The utility model relates to a prefabricated dislocation of picture peg type is crossed ecological bank protection of well belongs to the hydraulic engineering field, is applicable to the construction of river course bank protection, and it is limited to be particularly useful for the ground scope, ecological, view nature and the high river course bank protection construction of hydrophilicity requirement.

Background

The traditional revetment is a reinforced concrete hard revetment and is widely applied to various projects, and a retaining wall body and a retaining wall bottom plate form a closed barrier, so that water and soil exchange at two sides of the wall body is hindered, soil on which aquatic plants and animals live is closed, and the original ecological chain of a river channel and a bank is blocked. In addition, water landscape and water ecology are attached to rivers or lakes, banks of waterfront water become important cultural resorts for tourism, leisure and close to nature, and urban residents urgently want to improve ecological property, hydrophilicity and landscape property. In addition, the land in urban living areas is tense and precious, and the bank protection structure is required to occupy as little land as possible. Therefore, the bank protection structure can simultaneously meet the requirements of hydrophilicity, ecological environmental protection and environment beautification on the basis of ensuring the safety and reliability of the structure, meets the flood-carrying safety requirement, has a better hydrophilic ecological landscape function, and occupies less land, which is a problem to be solved urgently.

Aiming at the problems, the development of the inserting plate type prefabricated dislocation water passing well ecological revetment which is good in ecological property, landscape property and hydrophilicity, high in construction efficiency, convenient and fast to operate, stable in structure, small in occupied area, high in industrialization degree and small in construction pollution is particularly key. The utility model discloses it just develops under such background and forms, must gain obvious economic benefits and social in being applied to actual river course revetment construction.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a prefabricated dislocation of picture peg type crosses the ecological bank protection of well to the unable exchange of traditional river course bank protection soil and water, ecological chain blocked, ecological nature, hydrophilicity and the poor scheduling problem of view nature, this ecological bank protection ecological nature, view nature and hydrophilicity are good, the efficiency of construction is high and simple operation, the structure is firm, area is little, the high just construction pollution of industrialization degree is little.

In order to realize the technical purpose, the utility model discloses a following technical scheme:

the inserting plate type prefabricated dislocation water passing well ecological revetment comprises a prefabricated dislocation water passing well, a prefabricated foundation, a prefabricated L-shaped inserting plate, a cast-in-place pile and backfill soil; prefabricating front and rear staggered openings of the staggered water passing well; a plurality of prefabricated staggered water passing wells are arranged on the upper part of the prefabricated foundation; a prefabricated L-shaped inserting plate is arranged between the prefabricated staggered water passing wells; step-shaped binge gabion is arranged at the water side of the prefabricated L-shaped inserting plate; water storage stones are arranged in the well of the prefabricated staggered water passing well and behind the well; the water storage rubbles are sequentially upwards provided with water filtering crushed stones A, a sand filtering layer and planting soil A in the well, and the water filtering crushed stones B and backfilling soil are sequentially upwards arranged behind the well.

Preferably, the cast-in-place pile is arranged in a riverbed, and a foundation cushion layer is arranged at the upper part of the cast-in-place pile; the prefabricated foundation is arranged on the upper part of the foundation pad layer.

Preferably, the waterside of the prefabricated foundation is provided with the rock block.

Preferably, the upper part of the backfill soil is sequentially provided with an inverted filter layer, plant growing concrete and planting soil B.

Preferably, the water storage rubbles, the water-filtered gravel B and the bottom and the waterside of the backfill soil are provided with a reverse filter layer.

Adopt the technical scheme provided by the utility model, compare with prior art, have following beneficial effect:

(1) good ecological, landscape and hydrophilic properties. The front and back staggered openings of the prefabricated staggered water passing well break the closed interface of the traditional pile plate wall, form a channel for water quality exchange between a river and a bank, and the staggered openings prolong the path of water quality circulation, so that the water quality can be fully purified and stored in the multi-stage filling materials outside the well. Meanwhile, the upper part of the prefabricated L-shaped plugboard is provided with the hydrophilic board, and aquatic plants are planted in the well mouths at two sides of the hydrophilic board, so that a hydrophilic space with good appearance is created above the normal water level. In addition, prefabricated L type picture peg is close to water side construction step form binge gabion, provides more living space for aquatic animal and aquatic plant, when clearing up rivers impact force, has also richened the view effect of revetment.

(2) High and the simple operation of efficiency of construction. The one-time accurate taking in place of prefabricated dislocation water passing well has been realized through basic stopper, and the well shaft is transferred the back of taking in place, need not the secondary adjustment mounted position, and only need can realize outside the well that prefabricated well is fixed with the bolt joint of prefabricated basis, and the workman need not to get into the interior operation of well, and the security is higher. Simultaneously, through inserting between the prefabricated well and establishing prefabricated L type picture peg, can install fender native board and hydrophilic board in step, compare traditional sectional type and keep off native board, improved the efficiency of construction greatly, and need not to set up hydrophilic platform in addition.

(3) The structure is stable. The post-cast concrete is poured in the foundation groove, the prefabricated well, the inserting plate and the foundation are connected into a whole to bear force, the structure is integrally more stable, the stress effect is better, and the service life and the safety performance of the revetment structure are prolonged. Meanwhile, the inside and the back of the prefabricated well are filled with the rubbles, so that the soil pressure behind the well is reduced, and the adverse effects of residual water pressure and permeability on a bank slope during water level reduction can be reduced through the large pores of the rubbles. In addition, the inverted filter layer is laid at the bottom of the multistage filler on the back of the prefabricated well and on the side close to water, so that the soil loss of the bank can be effectively prevented, and a good soil retaining effect is achieved.

(4) The occupied area is small. The width of the prefabricated dislocation water passing well is narrow, only a small water passing section is occupied, the navigation space of a river channel is not influenced, the bank protection construction requirement of a river in a narrow city can be met, and the application range is wide.

(5) High industrialization degree and little construction pollution. The prefabricated staggered water passing well, the prefabricated L-shaped inserting plate and the prefabricated foundation are standardized prefabricated components, the industrialization degree of the components is high, the quality is guaranteed, the wet operation amount of a construction site is greatly reduced, and the construction pollution is small.
