Abstract
The utility model discloses an auxiliary tool for the soft soil earthwork construction. The auxiliary tool comprises a box body which is composed of a channel steel frame, steel plates and twisted steel, wherein the steel plates are welded on top and bottom faces of the channel steel frame, and the twisted steel is welded on surfaces of the steel plates. During an excavation operation of a crawler excavator, two caterpillar stations are erected on a 'roadbed box' of the auxiliary tool, so that pressure on the soil is reduced; the 'roadbed box' is provided with good stiffness and skid resistant capabilities; the crawler excavator excavates on the 'roadbed box' as if the crawler excavator performs excavation operations on good soil layers. When the auxiliary tool is used under soft soil, the construction efficiency of construction machinery can be greatly improved, and good protection effects are provided for pile foundations.
Description
Technical field
The utility model relates to a kind of building aid, relates to a kind of aid that is used for earthwork construction specifically.
Background technology
The soft foundation geology characteristic is that soil body water content is big in the coastal area; Underground soil property is many moulds the mucky soil and the stream of state and moulds to be stream～and the silty clay of soft-plastic state is main, and soil property is soft, and intensity is low; Engineering properties is poor, has brought great inconvenience for the normal excavation and construction of machinery.Excavator stands directly on operation on the weak soil, have very big danger, and efficiency of construction is not high.
The utility model content
In order to solve the problem that exists in the prior art, the utility model provides a kind of aid that is used for the weak soil earthwork construction--subgrade case, overcomes on weak soil, the cut the earth problem of difficulty of crawler-mounted excavator in the prior art.
The technical scheme of the utility model is following:
A kind of aid that is used for the weak soil earthwork construction comprises casing, and said casing is welded on the steel plate of skeleton upper and lower surface by the channel-section steel skeleton, and the indented bars of surface of steel plate welding is formed.
The latticed skeleton that the channel-section steel that said channel-section steel skeleton is back-to-back welding more than four is welded into.
Indented bars on the said steel plate is to laterally arrange more than two.
The beneficial effect of the utility model is:
Crawler-mounted excavator is when digging, and two chain rails stand on " subgrade case ", to reduce the pressure to soil; " subgrade case " has good rigidity, and anti-slide performance, and crawler-mounted excavator stands in top digging, as stand in soil property preferably on the soil layer digging general; Under the weak soil geological conditions, use this aid, can improve the efficiency of construction of construction machinery greatly.
Adopt " subgrade case " auxiliary digging, 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 the weak soil, can increase work efficiency simultaneously.Anti-skidding effect is played in the setting of indented bars, avoids excavator because steel plate is peaceful and skid when water is arranged, and guarantees that excavator moves smoothly.
Adopt " subgrade case " auxiliary digging, save the excavator operation zone and change the operation of filling in soil, when digging inter-pile soil, the engineering piles peripheral to excavator plays the certain protection effect simultaneously, therefore can reduce construction cost.

Wherein 1---the channel-section steel of back-to-back welding;
Fig. 2 is the aid subgrade case upper and lower surface sketch map of the weak soil earthwork construction of the utility model;
Wherein 2---steel plate, 3---indented bars;
Fig. 3 is the subgrade case sketch map after making.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.
The aid " subgrade case " of the utility model weak soil earthwork construction adopts the thick steel plate of 6mm, and (1.6m * 4m), [16a channel-section steel, φ 16 indented barss are welded.Comprise casing, said casing is welded on the steel plate 2 of skeleton upper and lower surface by the channel-section steel skeleton, and the indented bars 3 of steel plate 2 surface soldered is formed.The channel-section steel skeleton is the latticed skeleton that the channel-section steel 1 of back-to-back welding more than four is welded into.The channel-section steel 1 of back-to-back welding at first is overlapped to form quadro frame, in framework, is welded into latticed then anyhow.Indented bars 3 on the steel plate 2 is to be welded in parallel on the steel plate 2 more than two, plays the anti-skidding effect of excavator.
" subgrade case " made in processing factory, makes the back and uses crane lifting, and automobile is transported to the job site.During the excavator digging, two each stations of chain rail are with a subgrade case, when excavator needs the shift position; " scratching bucket " of available excavator moved wherein one " subgrade case " earlier; After being put into the precalculated position, move other one again, in the excavator digging process; Can move " subgrade case " freely voluntarily, need not to join in addition crane gear.When a foundation ditch forwards another foundation ditch to, if distance is far away, with crane with automobile cooperation transporting.
The channel-section steel skeleton of the utility model also can directly use " H " shape steel to do; But " H " shape steel weight is greater than channel-section steel; Increased the overall weight of subgrade case, be more conducive to operation on weak soil, and excavator can be picked up subgrade case more easily and moves not as using channel-section steel.
This technology is applicable to littoral soft soil area, digging construction, and crane is suitable for during hoisting and hanging at the construction field (site), and can have enough to meet the need and recycle.
Although the utility model has been carried out foregoing description in conjunction with accompanying drawing; But the utility model is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, rather than restrictive; Those of ordinary skill in the art is under the enlightenment of the utility model; Under the situation that does not break away from the utility model aim and claim institute protection domain, can also make a lot of distortion, these all belong to the row of the protection of the utility model.
Claims (3)
1. an aid that is used for the weak soil earthwork construction comprises casing, it is characterized in that, said casing is welded on the steel plate of skeleton upper and lower surface by the channel-section steel skeleton, and the indented bars of surface of steel plate welding is formed.
2. the aid that is used for the weak soil earthwork construction according to claim 1 is characterized in that, the latticed skeleton that the channel-section steel that said channel-section steel skeleton is back-to-back welding more than four is welded into.
