Description

A kind of dykes and dams disappear unrestrained erosion control mask

Technical field

It the utility model is related to a kind of for dykes and dams, shore protection etc. in the engineering in the area such as river, lake, reservoir, coastal Disappear wave, the erosion control mask of engineering, particularly a kind of unrestrained erosion control mask that disappears being mixed to form by chemosetting stick and rubble.

Background technology

In the prior art, the dykes and dams in the area such as river, lake, reservoir, coastal, in bank-protection works, dykes and dams, shore protection etc. by Stormy waves, flow action, stormy waves is big or current are anxious, it is necessary to which the structure such as block stone, large-sized artificial block, concrete mix is prevented Shield, but be inadequate：

1st, block stone is loose material, and wind and wave resistance, flow action ability are small.

2nd, artificial block structure monolithic weight is big, and scene needs large scale equipment handling, installation etc., requires high to construction equipment； And bed course process is more, low construction efficiency.

3rd, for example the severe such as mold-bagged concrete, concrete slab is big, adaptive deformation is poor for concrete mix structure, it is difficult to resist compared with Big wave action, is not applied to when uneven settlement of foundation yet.

The content of the invention

Technical problem to be solved in the utility model is the defects of overcoming in the presence of above-mentioned prior art, there is provided a kind of Disappear the mask that wave, erosion control engineering use, can be significant while making it have good wave protective capacities, adaptive deformation ability Improve site operation efficiency.

The utility model employs following technical proposal and solves its technical problem：A kind of dykes and dams disappear unrestrained erosion control mask, its It is characterised by：The mask is covered in be stirred with aggregate by solidification stick in dykes and dams main body and formed, and its thickness is >=10cm ,≤ 5m, solidification stick are 3 with aggregate volume ratio:100, wherein 1~50cm of aggregate size.

It is of the present utility model to have the technical effect that strong good integrity, durability, ecological, environmental protective, construction technology are simple, using wide It is general.Available for the surfacecti proteon of the dykes and dams, bank-protection works in the area such as river, lake, reservoir, coastal, surface shield is applied also for Slope reparation, pavement structure etc..

Brief description of the drawings

Fig. 1 is the utility model structure diagram.

Each sequence number is expressed as in figure：

1-mask；2-blotter；3-dykes and dams main body, 4-thin sand.

Embodiment

With reference to embodiments and accompanying drawing the utility model will be further described.

Reference picture 1, mask described in the utility model are mixed by solidification stick and aggregate stirring to be covered in dykes and dams main body Conjunction forms.Calculated and determined according to hydrologic condition, to ensure self stability, its thickness is >=10cm ,≤5m.

Solidification stick, the proportioning of aggregate should meet the intensity of mixture used by the utility model, typically solidify stick It is 3 with aggregate volume ratio:100.

It is described in the utility model solidification stick use with solidification, attachment function and with aggregate bond after formation it is porous The polyurethane of structure, described aggregate are loose metaling, and wherein granite material is optimal.Wherein 1~50cm of aggregate size, most Good is 2.5~6.5cm.

In addition, being also equipped with one layer of blotter between mask described in the utility model and dykes and dams main body, the blotter is thick Degree is more than 20cm.

Further, one layer of thin sand can also be laid on mask described in the utility model as needed, the thin sand sand using amount Generally 2~4kg/m2, all it is defined by mask top layer by sand covering, the thin sand sand is natural sand, or synthetic sand, 0.002~2mm of its particle diameter.

The technical solution of the utility model is to be set using chemosetting stick polyurethane with crushed stone aggregate through normal agitation Standby mixing, topples over the surface for being cast in the engineerings such as dykes and dams, shore protection, Haihe River bed, and tool is formed after the solidification of polyurethane macadam-aggregate mix There is certain thickness mask.Its mechanism of action is to absorb wave, water using the loose structure formed between polyurethane and rubble The energy of stream effect, reach good disappear wave, the effect of erosion control.

It is of the present utility model to implement by material is mixed with transporting, pavement structure pours realization.

1st, the mixing of polyurethane macadam-aggregate mix and transportation technology

Before being mixed with polyurethane, crushed stone aggregate need to keep its surface cleaning, drying through rinsing and dry, and not Containing excessive impurity.According to field operation condition, can a point two methods implement：If field condition allows, rubble is carried out at the scene Cleaning, after drying, after mixing, stirring in agitator with polyurethane, repave and be set in dykes and dams；If field condition is limited, Chemosetting stick can be divided into stick and curing agent, the mixing of stick and rubble is first carried out in backup site, formed to have and glued Property but not solidification first batch mixing, the scene of being transported to adds curing agent and uses agitator mixing after-pouring.

The agitator uses open tubbiness, requires that itself is rotatable or inner bag is rotatable, recommends concrete mixer truck. Crushed stone aggregate is put into agitator, then chemosetting stick polyurethane is continuously injected into by pipeline；Or the mode in agitator Polyurethane, then rubble is at the uniform velocity transmitted using conveyer belt and entered in agitator.

Mixing time at least needs to make building stones fully be wrapped up by polyurethane, but to avoid polyurethane macadam-aggregate mix from solidifying, when Between can not be long, be usually no more than presetting period of curing agent after mixing curing agent.

The transport of first batch mixing can use all kinds of transport vehicle transports, such as dump truck.

2nd, polyurethane macadam-aggregate mix pour, laying process

The effect that is connected for ease of compound with levee body structure, compound pours, lay before laying depth be not less than 20cm Blotter.Compound is clawed from transport vehicle using Vehicle tipping or artificial scoop again, constant speed is kept, is quantitative by compound Domatic upper, leveling is poured over, without vibrating or tamping, treats its automatic solidification.

To strengthen the bonding strength of contact point between metaling, improving the anti-ultraviolet ability of structure, rough to build by adding More preferable ecological effect etc., before mixture laying is completed not yet to solidify, then on polyurethane macadam-aggregate mix pavement structure surface Lay a thin sand.The thin sand sand using amount is generally 2~4kg/m2, is specifically all defined by top layer by sand covering.Sand can To use natural sand or synthetic sand（Slag, chip etc.）, recommend to use quartz sand, 0.002~2mm of particle diameter, divide at random Cloth can, but in, thick, fine sand is preferred.
