Abstract
The utility model discloses a steel trestle for earthwork transportation of a foundation pit. The steel trestle for the earthwork transportation consists of supporting trestle frames, a supporting trestle surface and a supporting beam, wherein the supporting trestle surface is arranged at tops of the supporting trestle frames; the supporting beam is arranged at one end of the supporting trestle surface; the supporting trestle frames comprise vertical steel pipe piles, and transverse steel pipes and staggered stabilizing steel channels are arranged on the vertical steel pipe piles; the supporting trestle surface comprises a trestle surface steel frame, and a concrete slab surface is arranged on the trestle surface steel frame; the supporting beam comprises a steel plate, and deformed bars are arranged on the steel plate. Compared with the prior art, the steel trestle has the advantages of simple structure and convenience in operation, and a temporary, broken and cheap short steel structure channel which is relatively independent of a supporting structure of the foundation pit is constructed so as to meet requirements of earthwork excavation.
Description
Technical field
The utility model relates to a kind of steel trestle, particularly relates to a kind of pit earthwork transport steel trestle.
Background technology
At present, due to foundation ditch surrounding enviroment complexity, construction plant is narrow, and belong to huge ultradeep foundation pit engineering, therefore excavation of foundation pit adopts the support form of single cast-in-place concrete pile+tri-road reinforced concrete inner support beam+tri-axle cement mixing pile sealing (mud), it is the key point of deep foundation pit construction to soil excavation, for the huge ultradeep foundation pit soil excavation technology that has supporting and protection structure, the technology of current elongated employing has steel trestle technology or utilizes vertical transport equipment to promote, traditional steel trestle or carry indigenous equipment be unearthed, almost can meet the deep foundation pit earthwork digging engineering of various situations, but steel trestle need be from foundation ditch surface construction to foundation ditch at the bottom of, total bridge is long long, therefore working measure cost is relatively high, and it is lower to put forward the unearthed efficiency of indigenous equipment, so existing steel trestle Shortcomings.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, safe and reliable, save construction cost, accelerated construction speed, to meet a kind of pit earthwork transport steel trestle of soil excavation, overcoming the deficiencies in the prior art.
The utility model is to form like this: a kind of pit earthwork transport steel trestle, earthwork transport steel trestle forms by supporting crane span structure, support bridge floor and brace summer, be provided with support bridge floor at the top of supporting crane span structure, be provided with brace summer in one end of supporting bridge floor, support crane span structure and comprise vertical steel pile tube, on vertical steel pile tube, be provided with horizontal steel pipe and interlaced firm channel-section steel, supporting bridge face comprises bridge floor steelframe, on bridge floor steelframe, be provided with concrete plate surface, brace summer comprises steel plate, is provided with screw-thread steel on steel plate.
The angle L that supports bridge floor and foundation ditch ground is 10 °～15 °.
Earthwork transport steel trestle is made up of 2～3 support crane span structures.
On steel plate, be provided with 4～6 screw-thread steels.
Compared with prior art, the utility model not only has advantage simple in structure, easy to operate, and by a kind of interim,, short steel work passage broken end, cheap relatively independent with foundation pit supporting construction of construction, to meet the demand of soil excavation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of brace summer;
Description of reference numerals: 1-supports crane span structure, and 2-supports bridge floor, 3-brace summer, 4-vertical steel pile tube, the horizontal steel pipe of 5-, the firm channel-section steel of 6-, 7-bridge floor steelframe, 8-concrete plate surface, 9-steel plate, 10-screw-thread steel.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment of the present utility model: a kind of pit earthwork transport steel trestle, earthwork transport steel trestle forms by supporting crane span structure 1, support bridge floor 2 and brace summer 3, be provided with and support bridge floor 2 at the top of supporting crane span structure 1, be provided with brace summer 3 in one end of supporting bridge floor 2, support crane span structure 1 and comprise vertical steel pile tube 4, on vertical steel pile tube 4, be provided with horizontal steel pipe 5 and interlaced firm channel-section steel 6, support bridge floor 2 and comprise bridge floor steelframe 7, on bridge floor steelframe 7, be provided with concrete plate surface 8, brace summer 3 comprises steel plate 9, is provided with screw-thread steel 10 on steel plate 9.
Supporting bridge floor 2 is 10 °～15 ° with the angle L on foundation ditch ground.
Earthwork transport steel trestle is made up of 2～3 support crane span structures 1.
On steel plate 9, be provided with 4～6 screw-thread steels 10.
Of the present utility model cubic metre of earth of transport steel trestle one end is connected with brace summer 3, and the other end is connected with slight slope road.
The utility model is steel work, this passage adopts precast concrete plank except concrete plate surface 8, other composition members mostly are the steel members such as i iron, channel-section steel, round steel pipe, most of steel member can reclaim after passage is suitable for, to reduce construction cost, next this cubic metre of earth of transport steel trestle and foundation pit supporting construction are relatively independent, and foundation pit supporting project is minimized the impact of passage construction; This cubic metre of earth of transport steel trestle length is shorter, and steel trestle only extends to San road brace summer face absolute altitude; When soil excavation, build slight slope Lu Fangpo at the bottom of foundation ditch from steel stack end, slight slope circuit passes through from passage below, at channel end formation dish toroidal, puts the space that slope takies less in foundation ditch, is therefore referred to as " broken end steel trestle ";
The anti-bank of steel concrete is built in this cubic metre of earth of transport steel trestle both sides, in order to avoid surface channel dregs crashes into foundation ditch; And embedded steel tube, set up safe protective railing, play security protection, warning function.In the end cubic metre of earth ending stage, at channel end, the anti-bank of steel concrete is set, to avoid the hook machine slippage in surface channel.
