Description
Technical field
The utility model relates to a kind of river immersed tube technical field, specially a kind of hydraulic excavation underwater trench device.
Background technique
Often there is basin and rush lake product silty clay, silt clay in river ground, have high rheological variation and low at ground
The features such as intensity, low-permeability.Along river when interior progress Immersed tunnel, deformation of base compress is big, sedimentation is uneven, if adopting
It is carried out excavating pipe trench operation with conventional excavator excavation, clay meeting quickly stuffing causes pipeline can not normal laying and immersed tube.
Summary of the invention
In order to solve the problems, such as river Immersed tunnel back-silt it is more, pipe trench, this reality can not be excavated using conventional excavator
A kind of hydraulic excavation underwater trench device is proposed with novel.
The hydraulic excavation underwater trench device of the utility model, it is characterised in that the device includes buoyancy tank, bracket, activity
Bar, water-jet pipeline and receiving storehouse, in which:
Buoyancy tank is horizontally placed on top-support two sides, and top-support mid-mounting has bottle gouard moved by hands；Bottle gouard moved by hands two sides are each
It is provided with two motion bars, two motion bars are parallel to each other and hinged with top-support；Motion bar bottom and water-jet pipeline
Transverse pipe it is hinged, be equidistantly positioned several longitudinal pipes in communication below transverse pipe, longitudinal bottom of the tube and inside are provided
The mouth of a river；It is provided between two buoyancy tanks and accommodates storehouse, accommodate storehouse internal high-voltage water pump, accommodate the water inlet for being arranged on storehouse and being connected with high-pressure hydraulic pump
The delivery hose of hose, high-pressure hydraulic pump is connected to water-jet pipeline.
When operation, the device is for cooperating pipeline immersed tube to use, after starting hydraulic excavation underwater trench device, high pressure water warp
By water-jet pipeline directive tube bottom soil layer, tube bottom clay is made to liquefy, lose bearing capacity, pipeline is just embedded to the bottom.To reach
Ideal excavation effect can replace the through-flow aperture of longitudinal pipe water outlet.
In view of the convenience of Immersed tunnel, two buoyancy tank tail portions are fixed by connecting steelframe, connect steelframe and top-support
It is connected, accommodates storehouse and be fixed under connection steelframe against buoyancy tank position.Connection steelframe is set to buoyancy tank tail portion, has reserved Pipe installing
Position makes pipeline remain at top-support vertical lower；Connecting steelframe can ensure that the stability for the device that back-silts simultaneously, simultaneously
It can be used as the operating platform of construction personnel.
Water outlet and longitudinal tube angulation are 105 ° on the inside of the longitudinal pipe of water-jet pipeline, remove back-silt effect most at this time
It is good.
The hydraulic excavation underwater trench device of the utility model, the skill of river ground clay quickly stuffing when solving immersed tube
Art problem, the apparatus structure is simple, using reliable, is worthy to be popularized.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Wherein, buoyancy tank 1, bracket 2, motion bar 3, water-jet pipeline 4 accommodate storehouse 5.
Specific embodiment
Embodiment 1: hydraulic excavation underwater trench device, it is characterised in that the device includes buoyancy tank, bracket, motion bar, water
Power injection pipe and receiving storehouse, buoyancy tank are horizontally placed on top-support two sides, and top-support mid-mounting has bottle gouard moved by hands；Manually
Cucurbit two sides are each provided with two motion bars, and two motion bars are parallel to each other and hinged with top-support；Motion bar bottom and water
The transverse pipe of power injection pipe is hinged, is equidistantly positioned several longitudinal pipes in communication below transverse pipe, longitudinal bottom of the tube and
Water outlet is arranged in inside, and water outlet and longitudinal tube angulation are 105 ° on the inside of the longitudinal pipe of water-jet pipeline；Two buoyancy tank tail portions are logical
It crosses connection steelframe to fix, connection steelframe is connected with top-support, accommodates storehouse and is fixed under connection steelframe against buoyancy tank position, accommodates
Storehouse internal high-voltage water pump accommodates the water supply hose for being arranged on storehouse and being connected with high-pressure hydraulic pump, the delivery hose and waterpower of high-pressure hydraulic pump
Injection pipe connection.
The present embodiment is only some embodiments of the utility model, and the angle of water-jet pipe water outlet should not necessarily be limited by
Range disclosed by the utility model should all fall into the protection of the utility model as long as using the foundation structure of the utility model
Range.
