Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and It is not used in the restriction present invention.
It is described in detail below in conjunction with realization of the specific embodiment to the present invention.
The same or similar label correspond to the same or similar components in the attached drawing of the present embodiment;In description of the invention In, it is to be understood that if having the instructions such as term " on ", " under ", "left", "right" orientation or position relationship for based on attached drawing institute The orientation or position relationship shown, is for only for ease of the description present invention and simplifies description, rather than instruction or the dress for implying meaning Put or element must have specific orientation, with specific azimuth configuration and operation, therefore described in attached drawing position relationship use Language is only for illustration, it is impossible to the limitation to this patent is interpreted as, for the ordinary skill in the art, can be with The concrete meaning of above-mentioned term is understood as the case may be.
It is preferred embodiment provided by the invention with reference to shown in Fig. 1-3.
Big pump amount energy-saving vacuum piling prepressing soft base treatment device provided in this embodiment, for handling the soft Ji Chu of large area The project of reason.
Energy-saving vacuum piling prepressing soft base treatment device provided by the utility model, soft base are added by piling wall and diaphragm seal Solid includes negative-pressure vacuum generator 11, multiple aqueous vapor knockout drums into stabilization zone, energy-saving vacuum piling prepressing soft base treatment device 12 and multiple longitudinal directions be plugged in the drain bar 13 of stabilization zone;Negative-pressure vacuum generator 11 passes through feed pipe 14 and multiple aqueous vapors point Connected from tank 12;Each aqueous vapor knockout drum 12 is connected with multiple hoses 15, and each hose 15 is connected with the supervisor of drain bar 13 17.
In addition, sequentially being connected between multiple drain bars 13 by secondary pipe 16, multiple secondary pipes 16 are connected to supervisor 17, supervisor 17 are connected with hose 15.When the work of 11 devices occurs for negative-pressure vacuum, multiple steam knockout drums 12, each aqueous vapor can be aspirated at the same time Knockout drum 12 can aspirate multiple drain bars 13 at the same time, in this way, the configuration quantity of vacuum pump 21 greatly reduces compared with traditional handicraft, section The expense of equipment purchase has been saved, has greatly reduced power consumption, there is significant economic benefit.The use of energy-saving vacuum pump, makes big The soft base of area is easy to be carried out at the same time processing, and the duration is relatively short, shortens the soft soil consolidation sedimentation time.
When energy-saving vacuum piling prepressing soft base treatment device operates, at the same in soil body diaphragm seal upper strata hydraulic reclamation ox-hide sand and Soil, during vacuum heaping pre-compression, is influenced by vacuum preloading load, and soil mass consolidation produces lateral contraction distortion, and by sand heap The influence that load carries, soil mass consolidation produce lateral extrusion deformation, and above two deformation can cancel out each other, make soft in the construction process Base consolidation settlement speed accelerates unlikely generation failure by shear again, so as to form piling prepressing effect, while can reduce native mesoporous Gap water pressure, increases the effective stress in the soil body.
In the present embodiment, multiple drain bars 13 are arranged in more row patterns, form multiple rows of drain bar group being arranged in juxtaposition, Ge Gepai Water plate group includes multiple drain bars 13 separately arranged, can so cause each drain bar 13 to be evenly distributed, and improves suction The efficiency of water and air in soft base.
In the present embodiment, it is adjacent between two drain bars 13 of drain bar group connected by four-way connection 18, and secondary pipe 16 are connected on four-way connection 18.In implementation process, after adjacent two drain bars 13 are cut flat together with scissors, insertion special four Pass joint 18 is simultaneously fixed up, then usesVacuum time pipe 16 four-way connection is connected and fixed.
In the present embodiment, three-way connection 19 is connected with secondary pipe 16, supervisor 17 is connected on three-way connection 19.For example, willSecondary pipe 16 withSupervisor 17 is connected by 19/ four-way connection 18 of reducing tee connector, forms whole series connection Vacuum body, each vacuum pipe is interpenetrated contact.
Negative-pressure vacuum generator 11 includes vacuum tank 20, vacuum pump 21 and motor 22, vacuum pump 21 and the vacuum Tank 20 connects, and motor 22 drives the vacuum pump 21 to operate, and when motor 22 drives the running of vacuum pump 21, vacuum tank 20 starts Negative pressure is produced, so as to produce suction force to aqueous vapor knockout drum 12 and drain bar 13.
Negative-pressure vacuum generator 11 can set vacuum upper lower limit value, such as upper limit in vacuum tank 20 in supporting control room Value is set as 0.09MPa, and lower limit is set as 0.085MPa, and motor 22 is started to work after equipment startup, gradually extracts vacuum out Air in 20 body of tank, forms negative pressure in tank, vacuum is reached upper limit value 0.09MPa, and motor 22 is automatically stopped operation at this time, Air and pore water in soft base are because pressure difference is extracted, and liquid is discharged after entering aqueous vapor knockout drum 12, and gas is then delivered to In 20 body of vacuum tank, until vacuum is down to lower limit 0.085MPa in tank, a 22 auto-induction opening new round of motor at this time Suction operation, be automatically stopped operation again until vacuum reaches upper limit value 0.09MPa, so circulation repeatedly automatically turn on close Close, vacuum in vacuum tank 20 is remained between upper limit value and lower limit value, the auto-pumping of such negative-pressure vacuum generating means 11 Energy saver, realizes discontinuous operation, reduces invalid suction, reaches the concretion of soft foundation settlement treatment of green high-efficient, makes work efficiency It is more excellent, reduce investment outlay, ecological, environmental protective, easy to managing and quality control.
Aqueous vapor knockout drum 12 is equipped with discharge outlet 23, when water level reach a certain height in tank, can pass through discharge outlet 23 Discharge aqueous vapor knockout drum 12.
The draining pump 24 that water is discharged to discharge outlet 23 is equipped with aqueous vapor knockout drum 12, when water level reaches in gas water separation tank 12 During certain altitude, draining pump 24 is started to work, and the water in gas water separation tank 12 is discharged.
