Abstract
The utility model relates to a kind ofly builds the secondary weir structure on barged-in fill, it is characterized in that: comprise directly on saturated dredger soft soil, along existing one-level sub-weir length direction hydraulic reclamation, the pan soil belt with one fixed width, the volume displaced of saturated dredger soft soil within the scope of pan soil belt can be realized, the filled geotube layer laid on pan soil belt top, on the sub-weir of clay that filled geotube layer is built, hydraulic reclamation pan soil can be directly adopted to build.Compared with prior art, the utility model has the advantage of: this form of structure is saved and laid reinforcement cushion, backfills medium coarse sand, sets the basement process operations such as plastic draining board, working procedure is simple, with low cost, barged-in fill can be constructed without the need to carrying out airing, greatly can improve efficiency of construction, the comprehensive utilization benefit that large-scale strand inhales ship can be improved.
Description
Technical field
The utility model relates to a kind of building and is building the sub-weir of the secondary on barged-in fill structure.
Background technology
Barged-in fill builds cofferdam, difficulty is very big, it is main because barged-in fill moisture content is large, bearing capacity is very low, in order to reach the object of build, often need to wait for certain airing time, and then geo-grid 1 ' is laid on barged-in fill, the reinforcement cushions such as bamboo basketry 2 ', shown in participation Fig. 1, and then fill out on reinforcement cushion and establish certain thickness sand cushion 3 ', to meet mechanical execution requirement, and then sand cushion and be provided with reinforcement cushion barged-in fill in plug band drain 4 ' and carry out basement process, last lay filled geotube 5 ' being inserted through above the sand cushion of band drain again, thus formation embankment.
Adopt such form of structure, often need the airing time of wait one section of barged-in fill, and working procedure is many, interference large, construction speed is very restricted.
Utility model content
Technical problem to be solved in the utility model provides a kind of working procedure simple for above-mentioned prior art, the secondary weir structure of building on barged-in fill with low cost.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind ofly build the secondary weir structure on barged-in fill, it is characterized in that: comprise directly on saturated dredger soft soil, along existing one-level sub-weir length direction hydraulic reclamation, the pan soil belt with one fixed width, the filled geotube layer laid on pan soil belt top, on the sub-weir of clay that filled geotube layer is built.
The outside side of described pan soil belt is skewed, and inhales ship direct hydraulic reclamation seabed pan soil by large-scale strand and formed
The section of described filled geotube layer is trapezoidal.
The section on the sub-weir of described clay also in trapezoidal, and adopts the pan soil of hydraulic reclamation to build.。
Compared with prior art, the utility model has the advantage of: this form of structure is saved and laid reinforcement cushion, backfills medium coarse sand, sets the basement process operations such as plastic draining board, working procedure is simple, with low cost, barged-in fill can be constructed without the need to carrying out airing, greatly can improve efficiency of construction, the comprehensive utilization benefit that large-scale strand inhales ship can be improved.Pan soil belt realizes the volume displaced of saturated dredger soft soil in coverage, and clay weir in top also can adopt the pan soil of hydraulic reclamation directly to build.
Accompanying drawing explanation
Fig. 1 is the profile of the form of structure of building the sub-weir of secondary in prior art on barged-in fill.
Fig. 2 is the profile of the secondary weir structure of building in the utility model embodiment on barged-in fill.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
The structure of building the sub-weir of secondary on barged-in fill as shown in Figure 2, it comprise directly on saturated dredger soft soil, along existing one-level sub-weir length direction hydraulic reclamation, the pan soil belt 1 with one fixed width, the filled geotube layer 2 laid on pan soil belt 1 top, builds the sub-weir 3 of clay at filled geotube layer.The outside side of pan soil belt 1 is skewed, and inhales ship direct hydraulic reclamation seabed pan soil by large-scale strand and formed, and outside inner side and the sub-weir of one-level, 4 fit, and therefore pan soil belt 1 realizes the volume displaced of saturated dredger soft soil in coverage.The section of filled geotube layer 2 is trapezoidal, and the section on the sub-weir of clay 3 is also in trapezoidal, and clay weir bottom width is less than filled geotube layer top width.
Claims (4)
