Description
technical field
The utility model relates to the channel revetment structure of a kind of hydraulic engineering and municipal engineering, especially relates to a kind of city river pile-column framework bank protection structure.
Background technology
In city river, because surrounding building is intensive, the land red-line of river course planning or transformation is limited in scope, generally adopt the single formula of rising steeply bank protection structure or top be slope greening band, middle for water balcony, bottom be the compound section bank protection structure of formula shore protection of rising steeply.City river need meet the basic functions such as retaining, water drainage, view, and bank protection structure is conventionally fairly simple, is generally following several structural shape: (1) piece stone barricade; (2) concrete guard wall; (3) concrete " U " shape groove.
Along with socioeconomic development, traditional river regulation theory just progressively changes, and " water quality is limpid, ecological beauty, bank road unimpeded " become the basic demand of city river.
Old town urban architecture is generally near River Construction, supporting available space in river course is smaller, traditional urban river bank protection structure excavation takes up an area large, inconvenience construction when narrow in periphery place, adopts after the space enclosing structures such as steel sheet pile, diaphragm wall, and space enclosing structure has just been born the function of construction provisional protection therein, after channel revetment is built up, be generally to remove or waste treatment, do not double as channel revetment structure, comprehensive utilization degree is not high.
Fix, do not reduce riverbank land used on riverbank and river course overall width and ensure under the unimpeded prerequisite in bank road, tradition channel revetment is except deepening the river course, cannot expand river course flow section, and the river course of narrow dark formula has not only strengthened the enforcement difficulty of shore protection, also deepened the water body of city river, unfavorable safety, hydrophily is poorer.
The underground river structure of box culvert or slab culvert formula is conducive to the stable and top the coast is clear of shore protection, but river course seals completely, can not meet hydrophily requirement, is not suitable for extensive use.
Bottom is that the double-deck river course structure that box culvert, top are open channel can solve few occupation of land simultaneously, shore protection is stablized and hydrophily problem, but be only applicable to abrupt slope, deep trouth section, restricted application, and, the base plate ecological property of hard type is poor completely, is also unfavorable for the purification of water quality.
Utility model content
The purpose of this utility model is to provide a kind of city river pile-column framework bank protection structure, in safeguarding that river course surrounding building is stable, widens river course flow section, improves water quality and ecological effect, improves hydrophily.
The purpose of this utility model is achieved by the following technical solution: a kind of city river pile-column framework bank protection structure, it is mainly by concrete pile body, concrete diaphragm, concrete bottom beam, concrete column and concrete beam plate composition, it is characterized in that: described concrete pile body is arranged at the bank slope side in river course, concrete bottom beam is arranged in river course, described concrete column is cast in by column joint bar on the basis of concrete bottom beam, concrete diaphragm is cast between concrete pile body by dividing plate joint bar, concrete beam plate is cast in the top of concrete pile body and concrete column.
The riverbed face of described concrete column both sides is equipped with earth blanket, is equipped with cobble river bottom protection layer above earth blanket.
Described concrete beam plate surface is provided with side walk slab, and river course lateral edges is provided with guard bar structure.
A construction method for city river pile-column framework bank protection structure, comprises the following steps:
(a) at riverbank construction concrete pile body, described concrete pile body adopts concrete drilling bored concrete pile or hand excavated pile, and the pile body degree of depth is according to calculative determination, and top extends on ground;
(b) cut the open structure at concrete pile body top, excavate the soil body of concrete pile body river course side, the soil body between removing concrete pile body is to the position of center line of concrete pile body, construction dividing plate joint bar, the soil body after concreting dividing plate between concrete pile body is for the wall between a gear concrete pile body, the top cast-in-situ concrete leveling layer of concrete pile body;
(c) in river course foundation ditch, Parallel to the flow direction is constructed after concrete cushion, build the concrete bottom beam for supporting concrete column, reserved column joint bar on concrete bottom beam, concreting column, riverbed, inner side surface construction earth blanket, re-lays cobble river bottom protection layer on it;
(d) at concrete pile body top and concrete column top construction concrete beam plate, concrete beam plate surface adopts side walk slab's facing to form trip pavement, and guard bar structure is established at edge, and concrete beam plate top also can be laid planting soil and be formed greenbelt;
(e) form frame construction by concrete pile body, concrete diaphragm, concrete column, concrete beam plate, after completion, the earth blanket at position, the outer riverbed of implementation framework, re-lays cobble river bottom protection layer on it.
The beneficial effects of the utility model are:
(1) the utility model not only has the gear soil of traditional cities channel revetment, the function of retaining, compared with existing open channel revetment technology, in urban land anxiety, the difficulty of removing, when surrounding building is intensive, the utility model directly utilizes space enclosing structure to make shore protection, and comprehensive utilization degree is high;
(2) tower structure is not in reducing riverbank land used, keeping bank road unimpeded, and neither deepening of riverbed, can expand again the flow section in river course, increases hydrophily;
(3) in framework, the riverbed face of expansion is implemented earth blanket and cobble river bottom protection layer, is conducive to bryophyte growth, reaches the effect of improving water quality and riverside landscape.
(4) the utility model provides a kind of construction method, concrete pile body adopts hand excavated pile, in the time not having condition to arrange that builder's road, the narrow construction machinery in construction plant cannot be arranged or surrounding building has higher vibration isolation requirement, still can implement channel revetment Ji An road.
