Abstract
The utility model discloses the large sand pocket of a kind of controllability, comprise bag, it is characterized in that: in described bag, be intervally distributed with many ropes, the two ends of every rope are connected with lower wall with the upper wall of bag respectively, and described many ropes are arranged in a row by the end to end of bag; More than rope is provided with two rows; Described bag is to be made by the polypropylene filament yarn woven geotextile of 300g/ ㎡; 3 road polyamide fibre sewer are selected in the stitching portion of described bag; Folding 3 layers of stitching portion, width is 5～10cm; The width of described bag is not less than 16m.Owing to adopting above-mentioned form of structure, in described bag, be intervally distributed with many ropes, described rope is arranged in a row along the end to end of bag, can control the sand height that fills of large sand pocket like this, open sand pump fills in the operation of sand in bag, effect due to rope, makes sand pocket full closely knit, and arriving 80% above plumpness and single zone compaction thickness is 0.5 ~ 0.7m requirement.
Description
Technical field
The utility model relates to a kind of pipe bag of the use of building a dam, and specifically a kind ofly fills the large sand pocket that sand is used.
Background technology
Just filling sand mo(u)ld bag dam construction technique; refer to the mould bag that woven cloth is sewn into certain size; the reserved Sha Kou that fills of top layer; adopt waterpower or mechanical system; with certain pressure, fetch earth on the spot and be filled into mould bag and form and to fill sand pocket; excessive moisture can leach from geotextiles hole, and powder fine sand forms the sand material of denser under deadweight and seepage pressure effect, by sand pocket, is stacked into dike; Build a kind of dykes and dams that overcoat forms outward.Knitting bagged back-up sand ramp type embankment structure is due to design theory and construction technology comparative maturity, its construction costs is low, construction working face is large, speed is fast, to soft foundation is adaptable, relative, can gather materials on the spot and the advantage such as aboundresources, is widely used more and more structure sediment being required undemanding object of construction production particularly reclaiming fields from the sea in engineering.
After sand washing, with manually packed sand being jammed on, accelerate the fixed of packed sand, consider that packed sand is medium coarse sand, jam on after 5 minutes, if packed sand does not reach 80% plumpness requirement, need carry out secondary and charge.The sand filling thickness of sand filling bag should not be less than 0.5m, but should not be greater than 0.7m yet.
Between upper wall in existing large sand pocket or sandstone charging pipe bag and lower wall, there is no connection cord, so when filling sand, can make unavoidably sand amount fill too much, make sand filling thickness be greater than 0.7m, thereby affect the workmanship of embankment.
Summary of the invention
The purpose of this utility model is to provide the large sand pocket of a kind of controllability that sandstone charging amount is control effectively.
For achieving the above object, the technical scheme that the utility model adopts is:
The large sand pocket of controllability, comprises bag, it is characterized in that: in described bag, be intervally distributed with many ropes, the two ends of every rope are connected with lower wall with the upper wall of bag respectively, and described many ropes are arranged in a row by the end to end of bag.
More than described rope is provided with two rows.
Described bag is to be made by the polypropylene filament yarn woven geotextile of 300g/ ㎡.3 road polyamide fibre sewer are selected in the stitching portion of described bag; Folding 3 layers of stitching portion, width is 5～10cm.
The stitching portion of described bag adopts cementing agent bonding, and adhesive segment width is 10cm.
The width of described bag is not less than 16m.
The beneficial effects of the utility model: owing to adopting above-mentioned form of structure, in described bag, be intervally distributed with many ropes, described many ropes are arranged in a row by the end to end of bag, can control the sand height that fills of large sand pocket like this, open sand pump fills in the operation of sand in bag, effect due to rope, makes sand pocket full closely knit, and arriving 80% above plumpness and single zone compaction thickness is 0.5 ~ 0.7m requirement.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the lateral view shown in Fig. 1.
In figure: 1, bag; 2, rope; 3, upper wall; 4, lower wall.
The specific embodiment
As shown in Figure 1, 2, the large sand pocket of controllability, comprises bag 1, is intervally distributed with many ropes 2 in described bag, and the two ends of every rope are connected with lower wall 4 with the upper wall 3 of bag respectively, and described many ropes are arranged in a row by the end to end of bag.Described rope is provided with two rows.
Described bag is to be made by the polypropylene filament yarn woven geotextile of 300g/ ㎡, and 3 road polyamide fibre sewer are selected in the stitching portion of described bag; Folding 3 layers of stitching portion, width is 5～10cm.The width of described bag is not less than 16m.
The production technology of the large sand pocket of controllability is as follows:
Batching: the large sand pocket of controllability adopts the polypropylene filament yarn woven geotextile of 300g/ ㎡, and its technical indicator will meet the requirement of technical specification book.
Spell width: the scale that plant produced is good is arranged through after the assay was approved, can setting-out carry out processing, according to designing requirement, prepare burden, first measure single width and arrange, then carry out socketing of width and width and make.Polyamide fibre sewer is selected in bagging splicing, folding 3 layers of stitching portion, and width is 5～10cm approximately, seam 3 diatoms; Or adopt cementing agent bonding, and adhesive segment width is 10cm, every intensity index of bonded part is greater than 90% of bagging intensity.The large sand pocket of controllability be produced on produce in factory.
The connection of rope: upper wall and the lower wall at bag made in the two ends of rope, be sewed with altogether two rows.
Bundling: by the large sand pocket of the controllability after making bundling after the assay was approved, during bundling along fill bag axially and make cuff towards on be rolled into a bundle, then with nonwoven parcel with anti-tamper.Mould bag after bundling will be numbered warehouse-in or be gone out to transport to job site.
Polypropylene woven thing is through the aging reduction of ultraviolet long-term irradiation intensity meeting, therefore require bagging to have certain ageing resistance, the intensity index under its sunlight in exposed 3 months is not less than 80%, and raw material avoid ultraviolet ray to irradiate in transportation and storage process.
The above is preferred embodiment of the present utility model; certainly can not limit with this interest field of the utility model; should be understood that; for those skilled in the art; the technical solution of the utility model is modified or is equal to replacement, do not depart from the protection domain of technical solutions of the utility model.
