Description
Technical field
The mixed gravel construction technology of ship excavation clay is inhaled the invention belongs to ship dredging construction technical field, more particularly to a kind of twist.
Background technology
As a kind of special desilting material, clay, gravel composite soil are relatively common in dredging work, particularly Dalian
Port near zone.Because more harbour is proposed in the mixed soil property littoral zone of clay gravel, therefore research clay gravel mixes soil property construction technology
There is very important realistic meaning with method.
Existing ship dredging construction technique does not consider that clay mixes the particular/special requirement that gravel soil property is brought, using traditional construction
When technique is excavated, easily produce the stifled reamer of paste, suppress the problems such as quick-fried fluid pressure line.Therefore develop a kind of suitable for clay
The construction technology of mixed gravel soil property is the active demand of current this area, it may have broader market prospects.
The content of the invention

Embodiment
In order to further understand the content, features and effects of the present invention, it is as follows hereby to lift following examples detailed description：
The strand of the present invention, which inhales ship and excavates clay and mix gravel construction technology, to be comprised the following steps, and (1), which will be twisted, inhales ship and sail to opening
Dig original position and cast anchor the step of in position；(2) pair twist inhales the step of vessel position is adjusted；(3) decentralization reamer is to top
Mud layer carries out the step of constructing of dredging；Reamer is transferred to 2a/3 distance by original mud face, wherein a puts down for the mud layer that measurement is obtained
Equal thickness, this layer is carried out by forward pitch of b and is dredged construction；(4) fall from power car the step of, chassis refunds positional distance origin position and is
1.0m；(5) decentralization reamer carries out the step of constructing of dredging to lower section mud layer；Under depth continues where when reamer is excavated by upper strata
Put a/3 distance, the mud layer average thickness that wherein a obtains for measurement carries out this layer by forward pitch of c and dredged construction；Lower floor applies
The 1.0m regions left when man-hour constructs upper strata connect a batch excavation construction again；(6) fall from power car the step of, chassis is refunded to origin
Position；(7) the step of moving traversing anchor；(8) the step of moving ship.
In the present embodiment, b is 1.0~1.2m, and c is 0.5~0.6m.
In the present embodiment, upper strata single digging distance is 5.0m, and lower floor's single digging distance is 6.0m.
In the present embodiment, twist and inhale ship using pointed tooth type reamer tooth, anti-stone ring is installed on reamer.
Technological principle is as follows：
The rotation that cutter suction dredger is constructed mainly by reamer excavate and dredge pump suction it is defeated complete, twist and inhale ship and excavate production
Rate it is main with forward pitch, to cut the factors such as mud thickness, transverse moving speed relevant.In excavation mud face during relatively thin soil layer, using " small progress
The construction technology of fast swing ", i.e., by controlling forward pitch, cutting mud thickness and transverse moving speed, make reamer load relatively steady, obtains
Stable construction concentration, can obtain ideal effect.In excavation mud face during thicker soil layer, using " separate unit in-car is drawn
The construction technology of drawer ", i.e. upper strata are entered after 5.0m, receive chassis construction lower floor and enter 6.0m, while the 1m that upper strata is left connects again
Stubble is excavated, it is to avoid is caused the wide phenomenon being gradually reduced of pendulum because the viscous hard, residual layer of soil property is thicker, is improved the excavation productivity ratio of ship.
Concrete application example is as follows：
Measurement obtains dredging thickness degree for 5.5m, for save the layering shifting ships caused more, move anchor, the productivity such as car of falling from power is stopped
Have a rest the time, take the grooving technology construction of drawing drawer one time of two layers of separate unit in-car point.
1) the first separate unit car is layered：Reamer is once transferred to -6.8m (to prevent from back-silting, when upper strata is constructed from original mud face
The many lower 0.3m of reamer decentralization depth) forward pitch is 1.2m.Reamer electric current and suction vacuum and concentration are controlled according to transverse moving speed,
First step forward pitch than moving forward apart from big 0.3m or so below after zapping car, and other reaches are apart from of substantially equal.
2) the second separate unit car is layered：Reamer once transfers to -8.7m that (the timely depth measurement of measured ship, is being opened from -6.8m
When reamer decentralization depth is -8.6m when digging down layer, sound the depth of the water as 8.0~8.1m.Consider the phenomenon of back-silting before the acceptance of work,
Reamer transfers to -8.7m to ensure construction quality when excavating lower floor), forward pitch is 0.6m (because lower floor's shale is silty clay
Mixed circle gravel, reamer head easily pastes dead and to reamer centrum and weares and teares very big, so when excavating lower floor, forward pitch is than upper strata excavation
Suitably reduced during construction).
After the analysis sounding chart depth of water in time and by multiple practice test, " the new construction work of upper 5 times 6 " is taken now
Chassis, i.e., received 1.0m, upper strata enters 5.0m, lower floor and enters 6.0m when so doing upper strata by method when lower floor falls from power car.Excavate
The 1.0m left when upper chassis being excavated 5.0m again during lower floor connects stubble and excavated again, and prevention is led because soil property is viscous firmly, residual layer is thicker
Causing pendulum width to be gradually reduced causes ship to shoulder neck phenomenon, and construction quality is effectively ensured.
When strand suction ship excavation clay gravel mixes soil property, larger to reamer, reamer tooth, toothholder, the abrasion of reamer cone, part is easily collapsed
Collapse and cause suction vacuum moment rapidly to increase to form shake car phenomenon, it is to excavate clay gravel to mix to solve landslide, shoulder neck, wear problem
The key of soil property, construction ship uses pointed tooth type reamer tooth, and installs on reamer anti-stone net.
Contain a large amount of quartzy dusts, circle gravel to the reamer tooth of ship, reamer toothholder, reamer body, hull suction in construction area
Mud pipeline, rubber pipe nipple, it is waterborne under water and land mud delivery pipeline abrasion than more serious.For ensure ship improve when interest rate have with
What time it is worth noting down：
1) reamer tooth and toothholder should use wear resistant products, extend monodentate service life, and tooth number of times and time are changed in reduction；
2) workshop repairing is entered in the abrasion reamer requirement under changeing.It is existing because reparation of freezing has temperature requirement when weather is cooler
Easy fracture during the toothholder work repaired under the open-air condition of field；
3) increase the spares provisioning of corresponding ship rubber hose, improve spare part quality, it is to avoid ship is caused by waiting spare part
Shut-down phenomenon occur；
4) due to it is waterborne, under water, terrestrial pipeline abrasion it is more serious, live project management department to respective lines increase spot thickness measurement
Check, the service life to pipeline position easy to wear carries out shifting to an earlier date anticipation, and welding liner plate thickeies pipeline position easy to wear in advance,
The improvement face of doing work, face is turned to respective lines using ship downtime and used, reduce due to issue pipeline cause when resting
Between.
