Detailed description of the invention
Consult Fig. 2 and Fig. 3, the preferred embodiment of seepage tunnel of the present invention construction method comprises following steps:
Step claims S1-Drilling tunnel 20, and this tunnel 20 has the first end 27 being communicated to face, land 7, and close to but be not communicated with second end 28 in high pressure waters 8.This high pressure waters 8 is the deep ocean water water source of marine dark about 300 meters in the present embodiment, but looks demand also adjustable depth drilled.This tunnel 20 locates toward downward-extension 3000 meters to vertical depth 300 meters with the proportional tilt of length and depth ratio 10:1, again toward direction, high pressure waters 8 horizontal-extending, end forms this second end 28, the distance about 5 to 8 meters in this second end 28 and this high pressure waters 8.Based on the consideration safeguarded with ventilate, also to extend and in order to the liaison tunnel 5 safeguarded and ventilate Drilling this seepage tunnel 20 parallel again, and connect the access road 6 of this seepage tunnel 20 and this liaison tunnel 5.But liaison tunnel 5 is nonessential, its difference holds rear explanation.
Step S2-in this tunnel 20, the horizontal-extending place of this second end 28 contiguous arranges gate 3, this tunnel 20 is divided into the first paragraph 21 near face, land 7 and the second segment 22 of position in the contrary side at first paragraph 21 of this gate 3.The length of first paragraph 21 as aforementioned about 3000 meters, the long-range second segment 22 at about 30 meters.Access road is located at this gate 3 place, maintains easily.
Step S3-at least this first paragraph 21 water filling.It should be noted that except the mode directly entering step S4 after this first paragraph 21 water filling, to also have two kinds also in the enforcement aspect of second segment 22 water filling except closed shutter 3.
One is as shown in Figure 4, first one or more non-through aperture 221 is arranged in advance with the drilling technique of advanced person at the second end 28, and to arrange explosive 222 from the second end 28 toward direction, high pressure waters 8 mode radially, explosive 222 closest to high pressure waters 8 part, with high pressure waters 8 at a distance of about 0.6 to 1 meter.Ignite in advance at the explosive 222 near external high pressure waters 8 during explosion, blow crag non-through between aperture 221 and high pressure waters 8, this second segment 22 is communicated with high pressure waters 8 part with aperture 221, second segment 22 is injected in advance with a small amount of seawater in high pressure waters 8, then enters step S4 and be communicated with second segment 22 and high pressure waters 8 comprehensively.
Another kind is as shown in Figure 5, the second end 28 first in this tunnel 20 is with after being carried out explosive and arranging from the second end 28 toward direction, high pressure waters 8 mode radially, keep gate 3 in opening, directly in this first paragraph 21 and the water filling simultaneously of this second segment 22, then enter step S4.
Step S4-be comprehensively communicated with second segment 22 and high pressure waters 8.The state that this gate 3 is being opened, the diversion in this face, land 7 of formation connection as schematically shown in Figure 6 and this high pressure waters 8 is with road 2.This step adopts comprehensive explosion, this high pressure waters 8 of comprehensive connection, when high pressure sea water enters seepage tunnel 2, due at least this first paragraph 21 water filling, and can have the hydraulic pressure that formed in first paragraph 21 and contend with, reduce the possibility destroying seepage tunnel 2 and related facility.Wherein this second end blows rear formation is the opening 223 that taper is outwards carried out, and its objective is the possibility of wishing that minimizing opening 223 is hindered by ground.
Supplementary notes, comprehensive explosion is herein the mode taked from outside to inside, from as tunneling mode from inside to outside different.The explosion of explosive need retain on uncrossed " scope of freedom ", the direction that the rock after namely meaning retains explosion can be discharged.General tunneling or as this tunnel 20 digs the process of the second end 28, the order of igniting after explosive is set be by tunnel internal first, rock is made to be able to towards the uncrossed discharge of tunnel internal, ignite outside again, namely compared with the explosive in the crag of depths, the ground blown is transported by last personnel again.Namely order from outside to inside is herein with marine direction for " scope of freedom ", by ground towards discharging, avoids the rock collapsed to hinder water inlet in the sea.Because after explosion, namely seawater pours in, personnel cannot enter again and remove ground, therefore must take detonation way from outside to inside.
When as shown in Figure 5 direct in second segment 22 water filling, if explosion failure, then the unit 4 that draws water is set to extract the water body injected in second segment 22, again carries out explosive setting, again after second segment 22 water filling, then explosion again.If but have security concerns, then this second segment 22 discarded, (unit 4 that draws water also can be arranged on ground to extract the water body of first paragraph 21, draw water with water pipe, this mode arranges not shown), again excavate separately in the same level degree of depth, another second segment (not shown) is set, repeatedly carry out until be successfully communicated with genuine 20 with high pressure waters 8, becoming can the seepage tunnel 2 of diversion.
The convenience having or be without caused difference operation of liaison tunnel 5, because personnel cannot walk after genuine water filling, need treat first paragraph draw water after personnel just can again be entered by ground, if there is liaison tunnel 5, and at access road 6, another auxiliary gate (not shown) is set to separate this tunnel 20 and this liaison tunnel 5, personnel can when still there is water filling in this tunnel 20 just at the bottom of ground (in this liaison tunnel 5) await orders, wait to draw water and completely just can carry out subsequent treatment immediately, motor-driven behaviour.If without liaison tunnel 5, then because personnel after water filling in genuine 20 cannot pass in and out the open and close that genuine 20 carry out regulating gate 3, therefore the control circuit of this gate 3 need be connected to face, land 7, so that personnel control on face, land 7.
In sum, behind Drilling tunnel 20, by least this first paragraph 21 water filling, can be communicated with second segment 22 and high pressure sea water during high pressure waters 8 have corresponding hydraulic pressure and contend with, reduce the possibility destroying seepage tunnel 2 and related facility, therefore really can reach object of the present invention.
As described above, be only preferred embodiment of the present invention, when not limiting scope of the invention process with this.
