Abstract
The utility model discloses a ground sand pebble revetment. The ground sand pebble revetment is characterized in that a ground sand pebble layer is laid on a bank slope between a riverway and a flood-preventing wall on a water side bank, an inverted filter covers the ground sand pebble layer, and dry stone paving is built on the inverted filter. The largest layering thickness of the ground sand pebble layer is not larger than 1m, and the relative density of the ground sand pebble layer should not be lower than 0.75. Thus, the bank slope of a city blood-preventing project can be kept stable, meanwhile, the occupied area and the investment of the project are reduced, and city flood-preventing requirements are also met.
Description
Technical field
The utility model relates to the urban flood defence shore protection, especially relates to a kind of sandy gravel shore protection that rolls.
Background technology
In flood control works, the stable of bank slope is the important component part of flood control works.The bank stability of flood control works, be related to the safety problem of whole flood control works.Flood control works is stable for construction work on the bank, generally bank slope is cut to slope or do barricade to guarantee the stable of bank slope.Bank slope is cut to slope and can take more land area, and city to increase as much as possible again land use area when exploitation, just there will be contradiction between the two; To bank slope, adopt the mode of doing barricade to guarantee that the stable of bank slope can make again the investment of flood control works greatly increase.
Summary of the invention
The purpose of this utility model be to provide a kind of bank slope that makes flood control works keep stable, not only reduce project occupation of land area and construction investment, but also meet that urban flood defence requires roll the sandy gravel shore protection.
The purpose of this utility model is achieved in that
A kind of sandy gravel shore protection that rolls, feature is: the bank slope upper berth between river course and waterside flood control body of wall on the bank is lined with one deck and rolls sand pebble layer, in the top of rolling sand pebble layer, is coated with loaded filter, in the top of loaded filter, builds dry stone pitching is arranged.
The maximum lift height that rolls sand pebble layer is not more than one meter, and roll the relative density of sand pebble layer should be lower than 0.75.
The utility model is that the sandy gravel that the bank slope upper berth between river course and waterside flood control body of wall on the bank is lined with the certain grating of one deck is reinforced bank slope, and the Cast-in-situ Piles in Sand-filling cobble is carried out to back-filling in layers, carry out grinding compacting, the maximum lift height that rolls sand pebble layer after rolling is not more than one meter, and the relative density that rolls sand pebble layer should be lower than 0.75, then be coated with loaded filter in the top of rolling sand pebble layer, build the placed rockfill bank protection is arranged in the top of loaded filter, can make like this bank slope of flood control works keep stable, project occupation of land area and construction investment have been reduced simultaneously, also meet the urban flood defence requirement.
The accompanying drawing explanation
Fig. 1 is sectional drawing of the present utility model.
The specific embodiment
Below in conjunction with example and contrast accompanying drawing the utility model is described in further detail.
A kind of sandy gravel shore protection that rolls, bank slope 2 upper berths between river course 3 and waterside flood control body of wall 1 on the bank are lined with one deck and roll sand pebble layer 4, be coated with the loaded filter 5 of being made by geotextiles in the top of rolling sand pebble layer 4, in the top of loaded filter 5, build dry stone pitching 6 is arranged.
The maximum lift height that rolls sand pebble layer 4 is not more than one meter, and roll the relative density of sand pebble layer 4 should be lower than 0.75.
Claims (2)
1. one kind is rolled the sandy gravel shore protection, it is characterized in that: the bank slope upper berth between river course and waterside flood control body of wall on the bank is lined with one deck and rolls sand pebble layer, in the top of rolling sand pebble layer, is coated with loaded filter, in the top of loaded filter, builds dry stone pitching is arranged.
2. the sandy gravel shore protection that rolls according to claim 1, it is characterized in that: the maximum lift height that rolls sand pebble layer is not more than one meter, and roll the relative density of sand pebble layer should be lower than 0.75.
