The arrangement of the siltation dams is generally that a series of step dams are respectively built on the furrows, the branch ditches and the main ditches according to the area of a channel watershed, and the building of the siltation dams has very important significance for lifting a channel erosion reference surface, preventing and controlling water and soil loss, retaining flood, blocking mud, silting land, reducing river sediment and the like, and is an important measure for comprehensive treatment of small watersheds.

Example 1:

a maintenance-free integrated check dam comprising:

the homogeneous earth dam comprises a homogeneous earth dam body 1 and a protective layer arranged on the homogeneous earth dam body 1; the protective layer comprises an upstream slope protection layer 2 arranged on the upstream slope surface of the homogeneous earth dam body 1, a downstream slope protection layer 3 arranged on the downstream slope surface of the homogeneous earth dam body 1 and a mixed material layer 4 arranged on the top of the homogeneous earth dam body 1, wherein the mixed material layer 4 is integrally connected with the upstream slope protection layer 2 and the downstream slope protection layer 3;

multiple layers of drainage blind pipes 5 are embedded in the homogeneous earth dam body 1 at intervals (if a plurality of layers of drainage blind pipes are horizontally arranged along the vertical direction, each layer is provided with a plurality of drainage blind pipes), and pipe orifices of the drainage blind pipes 5 penetrate through and extend out of a downstream slope protection layer 3 to the external environment (the external environment of a silt dam).

Preferably, the thickness of the protective layer of the upstream dam slope is 1.0 m-1.5 m, and the thickness of the protective layer of the downstream dam slope is 2.0 m-3.0 m; the downstream dam slope is subjected to continuous scouring of water flow, so that the thickness of the downstream protective layer is greater than that of the upstream protective layer;

preferably, the distance between two adjacent layers of the drainage blind pipes 5 is 3m, the distance between two adjacent drainage blind pipes 5 in the same layer is 3 m-5 m, and the uniformly arranged drainage blind pipes 5 can timely discharge the seepage water in the dam body out of the dam body so as to increase the stability of the dam body.

Preferably, the same mixture is adopted by the upstream slope protection layer 2, the downstream slope protection layer 3 and the mixed material layer 4; the same mixture adopted by the upstream slope protection layer 2, the downstream slope protection layer 3 and the mixed material layer 4 can effectively ensure that the upstream slope protection layer 2, the downstream slope protection layer 3 and the mixed material layer 4 are connected into a whole, and the construction process can be effectively simplified.

Preferably, the mixture is prepared by uniformly mixing 70-90% of damming soil and 10-30% of argillaceous fine sand consolidation agent by weight; the argillaceous fine sand consolidation agent is prepared by calcining argillaceous fine sand powder 12, mineral powder and cement according to the weight percentage of 70-80%, 5-10% and 10-25%. The strength of the dam slope is obviously improved by adding the argillaceous powder fine sand consolidation agent into the dam building soil, and the strength is equivalent to C10-C15 concrete through tests, so that the anti-scouring capability and the comprehensive durability of the dam slope are improved, and the aim of no management and protection is fulfilled. The argillaceous fine sand consolidation agent contains mineral powder with a content of less than 10%, cement with a content of less than 25%, and more than 70% (weight percentage) of the argillaceous fine sand consolidation agent is calcined argillaceous fine sand fine powder 12.

Preferably, the mixture is prepared by uniformly mixing 60-75% of damming soil, 20-25% of fly ash, 13-18% of slag, 5-8% of red mud and desulfurized gypsum according to the weight ratio of 8-15: 5-8%, and the mixture has good compressive strength and can effectively improve the strength of upstream and downstream dam slopes.

Preferably, the mixture is prepared by uniformly mixing 68-75% of damming soil, 33-35% of cementing material, 15-18% of modified cellulose and 0.5-1.2% of bitter soil powder in a weight ratio; wherein, the cementing material adopts cement and iron slag according to the proportion of 93-98%: 2 to 7% by weight; the modified cellulose adopts high-modulus polyethylene fiber which is mineralized in calcium phosphate mineralized liquid. In the actual mixing, a salt solution of magnesium chloride is adopted as a mixing agent for mixing; the mixture is coagulated into blocks after being mixed, and the high-strength concrete has high strength.

