Description
Technical field
The present invention relates to hydraulic engineering technical field, more particularly, to a kind of unconventional storage capacity list Longkou protection structure and its
Closure method.
Background technology
In recent years, with the sustained and rapid development of urban construction, land resource shortage problem getting worse will be sent out to ocean
Exhibition space has become a kind of common recognition in lot of domestic and foreign city, and shore reclamation utilizes the important way for becoming and opening up new land resource
Diameter.Large-scale reclamation engineering has been carried out in many coastal cities, and spends a huge sum of money that surrounding area is gone to buy silt epeirogenetic.This
It is wherein again more with tidal estuary area and coastal area corral engineering, into Lu Zuoyong from original simple farming land, build
Land used is replaced, and is converted to the environmental protection aspect demand such as consumption urban architecture dregs, cruiseway dredging markets.Meanwhile monomer quantities
Also it drastically rises.
It meets an urgent need corral engineering for the consumption engineering dregs that some durations are tight, storage capacity is big, the lattice ridge is built without the slack time,
Area is enclosed in segmentation, sets more Longkous.Therefore, Ge Geng is not built in enclosing, single Longkou is set, therefore, big storage capacity only sets a Longkou, dragon
Mouth ultra-wide, the research of Longkou protection structure has a very big significance, to facilitate subsequent construction.
The information for being disclosed in the background technology part is merely intended to deepen understanding of the general background technology to the present invention, and
It is not construed as recognizing or implies that the information forms the prior art known to those skilled in the art in any form.
Invention content
The purpose of the present invention is to provide a kind of unconventional storage capacity list Longkou protection structure and its closure methods, can prescribe a time limit
Guarantee both quality and quantity closure in place, complete node tasks, for consumption engineering dregs carry out element task, while evaded because can not join the two sections of a bridge, etc
Work(and need to additionally expend people, material, machine loss.
To achieve the above object, the present invention provides following technical scheme：
In a first aspect, the present invention provides a kind of unconventional storage capacity list Longkou protection structure, including：It is river bottom protection layer, first elongated
Pipe bag layer, reinforcing layer and the second elongated pipe bag layer；
The river bottom protection layer is located at below the described first elongated pipe bag layer and the second elongated pipe bag layer, is protected for beach face
Bottom；
The reinforcing layer is between the described first elongated pipe bag layer and the second elongated pipe bag layer.
Further, the river bottom protection layer includes sand ribbed soft mattress and concrete interlocking segment is arranged.
Further, the described first elongated pipe bag layer and the second elongated pipe bag layer are layed in the river bottom protection layer top so that institute
It states unconventional storage capacity list Longkou protection structure and reaches 1.5m-2.0m absolute altitudes.
Further, the reinforcing layer includes civil grille.
Further, the civil grille includes two kinds of longitudinal grid items and two kinds of oblique grille strips；Two kinds of longitudinal directions
Grid round is placed, and the civil grille is compiled into two kinds of oblique grille strip knots.
Further, in two kinds of longitudinal grid items, groove is provided in second of longitudinal grid item, and place
Position is less than the first described longitudinal grid item.
Further, in two kinds of longitudinal grid items, the first described longitudinal grid surface is arc-shaped.
Further, two kinds of oblique grille strips are provided with groove, are divided into left oblique grille strip and right oblique grille strip.
Further, the reinforcing layer further includes geotextiles, and the geotextiles are equipped with the civil grille.
Further, the geotextiles are equipped with anti-skid bulge away from the civil grille one side.
Second aspect, the present invention also provides a kind of closure method of unconventional storage capacity list Longkou protection structure, including：
Sand ribbed soft mattress and concrete interlocking segment row are laid with as river bottom protection layer；
River bottom protection layer top sets two layers of elongated pipe bag to form the first elongated pipe bag layer and the second elongated pipe bag to 1.6m absolute altitudes
Layer is laid with one layer of reinforcing layer between the first elongated pipe bag layer and the second elongated pipe bag layer.
Unconventional storage capacity list Longkou protection structure provided by the invention and its closure method have the advantages that：
First aspect present invention provides a kind of unconventional storage capacity list Longkou protection structure, including：River bottom protection layer, the first elongated pipe
Bag layer, reinforcing layer and the second elongated pipe bag layer；River bottom protection layer is located at below the first elongated pipe bag layer and the second elongated pipe bag layer, is used for
Beach face river bottom protection；Reinforcing layer is between the first elongated pipe bag layer and the second elongated pipe bag layer.
By taking the emergency work promptly to start to dissolve the big scale of construction engineering dregs of urban construction generation as an example, the engineering
2.2 ten thousand mu of corral area to ensure within 48 effective working days, is completed Longkou closure node tasks, by checking repeatedly, is not had
There is the slack time to build the lattice ridge, segmentation encloses area, sets more Longkous.It is final to determine, enclose in do not build Ge Geng, single Longkou, protection are set
Phase Longkou width 600m.So big storage capacity only sets a Longkou, so wide Longkou, also, this engineering again and emergent work
Journey attribute, dregs are marched into the arena very urgent, and no time allows to attempt second to join the two sections of a bridge, etc, it is necessary to which primary closure is in place.The waters system
Tidal reaches, are influenced more by natural cause and construction organization factor, and embankment quality requirement is higher, and advantage is that sand source is relatively filled
Foot.Based on above-mentioned actual conditions, join the two sections of a bridge, etc to Longkou construction and Longkou protection, Longkou scale and building site present situation, hydrologic condition, Longkou
Monitoring after the meteorological condition and tide of phase, the selection of Longkou closure phase, closure work amount, closing construction flow and closure is seen
The technologies such as survey and protection are studied and pass through numerical check.The unconventional storage capacity list Longkou protection that first aspect present invention provides
Structure uses river bottom protection layer river bottom protection, and it is the first elongated pipe bag layer and the second elongated pipe bag that river bottom protection layer top, which sets two layers of elongated pipe bag,
Layer is laid with one layer of reinforcing layer between the first elongated pipe bag layer and the second elongated pipe bag layer, complete the Longkou protection to the engineering,
To facilitate development follow-up work.
The protection structural defence Longkou, unconventional storage capacity list Longkou provided using first aspect present invention, can be guaranteed the quality in limited time
Guarantor measures closure in place, completes node tasks, and element task is carried out, while evaded due to joining the two sections of a bridge, etc unsuccessful for consumption engineering dregs
The people that need to additionally expend, material, machine loss.
The closure method of unconventional storage capacity list Longkou protection structure that second aspect of the present invention provides is using the present invention first
The unconventional storage capacity list Longkou protection structure that aspect provides, so as to the unconventional storage capacity Dan Long provided with first aspect present invention
All advantageous effects possessed by mouth protection structure.
