Description
The application is application No. is 2016101552179, and the applying date is on 03 18th, 2016, and invention and created name is
A kind of divisional application of the patent of " lathe ground for being established on the ground in weak soil ".
Technical field
The invention belongs to soft soil foundation field, specially a kind of lathe grounds for being established on the ground in weak soil.
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 domestic heavy machine tool presently, there are one of main problem 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 to make
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 include using weak soil compacting equipment, the weak soil compacting equipment：Nip drum
Machine and two sets of rail pressure devices；The reinforcement means includes the following steps：A drafts of soft soil foundation is determined first；Setting
Four fixed foundation points；By nip drum machine setting in 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, to be compacted to the soft soil foundation,
Until practical drafts meets the requirement of overall reduction.For another example Chinese patent CN1957143A " reinforcement means of soft soil foundation ",
In the inside of the ground of consolidated subsoil peripheral portion, vertical drainage part is set, forms vertical row supply passageway, is supplied in the vertical row
The inside of access pours into the water with sealing part, and by above-mentioned vertical supply passageway, the water with sealing part is supplied to reinforcing
The inside of the ground of ground peripheral portion, the sealing part being circulated into above-mentioned vertical supply passageway are spread in vertical confession with flow
To the periphery of access, sealing region is formed, effect is：Consolidated subsoil peripheral portion is hindered by the sealing region that sealing part is formed
Ground inside underground water movement, can inhibit the consolidated subsoil periphery of the forced drainage of the underground water with consolidated subsoil
The decline of the underground water of the inside of the ground in portion can effectively inhibit the consolidated subsoil peripheral portion of the reinforcing with soft soil foundation
The sedimentation of ground.
The above method is to carry out compacting or the firm ground of drain reinforcing method foundation to soft soil foundation, great in constructing amount,
Program is complex, and labour cost is higher, and the ground established is unable to antidetonation resistance to compression, and service life is short.
Invention content
In order to solve the above technical problem, the present invention provides a kind of lathe grounds for being established on the ground in weak soil, can
The foundation that weak soil carries out lathe ground on the ground is directly acted on, construction volume and human cost are reduced.
To realize the above-mentioned technical purpose, the specific technical solution that the present invention takes be using foam cement construction and
At the foam cement includes the substance of following parts by weight：
20-30 parts of modified acroleic acid epoxy resin,
- 3 parts of phosphatase 11,
3-10 parts of zinc powder,
3-8 parts of water,
10-13 parts of glycerine,
8-10 parts of polyvinyl alcohol,
30-60 parts of Iron-ore Slag,
15-30 parts of ceramic microsphere, wherein modified acroleic acid epoxy resin be 1,4,5,8- naphthalenetetracarbacidic acidics and acrylic acid epoxy
Resin in molar ratio 1：1 is obtained by the reaction.
Technical solution as an improvement of the present invention further includes 1-3 parts of catalyst, and the catalyst is heteropoly acid, miscellaneous more
The sodium salt or aluminium phosphate molecular sieve of acid.
The mass concentration of technical solution as an improvement of the present invention, phosphoric acid is 60%-85%.
Technical solution as an improvement of the present invention further includes 3-8 parts of coupling agent.
Technical solution as an improvement of the present invention, the coupling agent are preferably silane coupling agent.
Technical solution as an improvement of the present invention, it is to use to establish lathe ground on the ground in weak soil：By modified acroleic acid
Epoxy resin, polyvinyl alcohol, glycerine, ceramic microsphere, Iron-ore Slag, zinc powder, water, phosphoric acid are uniformly mixed construction in order.
Advantageous effect
A kind of lathe ground honeycombed cement provided by the invention, in ingredient comprising resin of the benzene ring structure with carboxyl with
Polyalcohol, the big calorimetric discharged during zinc powder, Iron-ore Slag and phosphatase reaction generate the passivating film with anticorrosion structure
Under the action of can generate the organic substance with rigid structure and flexible structure, and the organic substance generated is that polarity is organic
Object, can adsorb hydrone in weak soil to cement it is porous in, and then improve the intensity of cement.Simultaneously as first by metallics
It is uniformly mixed with resin so that during phosphoric acid is subsequently added, metal generates the hydrogen discharged during passivating film with phosphoric acid
Gas can be uniformly distributed in entire cement ground so that cement ground has even porous structure.And porous structure has centainly
Water imbibition therefore can make full use of weak soil groundwater resources, realize the consolidation of ground, and prolongedly with the time
Base only can be consolidated increasingly；And simultaneously, after construction building, ground be honeycombed cement ground, can have it is shockproof, insulate against sound and
The propagation of Isolation stress.
