The sequence of construction of backfill provided by the present application and consolidation grouting telescoping steel form pre-embedment grouting pipe structure: bedrock surface is clear
Reason → underplate concrete pours → and side and roof arch reinforcement installation → telescoping steel form is in place → brushing release agent → seam surface treatment and measurement
Setting-out → waterstop installation → locking plug template closure → template check → pre-embedment grouting pipe → concreting → waits strong → demoulding
Maintenance → subsequent cycle.
In order to which structure provided by the present application is described in detail, below in the Tasha A Er water-control project power tunnel barrel work
Concrete application in journey is illustrated.
The Xinjiang Tasha A Er water-control project power tunnel barrel engineering construction bid section, concrete engineering construction project are as follows:
I # power tunnel barrel pile No. sends out 1+395.087m~hair 5+979.529m section concrete lining cutting, lining cutting overall length 4584.442m；Ⅱ#
Power tunnel pile No. sends out 1+409.861m~hair 5+962.939m section concrete lining cutting, lining cutting overall length 4553.078m；1# and 2# power generation
Hole working tunnel closure etc..Section is diameter 8.5m round, longitudinal slope 0.2%, III class after two power tunnel barrel concrete linings
Lining thickness 40cm under the conditions of wall rock geology, lining thickness 60cm under IV, V class surrounding rock geological conditions.The main work of concrete works
Cheng Liang are as follows: 12.98 ten thousand m3 of concrete lining, reinforcing bar system pacify 2.31 ten thousand t.
When making telescoping steel form, preformed hole is arranged according to design requirement on punching block.Aperture Φ 60mm, in favor of Φ 50
Steel pipe insertion.6 row's preformed holes are arranged on punching block altogether.First row is 1.0m away from trolley port, remaining spacing is 2m.Preformed hole is plum
Flower-shape arrangement.
The installation site of steel pipe embedded part controls stake wheelbase using total station setting-out by design drawing, forms control net,
To control embedded steel tube position, array pitch uses steel ruler setting-out between grout hole.Telescoping steel form pre-embedment grouting pipe nozzle blocks,
Reserved nozzle is blocked using having a size of 15cm × 8cm, is covered with a thickness of the steel plate of 3mm, and a thickness 5mm is welded on the steel plate,
The circular steel plate and link chain that radius is 2.5cm, to facilitate steel plate when closure to adjust, nozzle blocks steel plate and uses M12 spiral shell
Bolt is reinforced.
This engineering uses steel pipe to be up to 90% or more as grout hole built-in fitting utilization rate, the presentation quality of formation of concrete
It is substantially unaffected.Relative to common drill construction technique, need to repeatedly drill because of situations such as positioning inaccurate or chance reinforcing bar, coagulation
Native surface is destroyed, caused by repairing and rework cost accordingly reduce 90% or more.
Compared with pvc pipe built-in fitting, reinforces positioning and be guaranteed.Meanwhile interference of the pore-creating to steel mesh is avoided, it makes
The efficiency in hole improves 50% or more, has saved construction cost.
From social benefit, power tunnel barrel engineering mainly undertakes diversion task, using telescoping steel form and grouting steel pipe
The application of pre-buried technology, is improved this engineering construction quality, while also just improving the safety system of power tunnel barrel engineering
Number, provides guarantee for reservoir safety.
Telescoping steel form hole serves as a contrast the application of concrete and the pre-buried technology of grouting steel pipe, be similar engineering in Engineering Construction Management and
It summarizes in terms of quality control on construction and has accumulated engineering experience, cultivated a collection of technical staff for skillfully grasping this technology and pipe
Reason personnel provide technical support for later similar engineering project construction.Meanwhile telescoping steel form is carried out in this construction process
Local flow improvement, cavern's construction of concrete lining is innovated, for similar engineering make full use of telescoping steel form globality,
Mobility shortens the construction period, save the cost provides reliable method.
The Tasha A Er water-control project power tunnel barrel engineering carries out power tunnel concrete lining using telescoping steel form
Construction, accelerates construction speed, has saved cost, meanwhile, by carrying out innovation transformation to telescoping steel form, make full use of punching block platform
The globality and mobility of vehicle are realized to the one-time formed effect of concrete construction.Grouting pore-creating is substituted using embedded steel tube,
Grouting pore-creating destruction caused by concrete is greatly reduced, ensure that construction quality.This engineering combine using telescoping steel form and
Both pre-buried grouting steel pipes advantage simultaneously carries out innovation and application, is compared compared with other similar projects using traditional handicraft construction, engineering is applied
Working medium amount and comprehensive benefit significantly improve.
In short, backfill provided by the present application and consolidation grouting telescoping steel form pre-embedment grouting pipe structure, simple and reasonable,
It is easy to install and use.By arranging preformed hole in telescoping steel form template, and reserved grouting hole plugging device, later-stage utilization are set
Embedded steel tube substitution grouting pore-creating, carries out backfill and consolidation grouting construction, can reduce pore-creating process, and can prevent mixed to molding
The destruction for coagulating soil effectively improves the construction quality of hole lining concrete.Final power tunnel barrel engineering uses crawler belt voluntarily trestle type
Needle beam wholecircle telescoping steel form carries out lining cutting, and backfill and consolidation grouting pore-creating use steel pipe built-in process.
