Abstract
The utility model discloses a kind of constructing device for clearing up deep water soft clay, it is characterized in that including the air compressor machine set on steel conduit and construction platform, the bottom periphery of the steel conduit is provided with the reamer device being made up of submersible motor and reamer, and the air compressor machine is accessed in steel conduit by air hose.The advantages of the utility model is mainly used in the cleaning of soft clay mud in pile foundation in deep water cushion cap cofferdam, has Device-General, easy to operate and safe, and speed of application is fast, and cost is low.
Description
Technical field
The utility model belongs in water the construction method for clearing up foundation ditch, and in particular to a kind of to clear up applying for deep water soft clay
Frock is put.
Background technology
At present, the deep water soft clay cleared up in cofferdam without more easily method, typically using long-armed digging machine or rig by
Step cleaning.The limitation of existing construction technology：
1st, cleaning depth is inadequate, and existing cleaning plant generally can only achieve within 4m, for the soft clay in cofferdam
Cleaning without preferable method；
2nd, existing cleaning equipment is arranged on the working arm of crawler-mounted excavator, and its work effective radius can not meet will
Ask, construction inconvenience；
3rd, the method that for the mixture formed with sand, cobble, muddy water conduit can be used to blow sand clears up foundation ditch, but the party
Method can not clear up deep water soft clay；
4th, clean-out machine can clear up the foundation ditch of various geological conditions, but incompetent for the angle position in steel pile casting and cofferdam
For power, and with rig cleaning foundation ditch movement is inconvenient, the time is grown, cost is high, uneconomical.
Utility model content
The purpose of this utility model is the deficiency for existing construction equipment technology, there is provided a kind of safer, easy for construction
Fast, the constructing device of cost-effective cleaning deep water soft clay.
Realize that the technical scheme that the utility model purpose uses is as follows：
Clear up the constructing device of deep water soft clay, including the air compressor machine set in steel conduit and construction platform, the steel
The bottom periphery of conduit is provided with the reamer device being made up of submersible motor and reamer, and the air compressor machine is accessed by air hose
In steel conduit.
The beneficial effects of the utility model：
Air compressor machine and steel conduit are the common apparatus of project, easy to assembly, and steel conduit caliber is small, can gamut it is region-wide complete
Into cleaning work, strong adaptability, without being equipped with backing vacuum pump, low investment；Without being equipped with auxiliary stirring or peening device, behaviour
Make easy；Reamer directly contacts riverbed, and by submerged depth controlled concentration, thus concentration control is more freely；From heavy and light, work as needs
Usage quantity can be increased during quickening progress on platform without influence；According to different depth and the sky of clay situation selection corresponding power
Press and submersible motor, can reach ideal effect.
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 be in Fig. 1 A-A to sectional view.
Embodiment
As shown in Figure 1, 2, the constructing device of deep water soft clay is cleared up, including set in steel conduit 3 and construction platform
Air compressor machine 1, the bottom periphery of the steel conduit 3 are provided with the reamer device being made up of submersible motor 4 and reamer 5, the pneumatics
Machine 1 is accessed in steel conduit 3 by air hose 2.
During clear mud construction, constructed using cofferdam method, the bottom of steel conduit 3 is stretched into riverbed with crane, passes through submersible motor 4
Drive reamer 5 to rotate, the soft clay in riverbed is dispersed into the mixing liquid of water and solid particle, start air compressor machine 1, unlatching is sent
Air valve, gases at high pressure enter steel conduit 3 by air hose 2 and produce negative pressure, mud mixture is discharged by steel conduit 3 and reached
To the purpose for gradually reducing riverbed absolute altitude in cofferdam.The cleaning work in all position riverbeds can be completed with crane movement conduit.
In work progress, head must not be less than head outside cofferdam in cofferdam.
