Description
Technical field
The utility model relates to the working tunnel in a kind of water delivery engineering, is specifically related to a kind of working tunnel doubling as long distance water transfer tunnel surge shaft and maintenance access tunnel.
Background technology
In the hydraulic tunnel engineering adopting drill bursting construction, consider to slag tap, ventilate conveniently, reduction of erection time and investment, often arrange working tunnel in proper site, to play the effect of " hand-to-hand fight in tights of long hole ", connection earth's surface, working tunnel one end, one end connects water-conveyance tunnel, is the passage of Construction and Maintenance vehicle, equipment and constructor's turnover in the construction period, be also slag tap, ventilate, the passage of draining, after tunnel completion, often carrying out shutoff process with water-conveyance tunnel intersection.
Long distance pressure water conveyer tunnel problem of water hammer is the unfavorable factor affecting tunnel lining structural safety, for reducing water hammer to the destruction of lining cutting, general employing Structure of Surge Tank regulates hydraulic pressure, surge shaft is the passage of water hammer release, basic pattern is above tunnel, excavate formation in massif well formula or cavern's structure, the larger voltage regulation result of section is better, but corresponding engineering quantity and investment also larger.The vertical shaft type structure that existing long distance water transfer tunnel surge shaft is generally adjustment water hammer and designs, construction is complicated, and comprehensive utilization degree is lower.
The maintenance mode that water-conveyance tunnel is commonly used at present is the mode into people's maintenance, generally in working tunnel block section, bury steel pipe underground doubles as enter hole, steel pipe block section peripheral hardware silently, after tunnel emptying, open silently, personnel enter water-conveyance tunnel maintenance by pre-buried steel pipe, and maintenance vehicle and big-and-middle-sized equipment cannot enter water-conveyance tunnel by enter hole, and maintenance transportation work condition is poor.
Chinese patent CN201762695U discloses and is a kind ofly applicable to the structure that big-and-middle-sized plant equipment enters long tunnel for overhaul, diversion tunnel air vent is expanded and arranges that formation one size meets the service shaft well of big-and-middle-sized repair apparatus turnover, at the top surrounding concreting framed bent of vertical shaft, and on framed bent, cover prefabricated bridge to be opened/closed, this shaft structure has the function of ventilation, pressure regulation and maintenance traffic simultaneously, construction period also can be used as the passage of slagging tap, but the turnover of shaft structure maintenance vehicle arrangement needs special opening and closing device, and transportation condition is still poor.
Generally, existing Long tunnels is low to working tunnel producing level, has only played the traffic aisle function of construction period, and small part establishes steel bifurcated when completing shutoff, and the runtime is used as enter hole, and the traffic maintenance function played is limited.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of working tunnel being applicable to water-conveyance tunnel pressure regulation and maintenance traffic is provided, by rationally arranging working tunnel structure, on the one hand, working tunnel can be used as the surge shaft of runtime, on the other hand, and the traffic aisle of big-and-middle-sized maintenance vehicle or equipment turnover when can be used as overhauling, both expand the function of working tunnel, saved construction investment, turn improve degree of safety and the overhaul efficiency of water-conveyance tunnel operation.
The technical scheme that the utility model adopts is: a kind of working tunnel being applicable to water-conveyance tunnel pressure regulation and maintenance traffic, working tunnel is divided into inducer, barrel section and lower flat section successively from ground to water-conveyance tunnel, the connection ground, top of inducer, the tail end of flat section is communicated with water-conveyance tunnel down, working tunnel entirety is the adverse slope structure that import is high, inside is low, mainly slag tap according to construction in footpath, hole and lining device size is determined, considers that maintenance vehicles while passing is convenient, adopts city-gate section.At the bottom of inducer, elevation is higher than table the highest in working tunnel, to ensure that water body can not overflow when working tunnel plays simple-type surge shaft function; Inducer landform is lower, when elevation at the bottom of inducer is lower than table the highest in working tunnel, also can establish retaining box at hole, by closing retaining box, retaining box and working tunnel are combined to form closed interval, and working tunnel also can play the function of air cushion type pressure balance chamber.When water-conveyance tunnel emptying backstop sluice is opened, working tunnel is as the access path of maintenance vehicle.Barrel section is the hole section of working tunnel change of longitudinal grade, the discrepancy in elevation of working tunnel inducer and lower flat section is played a transition role, because the discrepancy in elevation of working tunnel inducer and lower flat section is usually larger, engineering quantity is saved for reducing working tunnel length, abrupt slope should be adopted, but be considered as builder's road need meet local longitudinal gradient be not more than 9%, average gradient is not more than the requirement of 7.5%, therefore generally adopts the gradient of 5% ~ 9%; At the bottom of flat section, elevation flushes with elevation at the bottom of water-conveyance tunnel down, mainly plays cushioning effect to entering hole maintenance vehicle, is conducive to the speed of a motor vehicle being reduced before maintenance vehicle enters water-conveyance tunnel turning after barrel section descending.
Frame type management house can be established in inducer hole, carries out closed management to working tunnel, and meets working tunnel ventilation requirement, and when retaining box is established at hole, retaining box can be combined in frame type management house and arrange.
When barrel segment length is larger, suitably opens up in flat slope barrel section and dig, lay-by is set, optimize transportation condition.
Flat section can arrange plane turning down, and working tunnel and water-conveyance tunnel are with intersect with large-angle, favourable to river conjunction structural safety.
Working tunnel 1 can arrange two or more on water-conveyance tunnel 2 simultaneously, plays the effect of pressure regulation gang of wells.
The beneficial effects of the utility model are:
1) working tunnel horizontal section is large, and voltage regulation result is good.Working tunnel is ramp structure, average gradient with 9% calculates, table or pressure-bearing water surface area can reach more than 10 times of same open test pit footpath shaft area, working tunnel average gradient is more slow, table or pressure-bearing water surface area are larger with the ratio with open test pit footpath shaft area, and adjustment water hammer effect is better.
2) multistage that needs that working tunnel can be constructed in conjunction with segmentation is simultaneously arranged, and the effect of pressure regulation gang of wells is played in segmentation pressure regulation.Water-conveyance tunnel considers " hand-to-hand fight in tights of long hole ", often arranges more working tunnel, selects the working tunnel retaining proper site as surge shaft, can playing the effect of segmentation pressure regulation, can protect tunnel better than arranging single surge shaft to water-conveyance tunnel.
3) runtime maintenance is very convenient.Because working tunnel inherently passes in and out the passage of water-conveyance tunnel, maintenance vehicle directly can sail into when discharging water maintenance, and relative vertical shaft opens and closes and vertically passes in and out mode, both safe and reliable, energy-conservation again, improves runtime overhaul efficiency.
