Technical field
The invention belongs to hydraulic engineering waterproof construction technology fields, and more specifically more particularly to a kind of hydraulic engineering is anti-
Water construction method.
Background technique
Sharp engineering is one of current highly important infrastructure project.It is related to during water conservancy construction much more very
Process and construction procedure.Wherein an important ring is waterproofing work.It, generally can be along road direction in irrigation and water conservancy work progress
Flume is arranged, so that peasant easily uses.Water flow is flowed along channel direction in flume.If water in flume compared with
It is more, may be to exosmosis, penetration range is wider, it is possible to cause the soft of road foundation, be unfavorable for the peace of vehicle on road
Full traveling.In particular for some Important Sections, waterproofing work is particularly important.
For this purpose, application No. is CN201710726324.7 to disclose a kind of hydraulic engineering waterproof construction method, belong to water conservancy
Engineering field, including step：Excavate groove：The groove that being used to, waterproof membrane and flume are set is excavated beside road, makes groove
In rectangular configuration, groove forms top plane, side elevation and baseplane；Plane is wherein pushed up close to the roadbed of road and lower than road
Road surface；Water-tight device is set：It is laid with waterproof membrane at groove, make a part fitting side elevation of waterproof membrane and forms vertical section,
A part fitting baseplane of waterproof membrane is set to form horizontal segment；Backfill：It bankets into groove and covers waterproof membrane, and reserved placement
The position of flume；Flume construction：Flume is set at reserved position, gap is filled and led up, and by soil compaction.This water
Sharp engineering waterproofing construction method can be to playing good waterproof action between flume and road.It can be widely applied for farmland
The occasions such as water conservancy, road water conservancy, bridge opening, tunnel.
But above scheme still has certain defect, long construction period, engineering construction intensity is low, and lacking has centainly
Limitation.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of hydraulic engineering waterproof proposed is applied
Work method.
To achieve the above object, the present invention provides the following technical solutions：A kind of hydraulic engineering waterproof provided by the invention is applied

S6：Pour C20
a：When pouring basis, elevation line is popped up on the both side plate of foundation trench in advance, with elevation control size, surpasses error not
3 percent are crossed, the construction method poured using segmentation, every segment length control is arranged in 6-8m distance every section of junction portion
Vertical template baffle plate pours C20 along foundation length direction paragraph by paragraph, so that foundation bottom is constituted continuous basic bottom beam, wherein shaking
Dynamic stick inserts point with quincunx insertion, and spacing 30-50cm when vibrating, " fast to insert ", " pulling out slowly ", to prevent coagulation scholar surface from first shaking
It is real, and layering, segregation phenomenon occur for lower surface concrete, when preventing from pulling out fastly, concrete has little time to supplement, leaving space, vibrating head insertion
It should be twitched up and down after concrete, amplitude 5-10cm, to exclude air in concrete, when vibration no longer sinks depending on concrete surface in level, no
Occurs bubble again, surface glows grey pulp-water, and vibrating head does not allow to control and reserve between vibrating head and template against template when vibrating
At least spacing of 40cm avoids vibrating head collision slab；
b：Staying for built-in fitting is set, and built-in fitting is embedded bar anchor, and built-in fitting is made pre- using being directly welded on structural member reinforcing bar
Embedded part and structure reinforcing bars firm welding guarantee that pre-buried size meets drawing requirement, reserved opening, and make pipe of concrete and reserved
Hole docking makes wooden frame mould according to design size, and after the installation of frame mould, receiving forms after pouring, and hole surrounding has reinforced reinforcing bar,
After pouring, mark warning sign is inserted, quiescing personnel construct in warning alert at least 36 hours；
S7：After C20 molding, cleared up by form removable, and to the basic bottom beam of construction site；
S8：Armored concrete upper surface after molding carries out the construction of Waterproof structural course, waterproof knot in the step S7
Structure layer is to be allowed to hardening in the coating film waterproof material that hard layer surface applies to form film waterproof material, and hard layer is made of metal steel
It is anti-to form film in hard layer coating film waterproof material, after hardening for one of plate, nonmetallic rigid plastics processed or bentonite plate
Water layer, quiescing personnel construct in warning alert at least 24 hours after coating film waterproof material, guarantee waterproof layer Forming Quality；
S9：Testing staff carries out waterproof performance test and examination, is strictly carried out an acceptance inspection according to examination article.
Technical effect and advantage of the invention：A kind of hydraulic engineering waterproof construction method of the present invention, changes traditional waterproof
Construction method first confirms that construction area, and the preparation for then carrying out material and facility passes through in earth excavation work progress
Intercom communication apparatus is communicated, and earth excavation is once completed, and work efficiency is high, is shortened the construction period, in backfill work progress
In, the soil that backfill uses the digging in-situ earthwork to generate economizes on resources, and reduces the earthwork transporting cost, and point three layers of backfill are mechanical
Lay a good foundation is more stable, and in the work progress of formwork for placing, construction personnel carries out grid cage production, testing staff at the scene
Next step process construction is carried out after acceptance(check) again, underlying strength is high, then long service life carries out pouring C20 and built-in fitting
Construction, using the construction method that pours of segmentation, good forming effect, after C20 molding, then by form removable, and to construction site
Basic bottom beam cleared up, Waterproof structural course be the coating film waterproof material that hard layer surface apply be allowed to harden form film
Waterproof layer, good water-proof effect finally strictly carry out an acceptance inspection according to examination article, and short time limit is suitble to promote the use of.
