Description
Technical field
The present invention relates to a kind of device and method that is used for foundation ditch deep layer soil excavation.
Background technology
Along with underground foundation depth more and more comes deeply, the soil excavation difficulty is increasing, particularly the excavation of the deep layer earthwork.The method that foundation ditch deep layer soil excavation is commonly used has at present: one, put sloping benching tunnelling method excavation; Two, high-front shovel (hydraulic grab) excavation method; Three, excavator excavation+crane lifting method.But these methods are in the shortcoming that all has self in varying degrees: one, put sloping benching tunnelling method excavation, soil layer is put the slope difficulty, and is subjected to weather effect bigger, if cutting depth is darker, the step of putting the slope is more, in the length limited system of the foundation ditch of putting sloping direction; Two, high-front shovel (hydraulic grab) excavation method, on the market exhibition arm after excavator (hydraulic grab) brachium the longest be 11.5 meters, high-front shovel (hydraulic grab) bucket is less, each shoveling is consuming time back and forth longer, efficient is lower, and is restricted aspect cutting depth, is obstructed at hard soil layer excavation, efficient is not high, and 1 machine-team is opened the about 500m of amount of excavation
3, One-Shift Costs is than higher, and 1 4500 yuan of machine-team (market price) is uneconomical; Three, excavator excavation+crane lifting method, excavation+lifting speed is too slow, and 1 machine-team is opened the about 300m of amount of excavation
3, be not suitable for generous amount excavation and overwork.
Summary of the invention
The objective of the invention is to solve the problem that above-mentioned several method self exists, a kind of high efficiency, economy are provided, maneuverability is operated easy deep layer earthwork excavating device and method thereof.
The objective of the invention is to be achieved through the following technical solutions:
A kind of device that is used for foundation ditch deep layer soil excavation, its characteristics are to comprise temporary steel platform that is arranged on the foundation ditch middle part and the excavator that is used for soil excavation, wherein the temporary steel platform is made by 6～10mm steel plate, length is 3～5m, width is 1.5～3.0m, highly be 0.5～1.5m, wherein the temporary steel platform advances native side direction and turns up 45 °～75 °, highly be 0.3～0.5m, draw the anglec of rotation of digging cubic metre of earth bucket in the temporary steel platform to adapt to excavator, same so that in the foundation ditch excavator earthwork is transported in the temporary steel platform, position, four angles of temporary steel platform is wrapped up in bag and is adopted Chain block to hang the wire rope of tying up on Guan Liang by wire rope respectively, at wire rope and concrete Guan Liang contact position pad adhesive tape, utilize the vertical position of Chain block lift adjustment temporary steel platform to reach steadily, the temporary steel platform that hangs in the foundation ditch replaces the step of putting sloping benching tunnelling method, terminal as soil excavation, also be convenient to stand in foundation ditch top excavator and vertically draw the earthwork of digging in the temporary steel platform, stand in the excavator of foundation ditch top and alternating floor soil excavation step, select the brachium of excavator according to the soil excavation degree of depth.
The method that is used for foundation ditch deep layer soil excavation of the present invention may further comprise the steps:
(1) foundation pit enclosure structure, operations such as first floor soil excavation and first and second road support construction are finished the about 6.5m of first floor earthwork thickness;
(2) hang the temporary steel platform, 2 groups of wire rope that are bundled on the Guan Liang are installed earlier, one group 3, every group of wire rope hangs 2 10t Chain blocks, according to the floor height of the earthwork, determine 2 groups of rope capacities of binding temporary steel platform, 4 suspension centres are hung on the hook of 4 Chain blocks, and 4 hoisting point positions are all set up wire rope, as the suspension centre of lifting, dismounting temporary steel platform, wherein the temporary steel platform advances native side direction and turns up 60 °, so that soil excavation and transhipment;
(3) the temporary steel platform hangs Guan Liang, calculate according to the brachium of first excavator that stands in the foundation ditch limit and to wrap up in bag temporary steel platform length of steel wire rope, and the vertical position that utilizes Chain block lift adjustment temporary steel platform reaches steadily, be fixed on waist rail position, second road, second excavator stands in the earthwork of the second layer soil end face excavation second layer, and be transported on the temporary steel platform, go on the transport vehicle by first excavator that stands in the foundation ditch limit and transport outward, wherein the thick 5.1m of the second layer earthwork;
(4) second layer earthwork is all finished or is excavated soil layer and forms step, three layers of native end face of the second excavator dive to the excavate the 3rd layer of earthwork, and transhipment is used to the temporary steel platform, go on the car by first excavator that stands in the foundation ditch limit and to transport outward, the 3rd layer of thick 4.9m of the earthwork wherein, the about 16.5m of cutting depth;
For accelerating construction progress, the second layer earthwork propelling that goes ahead, the 3rd layer of earthwork end face increases by 1 second excavator and excavates the 3rd layer of earthwork, increases temporary steel platform quantity simultaneously and gets final product.
Equally, can also hang the temporary steel platform in waist rail position, the 4th road, the 4th layer of earthwork is gone to the temporary steel platform, second excavator that stands in the 3rd layer of native end face will go on the second road waist rail temporary steel platform in the earthwork of waist rail position, the 4th road temporary steel platform, the rest may be inferred, hangs the temporary steel platform every one waist rail.
In order to accelerate soil excavation speed, in next waist rail position, excavation section second road one temporary steel platform is installed again, finish at last excavation section excavation, be convenient to form continuous productive process, and the temporary steel platform that will go up an excavation section moves to next excavation section.
The temporary steel platform replaces the rank, earthen platform, solves to put the sloping difficulty of putting of sloping benching tunnelling method, and is subjected to weather effect bigger, if cutting depth is darker, the step of putting the slope is more, is putting the problems such as foundation ditch length limited system of sloping direction; Excavation transhipment by excavator is cubic metre of earth to the temporary steel platform and draw to dig in the temporary steel platform and cubic metre of earth combine, it is less to solve high-front shovel (hydraulic grab) excavation method high-front shovel (hydraulic grab) grab bucket, each shoveling is consuming time back and forth longer, efficient is lower, restricted aspect cutting depth, be obstructed at hard soil layer excavation, efficient is not high, and 1 machine-team is opened the about 500m of amount of excavation
3, One-Shift Costs is than higher, 1 4500 yuan of machine-team (market price), problem such as uneconomical; Excavator excavation and transhipment solve excavator excavation+crane lifting method, and crane lifting speed waits problem too slowly.
The present invention is the continuity of putting sloping benching tunnelling method owing to adopt excavator and be arranged on the interior interim temporary steel platform of foundation ditch, is again the simplification that vertically goes out local method.Both continued and put sloping benching tunnelling method and the vertical advantage that goes out local method, solved the problem that self exists again.The present invention adopts the temporary steel platform in two excavators+be hung in foundation ditch, excavation pit degree of depth 16.5m, and 1 machine-team is opened amount of excavation 1000m
3More than, be not subjected to weather, put the influence of slope difficulty, simple to operate, effective, economic advantage fast.
The present invention is further illustrated below in conjunction with accompanying drawing.
