Description

Self-locking type revetment stone prepared from yellow river silt and using method thereof
Technical Field
The invention belongs to the technical field of hydraulic engineering, and relates to a self-locking bank protection stone prepared from yellow river silt and a using method thereof.
Background
In order to maintain the stability of the river shoreline, prevent disasters such as side erosion of the river, bank collapse caused by local scouring of the river channel and the like, or to make the main flow line deviate from a scoured section, necessary bank protection engineering measures need to be taken. The engineering revetment is a rigid engineering revetment formed by reinforcing an original natural bank slope, meets engineering requirements of flood control, water delivery, shipping and the like, and is safer and more effective compared with cage stones and riprap revetment. The common building materials such as concrete, masonry and the like have good impact resistance, erosion resistance and durability, and can reduce the roughness, improve the water delivery efficiency and reduce the permeation loss for the artificial canal for water delivery. But resources along the yellow river are characterized in that silt is deposited and becomes sick, stone is barren and is transported outside, and obviously, the traditional concrete and stone revetment are uneconomical; for flood dike-breaking exit rescue projects, the water-soluble fertilizer can not be nearly thirsty even if being hydrolyzed far away.
When flood dike breach doors are used for emergency rescue, the common stone cage and stone throwing measures are low in efficiency, large in construction difficulty and high in risk. Even if the advanced throwing technology is adopted, such as a triangular conical steel frame (patent No. 201620690588.2) for blocking dike breach, the ideal effect is difficult to achieve due to the limited manual throwing power and the overlarge flood flow rate at the breach; other methods such as the soft block method of river levee breach (patent number 99115001.5) require manual jumping into the torrent of flood to complete the piling construction; the 'anti-break dike and dam-break plugging boat' (patent number 201521008895.x) needs manual operation of large ships and vehicles to sink and plug the bottom, and the cost is very high.
Particularly, with the aggravation of global climate change, in recent years, the number of flood fields at the downstream of the yellow river, the long process, the large magnitude of the magnitude are frequently refreshed, and the defense task is difficult and heavy, so that a bank protection material which greatly utilizes local silt resources, a corresponding bank protection engineering structure and a set of efficient, rapid, safe and feasible dam breach rapid rescue method are urgently needed to be developed, the construction efficiency is improved to the maximum extent, the construction risk and the cost are reduced, and the safety of the yellow river dam is ensured.
Disclosure of Invention
In order to solve the problems, the invention provides a self-locking type bank protection stone prepared from yellow river silt and a using method thereof.
The technical scheme of the invention is as follows:
a self-locking revetment stone comprises a revetment stone main body 11 and a self-locking convex hole 12, and is in a frog-type shape as shown in figure 1. The main bodies 11 are arranged into layers along the construction axis, and the upper layer and the lower layer are spliced by the self-locking convex holes 12 to realize self-locking, so that an integral self-locking revetment stone structure is formed.
The main body 11 is I-shaped, and the thickness of the main body is 50 cm; it comprises a pair of forelimbs 13 and a pair of hindlimbs 14 between which is a joint stem 17. The total length of each of the front limb and the rear limb is 180cm, the width of each of the front limb and the rear limb is 30cm, the middle part of each of the front limb and the rear limb is 60cm, the front projection 15 and the rear recess 16 are respectively arranged, the length of each of the front limb and the rear limb is 60cm, and the depth of the projection and the recess is 10cm, so that the front limb and the rear limb are more tightly meshed with each other when the main bodies in the revetment stone layer batch are arranged.
The self-locking convex hole 12 is positioned on a connecting trunk 17 between the front limb and the rear limb of the main body and comprises a tenon 12-1 part and a mortise 12-2 part. The tenon 12-1 is a cubic prism or a cylinder with the side length of 30cm and the height of 50cm or the side length of 30cm, and is vertical to the connecting trunk 17; the mortise 12-2 is a rectangular square hole with a side length of 30cm or a round hole with a diameter of 30cm, which vertically penetrates through the connecting trunk 17. The convex hole structure is convenient for the butt-hole insertion between the upper layer and the lower layer of the revetment stone, and the positioning and self-locking are realized, so that the firm and stable revetment stone structure with extremely strong integrity is formed. The mortise 12-2 at the lowest layer can be combined with the upward beard rib 33 reserved on the foundation mat layer; the tenon 12-1 at the uppermost layer can be used as a guardrail of bank protection engineering.
The self-locking type bank protection stone can change the sizes of all parts according to engineering requirements on the premise of keeping the appearance and the structure unchanged; when the dead weight reaches more than 20 tons, normal reinforcement needs to be considered.
The self-locking type revetment stone can be prepared from yellow river silt, and the proportion of ingredients is cement: water: coarse aggregate of yellow river silt: fine aggregate of yellow river silt: the additive is 1: 0.35-0.55: 3.0-5.0: 1.5-2.0: 0.01-0.02, and the components are mixed and stirred in proportion, poured and molded, and cured to be at a proper age.
The cement is general portland cement or road cement.
The fine aggregate of the yellow river silt is coarse particles (the particle size is more than or equal to 100um) in the silt.
The yellow river sediment coarse aggregate is artificial coarse aggregate obtained by carrying out double-roller extrusion granulation on fine particles (the particle size is less than 100 mu m) in sediment, and the particle size is controlled to be 2.5-40 mm.
The additive is a polycarboxylic acid water reducing agent with a glue reducing function.
And adopting a forming and curing process, such as mechanical stirring and vibration forming of conventional concrete, and standard curing, natural curing or steam curing.
The invention adopts the yellow river silt as the main raw material to prepare the revetment stone, replaces the traditional natural stone and broken stone aggregate, reduces the consumption of the natural aggregate and obviously reduces the cost. The problem of stone aggregate shortage in plain areas is solved, a new direction is provided for realizing large-scale resource utilization of yellow river silt, and an effective solution is provided for the problem of yellow river silt sedimentation. The self-locking type bank protection stone is used for bank protection engineering, has high structural strength, good stability, long service life and convenient construction, and has obvious effects of protecting the bank and keeping water and soil. The self-locking type bank protection stone is used for rescuing at dike breach doors, and has the advantages of good plugging effect, high construction efficiency and low construction risk.
