Description

Foundation trench automatic damper

Technical field

The present invention relates to the working a kind of foundation trench automatic damper of urban discharging pipeline.

Background technology

Urban discharging pipeline construction has following characteristics conventionally: a narrow field, and excavation foundation trench does not generally possess the slope of putting condition, and big machinery is difficult to enter place; B pipe diameter is little, and excavation foundation trench is narrow; C excavation foundation trench is shallow; D obstruction is many, and irregular; E construction is simple, and fltting speed is very fast.Therefore,, when foundation trench excavation is below groundwater table and while there is the weak soil place that drift sand stream soil easily occurs and cave in, often need foundation trench Tu Bi to carry out supporting.

Conventionally the support pattern adopting has: put slope, baffle plate, Gravity Retaining Wall, outrigger base piling wall, sheet pile joist anchor and draw several supporting and protection structure such as (supports).Due to municipal construction condition, only have baffle plate and steel sheet pile feasible, but that steel sheet pile have construction machinery volume is large, be difficult to march into the arena, and the high feature of cost; Therefore not the engineering of particular importance, generally adopt baffle arrangement more.Combination baffle structure closure is poor, and time-consuming taking a lot of work, and speed of application is slower.

Summary of the invention

For above-mentioned situation, for overcoming prior art defect, the present invention's object is just to provide a kind of foundation trench automatic damper, and in the time of can effectively solving urban discharging pipeline construction supporting, supporting and protection structure cost is high, time-consuming taking a lot of work, the problem that speed of application is slow.

The technical scheme that the present invention solves is, comprise panel, crossbeam and double lead-screw, the plug-in formation baffle plate of compoboard on panel He Qi top, on baffle plate, there is crossbeam, on panel, there is the vertical beam being connected with crossbeam, the two ends of double lead-screw are connected between two crossbeams and vertical beam on baffle plate, on vertical beam, be fixed with and be placed in two gripper shoes between panel right-hand member, the right side of gripper shoe is close to be fixed with and is placed in two dividing plates between panel, on the left side wall of gripper shoe, be fixed with propulsion plant, the left end of propulsion plant leans in pipeline opening.

Automatic damper of the present invention is simple in structure, manufactures handling ease, and cost is low, volume is little, can Assembling, meet the condition in avenue construction, meet the feature of the fast transfer of pipeline construction, and combine easy for installation, flexibly, while meet meeting obstruction, adjust position.

The present invention is mainly comprised of integral part (claim not only panel), assembled plate (claim not only compoboard), crossbeam, inner support (but also claiming double lead-screw), propulsion plant five parts, integral part is in baffle plate bottom, two side shields and inner support connect into integral body, and height is determined by place major obstacle thing buried depth situation.Top is assembled by assembled plate, convenient dismounting, conversion while being convenient to meet obstruction.Integral part is connected employing slot with assembled plate, be convenient to fast dismantling and remove and installation.Inner support adopts double helix screw mandrel (or hydraulic cylinder).Propulsion plant is comprised of backing plate, hydraulic cylinder, hydraulic pump.

According to construction plant condition, automatic damper can be designed to monolithic or two kinds of patterns of Assembling.While thering is certain self-stable ability according to engineering geological conditions ,Dang stratum, automatic damper integral part is installed after being excavated to projected depth; When stratum does not have self-stable ability completely, after excavation 1-2m, put into integral part, then Bian Wa limit is sunk to, until projected depth.After integral part installs, according to obstruction situation ,Jiang top, top assembled plate, arrange and be arranged in the slot of bottom integral part; After assembled plate installs, crossbeam, inner support are installed in draw-in groove, according to foundation trench width adjustment mariages inner support length.Telescopic hydraulic cylinder is finally installed, and hydraulic cylinder one end is connected in the gripper shoe of integral part, and movable end withstands mounting pipe road junction backing plate.

Using method: after foundation trench excavation certain length, automatic damper is installed, cleaning foundation trench is to pipe laying after designing requirement, and after the 1st pipeline installed, tamped backfill, to requiring absolute altitude, is propped up baffle plate with excavation mechinery tethered sliding; After 2-3 root pipeline is installed, pipeline external surface with banket while thering is larger friction resistant resistance, movable end is bearing in mounted nose end, the mouth of pipe is installed backing plate.After this with foundation trench excavation direction, rely on hydraulic cylinder jacking baffle plate, follow-up excavation supporting foundation trench both sides Tu Bi, keeps soil wall stability in short-term, guarantees pipeline installation quality and construction safety; Driving space meets after the length of single pipe, and indentation hydraulic cylinder is installed pipe; And then repetition previous action, go round and begin again, until a line segment is transferred to next working face after finishing.As larger in propelling resistance, when thrust power is not enough, can partial demolition top combination baffle, or at baffle plate and native wall contact surface coating butter, reduce frictional resistance.When running into less obstruction and cross foundation trench, the place ahead, dismountable top combination baffle, along with propelling is converted and is continued to obstruction rear to use.Integral part overall length, should not be greater than 7.0ml, and protection segment length, gets 0.8ml conventionally; Construction section length, conventionally gets single pipe range and adds suitable installation, is generally not more than 4.0ml; Hydraulic feed device length, gets 0.5-0.8ml conventionally; Driving end-stopping plate length, gets 1.5ml conventionally.Combination baffle height, adopts 2.0-2.5m conventionally; Standing part height is got 2.00m conventionally; Height overall is not more than 4.50m.

When the present invention specifically implements, be to using the degree of depth as 4.5M is as basis, concrete engineering can be according to given calculating and check formula, voluntarily adjustment above.

1), structural meterials is ordinary steel except leading screw.

2), the thick 3mm of integral part panel, vertical stiffening rib 10*50mm, spacing 250mm.

3), assemble thickness of slab 3mm, vertical stiffening rib 6*50mm, spacing 250mm; Assembled plate bottom insertion end adds steel plate with 20mm.

4), ' work ' shaped steel, 6*12mm twice for crossbeam.

5), inner support adopts Φ 68mm double lead-screw (or hydraulic cylinder), is conducive to flexible modulation width, makes full use of, and saves material and cost, increase work efficiency; Meanwhile, when occurring, soil pressure is large especially, causes propelling at need, can suitably turn width down, reduces soil pressure.

6), hydraulic cylinder and hydraulic pump thrust are not less than 300T; Gripper shoe is welded by i iron; Nose end backing plate protective sleeve is made by 8mm steel plate.

Automatic damper of the present invention has following difference compared to shield machine: section configuration is square and for circular; Opened top, does not have closure; Driving is also what to separate with casting system, by ground excavation machine, completes driving.Major function is the effect of stablizing Excavation.Be mainly used in urban discharging pipeline installation; Be applicable to the soft soil layer that loose soil layer and mud, mucky soil etc. easily drift sand occur, cave in, groundwater table is especially applicable below, has particularly considered a difficult problem for the old pipeline complexity in city.The present invention has saved a large amount of artificial, has improved efficiency of construction; Reduced spillage of material; Reduced from many aspects cost.
