Description
Technical Field
The utility model belongs to the technical field of river lake shore protection technique and specifically relates to an existing river lake shore protection rebuilds structure.
Background
At present, a large number of existing river and lake revetments with low design standards exist, and gradually lose the protection capability after being washed and eroded by river water and lake water for a long time; in addition, for many new projects, ground elevation needs to be raised, so that the existing revetment needs to be heightened and reinforced. Heightening and reinforcing inevitably lead to heavier original revetment, and particularly gravity type revetment has greatly increased thickness and influences the attractiveness.
With the advance of urbanization process, the traditional river and lake bank protection structure can not meet the requirements of people on ecological landscape, and the requirements of ecological landscape need to be considered for river and lake bank protection reconstruction.
Disclosure of Invention
The utility model provides an existing river lake shore protection rebuilds structure can take into account ecological environmental protection demand, and is comparatively pleasing to the eye moreover, can regard as the sightseeing pavement.
The utility model adopts the following technical proposal.
A reconstruction structure of an existing river and lake shore protection is used for reconstructing an existing gravity type shore protection of rivers and lakes, and comprises a plurality of precast concrete sheet piles arranged on the side of the back face of the existing gravity type shore protection; a filling structure for separation is arranged between the precast concrete sheet pile and the gravity type revetment; the top of the precast concrete sheet pile is provided with a cornice crown beam; the overhanging crown beams of adjacent precast concrete sheet piles are combined into a plank road.
The back of the gravity type revetment is a revetment surface facing a river bank; the distance between the precast concrete sheet piles and the gravity type revetment is maintained within a preset threshold range.
The pile body of the precast concrete sheet pile is provided with a plurality of hole structures from bottom to top; a coir wire mesh is fixed in the hole structure; the spacing range between the hole structures is 500 mm-1000 mm.
The pile head of the precast concrete sheet pile is sleeved with a steel sleeve head structure; and a stud is arranged on the surface where the steel sleeve head structure is matched with the pile head.
The cornice crown beam is a concrete structure cast in situ at the top of the precast concrete sheet pile.
The filling structure is formed by stacking and filling bagged broken stones or bagged soil.
Compared with the prior art, the utility model discloses following beneficial effect has: compared with the method of directly heightening and widening the original revetment, the method for rebuilding the river and lake revetment has the advantages of ecology, attractive appearance and the like.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to specific embodiments and related drawings.

Detailed Description
As shown in the figure, the reconstruction structure of the existing river and lake revetment is used for reconstructing an existing gravity type revetment 2 of a river and lake 1, and comprises a plurality of precast concrete sheet piles 4 arranged at the side of the back of the existing gravity type revetment; a filling structure 3 for separation is arranged between the precast concrete sheet pile and the gravity type revetment; the top of the precast concrete sheet pile is provided with a cornice crown beam 6; the overhanging crown beams of adjacent precast concrete sheet piles are combined into a plank road.
The back surface of the gravity type revetment is a revetment surface facing a river bank; the distance between the precast concrete sheet piles and the gravity type revetment is maintained within a preset threshold range.
A plurality of hole structures 8 are arranged on the pile body of the precast concrete sheet pile from bottom to top; a palm wire mesh is fixed in the hole structure; the spacing range between the hole structures is 500 mm-1000 mm.
A steel sleeve head structure 5 is sleeved at the pile head of the precast concrete sheet pile; and a stud 9 is arranged on the surface where the steel sleeve head structure is matched with the pile head.
The cornice crown beam is a concrete structure cast in situ at the top of the precast concrete sheet pile.
The filling structure is formed by stacking and filling bagged broken stones or bagged soil.
Example (b):
the method comprises the steps of arranging a plurality of precast concrete sheet piles at the side of the back of the existing gravity type revetment at preset intervals, then forming a cornice crown beam in a cast-in-place mode at the pile top, enabling the cornice crown beams to be connected and combined into a gallery, and enabling the gallery to extend to the ground 7 to allow shoreside tourists to visit the gallery.
