Description
Technical field
The present invention relates to a kind of canal formulas to cut cement soil wall field, and in particular to a kind of canal formula cutting cement soil wall equipment
Chain saw case cutting body buried after rise draw out method.
Background technique
Architecture field is that the building underground space carries out earth-retaining, sealing using canal formula cutting cement soil continuous wall (TRD), for
The underground space go along with sb. to guard him the advanced technology of construction.It includes host and chain saw case cutting body, chain that canal formula, which cuts cement soil wall equipment,
Saw case cutting body includes tool post, the cutter chain being mounted in tool post and is removably arranged on cutter chain
Cutting tool line.The chain saw cabinet that tool post is sequentially connected from top to bottom by several forms, between two neighboring chain saw cabinet
It is bolted.Cutter chain is cricoid chain and around chain saw case cutting body, and by the top of tool post with
The sprocket wheel of bottom, the sprocket wheel rotation at the top of host driven tool post, and then the rotation of cutter chain forward or backwards is driven, from
And have the function that cutting, the stirring soil body.
Chain saw case cutting body cuts to the specified stratum of design in vertical direction, then carries out transverse cuts foundation soil, and
Cement slurry or other solidify liquids are injected, the continuous soil cement sealing wall for being allowed to be formed a uniform thickness (completes side to enclose
Block underground water)；After the wall is inserted into fashioned iron or other hard metal rod pieces, become i.e. sealing, and the cement soil of energy earth-retaining
Lower diaphragm wall.
When canal formula cutting cement soil continuous wall is constructed in sand gravel stratum, due to the sand gravel stratum pine in stratum
It dissipates, is often High water cut stratum, collapsing for sand gravel stratum often occurs in construction under the top interface in underground water again
It collapses, buries the failure of chain saw case cutting body.For example, in the construction process, if there is no admixture quantitative very well when cuts formation
The failure that slurries interrupt occurs when stirring spraying cement slurries for bentonite, easily generates the collapsing of sand gravel stratum, buries chain
Saw case cutting body.
Reach tens of rice when chain saw case cuts body length, or even longest chain saw case cutting body has reached more than 60 meters at present
In the case of, be embedded in sand gravel stratum, chain saw case cutting body rise pull out just it is extremely difficult；Especially in the process of water-spray type slurry
In, it collapses, after chain saw case is buried, since the intensity of soil cement is enhancing over time, and soil cement and chain
The cohesive force of saw case is enhancing, i.e., can not also be risen using up to a hundred tons of hydraulic jack cooperation with the crawler crane of large-tonnage and pull out chain saw
As a result case cutting body can only be abandoned, cause the loss of members up to a million and needs take measures to take other measures to this region
It is remedied.
Summary of the invention
The purpose of the invention is to provide one kind can smoothly mention the chain saw case cutting body being embedded in soil cement
Rise the draw out method after the chain saw case cutting body salvaged to the canal formula cutting cement soil wall equipment on ground is buried.
The technical scheme is that
A kind of chain saw case cutting body of canal formula cutting cement soil wall equipment buried after play draw out method, chain saw case cutting body includes knife
Tool column, the cutter chain being mounted in tool post and the cutting tool line being removably arranged on cutter chain, cutter
Row includes blade row bottom plate, at least two cutter heads and the connection knife bar that cutter head Yu blade row bottom plate are corresponded and connect with cutter head, canal
Formula cutting cement soil wall equipment chain saw case cutting body buried after rise draw out method successively the following steps are included:
First, after chain saw case cutting body is buried, keeps cutter chain rotating once after setting time t1 hours, prevent
Cutter chain is consolidated by soil cement；
Second, within the time that cutter chain stops operating, at least one that will be located on the cutter chain above earth's surface is cut
Blade row disassembly, then, the cutting tool line of disassembly is reversely installed on cutter chain, cracks dress to be formed on cutter chain
Set, formed in the cutting tool line of breaking device: cutter head, connection knife bar and cutter chain are located at the same side of blade row bottom plate, and knife
Tool column is located between two connection knife bars of arbitrary neighborhood；
Third, canal formula cut cement soil wall device drives cutter chain rotation at least one circle, cutter chain-driving breaking device around
Chain saw case cutting body rotates synchronously, and soil cement is cut, to form ring-shaped groove between chain saw case cutting body and soil cement；
4th, the cutter head on the connection knife bar in the cutting tool line of breaking device is cut down, then, lengthens connection knife bar,
One section of lengthened tool arbor is welded in connection knife bar end, forms new connection knife bar；Followed by the cutter head cut down is welded to
The end of new connection knife bar；
5th, third step is returned, chain saw case cutting body is made to be kept completely separate or be partially separated with soil cement or soil layer.
This programme canal formula cutting cement soil wall equipment chain saw case cutting body buried after rise draw out method, by making chain saw
Case cutting body is kept completely separate or is partially separated with soil cement or soil layer, to will smoothly be embedded in the chain in soil cement or soil layer
It saws case cutting body and promotes salvaging to ground, avoid economy caused by due to chain saw case cutting body is embedded in soil cement or soil layer
Loss.
Preferably, further comprising the steps of: the 6th, chain saw case cutting body is sling by loop wheel machine.
Preferably, loop wheel machine slings chain saw case cutting body disposable in the 6th step.
Preferably, the chain saw cabinet that tool post is sequentially connected from top to bottom by several forms, two neighboring chain saw
It is bolted between cabinet, in the 6th step, when loop wheel machine slings chain saw case cutting body in such a way that interval is lifted by crane,
Have a rest lifting mode it is as follows: after one of chain saw cabinet is lifted out ground, loop wheel machine stops working, and then, will be lifted out
One piece of chain saw cabinet disassembly behind ground, and removed the chain saw cabinet of disassembly by loop wheel machine；Repeatedly, until by entire chain
Saw case cutting body is lifted out ground.
This programme is conducive to chain saw case cutting body being lifted out ground.
Preferably, the length of lengthened tool arbor is less than or equal to 10 centimetres.
The beneficial effects of the present invention are: smoothly the chain saw case cutting body being embedded in soil cement or soil layer can be promoted
It salvages to ground, avoids economic loss caused by due to chain saw case cutting body is embedded in soil cement or soil layer.
