Abstract
The invention discloses a pipe and plate connection piece. The pipe and plate connection piece comprises a circular connector at the upper part, a cavity in the middle part and a slot located at the lower part of the cavity, wherein the slot is internally and convexly provided with a row of square opening pipes; and the pipe and plate connection piece is mainly used for coupling air conduction channels in a core plate of a water discharging plate with a branch pipe of a vacuum pipeline when the plastic water discharging plate with double water discharging channels is used in a vacuum pre-pressing fastening soft base method. The circular connector is connected with the branch pipe of the vacuum pipeline; the square opening pipes are connected with inner holes of the pumping and discharging plastic water discharging plate with the double water discharging channels; the circular connector is further provided with a check valve. According to the pipe and plate connection piece disclosed by the invention, the loss of a vacuum degree in a process of transmitting the vacuum degree from a vacuum pipeline system to the water discharging pipe is reduced, and the transmission efficiency is improved; the loss of vacuum pressure in a sand cushion layer is reduced, and the requirements of sealing are reduced; topsoil and soil below a surface layer can be directly used as a covering and sealing layer; and the pipe and plate connection piece disclosed by the invention is simple to manufacture and can be produced in a factory in a large batch.
Description
Technical field
The present invention relates to a kind of novel tube sheet connector, the member that belongs to construction engineering technical field, specifically use in the method for vacuum prepressing reinforcement soft base while having the pump-drainage type plastic draining board of dual-drainage passage, connect band drain and vacuum pipe device arm tube sheet connector used.
Background technology
The vacuum preloading processing method that at present processing of soft foundation is adopted, it is the horizontal sand cushion of laying on soft foundation, squeeze into band drain in ground, band drain is interconnected and is embedded in formation horizontal drainage passage in sand cushion by the supervisor on vacuum plant and chimney filter, then cover air-locked diaphragm seal thereon.Adopt vacuum plant to bleed and say that in film, the ground Air is extracted out, make draught head of the inside and outside generation of film, this draught head acts on ground, is equivalent to have increased a load to ground and carries.Along with the empty G﹠W in film constantly is discharged from, this draught head constantly increases, and the moisture in ground passes through band drain, sand cushion, chimney filter under the effect of negative pressure of vacuum simultaneously, supervisor discharges but the ground generation is fixed, makes the strength increase of ground.
Yet traditional preloading but so have some problems, be mainly manifested in: (1) is if top layer has gas permeability, the good ground of water permeability, in order to prevent gas leakage, diaphragm seal must be imbedded the ground of hypotonicity darker under it, or partition mud wall to lower floor is set in this layer soil, this job practices is very uneconomical, and sometimes can also guarantee sealing; (2) vacuum pressure is subject to the damping action of sand cushion and chimney filter, filter membrane in transmittance process, power loss is very large, field data shows, the vacuum pressure outlet pressure is 96kPa, through supervisor, when chimney filter arrives sand cushion, vacuum pressure is reduced to 80 ~ 90kPa, while through sand cushion, arriving band drain 3m place, only have 50 ~ 60kPa, loss late reaches more than 30%.
Summary of the invention
Purpose of the present invention is to overcome above-mentioned defect exactly, a kind of easy construction, simple to operate is provided, reduce vacuum by vacuum pipe system to the loss in the band drain transmittance process, improve vacuum and transmit the tube sheet connector of usefulness and consolidation effect, it is mainly to design for the plastic draining board with dual channel, and its purpose connects air guide channel and the vacuum pipe arm on its central layer while using this to have the novel plastic band drain in the vacuum prepressing reinforcement soft base method.
The present invention is achieved through the following technical solutions:
A kind of tube sheet connector, comprise the circular interface on top, the cavity at middle part and the slot of cavity bottom, the projecting inward row's square opening pipe that arranges of slot, described circular interface is connected setting with the vacuum pipe arm, and the square opening pipe is connected setting with the central layer endoporus of the pump-drainage type plastic draining board with dual-drainage passage; Described circular interface also is provided with one way valve.
Described square opening pipe is taper, and the outside bore of square opening pipe is slightly less than band drain endoporus bore, and square opening pipe base portion is slightly larger than band drain endoporus bore.
Described tube sheet connector is that plastics or metal material are made.
Beneficial effect of the present invention is:
(1) reduce the vacuum transmission loss, improve and transmit usefulness;
(2) reduced the requirement of sealing, but can be directly native as upper covering sealant once with the topsoil top layer;
(3) after termination of pumping, one way valve is closed automatically, can keep the negative pressure of vacuum in plastic draining board, does not affect the reinforcing progress, reduces the operating expenses cost;
(4) make simply, can produce in batches in factory.
Description of drawings
Fig. 1 is tube sheet connector connection diagram of the present invention;
Fig. 2 is tube sheet connecting-piece structure schematic diagram of the present invention.
Wherein: 1, the vacuum pipe arm; 2, the tube sheet connector main body; 3, have the pump-drainage type plastic draining board of dual-drainage passage; 4, air guide channel; 5, spaced trenches; 6, the square opening pipe; 7, slot; 8, cavity; 9, one way valve; 10, cross section.
The specific embodiment
Now by reference to the accompanying drawings, technical scheme of the present invention is further explained.
the main purpose of tube sheet connector is the air guide channel 4 that connects vacuum pipe arm 1 and have the pump-drainage type plastic draining board central layer of dual-drainage passage as shown in the figure, the circular interface that is connected with the vacuum pipe arm is arranged at this tube sheet connector top, interface is provided with one way valve 9, middle part is cuboid cavity 8, the cavity bottom is slot 7, the projecting inward row's taper square opening pipe 6 of slot, the number of the taper square opening pipe of projection is consistent with the number of gas port in this novel plastic band drain central layer, when the tube sheet connector is connected with band drain 3, the air guide channel 4 of band drain is over against the square opening pipe 6 of tube sheet connector, then tightly be enclosed within on this square opening pipe 6, prevent joint gas leakage.Band drain, connector, arm, supervisor and vacuum pump interconnect and form vacuum pressure transmission system and drainage system, vacuum pump directly is delivered to negative pressure of vacuum air guide channel in the middle of band drain in the soil layer of different depth by supervisor, arm, connector, reduces vacuum by the loss of horizontal pipe system to the band drain transmittance process.Use simultaneously this connector can avoid arranging diaphragm seal, also reduced the loss of vacuum pressure in sand cushion.
Further, described square opening pipe is taper square opening pipe, and number is consistent with the number of air guide channel 4 in the band drain central layer, the outside bore of square opening pipe is slightly less than the bore open of the air guide channel in the band drain central layer, square opening pipe base portion is slightly larger than the bore open of air guide channel, and its main purpose is fully to connect band drain and vacuum pipe arm, prevents gas leakage, reduce the loss of vacuum, improve the transmission efficiency of negative pressure of vacuum.
Further, described tube sheet connector can be plastics or metal material is made.
