Description
Technical field
The present invention relates to a kind of means of defence that can be applicable to the anti-ice erosion of cold region river.Belong to the anti-protector for collar that floating ice clashes into
Territory.
Background technology
The bank slope in the river that China's north latitude is more than 30 ° is usually present the problem of ice raft impact damage, and ice raft is to along journey bank
The shock on slope can directly cause channel-bank slumping or weaken the stability on river bank, thus causes soil erosion.At present, domestic bank slope
Protection many based on the protection of patch slope, and based on structures such as loose stone, stone masonry, precast slab, Reynolds mats, these
Patch slope bank protection structure does not consider the operating mode of ice raft impact damage when design, therefore in drift epoch, at the Ying Liuding in river
The section of punching can occur serious destruction.Loose stone, stone masonry and precast slab are loosely organized, globality is poor, conduct oneself with dignity little is to make
Becoming the main cause that it destroys, the whole property of Reynolds mat significantly improves, but its deadweight is little, upper surface is that double-decker causes friction
Power is greatly the main cause causing it to destroy.
Summary of the invention
The present invention be in order to solve existing slope sticking type safeguard structure " light, thin ", conduct oneself with dignity little, boundary strength is low, it is impossible to have
The problem that effect opposing ice raft clashes into.A kind of anti-ice erosion in Han Qu riverbank means of defence is now provided.
A kind of anti-ice erosion in Han Qu riverbank means of defence, it includes herein below:
First, in the case of ensureing that riverbank, slope is smooth, laying geotextile on riverbank, slope, at geotextile
Upper surface lays bottom layer of the reinforcing steel net, then multiple connection studs becomes blossom type arrange and is welded one end of multiple connection studs
Online at bottom layer of the reinforcing steel, lay multilamellar stone-laying on the net at bottom layer of the reinforcing steel；
Secondly, on the stone-laying completed paving top layer bar-mat reinforcement, then the other end by multiple connection studs is corresponding
Weld together with top layer bar-mat reinforcement, after interior welds completes, use multiple edge sealing reinforcing bar be uniformly arranged on top layer bar-mat reinforcement and
On two sides of bottom layer of the reinforcing steel net and the two ends of each edge sealing reinforcing bar are corresponding with bottom layer of the reinforcing steel net and top layer bar-mat reinforcement respectively
Weld together, be used for the stone-laying by blocking inside；
Again, by the disc uniform welding of multiple dome-type steel sheels on top layer bar-mat reinforcement, employing concrete capping will
Top layer bar-mat reinforcement covers, and only exposes the sphere of multiple dome-type steel sheel；
Finally, top and bottom on riverbank, slope build upward slope shoulder and solid foot respectively.
The invention have the benefit that
First riverbank, slope is compacted, it is ensured that in the case of riverbank, slope is smooth, riverbank, slope spreads the most successively
If geotextile and bottom layer of the reinforcing steel net, the inside that then multiple connection studs become blossom type be welded on bottom layer of the reinforcing steel net, putting
Put stone-laying, then lay top layer bar-mat reinforcement, and weld together with multiple studs that are connected, at the top layer bar-mat reinforcement laid and the end
Between two outsides of layer bar-mat reinforcement, uniform welding multiple edge sealing reinforcing bar is used for sealing stone-laying, then by multiple dome-type steel sheels
Disc uniform welding on top layer bar-mat reinforcement, use concrete capping by top layer bar-mat reinforcement cover, only expose multiple dome-type
The sphere of steel sheel；Finally, build upward slope shoulder and solid foot respectively in top and the bottom on riverbank, slope, be built into whole safeguard structure.
Wherein, geotextile is positioned at the bottom, has the effect preventing water from being emptied by bottom sandstone,
It is evenly arranged with between two sides and two sides of top layer bar-mat reinforcement lower surface on the online surface of bottom layer of the reinforcing steel
Multiple edge sealing reinforcing bars, and the plurality of edge sealing reinforcing bar links together for blocking from side by bottom layer of the reinforcing steel net and top layer bar-mat reinforcement
The stone-laying of the inside.
The means of defence using this safeguard structure to constitute, has the advantage that
1, bottom layer of the reinforcing steel net, top layer bar-mat reinforcement and stone-laying accumulation is used to get up, outside two bar-mat reinforcements bottom this safeguard structure
Side edge sealing reinforcing bar blocks stone-laying, and with connecting stud connection inside two bar-mat reinforcements, this structural integrity is good, structure is thick and heavy,
From great, the impact force of flowing ice raft can be effective against；
2, cover on top layer bar-mat reinforcement with concrete capping, in addition to protection top layer bar-mat reinforcement net, it is ensured that ice raft
More smooth with the contact surface of safeguard structure, effectively reduce the frictional force with ice sheet, beneficially Stability Analysis of Structures；
3, concrete capping is embedded in dome-type steel sheel and can be held up by ice raft, reduces ice raft and concrete surface
Contact area, reduces the frictional force of ice raft and concrete surface, alleviates the ablation destruction of concrete surface, and improves further
The coefficient of stability of structure；
4, the structure of the application cost compared with being specifically designed to the Reinforced Concrete Retaining Walls that opposing ice raft clashes into is lower, and steel
Muscle gabion can be arranged in winter construction, beneficially Design of Construction Organization.
The application gives full play to the performance of bar-mat reinforcement and concrete material, significantly improves the intensity of liner structure and stablizes
Property, effectively protection bank slope is not by ice raft impact damage.
