Description
Technical field
The present invention relates to a kind of shield machine working shaft lining wall trickle irrigation maintenance processes, belong to highway construction technology field.
Background technique
Lining wall early curing is not in place to cause body structure surface dehydration or rate of temperature fall too fast, can all produce to concrete structure
Raw adverse effect.Since wall is vertical structure, surface is unable to water storage, is difficult to ensure maintenance quality, a side with conventional maintenance
Face causes the dehydration of concrete wall surface too fast, and on the other hand conventional maintenance causes concrete cooling rate to accelerate, and causes to mix
The generation in Xtah Crude Clay structure crack.Usual manner is generally curing in the mold, sprinkling maintenance, the maintenance of brush curing agent, simply pastes film
Maintenance.Curing in the mold can reduce the template turnaround time, largely increase engineering cost；Sprinkling maintenance needs persistently to pour
Water keeps concrete to be in moisture state, constructs in Arid Area and hot weather, will cause great lot of water resources waste；Brush is supported
Shield agent maintenance has a higher requirement to the use selection of curing agent and brushing technology, by external action shadow after curing agent film forming
Sound is also easy to produce crackle, influences moistening effect；The film that single stickup membrane curing hangs on metope is not fixed easily, easy to damage, maintenance
Effect is poor.
Summary of the invention
In view of the above existing problems in the prior art, the present invention provides a kind of shield machine working shaft lining wall trickle irrigation maintenance sides
Method.
To achieve the goals above, a kind of shield machine working shaft lining wall trickle irrigation maintenance process that the present invention uses, including with
Lower step:
1) prepare maintenance water；
2) screw rod, flitch are installed on lining wall；
3) suspension maintenance water pipe, the one end and maintenance for conserving water pipe are connected with water, are opened maintenance valve, are soaked concrete surface；
Curing membrane is hung on flitch, the side mounting geotextiles outside curing membrane；
4) fixed metope geotextiles, are adjacent to metope.
In the step 1), maintenance water is filled in maintenance bucket.
Form removal after the completion of lining wall pours in the step 2, the pre-buried M16 nut at the top of wall install screw rod,
Then spiro rod length >=10cm, spacing 1.5m install 5cm × 5cm flitch on screw rod top.
PVC maintenance water pipe is subjected to aperture according to spacing for 30cm in the step 3), the water pipe of aperture is suspended on spiral shell
Below bar, water pipe hole location is made to be directed at wall side.
In the step 3), the curing membrane that uses is thickness is smaller and the film of flexible.
In the step 4), the upper end of geotextiles is wound in another flitch, which is followed closely into the flitch above screw rod
On, geotextiles lower end is transferred to wall bottom, is fixed on the pre-buried rotary table nut of base opening.
Compared with prior art, the invention has the following beneficial effects:
After 1. maintenance tool of the invention is installed, it is no longer necessary to which artificial watering, maintenance personnel need to only pay close attention in maintenance bucket
Maintenance water storage, greatly reduce the workload of maintenance personnel, also avoid maintenance personnel dereliction of duty cause wall support
The phenomenon that shield is interrupted.
2. surface of wall curing water of the present invention number, can by adjust maintenance valve be controlled, it is ensured that concrete
Surface wettability, and flowed out without a large amount of water.
3. it is of the invention by the way that moisturizing can be carried out in curing membrane outer side covering geotextiles, while can be to avoid because of sunlight
The situation that direct projection causes concrete temperature excessively high.
4. a possibility that metope maintenance tool of the invention wrecks is small, all for can circulation material, and letter convenient for disassembly and assembly
It is single, reduce project input cost.
Specific embodiment
In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention is carried out below further detailed
It describes in detail bright.However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention, it is not limited to this hair
Bright range.
Unless otherwise defined, all technical terms and scientific terms used herein are led with technology of the invention is belonged to
The normally understood meaning of the technical staff in domain is identical, and term as used herein in the specification of the present invention is intended merely to retouch
State the purpose of specific embodiment, it is not intended that in the limitation present invention.
A kind of shield machine working shaft lining wall trickle irrigation maintenance process, comprising the following steps:
1) prepare maintenance water；
2) screw rod, flitch are installed on lining wall；
3) suspension maintenance water pipe, the one end and maintenance for conserving water pipe are connected with water, are opened maintenance valve, are soaked concrete surface；
Curing membrane is hung on flitch, the side mounting geotextiles outside curing membrane；
4) fixed metope geotextiles, are adjacent to metope.
In the step 1), maintenance water is filled in maintenance bucket.
Form removal after the completion of lining wall pours in the step 2, the pre-buried M16 nut at the top of wall install screw rod,
Then spiro rod length >=10cm, spacing 1.5m install 5cm × 5cm flitch on screw rod top.
PVC maintenance water pipe is subjected to aperture according to spacing for 30cm in the step 3), the water pipe of aperture is suspended on spiral shell
