Description
Technical field
The invention belongs to soft soil foundation field, specially a kind of foundation driller that can establish lathe ground on the ground in weak soil
And method.
Background technology
Heavy machine tool is widely used in fields such as the machinery in China, space flight, national defence, the energy, is China's equipment
The representative product of manufacturing industry.But one of the subject matter that presently, there are of domestic heavy machine tool is precisely due to heavy machine
The huge quality of bed volume is very big, and ground is difficult the requirement for meeting lathe load-bearing, and the ground in especially many areas is partially soft, in order that
Obtaining heavy machine tool at work can be steady, generally requires to carry out consolidation process to ground, such as Chinese patent CN103469783A
" a kind of soft soil foundation reinforcing method ", the reinforcement means use weak soil compacting equipment, and the weak soil compacting equipment includes：Nip drum
Machine and two sets of rail pressure devices；The reinforcement means comprises the following steps：A drafts of soft soil foundation is determined first；Set
Four fixed foundation points；The nip drum machine is arranged on compacting initial position；Make the front stretching of two sets of rail pressure devices respectively
Mechanism and rear telescoping mechanism alternating movement, the nip drum machine accordingly move forward and backward, so as to be compacted to the soft soil foundation,
Until actual drafts meets the requirement of overall reduction.And for example Chinese patent CN1957143A " reinforcement means of soft soil foundation ",
In the inside of the ground of consolidated subsoil periphery, vertical drainage part is set, forms vertical row supply passageway, is supplied in the vertical row
The inside of path, the water with sealing part is poured into, by above-mentioned vertical supply passageway, the water with sealing part is supplied to reinforcing
The inside of the ground of ground periphery, the sealing part being circulated into above-mentioned vertical supply passageway are spread in vertical confession with current
To the periphery of path, sealing region is formed, its effect is：The sealing region formed by sealing part hinders consolidated subsoil periphery
Ground inside underground water movement, the consolidated subsoil periphery of the forced drainage of underground water with consolidated subsoil can be suppressed
The decline of the underground water of the inside of the ground in portion, it can effectively suppress the consolidated subsoil periphery of the reinforcing of adjoint soft soil foundation
The sedimentation of ground.
The above method is to soft soil foundation repair and then establish after firm ground the fixation for carrying out lathe, and it is applied
Work amount is big, and program is complex, and labour cost is higher, and the ground established is unable to antidetonation resistance to compression, and service life is short.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention provides a kind of self tapping ground that can establish lathe ground on the ground in weak soil
Stake and method, it can be done directly on the foundation that weak soil carries out lathe ground on the ground, reduces construction volume and human cost.
To realize above-mentioned technical purpose, the specific technical scheme that the present invention takes is that one kind can be established on the ground in weak soil
The foundation driller of lathe ground, the foundation driller are included with the rotation base portion of screw thread, cylinder, the first resistance part, the
Two resistance parts and the 3rd resistance part, cylinder is successively by base portion and the first resistance part, the second resistance part, the series connection of the 3rd resistance part
Together, and the first resistance part, the second resistance part and the 3rd resistance part are respectively positioned on base portion and rotate screw thread rotation opposite direction
Side, and have 0.25-0.5m spacing between resistance part and resistance part；First resistance part, the second resistance part, the 3rd resistance part
Size increase successively, and the size of the first resistance part with base portion rotate screw thread external diameter it is consistent
Wherein, the foundation driller is prepared using high-strength structure material.
Another object of the present invention is to provide a kind of method that lathe ground is established using foundation driller, including it is as follows
Step：
A, the base portion of foundation driller is rotatably inserted into weak soil ground, until base portion acts on the external force of the gravity such as lathe
Under can not continue deeper into；
B, the weak soil below resistance part is dug out, and the mixture of the weak soil dug out and expanding cement, water is poured；
Wherein the volume ratio of expanding cement, mud soil and water is 3：2：0.5；After casting complete, using the roll-in with lathe with tonnage
Wheel rolls to pouring position, then repeats cast and rolling, until the uppermost resistance part of casting area and self tapping ground
Upper surface be in same level；
C, the installation of lathe can be carried out after standing one week.
As the improved technical scheme of the present invention, the expanding cement includes the material of following parts by weight, gypsum 10-15
Part, swelling agent 10-14 parts, retarder 13-18 parts, ceramic particle 30-80 parts, clay 15-20 parts, slag 15-30 parts.
As the improved technical scheme of the present invention, the average grain diameter of the ceramic particle is 3-10mm.

Beneficial effect
The foundation driller that the present invention uses carries base portion and resistance part, base portion can self tapping rotation go deep into weak soil ground,
After basal end is submerged in weak soil completely, resistance part can also be goed deep into weak soil in the drive lower part of base portion, by under resistance part
The weak soil of side digs out and uses the mixing of weak soil and expanding cement, water to be poured, the mixture meeting of weak soil and expanding cement, water
Blending solidification is carried out with the weak soil on foundation driller periphery, finally self tapping ground dress is fixed；Simultaneously as resistance part face
Product is larger, when being under pressure, first, pressure can disperse；Second, the lower section of resistance part comes from filler to its support force so that
Foundation driller can bear higher impulsive force during lathe use, without sinking.
