Description

Collapsible loess compaction device

Technical Field

The invention relates to the field of building equipment, in particular to a collapsible loess compacting device.

Background

The collapsible loess refers to soil which undergoes significant additional deformation due to structural damage of soil after being soaked under the action of self-weight stress of an overlying soil layer or under the combined action of the self-weight stress and additional stress, and belongs to special soil. Some miscellaneous fill also has a collapsible nature. Collapsible loess is soil with special properties, uniform soil quality, loose structure and pore development. Generally, the strength is higher and the compressibility is lower when not wetted by water. When soaked by water under a certain pressure, the soil structure is quickly damaged, large additional subsidence is generated, and the strength is quickly reduced. When engineering construction is carried out on the collapsible loess foundation, the damage to engineering caused by additional settlement due to foundation collapse must be considered, and a proper foundation treatment method is selected to avoid or eliminate the foundation collapse or the damage caused by a small amount of collapse. The existing common method for building the roadbed aiming at the collapsible loess is to use an extrusion mode to extrude the moisture in the soil, so that the soil is ensured, but the existing extrusion device impacts from top to bottom through gravity, the working efficiency is low, and the construction efficiency is reduced.

Disclosure of Invention

In order to achieve the above purpose, the present invention provides the following technical solutions:

this crowded dense device of collapsible loess includes two rectangular plate-shaped fixed plates and the stripper plate that the size is the same, it has two tubular sleeves to correspond the equal perpendicular inlays in position on fixed plate and the stripper plate, it has the columniform guide arm of a plurality of sections to join in marriage in two pairs of sleeves, all through tubular connecting pipe and two bolt fixed connection between the guide arm, stripper plate one side is equipped with the platelike promotion baffle that the cross-section is the shape of hundred, it lives to promote the sleeve pipe parcel on the stripper plate of baffle, fixed plate one side symmetry is equipped with two L shape platelike supporting pad boards perpendicularly, two supporting pad boards yield sheathed tube position on the fixed plate.

Preferably, the fixed plate, the extrusion plate and the sleeve are all made of aluminum alloy, and the fixed plate and the extrusion plate are connected with the sleeve through welding.

Preferably, the guide rod and the connecting pipe are both made of aluminum alloy, and the guide rod and the connecting pipe are in clearance fit with the sleeve.

Preferably, the pushing baffle is made of aluminum alloy, and the pushing baffle is connected with the side face of the extrusion plate through welding.

Preferably, the supporting base plates are all made of aluminum alloy and are connected with the side faces of the fixing plates through welding.

The beneficial effect of adopting above technical scheme is: this crowded dense device of collapsible loess can dig out two parallel slots on collapsible loess when using, then pastes fixed plate and stripper plate respectively on two slots, and the guide arm is inserted to the festival in the sleeve pipe of past fixed plate to use connecting pipe and bolted connection guide arm in proper order to continue to insert, until the guide arm tip insert the sleeve pipe that the stripper plate corresponds, let the backing plate of support tightly withstand the opposite side of slot. And a hydraulic device is used for applying pressure to the pushing baffle plate to enable the extrusion plate to move towards the fixed plate, and the extrusion plate can move along the track of the sleeve and the guide rod to compact the collapsible loess between the fixed plate and the extrusion plate. This collapsible loess crowding device can dig the parallel slot of twice in advance, then extrudees the collapsible loess of two middle slots horizontally, lets the ground durable, improves the bearing capacity of ground.

FIG. 1 is a front view of a collapsible loess compacting apparatus according to the present invention;

fig. 2 is a plan view of a collapsible loess compacting apparatus according to the present invention.

The device comprises a guide rod 1, a fixing plate 2, an extrusion plate 3, a sleeve 4, a pushing baffle 5, a supporting base plate 6, a connecting pipe 7 and a bolt 8.

Detailed Description

The preferred embodiment of the collapsible loess compacting apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 and 2 show a detailed embodiment of a collapsible loess compacting apparatus according to the present invention:

combine fig. 1 and fig. 2, this collapsible loess crowding device includes two rectangular plate-like fixed plates 2 and the stripper plate 3 that the size is the same, it has two tubular sleeve pipes 4 to correspond all perpendicular inlays in position on fixed plate 2 and the stripper plate 3, it has a plurality of sections columniform guide arms 1 to join in marriage in two pairs of sleeve pipes 4, all through tubular connecting pipe 7 and two bolt 8 fixed connection of circle between the guide arm 1, it has two screw holes to open on the connecting pipe 7, 1 both ends side of guide arm has all opened two screw holes, the equal screw-thread fit of the remaining screw hole of bolt 8. One side of the extrusion plate 3 is vertically provided with a plate-shaped pushing baffle 5 with an inverted U-shaped section, the pushing baffle 5 wraps the sleeve 4 on the extrusion plate 3, one side of the fixed plate 2 is symmetrically and vertically provided with two L-shaped plate-shaped supporting base plates 6, and the two supporting base plates 6 give way of the position of the sleeve 4 on the fixed plate 2.
