Abstract

The utility model discloses a center-digging prestressed centrifugal tubular pile and square-pile soil case structure, which comprises a soil case and a soil borrowing drill rod penetrating through the inside of the soil case. A piston rod is fixedly arranged above the front surface of the soil case, a piston core is assembled inside the piston rod, the lower end of the piston core is connected to the upper side of a case door, two sides of the case door are mounted on slide rails on the soil case, the bottom end of the case door is clamped on a door catch plate, and the case door can slide on the slide rails by the aid of the piston core. A soil baffle plate is disposed inside the soil case. The center-digging prestressed centrifugal tubular pile and square-pile soil case structure has the advantages that soil is collected in a centralized manner, safety and civilization level of a construction procedure are improved, and the like.

Description

Middle pick prestressed centrifugally pile tube, side's stake earth box structure

Technical field

Pick prestressed centrifugally pile tube, side's stake earth box structure during the utility model relates to are mainly used in civilian and during industrial infrastructure builds, are used for reclaiming in the building piling process that fetches earth the device of earth.

Background technology

At present in civilian or communal facilities, in the process of construction of civilian or office premises, higher more stable in order to make that building is made, before building is set up, reinforcing to ground generally all is to assign into underground with pile tube or side's stake, play the effect of support of buildings, as pile tube or side's stake all is to be pressed in the soil by the mode that presses down generally, but because mode by pressing down, will produce object and press down soil compaction phenomenon in the process, simultaneously, the generation that presses down soil compaction in the process is squeezed for producing between the firmness of ground and pile body and the pile body, firmness to pile foundation exerts an influence, and the phenomenon of soil compaction makes the resistance that presses down strengthen again, is unfavorable for the sinking of pile body, therefore generally all be to realize piling in implementing now by the mode that presses down while fetching earth, be scattered everywhere but can produce earth in the process that fetches earth, cause construction uncivil, again the safety in the work progress is claimed simultaneously.

Summary of the invention

In order to overcome the deficiency of existing situation, can not satisfy the civilization degree of modern safety of construction and construction, the utility model is settled an earth case in original piling equipment, in fetching earth process, realizes in device that earth reclaims, keep the construction plant clean, improve middle pick prestressed centrifugally pile tube, side's stake earth box structure of safety of construction and civilization degree.

The utility model is to realize like this, middle pick prestressed centrifugally pile tube, side's stake earth box structure, comprise, the earth case, pass the drilling rod that fetches earth of earth case inside, the positive upper fixed of described earth case is provided with piston rod, and described piston rod internal configurations has piston core, and described piston core lower end is connected the chamber door top, described chamber door both sides are installed on the slide rail on the earth case, and described chamber door bottom is stuck on the knocker plate.

Described chamber door can slide on slide rail by piston core.

Described earth case inside is provided with breast boards, and the described drilling rod that fetches earth passes breast boards, and described breast boards is obliquely installed in earth case inside.

The utlity model has following remarkable advantages and characteristics:

1) has the cleannes that improve construction, improve the civilization degree of construction;

2) reclaim earth and help improving safety of construction, the unified recovery transported, and increases work efficiency.

Fig. 1 is the schematic diagram of pick prestressed centrifugally pile tube in the utility model, side's stake earth box structure;

Fig. 2 is the side explosion views of pick prestressed centrifugally pile tube in the utility model, side's stake earth box structure;

Wherein: 1-earth case; The 2-piston rod; The 3-piston core; The 4-drilling rod that fetches earth; The 5-slide rail; The 6-chamber door; 7-knocker plate; The 8-breast boards.

The specific embodiment

Pick prestressed centrifugally pile tube, side's stake earth box structure as shown in Figure 1, comprise, earth case 1, pass the drilling rod 4 that fetches earth of earth case 1 inside, described earth case 1 positive upper fixed is provided with piston rod 2, described piston rod 2 internal configurations have piston core 3, described piston core 3 lower ends are connected chamber door 6 tops, and described chamber door 6 both sides are installed on the slide rail 5 on the earth case 1, and described chamber door 6 bottoms are stuck on the knocker plate 7.

Described chamber door 6 can slide on slide rail 5 by piston core 3.

Described earth case 1 inside is provided with breast boards 8, and the described drilling rod 4 that fetches earth passes breast boards 8, and described breast boards 8 is obliquely installed in earth case 1 inside.

The utility model is to implement like this: drilling rod 4 fetches earth by fetching earth, the soil that takes out is reclaimed by earth case 1, all on breast boards 8, breast boards 8 moves on to certain position for being obliquely installed to soil after the recovery on earth case 1, enter piston rod 2 by piston core 3 contractions, chamber door 6 up moves, and earth is shifted out getting final product with soil by earth case 1, stretches out piston core 3, chamber door 6 is closed, and can reclaim earth once more.

It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this manual has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of the spirit and scope of utility model, and it all should be encompassed in the middle of the claim scope of the present utility model.