The working principle and the beneficial effects of the technical scheme are as follows: compared with the existing silt dam which is made of local materials and adopts silt soil to build the silt dam, the silt dam has lower flood control standard, increases the anti-scouring capability of upstream and downstream dam slopes, and improves the flood control standard; and the mixed material layer 4 can ensure that the dam body can overflow, and the dam cannot break when the over-standard flood is exceeded, so that a water release structure can be cancelled, and the engineering investment of the dam body is greatly saved.

Example 2

On the basis of the example 1, the method comprises the following steps of,

as shown in fig. 2, the process system structure of the mixing process includes: the system comprises an aggregate bin 6, a metering system 7, an aggregate conveying system 8 (a herringbone belt conveyor), a stair and a railing 9, a main machine building 10, an aggregate transition bin 11, a cement, water and additive system, a stirring system 13, a spiral conveyor 14 and a vertical powder tank 15;

a mixing process of the mixture adopted by the upstream slope protection layer 2, the downstream slope protection layer 3 and the mixture layer 4 of the pipe-free and protection integrated silt dam comprises the following steps:

the method comprises the following steps: storing three materials of calcined argillaceous powder, fine sand and fine powder 12, mineral powder and cement in 3 vertical powder tanks 15 near an automatic metering system 7 respectively; the damming soil is stocked near the automatic metering system 7;

step two: respectively starting a powder tank screw conveyor 14 and an automatic metering system 7, respectively metering the weight of calcined argillaceous powder fine sand fine powder 12, mineral powder and cement according to the weight ratio of 70-80%, 5-10% and 10-25%, and feeding the three materials into a mixed material stirring system 13;

step three: the stirring system 13 uniformly mixes the calcined argillaceous powder fine sand powder 12, the mineral powder and the cement according to a specified time to form an argillaceous powder fine sand consolidation agent, and then the argillaceous powder fine sand consolidation agent is stacked near the metering system 7;

step four: respectively loading the mixed argillaceous fine sand consolidation agent and damming soil into a bin of an automatic metering system 7 by adopting a loader;

step five: starting an automatic metering system 7, metering the weight of the argillaceous powder fine sand consolidation agent and the dam building soil material according to the weight ratio of 10-30% and 70-90%, and feeding the two materials into a mixed material stirring system 13;

step six: the stirring system 13 uniformly mixes the argillaceous fine sand consolidation agent and the dam-building soil according to a specified time to form a mixture of the upstream and downstream slope protection layers 3 and the mixed material layer 4, and then the mixture is transported to the dam by a dump truck for unloading, paving, adding water and rolling.

Various mixed materials composed of different materials and mixing proportions have the material with the mixing amount less than 10 percent, the minimum weight ratio is only 0.5-1.2 percent, and the mixed materials are difficult to be uniformly mixed by the traditional mixed material construction process, so that the expected performance index of the mixed materials cannot be reached.

The contents of the mineral powder and the cement are much lower than the cement content, and the purpose of uniformly mixing various materials is difficult to achieve by adopting the traditional horizontal interbedded paving vertical mining method, the dam surface stacking blending method and the funnel belt conveyor blending method.

The traditional blending process of the admixture comprises the following steps:

the soil material in the earth-rock dam is blended with a certain admixture to be processed into the admixture, and the following problems can be respectively or comprehensively solved: the compressibility of the soil is reduced, and the anti-seepage body is prevented from cracking; the water content of the soil material is reduced, and the construction control water content of the anti-seepage body is improved; the construction characteristics of the seepage-proofing filling material are improved, and the filling speed is increased; the anti-seepage performance of the anti-seepage body is improved; saving soil and reducing occupied area, etc.

The construction process of the common admixture for the earth-rock dam comprises the following three steps:

1) the materials are spread horizontally and mutually according to the proportion, and the vertical face is mined and blended.

2) Stacking various materials alternately on the dam surface, and pushing and blending the materials by a bulldozer.

3) Various materials are measured by a funnel and then are discharged onto the same belt conveyor for preliminary blending; blending method of re-blending after transporting to stockpile.
