Abstract
The utility model relates to a kind of trenchless installation structures of cable penetration sea wall.The trenchless installation structure for the cable penetration sea wall that simple, easy for construction, short time limit that the purpose of the utility model is to provide a kind of structures, cost are told somebody what one's real intentions are, neither impacts sea wall main structure, does not also increase difficulty of construction and period.The technical solution of the utility model is: a kind of trenchless installation structure of cable penetration sea wall; pilot hole being formed and through reamer reaming is drilled with by starter it is characterized by: being equipped with below sea wall; the entrance and exit of pilot hole is located at the two sides of sea wall; cable is coated in the pilot hole; protection sleeve pipe is set on the cut cable in pilot hole, between protection sleeve pipe and pilot hole hole wall between gap and protection sleeve pipe and cable gap through grout sealing.The utility model is suitable for cable laying field.
Description
Technical field
The utility model relates to a kind of trenchless installation structures of cable penetration sea wall, belong to cable laying field.
Background technique
The energy is the basis of human social development, and the update of energy technology and the change of variety of energy sources decide human society
The property and mode of development.Since 20th century, being widely used as the chemical fuel of representative using coal and petroleum, but consume chemistry
The carbon dioxide and pernicious gas of fuel draining bring serious environmental problem, the safety of development and the earth to human society
Bring threat.
Wind-power electricity generation has significant society and environmental benefit as clean renewable energy, renewable for pushing
Energy development important in inhibiting, China is completed multiple marine wind electric fields at present.The submarine cable of marine wind electric field is logging in
When inevitably intersect with sea wall, enter inland to enable cable to pass through sea wall, need using certain engineering
Measure.Currently used measure mainly includes crossing over and open cut two major classes.Across being set up using overhead transmission line in sea wall two sides
Steel tower crosses over sea wall.Open cut carries out brokenly dike excavation on sea wall, fills after cable pipe is laid, then to sea
Dike is restored.
It is small on sea wall influence that overhead line crosses dike scheme, but the duration is relatively long, and integrated environment aesthetics is poor, and multiple conversions
Transmission of electricity form causes transmission reliability to reduce, and directly influences this economic benefit of engineering.Dike scheme construction is simple, duration are crossed in open cut
It is shorter, but the dykes and dams for piling up after the completion of pipe laying recovery again are extremely difficult to the unification with original structure integrality, and road surface is through long-term
It is possible to generate differential settlement after rolling, influences the cycle of operation of sea wall.How to realize it is a kind of not only sea wall had been influenced small, but also apply
The convenient method of work is the current field marine wind electric field cable Chuan Di problem to be solved.
Summary of the invention
Technical problem to be solved by the utility model is: for above-mentioned there are problem, provide that a kind of structure is simple, construction party
Just, the trenchless installation structure for the cable penetration sea wall that short time limit, cost are told somebody what one's real intentions are, neither impacts sea wall main structure,
Also do not increase difficulty of construction and period.
The technical scheme adopted by the utility model is a kind of trenchless installation structure of cable penetration sea wall, feature
Be: being equipped with below sea wall and pilot hole being formed and through reamer reaming is drilled with by starter, the entrance of pilot hole and
Outlet is located at the two sides of sea wall, is coated with cable in the pilot hole, guarantor is set on the cut cable in pilot hole
Protecting pipe, between protection sleeve pipe and pilot hole hole wall between gap and protection sleeve pipe and cable gap through grout sealing.
The pilot hole inlet is provided with drilling machine and auxiliary device, and pilot hole exit is equipped with for by the institute on drilling machine
State the workbench that starter is changed to the reamer.
The starter is provided with the transmitting set that can be sent out the status information of starter.
Mud off is used when the starter drills.
The beneficial effects of the utility model are: the construction period of the utility model is shorter, it is not subject to seasonal restrictions；Pass through sea wall
Path on the way can be controlled by mechanically actuated with angle, i.e., in drilling process, drilling machine and attached corollary equipment can be shown at any time
Depth, horizontal position and the inclination angle of starter, from the damage to original place based structures, the influence to sea wall main structure is very
It is micro-.
Detailed description of the invention
Fig. 1 is the arrangement schematic diagram of embodiment.
Specific embodiment
As shown in Figure 1, a kind of trenchless installation structure of cable penetration sea wall, is equipped with pilot hole 9 below sea wall 3, it should
The entrance and exit of pilot hole 9 is located at the two sides of sea wall 3, and cable 7 is coated in pilot hole 9, the electricity in pilot hole 9
Protection sleeve pipe 8 is set in cable section.To prevent inwelling, gap and protective case between 9 hole wall of protection sleeve pipe 8 and pilot hole
Gap is handled through grout sealing between pipe 8 and cable 7.
Pilot hole 9 is drilled with by starter 2 in the present embodiment formed after, then formed through 6 reaming of reamer.In pilot hole 9
Inlet is provided with drilling machine and auxiliary device 1, and 9 exit of pilot hole is equipped with for the starter 2 on drilling machine to be changed to expansion
The workbench 4 of hole device 6.
It is provided with transmitting set in starter 2 in this example, it can be by starter by transmitting set
Depth, horizontal position and obliquity information are sent to drilling machine and auxiliary device 1, in drilling process, drilling machine and attached corollary equipment 1
Depth, horizontal position and the inclination angle of starter 2 can be shown at any time.
The concrete construction method of the present embodiment is as follows:
Construction personnel a little bores one and expected rail to unearthed point under the guidance of drilling machine and attached corollary equipment 1, from burying
The identical pilot hole 9 of mark, when drilling, use 5 retaining wall of mud.
Then starter 2 is guided into workbench 4, removes starter 2, then loaded onto reamer 6 and start reversely to expand
Hole.Above-mentioned steps are repeated according to soil property situation, increase bore diameter, classification reverse drawing rotates hole-enlarging hole-forming.
After completing reaming, obstacle clean, not impassable in hole is confirmed, progress cable 7, which returns, immediately drags.Cable 7 is adopted
Dragging drawing is carried out with the elevator machine equipment in construction site on the inside of land-based area, cable 7 and protection sleeve pipe 8 are worn along reaming rear path
The guide hole site being more arranged on the inside of sea wall bottom to sea wall, completes cable penetration sea wall.
After the completion of cable wears dike, carried out between 9 hole wall of protection sleeve pipe 8 and pilot hole and between cable 7 and protection sleeve pipe 8
Closure processing, prevents inwelling.
Certainly, above description is not limitation of the utility model, and the utility model is also not limited to the example above, this skill
The those of ordinary skill in art field, in the scope of the utility model, variation, addition or the replacement made all should belong to this reality
With novel protection scope.
