Specific embodiment one
Certain city city drinking water water intake engineering Reconstruction Project crosses 360 meters of length of pipe network of river section, using Immersed tunnel technique.
This section about 6 meters of the river ordinary water level depth of water, 5 meters of channel excavation mean depth, riverbed geology from top to bottom be respectively Muddy Bottoms clay,
Fine sand, slightly close cobble, intense weathering munstone, middle weathered mudstone, riverbed geologic change is big, and wherein the K0+640-K0+750 sections of cubic meters of stone are opened
It digs and is constructed using underwater demolition, constructed using the embodiment of the utility model.
The design of hull 1, according to the required spatial position size for reaching each functions of the equipments of simple underwater drilling and blasting ship and using, with
And it is manually designed in upper operated a security situation.
Existing 100 specification of assembling-type cabinet ship be 14 meters × 3.5 meters × 1.5 meters, by each equipment arrange calculating,
Most narrow needs to reach 8 meters using width, and single cabinet ship 100 is unable to satisfy, and 3 cabinet ships 100 is needed to be arranged side by side, and is formed
14 meters × 10.5 meters × 1.5 meters of operation plane.
Specifically, the side of assembling-type cabinet ship 100 is equipped with multiple protrusions 1001 for splicing, shape between protrusion 1001
At the groove for setting protrusion 1001 for card, protrusion 1001 is equipped with multiple for wearing the perforation 1002 of bolt 101.Pass through bolt
101 are quickly and easily assemblied into assembling-type cabinet ship 100 hull 1 of needs.
Assembled hull geometric dimension is 14 meters × 10.5 meters × 1.5 meters, hull mass 45T, hull theory buoyancy: 14 ×
10.5×1.5=220.5T；Hull enter the draft after water according to hull 14 ÷ 10.5 of displacement Simple Calculation=45 ÷=
0.3m。
The weight of each equipment is respectively as follows: hidden hole drilling 2,0.5T, air compressor machine 3,3T on ship, and positioning hoist engine 4 has 4,2T/
A, total 8T, tube drawing hoist engine 62 have 1,5T, and lifting-positioning device has 2,7T/, total 14T, and pipe drawing device 6(removes tube drawing
Hoist engine 62) there is 3T, it carries and presses 15 people about with total 1.5T, operating personnels such as the intracorporal diesel engine of ship, hydraulic oil container, oil pumps
1T, load amounts to 36T on ship.
1 draft of hull=14 10.5=0.55m of ÷ of (45+36) ÷ after fully loaded.
Hull 1 exposes the surface height for 1.5-0.55=0.95 meter > 0.5 meter (considering the high minimum full construction height of wave), completely
Sufficient construction safety demand.
When operation, hull 1 is opened to construction waters, using small boat cargo ship anchor 41 to position of casting anchor, by ship anchor 41
Positioning of casting anchor is carried out after the traction rope of connection positioning hoist engine 4.Hoist engine 4 is positioned using self weight 2T, pulling force is the model of 5T.
It is operated by hydraulic motor 56, rotates, engaged by the cylinder 54 with lifting groove 53, realized under guide pile 52
Drop.Specific guide pile 52 is designed as 10 meters, meets the construction positioning requirements in current waters.Preferably, the hydraulic motor
56 Power Components can use the walking hydraulic package of 350 excavators.In lifting process, limit plate 51 and limit pin shaft 59
The lifting of guide pile 52 is effectively limited to vertical lifting, it is ensured that the vertical degree of positioning.Using hydraulic-driven, decline stability
It is good, and can have enough power drive guide piles 52 to be inserted into riverbed.Preferably, 52 bottom of guide pile is wedge-shaped part 58, just
It is inserted into riverbed certain depth in guide pile 52, improves the stability of positioning.The positioning of this programme, effectively by flexible fixed system and
Half jacking hydraulic lifting system combines, and makes hull is stable to bubble through the water column, ejects the water surface without by hull, can satisfy construction
In the case where required precision, the demand to hydraulic device is greatly reduced, reduces a large amount of equipment cost, reduces live ship
The production assembly difficulty of body.
It after the completion of positioning, can be drilled, insert steel sleeve (hole is avoided to be blocked by river sand), increase set pvc pipe (for replacing
Steel sleeve reduces guard aperture cost), the subsequent blast working process such as pull out steel sleeve.During tube drawing, tube drawing hoist engine is utilized
62, it is 8T that pulling force, which specifically can be used, is self-possessed and is acted on to be pulled out for the hoist engine of 5T by pulling rope 63 and fixed pulley 61
Steel sleeve is, it can be achieved that tube drawing.
The checking computations of steel sleeve pulling capacity: regarding steel sleeve as stake, and tube drawing needs to overcome the vicinity soil body that (this place will be all
The soil body is enclosed to consider according to sand) to the force of negative friction and casing dead weight of casing generation.Using casing as research object, carry out by
Power is analyzed as follows:
Pulling force T > frictional force fn+ self weight G,
Every meter of steel sleeve weight G1ρ/1000=(D-t) * t* π *,
Total weight G=l*G of 4.5m casing1,
The force of negative friction f that casing is subject to is estimated according to the model of selectionn:
fn=2N+30, N are the blow counts of close sand in standard penetration test (SPT), and 15 N≤30 <, this place takes N=16；
Data are brought into obtain:
G=388kg；fn=62KN obtains 6.588 tons of T >；
Therefore the hoist engine that lifting weight should be selected to be greater than 6.588 tons, construction needs, the drawing that this programme uses can be met
Power/lifting weight is the hoist engine of 8T, fully meets construction demand.
The utility model particularly suitable for not having the inland river of navigation condition, plateau lake etc., riverbed depth in 12 meters,
Environment under 3 meter per second of flow rate of water flow, and need the cubic meter of stone of explosion fragmentary, small situation is measured, hull dismounting transhipment is convenient,
Single accessory size is less than standardised transportation specification.Have at low cost, easy for construction, the features such as good positioning effect, suitable popularization is answered
With.
