The specific embodiment
Like Figure 13 and shown in Figure 14, the horizontal consolidation grouting technique of the pressure regulation vertical shaft of existing routine generally all can adopt and set up the building scaffold pipe, set up the operation bed board (setting up one deck about every separated 2m), and drilling machine is installed.Job practices is the boring of manually-operated auger; The operating type of manually-operated grouting; This job practices has following drawback: 1. it is too big to set up the scaffolding work amount, not only will drop into materials such as scaffold and fastener in a large number in the construction, and will drop into human and material resources in a large number and install; Particularly large-scale vertical shaft, the expense of input is sizable.2. frequently shift work plane in the construction; This method shifts work plane speed and slowly (sets up scaffold on one side; Set up working platform on one side; On one side transfer equipment, equipment and personnel), cause the overlong time of construction, the surge shaft borehole wall horizontal consolidation grouting construction duration can not be satisfied total duration requirement of surge shaft Construction Plan under a lot of situation; 3. the more important thing is be difficult for to ensure operating personnel and equipment facility construction safety, particularly large-scale, construct that section is changeable, in the vertical shaft of complicated condition, equipment, the frequent transhipment of personnel are the hidden danger that causes security incident all might take place at any time.
A kind of embodiment as the utility model; To shown in Figure 12, a kind of vertical shaft borehole wall construction operation lift platform comprises operation trailer system and work lift platform system like Fig. 1; Said operation trailer system comprises some hoist engine 1, switch board 8, swings to pulley 3 and hoisting bracket 4; Said work lift platform system comprises lift platform 5, and lift platform 5 has been provided with weighty slider, and lift platform 5 is equipped with anti-skidding screw mandrel 6 of plurality of fixed and anti-frictional resistance wheel 7 along periphery.
Hoist engine is arranged at by the vertical shaft top, and hoist engine 1 is connected with switch board 8, and some groups of hoist engines 1 are by switch board 8 centralized operations, and the steel cable 2 of every group of hoist engine 1 is connected with a weighty slider with hoisting bracket 4 backs through swinging to pulley 3.Under switch board 8 operations, hoist engine 1 moves up and down in vertical shaft through steel cable 2 traction lift platforms 5.
Said lift platform 5; It is the working load carrying platform of work lift platform system, and all on this platform, lift platform 5 adopts i iron, channel-section steel and angle steel to process for staff and construction equipment, facility material; Comprise upper platform 51 and lower floor's platform 52; Upper platform 51 is the bed board frame, lays guidance tape above that, is assembled into working platform.Lower floor's platform 52 is a body frame, comprises radiation brace summer and centre frame, plays weighty slider and is arranged on lower floor's platform 52.
When lift platform 5 is fixed on that certain is a bit worked in the vertical shaft; Except the steel cable of hoist engine 12 is held lift platforms 5 can not move; The some groups of fixing anti-skidding screw mandrels 6 that the platform periphery is installed also prop up the borehole wall 9; It can make lift platform 5 horizontal location, and lift platform 5 can only be risen can not descend.Said fixing anti-skidding screw mandrel 6 is processed by shaped steel and round steel.Comprise screw mandrel 61, screw mandrel 61 1 ends are connected on the bearing 62 through bearing pin, and the other end connects friction locating piece 64 through bearing pin, and the polished rod place of screw mandrel 61 is socketed with gate seat 63, and bearing 62 all is welded on the lift platform 5 with gate seat 63.Adjustment screw mandrel 61 just can be through the friction locating piece 64 roof pressure boreholes wall 9 horizontal fixed lift platforms 5; When lift platform 5 has falling tendency, gate seat 63 is pushed down the polished rod of screw mandrel 61, because the friction locating piece 64 roof pressure boreholes wall 9; Whole lift platform 5 is lockable, and lift platform 5 can not glide; When lift platform 5 has up trend, owing to the hinged effect of screw mandrel 61, its polished rod and gate seat 63 are thrown off, and friction locating piece 64 unclamps with the borehole wall 9, and lift platform 5 is unrestricted.
Hoisting bracket 4 is the bracing frames of the steel cable 2 of hoist engine 1 being swung to the pulley of going into the well, and also is that platform has drawn the hanging point that weighty slider returns rope.Hoisting bracket 4 not still steel cable 2 swing to support, or platform load support bracket.Said hoisting bracket 4 is processed by materials such as shaped steel and steel plates; Comprise carrier base 41; Carrier base 41 is fixed on the borehole wall 9 through the anchor pole welded and installed at the vertical shaft top; Carrier base 41 is provided with pulley 42 and returns rope hanging point axle 43, and the steel cable 2 of hoist engine 1 is guided lift platform 5 into through pulley 42, and steel cable 2 returns on time rope hanging point axle 43 of restricting through the lifting movable pulley of lift platform.
Security test like the φ 22m in the power station, dark 171m, has in the pressure regulation vertical shaft borehole wall consolidation grouting engineering of gate shaft
Facility and material parameter calculating such as full design Selection hoist engine:
Main platform weight P1=20t (18t such as body frame and bed board, 2t such as screw mandrel and position-limited wheel).
Work live load P2=10t (comprising disk bit, an amount of drilling tool, staff etc.).
Hoist engine lifting force T1=(P1+ P2) * α=51t (the desirable 1.5-2 of safety factor α gets 1.7), 5 hoist engines of design arrangement, hoist engine adopt movable pulley to promote, and every hoist engine pulling force is T2=T1/5/2=5.1t.
Therefore select the hoist engine parameter for use: lifting force T2=5t, hold rope amount S=450m, reel rope speed V=7-9m, cable diameter φ 22mm (disrumpent feelings total pulling force＞300kN).
Carry additionally 5 5t bottle gouards moved by hands during the platform duty, safe pulling force can reach 75t, and safety factor reaches 2.5.
By above-mentioned visible, be very secure on the technology construction safety of application the utility model.
Use the utility model to carry out construction sequence: hoist engine 1 makes lift platform 5 segment distance that in vertical shaft, rises locate that (hoist engine 1 stops through steel cable 2 tractions; Fixing anti-skidding screw mandrel 6 props up the borehole wall 9) → staff's construction (pore-creating of borehole wall consolidation grouting engineering, cement injection mortar) → unclamp and fix anti-skidding screw mandrel 6; Cleaning platform periphery obstacle is made preparation → startup hoist engine 1 that lift platform 5 moves to next work plane lift platform 5 is drawn to next work plane.
Using the utility model construction hoisting support all is evenly to arrange along the borehole wall; Hoist engine 1 quantity is matched with it; Each towing point of lift platform 5 rising or falling speeds is balanced, synchronous; And rising difference and can being adjusted by switch board 8 operation of each hoist engine 1 so just can make lift platform 5 synchronous, balance liftings.
The design tractive force of operation trailer system is greater than more than 2 times of work lift platform system works total load; It is as safe as a house when therefore lift platform 5 is constructed; Can solve fully bigger, the job execution in the darker vertical shaft, the engineering quantity that runs into during like power station large-scale pressure regulation vertical shaft borehole wall consolidation grouting is big, the engineering time is long, the masty difficult problem of safety guarantee; Effective reduction of erection time and improve the efficient of consolidation grouting in the surge shaft, also cost saving investment greatly.
