Abstract
Modified mixing material is anti-to lift river bottom protection block structure, purpose is the above mentioned problem for solving to produce in existing interlocking segment soft raft engineering use, it is prefabricated by using density material, improve fluoran stream surface soft raft structure, and add pressure relief vent, so as to forming a kind of new-type mixing material pressure-releasing type soft raft structure, the outside fluoran stream surface first row of existing interlocking segment soft raft group is arranged in, plays a part of that enhancing isostere is anti-to lift ability.The interlocking segment is placed in fluoran stream surface first row;The interlocking segment:Shaped upper part is the square tabular of top rake, and lower front side fluoran stream surface top rake, lower rearward side is lee side top rake, and lower front side thickeies;The pressure relief vent of insertion is provided between upper and lower surface;The prefabricated rope in interlocking segment inside simultaneously stretches out from rear side, is connected by rope in block with conventional soft raft bed protection structure below.
Description
Technical field
The utility model is related to a kind of prefabricated interlocking segment soft raft structure of pressure-releasing type mixing material.
Background technology
In conventional protection against erosion, guard, in the engineering of river bottom protection engineering, use soft raft as bed protection structure more.Soft raft by
Arrangement and ballast composition, arrangement is main to play soil conservation, and ballast, which mainly rises, to be resisted current, wave action, keeps soft raft
Stable effect, because it has preferably flexible, soil conservation performance and certain anti-current, anti-unrestrained ability.According to the difference of ballast,
In the river bottom protection soft raft pattern of prior art, concrete interlocking block soft mattress (CN 03229836.6) is a kind of important a large amount of
The river bottom protection soft raft structure used.
Regulating structure functional characteristic, geological conditions and hydrodynamic condition, the success or failure of engineering are heavily dependent on shield
The reliability at bottom, includes the stability of bed protection structure itself, and river bottom protection beach stability.Rationally determine the structure of soft raft
Pattern, ballast specification, remaining row's width, the structure safety and stably for ensureing construction time and validity period, realize that its soil conservation protects beach
Use function, reasonable controlled investment scale has important practical significance.
In the concrete interlocking block soft mattress of existing conventional techniques is arranged, using the concrete interlocking block for having pre-buried rope
It is used as ballast.The colligation ring that concrete interlocking block is reeved in reinforced bands is fixed on one with arrangement, with a row in blocks
The mode of laying, plays river bottom protection Bao Tan structure function.But in actual use, it is fast, big wave running into high current
During effect, stream soft raft is met by violent impact, isostere is left bottom surface under pressure effect because wave current is produced, started
Trend;And bottom surface is washed away under Action of Wave Current, make to produce hole between bottom surface and isostere structure, and further increasing is lifted
Trend, reaches that isostere is thrown after stability limit.
In engineering in practice, most take place lift be often outermost fluoran stream surface row's block, but be due to
First row lifts drive heel row, so as to result in the destruction of full wafer soft raft.Single soft raft lifts, and finally makes large stretch of river bottom protection
Structure function is lost, and further threatens the safety for protecting beach engineering.
The content of the invention
The purpose of this utility model is the above mentioned problem for solving to produce in existing interlocking segment soft raft engineering use, passes through
It is prefabricated using density material, fluoran stream surface soft raft structure is improved, and pressure relief vent is added, unloaded so as to form a kind of new-type mixing material
Pressure type soft raft structure, is arranged in the outside fluoran stream surface first row of existing interlocking segment soft raft group, is played enhancing isostere and is resisted
Lift the effect of ability.
Therefore, the technical scheme provided is:
A kind of modified mixing material is anti-to lift river bottom protection block structure, it is characterised in that this is anti-to lift river bottom protection block and be placed in and meet stream
Face first row;
It is described anti-to lift river bottom protection block:
Shaped upper part is the square tabular of top rake, and lower front side fluoran stream surface top rake, lower rearward side flows for the back of the body
Face top rake, lower front side thickeies;
The pressure relief vent of insertion is provided between upper and lower surface;
The prefabricated rope in interlocking segment inside simultaneously stretches out from rear side, passes through rope in block and conventional soft raft river bottom protection knot below
Structure is connected.
High density is formed after being prepared according to a certain percentage with technique with barium sulfate powder using conventional concrete in terms of material
Mixing material (not being the contribution part of technical solutions of the utility model, realized using prior art) it is prefabricated form, fully profit
The characteristics of with conventional concrete material and barium sulfate material, on the basis of volume and material cost is not increased, to isostere knot
Structure increases weight;Configuration aspects, fluoran stream surface increases the ability that structure confrontation current and wave current lift by thickening and top rake, and
By arranging pressure relief vent, further increase the resistance to overturning and anti-lifting property of structure.
The utility model has the advantages that:
(1) fluoran stream surface increase structural thickness and top rake processing, are shape after the silt underwashing of soft raft structure laying work area lower section
Into small-sized scour hole reserve, after generation is washed away, top rake is sunk in scour hole with soft raft structure, increase structural stability;
(2) by arranging pressure relief vent, active force of the water wave to soft raft block structure can be cut down, further increase knot
The resistance to overturning of structure and anti-lifting property.
The utility model can be used for dykes and dams protection against erosion, shore protection protection against erosion, bridge pier protection against erosion, river (sea) bed protection against erosion, shoal
Guard the protection against erosion such as (protection against erosion), Bao Tan (beach face is guarded, beach face protection against erosion), guard, river bottom protection engineering.
