Description
Technical field
The present invention relates to hydraulic and hydroelectric engineering technical field, specifically a kind of tunnel penstock lower concrete construction dress
It sets.
Background technique
In Construction for Hydroelectric Project, it is hit tunnel, such as water conservancy there are various functional or structural large-scale overpressure resistants
Diversion tunnel in hydroelectric project, usual pressure resistance, which is hit, the installation of penstock after tunnel excavation, and pressure steel
Pipe all needs to carry out the construction of penstock steel lining concrete after being installed, with maturation and the development of the prior art, at present mostly
Number pressure resistances are hit tunnel penstock steel lining using intensity is higher, mobility and the preferable self-compacting concrete of workability are applied
Work.Often due to design structure reinforcing bar comparatively dense in the construction of penstock lower concrete, concrete construction operating space is narrow
Narrow, hose vibrator can not vibrate under the effect of gravity along penstock bottom arcwall face, the constructional difficulties that cause to vibrate, no
Uniformly, not in time the problems such as, causes stress steel pipe bottom and pours that not full, rate of coming to nothing is larger, to the normal operation of penstock
Threaten larger, and construction efficiency is lower, investment it is artificial more, cause certain wasting of resources, and increase secondary construction cost
With.Therefore the problem of how overcome the deficiencies in the prior art is current hydraulic and hydroelectric engineering technical field urgent need to resolve.
Summary of the invention
It is an object of the present invention to solve the deficiency of the existing technology and provide a kind of tunnel penstock lower concretes to apply
Tooling is set, and is reduced penstock lower concrete and is come to nothing and rate and to move back sets the artificial labor intensity of hose vibrator, is reduced
Personnel investments, accelerate construction speed.
To achieve the above object, The technical solution adopted by the invention is as follows:
A kind of tunnel penstock lower concrete constructing device mainly includes penstock, penstock stiffening ring, indulges
To structure reinforcing bars, circumferential structure reinforcing bars, self-compacting concrete and vibrates and be oriented to cage；Penstock stiffening ring is in penstock
Outside, in the outer ring of penstock stiffening ring, vertical structure reinforcing bar is axially disposed in self-compacting concrete circumferential structure reinforcing bars,
Circumferential structure reinforcing bars and vertical structure reinforcing bar binding and fixing vibrate and are oriented to cage setting in self-compacting concrete, with vertical structure
Reinforcement welding fixation and close penstock stiffening ring；Described vibrate is oriented to cage and connects group with circumferential round steel by longitudinal round steel
At.
Described vibrating is oriented to cage, can the concrete hose vibrator diameter according to used in scene manufacture accordingly
Diameter；It preferably vibrates and is oriented to cage ring to 6.5 round steel interannular of φ away from for 200mm.
Described vibrating is oriented to the annulus that cage ring is processed into diameter to 6.5 round steel of φ as 130mm, the guiding circle of cage longitudinal direction φ 10
Steel has 8, angle arrangement at 45 °.
Described is to vibrate to be oriented to the inside that cage longitudinal direction round steel is welded in circumferential round steel ring.
Described is to vibrate to be oriented to cage arc length in 60 ° of arm of angle lines of tunnel.
The present invention be applied to large-scale overpressure resistant be hit tunnel penstock lower concrete construction, tunnel penstock bottom
When concrete construction, installation vibrates and is oriented to cage by penstock bottom structure reinforcing bar, hose vibrator along vibrate be oriented to cage into
Row vibrates, and largely improves the plumpness of concreting efficiency and penstock bottom.
Compared with prior art, the present invention has the advantages that:
1, existing concrete hose vibrator can not be vibrated along penstock bottom arcwall face and be changed by the device of the invention
It is oriented to cage into increase to vibrate and can vibrate along penstock bottom arcwall face, it is low to overcome construction efficiency, personnel's labour
Intensity is big, and time-consuming is taken a lot of work, and the problems such as being unevenly not thorough not in time of vibrating can reduce personnel's investment and labour through the invention
Intensity, increase concrete vibrating it is abundant, it is uniform with it is timely, improve the full of concreting speed and penstock bottom
Degree reduces penstock lower concrete and comes to nothing rate, reduces because of the larger production of penstock steel lining bottom concrete void rate
The risk of raw quadratic cost has saved construction cost, and more existing penstock steel lining concrete construction efficiency improves 30%, pressure
Power steel pipe steel lining bottom come to nothing rate reduce by 40%, preferably economic and social benefit can be generated.
2, the invention belongs to the scope that hydraulic and hydroelectric engineering technical field basis is changed, water conservancy and hydropower work will greatly be pushed
Progress of the stroke pressure steel pipe steel lining bottom concreting in terms of technique, efficiency, the document of tunnel concrete construction at home and abroad
In also have no relevant report.
3, the present invention yet there are no applies in Construction of Hydropower Engineering, is intended to reduce personnel's investment and reduces constructor
The labor intensity of member uniformly vibrates to penstock steel lining bottom concrete construction progress in time, reduces penstock steel lining
Lower concrete comes to nothing rate, improves efficiency, accelerates construction speed, there is higher application value.
