Description

Provisional protection method for highway sea sand roadbed side slope
Technical field
The present invention relates to a kind of provisional protection methods for highway sea sand roadbed side slope.
Background technique
Highway is quickly grown in countries in the world at present, is the inevitable outcome of economic development, and highway milimeter number is long, Engineering construction region passes through various geology and geomorphologies, such as region of no relief, low hilly area and marshland, since land resource is limited, high speed Highway fills the highway for being difficult to obtain with soil, and closing on seashore, has sea sand resources abundant, therefore fill using sea sand The express highway roadbed first choice as expressway works construction, to economize the land resource.But since sea sand material is loose, stick poly- Power very little, and close on that the long-term rainfall in seashore region is very rich mostly, the sea sand filled is easy to form ditch by rain drop erosion Gully repairs difficulty.Therefore in expressway works construction, how effectively to carry out sea sand roadbed side slope and protect to pass weight It wants, few as the road event of roadbed filling using sea sand material at present, still mature sea sand roadbed side slope is not prevented temporarily The method of shield can be used for reference.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of provisional protections for highway sea sand roadbed side slope Method, present method solves during sea sand subgrade construction, due to rain drop erosion etc., the sea sand of roadbed side slope is easy by rain The problem that water washes away reduces the rehabilitation cost of roadbed, improves sea sand roadbed filling quality, accelerates sea sand subgrade construction speed.
In order to solve the above technical problems, the present invention includes such as the provisional protection method of highway sea sand roadbed side slope Lower step:
Step 1: collecting the cocoanut shell that area of bordering on the sea largely abounds with, cocoanut shell is ground into the coconut palm that fineness is 0.2mm with pulverizer Sub- silk;
Step 2: shredded coconut is woven into the thick coconut sheet fabric of 10m long, 2m wide, 0.03m, coconut sheet using braider Nylon rope is penetrated with width direction interval along its length in fabric;
Step 3: interim chute is arranged in interval on sea sand roadbed side slope, interim chute uses concreting, for arranging Except the rainwater on sea sand roadbed;
Step 4 is laid with coconut sheet fabric along roadbed length direction on the sea sand roadbed side slope between adjacent interim chute, In the upper edge embedment subgrade and pavement of coconut sheet fabric, lower edge are earthed at roadbed slope foot, on sea sand roadbed side slope Coconut sheet fabric is using fixed in U-shaped needle insertion sea sand;
Step 5: coconut sheet fabric is taken out when carrying out brush slope after the completion of sea sand roadbed filling, be used for next section of sea sand roadbed The provisional protection of side slope is constructed.
Further, penetrated in the coconut sheet fabric diameter of nylon rope be 0.5mm, spacing 0.2m.
Further, the interim torrent separation on the sea sand roadbed side slope is 10m.
Further, the depth of coconut sheet fabric upper edge embedment subgrade and pavement is 0.3m, lower edge is embedded to roadbed Depth at slope foot in soil is 0.5m.
Further, the U-shaped needle length is 150mm.
Provisional protection method due to the present invention for highway sea sand roadbed side slope uses above-mentioned technical proposal, i.e., our Method uses braider that shredded coconut is woven into coconut sheet fabric after cocoanut shell is ground into shredded coconut with pulverizer, and along length Direction and width direction penetrate nylon rope;Interval is arranged interim chute on sea sand roadbed side slope, adjacent interim chute it Between sea sand roadbed side slope on be laid with coconut flakes shape fabric, and upper edge embedment subgrade and pavement, lower edge is at roadbed slope foot In being earthed, the coconut sheet fabric in side slope is using fixed in U-shaped needle insertion sea sand;It is brushed after the completion of sea sand roadbed filling When slope, coconut sheet fabric is taken out, the provisional protection construction for next section of sea sand roadbed side slope.Present method solves sea sands During subgrade construction, due to rain drop erosion etc., the sea sand of roadbed side slope is easy the problem washed away by rainwater, reduces roadbed Rehabilitation cost, improve sea sand roadbed filling quality, accelerate sea sand subgrade construction speed.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
Fig. 1 is sea sand roadbed floor map in this method;
Fig. 2 is sea sand roadbed schematic cross-section in this method.
Specific embodiment
Embodiment is as depicted in figs. 1 and 2, and provisional protection method of the present invention for highway sea sand roadbed side slope includes Following steps:
Step 1: collecting the cocoanut shell that area of bordering on the sea largely abounds with, cocoanut shell is ground into the coconut palm that fineness is 0.2mm with pulverizer Sub- silk;
Step 2: shredded coconut is woven into the thick coconut sheet fabric 1 of 10m long, 2m wide, 0.03m, coconut sheet using braider Nylon rope 2 is penetrated with width direction interval along its length in fabric 1;
Step 3: interim chute 4 is arranged in interval in 3 side slope of sea sand roadbed, interim chute 4 uses concreting, uses Rainwater on exclusion sea sand roadbed 3;
Step 4 is laid with coconut sheet fabric along roadbed length direction in 3 side slope of sea sand roadbed between adjacent interim chute 4 1, in upper edge embedment 3 road surface of roadbed, the lower edge of coconut sheet fabric 1 are earthed at 3 slope foot of roadbed, 3 side of sea sand roadbed Coconut sheet fabric 1 on slope is using fixed in U-shaped needle 5 insertion sea sand;
Step 5: coconut sheet fabric 1 is taken out when sea sand roadbed 3 carries out brush slope after the completion of filling, be used for next section of sea sand road The provisional protection of base side slope is constructed.
Preferably, penetrated in the coconut sheet fabric 1 diameter of nylon rope 2 be 0.5mm, spacing 0.2m.
Preferably, 4 spacing of interim chute in 3 side slope of sea sand roadbed is 10m.
Preferably, the depth on 1 upper edge of the coconut sheet fabric embedment, 3 road surface of roadbed is 0.3m, lower edge embedment road Depth at 3 slope foot of base in soil is 0.5m.
Preferably, 5 length of U-shaped needle is 150mm.
This method is easily formed the problem in gully for sea sand roadbed by rain drop erosion, in conjunction with actual conditions analysis, research, just Ground materials are woven into coconut sheet fabric after being crushed using cocoanut shell and are layed on sea sand roadbed side slope, coconut sheet fabric Interim chute is arranged in side, and when rainwater is poured, rainwater flows out outside side slope along the vertical and horizontal shredded coconut of coconut sheet fabric, portion Rainwater is divided to flow into interim chute, in addition rainwater outflow roadbed side slope slope foot reduces so that rainwater be avoided directly to wash away sea sand The destruction of rainwater side slope ensure that the quality of roadbed filling, accelerate speed of application.
Cocoanut shell is low in cost in this method, and the coconut sheet fabric being woven into after crushed has certain toughness, makes It is long with the time, not cracky, and it is reusable, it will not aging, breakage by extraneous factors such as ultraviolet lights in use process;And The production of coconut sheet fabric is simple and easy, convenient and practical, has not only saved subgrade construction cost, but also has environmentally protective, saving certainly The outstanding advantages of right resource.
