Abstract
The utility model relates to a roadbed box for the earthwork construction of a large-sized tracked engineering vehicle. The roadbed box comprises a box body, wherein a framework of the box body is made of channel steel; the upper surface, the lower surface and a frame of the box body are respectively formed by steel plates welded on the framework; a closed cavity is formed by the steel plates positioned on the upper surface, the lower surface and the frame of the box body; longitudinally arrayed screw-thread steels and horizontally arrayed screw-thread steels are welded on the steel plates positioned on the upper surface and the lower surface; one side edge and one end part of the box body are respectively provided with two lifting lugs; a steel rope is arranged between the lifting lugs. The roadbed box disclosed by the utility model can provide a more even working plane for a tracked machine, thereby preventing the hazard that the tracked machine is sunk into soft soil. According to the roadbed box, a better anti-skid role is played through the arrangement of the longitudinal and horizontal screw-thread steels; the lifting lugs and the steel rope are arranged on a side surface and can be very conveniently hung on shoveling teeth of an excavator, so that the convenience for lifting is achieved.
Description
Technical field
The utility model relates to a kind of aid for earthwork construction, is specifically related to a kind of subgrade case for large-scale crawler engineering vehicle earthwork construction.
Background technology
In all kinds of construction sites, for improving the operating efficiency of engineering truck, engineering truck is also at continuous past maximization, crawler type future development, but large-scale caterpillar engineering vehicles is strict to walking ground, while in the large place of the soil body water content such as soft foundation, carrying out earthwork construction, underground soil property mainly with the mucky soil and the stream that are stream and mould state mould～silty clay of soft-plastic state is main, soil property is soft, intensity is low, and engineering properties is poor, has brought great inconvenience for the normal excavation and construction of machinery.The Construction traffics such as excavator stand directly on operation on weak soil, have very large danger, and efficiency of construction are not high.Therefore just need to lay on the ground corresponding base board, current way normally pads steel plate, but steel plate thickness thin mutability, often to arrive the even thicker ability of 100mm indeformable, such steel plate weight again heavy, carry inconveniently, cost is also high.
The utility model content
In order to solve problems of the prior art, the utility model provides a kind of aid for the weak soil earthwork construction--subgrade case, overcomes in prior art the crawler-mounted excavator difficult problem of cutting the earth on weak soil.
The technical solution of the utility model is as follows:
A kind of subgrade case, comprise casing, the skeleton of described casing adopts channel-section steel to make, and the upper surface of described casing, soffit and frame consist of the steel plate be welded on described skeleton respectively, and the steel plate of the upper surface of described casing, soffit and frame forms airtight cavity; On the steel plate of described upper surface and soffit, be welded with the indented bars of longitudinal arrangement and transversely arranged indented bars; One of them side of described casing and one of them end are respectively equipped with two hangers, between hanger, are provided with wire rope.
The beneficial effects of the utility model are:
Crawler-mounted excavator is when digging, and two chain rails stand on subgrade case, to reduce native pressure; Subgrade case has good rigidity, and anti-slide performance, and crawler-mounted excavator stands in top digging, as standing in soil property preferably on soil layer digging; Under the Soft Clay condition, apply this aid, can greatly improve the efficiency of construction of construction machinery.
In the side of subgrade case, be provided with hanger and wire rope, during construction, can hang over easily on the teeth of excavator, by excavator, be placed on the job location needed, and only need 2-3 piece subgrade case, just can, along with engineering progress, alternately be laid by excavator.
Adopt the auxiliary digging of subgrade case, can give comparatively smooth scope of operation of excavator, avoid excavator directly on weak soil, to cut the earth and be absorbed in the danger in weak soil, can increase work efficiency simultaneously.Better anti-skidding effect is played in the setting of indented bars in length and breadth, skids when avoiding excavator due to the steel plate peace and water being arranged, and guarantees that excavator moves smoothly.
Adopt the auxiliary digging of subgrade case, save the excavator operation zone and change and fill in native operation, simultaneously when digging inter-pile soil, the engineering pile of excavator periphery is played to certain protective effect, therefore can reduce construction cost.
The accompanying drawing explanation
Fig. 1 is the cage construction schematic diagram of subgrade case of the present utility model;
Fig. 2 is the upper surface of subgrade case of the present utility model and the steel plate structure schematic diagram of soffit;
Wherein, 1-channel-section steel, 2-hanger, 3-wire rope, 4-steel plate, the indented bars of 5-longitudinal arrangement, the indented bars that 6-is transversely arranged.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Subgrade case of the present utility model, comprise casing, and the skeleton of described casing adopts channel-section steel 1 to make, and the upper surface of described casing, soffit and frame consist of the steel plate be welded on described skeleton respectively, and steel plate adopts the thick steel plate of 6-8mm.The steel plate of the upper surface of described casing, soffit and frame forms airtight cavity, and while preventing from constructing under water environment, in case, water inlet, cause subgrade case to move difficulty.On the steel plate 4 of described upper surface and soffit, be welded with the indented bars 5 of longitudinal arrangement and transversely arranged indented bars 6, adopt φ 16 indented barss.One of them side of described casing and one of them end are respectively equipped with two hangers 2, between hanger 2, are provided with wire rope 3.The hanger 2 of side and wire rope 3 be at ordinary times handling, the hanger 2 of end and wire rope 3 alternately laying when constructing.The skeleton latticed skeleton that the channel-section steel 1 of many back-to-back welding is welded into of serving as reasons.At first the channel-section steel 1 of back-to-back welding is overlapped to form quadro frame, then in framework, anyhow is welded into latticed.
Because subgrade case is provided with wire rope 3, during construction, subgrade case does not need crane, can directly be lifted by the scraper bowl of excavator, by Automobile Transportation to job site.During excavator shoveling operation, article two, the chain rail is respectively stood with a subgrade case, when excavator needs shift position, the scraper bowl of the available excavator wherein subgrade case of first slinging, after being put into precalculated position, then move other one, in excavator shoveling operation process, can move voluntarily freely subgrade case, without separately joining crane gear.
This technology is applicable to the littoral soft soil area, digging construction, and crane is applicable during hoisting and hanging at the construction field (site), and can have enough to meet the need and recycle.
