Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings, to enable those skilled in the art referring to specification text
Word can be implemented accordingly.
It should be appreciated that such as " having ", "comprising" and " comprising " term used herein do not allot one or more
The presence or addition of a other elements or combinations thereof.
In a kind of technical solution, as shown in Figure 1, 2, 3, harbour large area super soft ground processing method, comprising:
Step 1: being laid with sand bedding course 1 above super soft ground；
Step 2: setting multiple groups drainpipe 4 vertically in super soft ground, every group of drainpipe 4 includes the more of annular spread
A drainpipe 4, the drainpipe 4 include supervisor and multiple wing plates 401, are formed with multiple first on the side wall of the supervisor and open
Mouthful, first opening is in bar shaped, and along the axially extending of the supervisor, is formed with hollow chamber inside the wing plate 401,
401 side of wing plate is formed with the second opening being connected to the hollow chamber, and the wing plate 401 is fixed on described first and opens
At mouthful, and make first opening and second open communication, 401 surface of wing plate is distributed with and the hollow chamber
The fish scale hole 402 of connection, the opening of the fish scale hole 402 is towards the supervisor upper end；
Step 3: the center vertical in every group of drainpipe 4 sets central tube 5,5 lower end closed of central tube, it is described in
5 inside of heart cylinder is arranged at intervals with two bearing blocks 502 up and down, and a shaft 501 is coaxially arranged with inside the central tube 5, described
Shaft 501 is supported by two bearing blocks 502, is further fixed on eccentric wheel 503 in the shaft 501；
Step 4: ring packing ditch 2 is dug every group of 4 periphery of drainpipe, then above sand bedding course 1 and in sealing ditch 2
It is laid with sealing film 3；
Step 5: the supervisor upper end, which is passed through connecting tube, is connected to vacuum pump 6, vacuumize process process is carried out, and
The shaft 501 is connect with a motor 504, so that shaft 501 and eccentric wheel 503 rotate；
Step 6: sealing film 3, connecting tube and motor 504 are removed, to 4 He of drainpipe after vacuumize process process
Grouting in central tube 5.
In the above-mentioned technical solutions, it is lacked for the drain bar of existing vacuum method insertion super soft ground is susceptible to plugging
It falls into, drainpipe 4 is circular layout, the central tube 5 that then setting can produce vibration at center utilizes in carrying out aspiration procedure
The vibration of central tube 5 provides drainage speed, reduces a possibility that drainpipe 4 blocks.Sand is laid with above super soft ground first
Then bed course 1 sets drainpipe 4 and central tube 5, drainpipe 4 is arranged around central tube 5, i.e., by entire harbour large area ultra-soft
Soil base multiple groups drainpipe 4 is divided into junior unit；Then sealing ditch 2 is dug in every group of outer collarette of drainpipe 4, and with sealing film 3
Cover sand bedding course 1 and sealing ditch 2；Then setting vacuum pump 6, connecting tube and motor 504, are aspirated and are vibrated, and draining is completed
Process；Finally remove connecting tube and motor 504, the slip casting into drainpipe 4 and central tube 5, for adding for subsequent super soft ground
Gu.Drainpipe 4 includes supervisor and wing plate 401, and wing plate 401 is located at around supervisor in expansion shape, and 401 area of wing plate is big, and surface
Fish scale hole 402 is distributed with, water is facilitated to enter, 402 opening upwards of fish scale hole are avoided when setting drainpipe 4, and mud blocks fish scale
Hole 402.Rotatable shaft 501 is set inside central tube 5, and shaft 501 is driven by motor 504, also sets up bias in shaft 501
Wheel 503, when shaft 501 is driven by motor 504, eccentric wheel 503 also rotates, so that central tube 5 is whole to generate vibration.Central tube 5
Diameter, central tube 5 be rationally arranged at a distance from drainpipe 4, the vibration of central tube 5 is transferred at drainpipe 4, it is right
Water pressure in super soft ground, promotes water to enter drainpipe 4, and the soil body near drainpipe 4 is vibrated, subtracts to a certain degree
The blocking of few fish scale hole 402.As can be seen that the technical program can be improved and keep the drainability of vacuum method.
In another technical solution, the harbour large area super soft ground processing method, the multiple first is opened
Mouth is symmetrically distributed in supervisor's side wall, and the wing plate 401 is by close to supervisor, to far from supervisor, thickness is sequentially reduced, the wing
Plate 401 is by close to supervisor, to far from supervisor, width is sequentially reduced.Here, so that wing plate 401 is in spininess, aspect wing plate 401 is inserted
Enter ground, symmetrically expansion is distributed in supervisor two sides to wing plate 401, and receiving is facilitated to vibrate bring water by central tube 5.
In another technical solution, the harbour large area super soft ground processing method, in the hollow chamber
Filled with geofabrics.Here, geofabrics have water penetration, reduce mud and enter supervisor.
In another technical solution, the harbour large area super soft ground processing method, it is described supervisor and it is described
Central tube 5 stretches out the sand bedding course 1, annular groove 101 is dug around the central tube 5, and be laid in annular groove 101
Seal film 3.Here, wing plate 401 is located in super soft ground, and it is recessed to dig annular in the portion that central tube 5 stretches out sand bedding course 1
Slot 101 is laid with sealing film 3 in annular groove 101, improves overall tightness.
In another technical solution, the harbour large area super soft ground processing method, further includes:
Connecting rod is set, and connecting rod one end and central tube 5 is fixed, and the other end and supervisor fix.Here, connecting rod can be with
Between the centrally disposed cylinder 5 of mode that overlapped and supervisor, for the vibration of central tube 5 to be transferred to supervisor, promote wing plate 401 weeks
The soil body vibration enclosed, reduces a possibility that fish scale hole 402 blocks.
In another technical solution, the harbour large area super soft ground processing method, the central tube 5 and institute
The spacing for stating supervisor is 10~15 times of 5 diameter of central tube, and the spacing of adjacent two supervisors is no more than 401 length of wing plate
4~5 times.Here there is provided a kind of set-up modes of central tube 5 and supervisor, and central tube 5 is preferably transmitted vibration
To supervisor.
Number of devices and treatment scale described herein are for simplifying explanation of the invention.To the big face in harbour of the present invention
The application of product super soft ground processing method, modifications and variations will be readily apparent to persons skilled in the art.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
