Abstract
The utility model discloses a sand cushion structure for a high-water-content area in blowing and filling operation. The sand cushion structure for the high-water-content area in blowing and filling operation sequentially comprises a first medium-coarse sand layer, a first woven fabric layer, a first bamboo grid layer, a second medium-coarse sand layer, a second bamboo grid layer and a second woven fabric layer from top to bottom. The structure composed of the two woven fabric layers, the two bamboo grid layers and the two medium-coarse sand layers is adopted, and therefore the bearing capacity of a sand cushion layer and the water seepage prevention performance of the sand cushion layer are greatly improved. Due to the fact that the sand cushion structure is simple in structure and related materials are inexpensive, the manufacturing cost is low, and large-area popularization of the sand cushion structure is facilitated.
Description
Technical field
The utility model relates to high-moisture percentage in a kind of hydraulic reclamation operation zone sand cushion structure, relates in particular to the temporary road bed course that the operation mid-early stage of reclaiming land from the sea marches into the arena.
Background technology
High-moisture percentage zone sand cushion in the operation of tradition hydraulic reclamation, easily subside and seep water.Tracing it to its cause is mainly that the supporting capacity of sand cushion is poor, and thickness is not enough to prevent infiltration.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of can be simple in structure, relate to all high-moisture percentage zone sand cushion structures in hydraulic reclamation operation preferably of the lower and bearing capacity of cost and percolation-proof performance.
For this reason, the high-moisture percentage zone sand cushion structure in the hydraulic reclamation operation that the utility model provides, comprise the first medium-sand seam, the first base fabric, the first bamboo stratum reticulare, the second medium-sand seam, the second bamboo stratum reticulare and the second base fabric from top to bottom successively.
In the utility model, adopted double-deck woven cloth and bamboo web frame, and double-deck medium-sand seam, thereby the supporting capacity of sand cushion and percolation-proof performance are improved greatly, because the material that it is simple in structure and relate to is cheap material, so manufacturing cost is also lower, is conducive to spread.
The accompanying drawing explanation
The sectional schematic diagram of the high-moisture percentage zone sand cushion structure in the hydraulic reclamation operation that Fig. 1 provides for the utility model.
The specific embodiment
As shown in Figure 1, high-moisture percentage zone sand cushion structure in the hydraulic reclamation operation that the utility model provides, comprise successively the first medium-sand seam 1, the first base fabric 2, the first bamboo stratum reticulare 3, the second medium-sand seam 4, the second bamboo stratum reticulare 5 and the second base fabric 6 from top to bottom, each aspect all adopts the structure of stacked in multi-layers.Wherein, the thickness of the first medium-sand seam 1 is 150CM, and the thickness of described the second medium-sand seam 4 is 50CM.
Claims (2)
1. the zone of the high-moisture percentage in hydraulic reclamation operation sand cushion structure, is characterized in that: comprise successively the first medium-sand seam, the first base fabric, the first bamboo stratum reticulare, the second medium-sand seam, the second bamboo stratum reticulare and the second base fabric from top to bottom.
2. the high-moisture percentage in hydraulic reclamation operation according to claim 1 zone sand cushion structure, it is characterized in that: the thickness of described the first medium-sand seam is 150CM, the thickness of described the second medium-sand seam is 50CM.
