pore-forming devices that rectify and draw the soil hole, connecting rod 1 and rig articulate. As shown in fig. 3 and 4, the hole forming device with the vertical soil hole having the inclination correction function is placed inside the vertical circular soil hole, and under the constraint of the hollow thick steel pipe, the drill rod of the drilling machine is lifted and placed to enable the hole forming device with the vertical soil hole having the inclination correction function to vertically move along the axial direction of the circular soil hole, and a soil body is cut through the boss 5 (the polished short steel bar). In the soil cutting process, as the hollow thick steel pipe and the circular soil digging hole have similar diameters, in the process of downwards cutting soil by the pore-forming device, the formed air pressure can be released through the air pressure exhaust air hole 2, and the soil cutting is ensured to be smoothly carried out. Reciprocating in this way, the pore-forming device can form a vertical soil correcting and digging hole 6 with flowers.

In the soil body cutting process of the hole forming device with the soil correcting and digging holes, the soil body around the soil digging holes deforms under the action of the base pressure, and the foundation 7 is further settled.

The utility model discloses pore-forming device draws soil hole rectifying effect for promoting rectifying and provides new thinking. The device provides the pore-forming device who is applicable to circular different apertures such as digging native hole aperture 100 to 200mm, can realize taking the vertical pore-forming effect of rectifying and digging the native hole of flower, and effective disturbance basement soil body realizes digging fast, accurate controllable rectifying's rectifying effect of rectifying. Simultaneously, this utility model designs the pore-forming device who is suitable for different apertures according to drilling equipment specification commonly used, the standardized construction of being convenient for, and repeated recycle device, economic benefits is better.

It should be understood that the vertical rectifying soil hole with the strips can be more conveniently applied to pile foundation rectifying engineering. Modifications and variations are possible to those skilled in the art in light of the above teachings, and all such modifications and variations are intended to be included within the scope of the present invention as defined in the appended claims.
