Abstract
The invention provides a method of construction for the seam or sealing of the water supply canal arrangement in the hydraulic engineering characterized by that, a seepage control film is laid on the trench interconnection of the separating beams in length and breadth on the slope and bottom of the canal along the direction of the transverse separating beam trench, a telescopic joint is formed by folding from the seepage control film on the trench bottom of the longitudinal separating beam trench along the direction of the trench, the two longitudinal sides of the seepage control film project the transverse separating beam trench by a length of 1-2m, placing concrete into the transverse separating beam trench, and placing longitudinal separating beam, repeating the construction procedures. The advantages of the invention are smooth seam seepage control film, fast welding speed and fine quality of welding.
Description
Technical field
The invention belongs to the seam of hydraulic engineering feeder channel structure or laying, the welding procedure method of the job practices of sealing, particularly seepage proof film.
Background technology
In order to solve the Stability Analysis of Structures problem of Gobi desert and location, desert channel, generally have longitudinally every beam and horizontal every beam in the side slope of large-scale water conservancy channel and bottom design.Vertical, horizontal constitutes stable framework every the mutual interconnection of beam, and precast concrete plank or block cement board in framework make at the bottom of the canal and side slope constitutes an overall structure.The anti-seepage channel of design is for will lay the anti-seepage geomembrane that one deck is connected as a single entity in longitudinal and transverse bottom and cement board bottom every beam.And to guarantee that the anti-seepage geomembrane seam tightly is very difficult.
Traditional job practices is to excavate longitudinal and transverse groove every beam at the bottom of the canal of moulding and on the side slope, and cast-in-place notes concrete constitutes longitudinal and transverse every beam in groove.Before the cast-in-place moulding of beam, lay anti-seepage geomembrane longitudinal and transverse in advance.Because the groove infall of the longitudinal and transverse beam that digs out forms multiaspect, polygon and polygonal, causes the anti-seepage geomembrane of laying to locate bending fold at this, in this case, tightly be very difficult with the seam crossing welding of anti-seepage geomembrane.Traditional welding procedure method can not guarantee the welding quality of anti-seepage geomembrane seam, and speed of welding is slow, often causes defective and repairs.
Summary of the invention: the object of the present invention is to provide a kind of laying, welding procedure method of seepage proof film, not only make the anti-seepage geomembrane seam that is laid on longitudinal and transverse beam infall smooth, solder joint is convenient, and speed of welding is fast, the work efficiency height, solder joint is tight, and welding quality is good.
The object of the present invention is achieved like this: a kind of laying of seepage proof film, welding procedure method, be included in the side slope of water conservancy channel and the longitudinal and transverse groove that the bottom is dug every beam, its step is 1, moves towards to lay anti-seepage geomembrane along the diaphragm groove every interconnection place of beam groove longitudinal and transverse, and the anti-seepage geomembrane that is positioned at the laying of mediastinum beam channel bottom is folded into along mediastinum beam groove trend
The length that shape expansion coupling, the vertical two ends of anti-seepage geomembrane stretch out the diaphragm groove respectively is 1-2m; 2, concreting forms diaphragm in the diaphragm groove of laying anti-seepage geomembrane; 3, will stretch out anti-seepage geomembrane that the diaphragm both sides are positioned at mediastinum beam groove position respectively
The shape expansion coupling is pulled out flattening, and the seam of the anti-seepage geomembrane of this anti-seepage geomembrane and adjacent flattening welds together; 4, concreting forms the mediastinum beam in the groove of the mediastinum beam of laying anti-seepage geomembrane; 5, when longitudinal and transverse groove every Liang Jiaochalianjiechu that the anti-seepage geomembrane of laying runs into that the next one digs, repeat above-mentioned welding procedure step.
Method of the present invention not only makes the anti-seepage geomembrane seam that is laid on longitudinal and transverse beam infall smooth, and solder joint is convenient, and speed of welding is fast, the work efficiency height, and solder joint is tight, the welding quality height.Method of the present invention has also been avoided laying anti-seepage geomembrane " T " font joint and " ten " font joint, has guaranteed welding quality.Solved the construction technology difficult point of place's disposable laying of anti-seepage geomembrane of longitudinal and transverse beam crosspoint and welding.Use the former design and the engineering structures of the constant journey of starting building of this method construction, do not increase construction costs, the one pair of weld seam in disposable shop do not intersect weld seam, solder joint, guaranteed welding quality to greatest extent.
Description of drawings
Fig. 1 is the channel cross sectional representation that is provided with antiseepage film, and Fig. 2 lays schematic diagram for vertical diaphragm right-angled intersection place antiseepage film, and Fig. 3 is Fig. 2 A-A sectional structure schematic diagram.
The specific embodiment
Anti-seepage channel cross sectional representation as shown in Figure 1, antiseepage film 2 are wrapped in the two sides and the bottom surface of mediastinum beam 3 and diaphragm 1, and are laid on the bottom surface of concrete slab 4.
The laying of concrete seepage proof film, welding procedure method are for to have dug longitudinal and transverse groove every beam in the side slope and the bottom of water conservancy channel, its step is as follows: 1, as Fig. 2, shown in Figure 3, move towards to lay anti-seepage geomembrane 2 along the diaphragm groove every interconnection place of beam groove longitudinal and transverse, anti-seepage geomembrane 2 is synthetic materials PE composite geo-membrane or PE geomembrane.The PE composite geo-membrane is the composite bed anti-seepage geomembrane that PE antiseepage film and nonwoven constitute.The anti-seepage geomembrane 2 that is positioned at the laying of mediastinum beam channel bottom is folded into along mediastinum beam groove trend
Shape expansion coupling 5, the bottom surface of expansion coupling 5 and mediastinum beam 3 bottom surfaces wide equating, the inside flanging length in its both sides equates with the height of mediastinum beam 3, makes
After shape expansion coupling 5 is opened, just in time wrap the two sides and the bottom surface of mediastinum beam 3.The length that the diaphragm groove is stretched out at anti-seepage geomembrane 2 vertical two ends respectively is 1.5m;
2, concreting forms diaphragm 1 in the diaphragm groove of laying anti-seepage geomembrane 2; 3, will stretch out anti-seepage geomembrane 2 that diaphragm 1 both sides are positioned at mediastinum beam groove position respectively
Shape expansion coupling 5 is pulled out flattening, and this anti-seepage geomembrane 2 welds together with the joint seal of the anti-seepage geomembrane 2 of adjacent flattening; 4, concreting forms mediastinum beam 3 in the groove of the mediastinum beam of laying anti-seepage geomembrane 2; 5, when longitudinal and transverse groove every Liang Jiaochalianjiechu that the anti-seepage geomembrane of laying 2 runs into that the next one digs, repeat above-mentioned welding procedure step.
