Abstract
The invention discloses a rapid construction method for a seepage-proof dam of a salt pan. The rapid construction method specifically includes firstly, digging a foundation trench; secondly, putting a seepage-proof material to the bottom of the foundation trench, and filling the foundation trench with earth and grinding the earth; thirdly, directly lifting the seepage-proof material to a designed lift height after grinding; finally, earthing up and grinding synchronously on two sides of the seepage-proof material. The construction process includes the steps of foundation trench digging, filming, foundation trench filling, film lifting, earthing-up, grinding, re-earthing-up and re-grinding, and the conventional earth surface construction process, including earthing-up, grinding and film turning, for the seepage-proof dam is changed into earthing-up and grinding, so that process is simplified, construction period is shortened, extruding and folding of the seepage-proof material due to the action of natural angle of repose of the earth during layered and staggered earthling-up and grinding can be avoided, loss of the seepage-proof material is reduced, and construction cost of the seepage-proof dam is saved.
Description
Technical field
The present invention relates to antiseepage dam, a kind of salt pan construction method, relate in particular to a kind of antiseepage dam, salt pan fast construction method containing impervious material.
Background technology
Antiseepage dam, existing salt pan is built in and completes after foundation trench, then adopt the stagger mode that rolls of layering dam body is carried out repeatedly to earthing to roll in impervious material both sides, master operation is for digging foundation trench-lower film-fill out foundation trench-earthing-roll-turn over film-earthing again-roll-turn over film, this mode is completing after foundation trench, build dam operation for turning over film-earthing-roll, not only procedure connection is more complicated, and because being staggers and rolls in the layering of impervious material both sides, cause impervious material run-off the straight under the effect of each stratified soil natural repose angle, paving mode when paving mode when the paving mode of impervious material designs as shown in Figure 1 becomes the practice of construction shown in Fig. 2, therefore many consumptions impervious material 20-40% when practice of construction is than design, cause the significant wastage of artificial material, improved the cost on antiseepage dam simultaneously.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of procedure connection relatively simple, can save impervious material, reduces antiseepage dam, the salt pan fast construction method of antiseepage dam cost.
The technical solution adopted for the present invention to solve the technical problems is: antiseepage dam, a kind of salt pan fast construction method, and its construction process is for digging foundation trench-lower film-fill out foundation trench-lift film-earthing-roll-earthing again-roll again, and concrete steps are:
First dig foundation trench, dig after foundation trench, transfer impervious material from earth's surface (as plastic-coated canvas, geotextiles, HDPE film etc., in construction, also can be referred to as " film ") be connected to bottom foundation trench, then foundation trench is banketed and rolled, after having rolled, the close position of transferring impervious material on earth's surface, install a series of by pullover along the assembling of moving towards of transferring impervious material, extension bar, be embedded with the articulated section of plumb aligner, the tail bone linking together with articulated section, and the supporting rod of clip composition, when assembling is installed, first tail bone is inserted to earth's surface, then the external screw thread of articulated section is connected to the internal thread of extension bar lower end, pullover internal thread is connected to the external screw thread of extension bar upper end, then connect the pullover becket bridle of each supporting rod with hawser, then by extension bar and be connected to the pullover righting on extension bar, when righting, to be embedded in plumb aligner on articulated section as reference, in the time that the colored bulb in plumb aligner is parallel with two benchmark grooves, think supporting rod righting, then use clip seizing hinge in articulated section, and hawser two ends are strained and fixed, then tied a knot in stay cord one end, pinch out the clamp holder of proboscis folder, stinging head-clamp with the proboscis of proboscis folder lives after impervious material, the lacing hole that one end that stay cord is not tied a knot presss from both sides through proboscis is also walked around hawser, pulling down stay cord lifts impervious material to design height, then in impervious material both sides, synchronous layered earthing rolls simultaneously, after having rolled, reclaim supporting rod, proboscis folder, hawser and stay cord.
Further, supporting rod is installed one group along the trend of transferring impervious material every the assembling of 50-100 rice, and the proboscis that is installed with stay cord is clipped on hawser arranges one every 8-12 rice (preferably 10 meters).
Further, the situation of too loosening for earth's surface soil property, by be positioned at plan to build wedge angle rope on pullover of the supporting rod at two ends, antiseepage dam and by rope on ground piling reinforce.
One section of extension bar preferred length is 2 meters, lifts height according to the ground of the impervious material of design, rationally determines extension bar hop count.
For antiseepage dam, salt pan construction site vegetation sparse, lack trees, and the higher feature of design hoisting depth of film, in order to lift quickly and easily impervious material, the present invention is by supporting a whole set of impervious material handle system, comprise supporting rod, proboscis rope clamp, hawser, stay cord etc., can lift impervious material rapid large-area, realize antiseepage dam, salt pan fast construction.
Compared with prior art, the present invention has the following advantages:
(1) construction process of above ground, antiseepage dam, salt pan part is become and lifts film-earthing-roll-earthing again-roll again from turning over film-earthing-roll-turn over film-earthing again-roll again, circulating process becomes earthing-roll two steps from earthing-roll-turn over film three steps, simplify operation, thereby shortened antiseepage dam construction duration;
(2) before layering earthing rolls, impervious material is directly lifted to design attitude, can avoid the layering of impervious material both sides stagger earthing while rolling because native natural repose angle effect is folding to the extruding of impervious material, thereby reduce the loss of impervious material, the cost of saving antiseepage dam.
In sum, when the present invention can effectively solve the dam of salt pan antiseepage in the past and builds, long and layering earthing of complex procedures, duration rolls the problem of pushing a large amount of losses of impervious material that impervious material brings while turning over film.Through estimation, the present invention can reduce the consumption 20-40% left and right of impervious material in practice, the expenditure of construction on every kilometer of antiseepage dam can be saved ten thousand yuan of left and right of 10-20 and (consider reusing of membrane system, actual expense of saving will be more), do not affecting under the prerequisite of workmanship, both reduced the duration, reduced again investment.
