Abstract
The invention belongs to the field of soft-soil foundation construction, and specifically relates to an anti-fracture machine tool base. The machine tool base is prepared from mixed cement, which comprises the following substances in parts by weight: 50 to 60 parts of high strength cement, 15 to 20 parts of hydroxyl polyurethane, 20 to 30 parts of quartz stone, 10 to 15 parts of calcium oxide, 7 to 9 parts of acetic acid-1-naphthyl ester, and 15 to 20 parts of 1-naphthylacetic acid. The machine tool base can effectively buffer the direct impact on base so as to prevent collapse or fracture due to long-term impact.
Description
Technical field
The invention belongs to soft soil foundation construction field, a kind of anti-fracture lathe ground.
Background technology
Heavy machine tool is widely used in fields such as the machinery of China, space flight, national defence, the energy, is China's equipment
The product that manufacturing industry is representative.But, one of subject matter that domestic heavy machine tool presently, there are is precisely due to heavy machine
The huge quality of bed volume is very big, and ground is difficult to meet the requirement of lathe load-bearing, and the ground in especially a lot of areas is the softest, large scale computer
Bed in use can occur significantly to shake, and sinking of ground the most even can occur.
So that heavy machine tool at work can be steady, generally require and ground is carried out consolidation process, as China is special
Profit CN103469783A " a kind of soft soil foundation reinforcing method ", described reinforcement means uses weak soil compacting equipment, described weak soil pressure
Real equipment includes: nip drum machine and two set rail pressure devices；Described reinforcement means comprises the steps: first to determine soft soil foundation
Drafts；Four basic points regularly are set；Described nip drum machine is arranged on compacting initial position；Make described two set rails respectively
The front stretching mechanism of pressure device and rear telescoping mechanism alternating movement, described nip drum machine seesaws accordingly, thus to described soft
Soil base is compacted, until actual drafts meets the requirement of overall reduction.And for example Chinese patent CN1957143A " weak soil ground
The reinforcement means of base ", in the inside of the ground of consolidated subsoil periphery, vertical drainage part is set, forms vertical row supply passageway,
In the inside of this vertical row supply passageway, pour into the water with sealing part, by above-mentioned vertical supply passageway, will have sealing part
Water be supplied to the inside of ground of consolidated subsoil periphery, be circulated into the sealing part in above-mentioned vertical supply passageway with current
And it is spread in the periphery of vertical supply passageway, and forming sealing region, its effect is: the sealing region formed by sealing part is hindered
The movement of the subsoil water of the inside of the ground of consolidated subsoil periphery, can suppress the forced drainage of the subsoil water along with consolidated subsoil
The decline of subsoil water of inside of ground of consolidated subsoil periphery, can effectively suppress adding of the reinforcing with soft soil foundation
Gu the sedimentation of the ground of ground periphery.
Said method is all to be compacted soft soil foundation or the firm ground of drain reinforcing method foundation, and it is great in constructing amount,
Program is complex, and labour cost is higher, and the ground set up can not antidetonation resistance to compression, and easy fracture, service life is short.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of anti-fracture lathe ground, and it is for lathe ground capital construction
If time, can effectively buffer the direct impulsive force of lathe base over the ground, it is to avoid ground gene is hit for a long time and subsides or rupture
Situation.
For realizing above-mentioned technical purpose, the concrete technological means that the present invention takes is: a kind of anti-fracture lathe ground,
Described lathe ground uses blended cement to be prepared from water 3:1 by volume, and described blended cement includes following weight portion
Each material:
High strength cement 50-60 part,
Hydroxyl polyurethane 15-20 part,
Quartz 20-30 part,
Calcium oxide 10-15 part,
Acetic acid-1-naphthalene ester 7-9 part,
1-naphthalene acetic acid 15-20 part,
Condensing agent 8-10 part.
As the technical scheme of the improvement of the present invention, also include characteristic water reducer 5-10 part.
As the technical scheme of the improvement of the present invention, the particle size of quartz is 5mm-1cm.
As the technical scheme of the improvement of the present invention, high strength cement includes each material of following weight portion:
Quartz sand 15-30 part,
Cinder 10-15 part,
Calcium silicates 10-29 part,
Even sandstone 10-20 part,
Micron silica 30-40 part,
Bentonite 5-10 part.
The technical scheme further improved as the present invention, high strength cement also includes retarder 5-10 part.
Another object of the present invention is to the preparation method of a kind of anti-fracture lathe ground, use following steps preparation and
Become:
A. by high strength cement, hydroxyl polyurethane, quartz, calcium oxide mixing and stirring, mixture first is obtained；
B. acetic acid-1-naphthalene ester is mixed homogeneously with 1-naphthalene acetic acid and obtain mixture second；
C. the successively place mat of ground, the thickness 5cm of every layer are carried out with mixture second after mixture first being mixed homogeneously；
The most often splashing one layer of water after one layer of ground of paving, the water yield that every layer of ground uses is identical；
E. the ground laid can use after standing 3 days.
Beneficial effect
With high strength cement for foundation strength phase so that ground can bear the impulsive force of higher-strength；Bullet is added in cement
Property phase: hydroxyl polyurethane, 1-naphthalene acetic acid etc., it is therefore an objective under conditions of condensing agent exists, it is possible to part is condensed, introduce firm
Property phenyl ring, also inoganic solids composition entirety bonding can be during condensation so that bear at ground and exceed it simultaneously
During the active force of shear strength, ground can have buffering under the effect of organic flexible chain, will not directly rupture, even if
Foundation Part ruptures, and the slight crack of fracture also will not extend, it is ensured that the stability of ground use and safety.
