Description
Technical field
The invention belongs to railway permanent ways maintaining technical field, is related to the device used during a kind of existing line base is reinforced, special
It is not related to a kind of quick ground extruding device of existing line base；The invention further relates to a kind of with the device rapid reinforcement existing line
The method of base.
Background technology
Roadbed directly affects the flat of rail as bearing track static load and the direct organization of DYNAMIC LOADING OF DRIVING TRAIN ON BRIDGES, the quality of its state
Along state.As orbital forcing is bad, it will cause rolling stock high vibration, wheel-rail force is multiplied, and seriously endangers
Track and locomotive component, or even cause train derailing to be toppled, jeopardize traffic safety.Therefore, the stability of roadbed is to ensure train
The basis of safe operation.Railway engineering belongs to typical linear rock structure, has diversity, laxity and layering otherness etc.
Feature, and along the line be in a variety of topography and geomorphologies, engineering geology, hydrogeology and climatic environment in, sometimes also by flood, wind and snow,
The influence of the disasters such as frost, change of its stable state to outside environmental elements is very sensitive, and especially train load, roadbed contain
The environmental key-elements such as water, temperature.
Both wired due to being limited by construction period technical conditions and construction investment, roadbed design standard is relatively low, such as road
Based filler, compacting criteria, drainage condition etc..Significantly carried with the increase and train of passenger-cargo freight volume and rolling stock axle weight
Speed, existing line base occurs rising soil, sinks, outer the various diseases such as squeezes.The stability of roadbed is had a strong impact on, is added foster
Maintenance load is protected, shortens the service life of rail superior portion structure, turning into influences safety of railway traffic and transport capacity raising
The main reason for.In the case of Line of Existing Railway and load-carrying are increased, embankment load condition changes, in line maintenance except pair
Outside subgrade defect is renovated, part roadbed is also needed to take reinforcement measure, to improve bearing capacity, but due to existing line
Transport power and capacity are very nervous, and roadbed treatment all has some difficulties to management from technology, both wired subgrade strengthening new technology
It is current urgent problem.
The content of the invention
, can be quick under driving condition it is an object of the invention to provide a kind of quick ground extruding device of existing line base
It is reinforcing road bed, neither influence train normal operation, and can rapidly and efficiently solve the problems, such as subgrade defect.
It is a further object to provide a kind of method with above-mentioned bracing means rapid reinforcement existing line base.
To achieve the above object, the technical solution adopted in the present invention is：A kind of quick ground extruding dress of existing line base
Put, include the frame of tubular, two bar holes are symmetrily processed with frame side wall, be placed with bar hole bar shaped not with frame
The compacted plate of connection, the both ends of frame are separately installed with end socket and hydraulic cylinder, and end socket is provided with bolt away from the side of frame；Edge
The length direction of compacted plate, compacted plate madial wall on be connected with three fixed seats；It is provided with along the axis direction of frame, frame
Base and connecting rod rest, base by two first connecting rods respectively with two blocks of compacted plates towards the fixed seat pin connection of base,
One connecting rod and fixed seat pin connection, base are located at one end of frame installation end socket；Connecting rod rest passes through two towards one end of base
Second connecting rod passes through two the 3rd with fixed seat pin connection centrally located on two blocks of compacted plates, the middle part of connecting rod rest respectively
Connecting rod is respectively with the 3rd fixed seat pin connection on two blocks of compacted plates, and connecting rod rest is away from one end of base and the piston of hydraulic cylinder
Bar is connected.
Another technical scheme of the present invention is：It is a kind of to be filled using the above-mentioned quick ground extruding of existing line base
The method for putting rapid reinforcement existing line base, it is specially：In existing line base disease position cross drilling, formation is horizontally through both
There is the prebored hole of roadbed；Quick ground extruding device is put into prebored hole, the bracing means is moved along prebored hole, when this is fast
Fast ground extruding device makes hydraulic oil enter in hydraulic cylinder, the piston rod of hydraulic cylinder stretches out, and pushes away after plan reinforcing position is moved to
Dynamic connecting rod rest moves to the direction away from hydraulic cylinder, in connecting rod rest moving process, promotes second connecting rod and third connecting rod around with connecting
The connected connecting pin of bridge rotates, while promotes compacted plate protruding, extrudes the hole wall of prebored hole, and reaming is compacted to meet design
After it is required that, hydraulic cylinder oil return, piston rod is bounced back, and connecting rod rest moves to towards the direction of hydraulic cylinder, and connecting rod rest is driven by connecting rod
Compacted plate retraction, then, bracing means is taken out from prebored hole, the prebored hole after formation is compacted；Prebored hole after compacted
Plasma device and pulp device are installed in both ends respectively, and cement mortar injected into plasma device, cement mortar by plasma device enter it is compacted after
Prebored hole in, until the concentration of cement mortar overflowed in pulp device approaches with injecting the concentration of the cement mortar in plasma device
When, stop slip casting；Inject it is compacted after prebored hole in cement mortar solidification after form pile body, the intensity of pile body meets that design is strong
After degree, plasma device and pulp device are removed；Repeat the above steps, horizontal composite foundation is formed at existing foundation diseases position, complete
The rapid reinforcement of existing line base.
Reinforcement means of the present invention is reinforced under conditions of driving is not influenceed to existing line base, greatly reduces operation
The scheduling pressure of unit, alleviates passenger and overstocks.Moreover, the prebored hole on existing line base, and to the soil body around prebored hole
Carry out compacted, improve subgrade rating for the first time；Slurries are poured into compacted prebored hole, form horizontal composite foundation, secondary raising road
Base bearing capacity, reduces the bearing capacity difference of existing line base after reinforcing to greatest extent, and supporting effect is uniform.And existing note
After slurry processes are reinforced, roadbed part bearing capacity differs greatly, uneven；Compared with existing slip casting method is reinforced, reinforced with the present invention
After method reinforces existing line base, the bearing power increase of existing line base about 40~55%.
