Abstract

The utility model relates to a construction appliance for tamping a super-short-shaped pile by use of building garbage. The lower end of the reinforced concrete pile of the utility model is connected with a lower tamping body, and the upper end is connected with an upper tamping body. The utility model adopts a basket-shaped hollow hammer, and a protecting barrel and a long hammer are arranged in the hollow hammer. The building garbage fillers are tamped. The utility model has low cost and short construction period, the construction quality can be easily controlled, and the utility model is widely used for industrial factories and residential area buildings and is suitable for constructing in the bad foundation.

Description

Ram the construction equipment that expands ultrashort abnormity stake with building waste

The utility model relates to the foundation treatment technology field.

At present, it is to tamp or filling tamped at the ground shallow-layer that existing weight rams, because the effect energy is to transmit from top to bottom, it is limited to influence the degree of depth, and in the compacting process, portion of energy causes the soil body in the surperficial certain limit to produce shear failure, causes earth heaving to be extruded, compacting body leakiness, will select the bearing stratum that adapts to deposited reinforced concrete pile the time, in the coastal area, bearing stratum is generally darker preferably, long have to select very long of stake, about 20～80 meters, cause construction costs very high, in addition, because deposited reinforced concrete pile is only paid attention to the bearing stratum of deep layer, and has ignored ground floor preferably.

The purpose of this utility model is to overcome the deficiency of above-mentioned known technology, thereby a kind of construction equipment that expands ultrashort abnormity stake that rams with building waste is provided.

The purpose of this utility model realizes in the following way:

This device comprises following compacting body, reinforced concrete pile (3) and the upper punning body of being made up of building waste (1) and stiff concrete (2) (4), wherein: reinforced concrete pile (3) lower end links to each other with following compacting body, inside has reinforcing cage (6), and the top connects upper punning body (4) and cushion cap (5).

The upper punning body place of this device also is provided with a hand basket shape punching hammer (9), has casing (8) in the punching hammer (9), is with long hammer (7) in the casing (8).

During work, with punching hammer compacting surface layer, form upper punning body, earlier as the last bearing stratum of ultrashort stake; Use the Guan Zhongchang hammering blow to design level again, ram, tamp body down one of underground formation with the weight filler, as the following bearing stratum of ultrashort stake, treat down to tamp body ram closely knit after, descending reinforcing cage in pipe, concrete perfusion is carried the Guan Houyong vibrator and is carried out vibration compacting, forms ultrashort abnormity stake.

The utility model compared with prior art has following advantage:

1. cost is low, has adopted construction waste rubbish, when natural foundation capability can not meet design requirement, adopts this scheme cost minimum in tier building, even also lower than the not treated scheme that can adopt structural measure to handle.

2. the duration weak point is generally handled floor space 700～800m ²The ground of six-storey building only need 7～10 days, less to rainy season construction influence in winter.

3. construction quality is easy to control.

Generally have only 3～5m because of this stake, ram building waste with weight in pipe, weight is mentioned certain altitude when finishing, when requiring pile penetration to be definite value, can make that inhomogeneous ground is treated to be reached evenly, the impression pile bearing capacity is all identical, because stake is long only to be 3～5m, be difficult for taking place accidents such as broken pile.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the utility model front view.

Fig. 2, Fig. 3, Fig. 4 are that the master of hand basket shape punching hammer looks, looks up, vertical view

Fig. 8 to Figure 16 is a process chart of the present utility model.

In Fig. 1: (1) building waste; (2) stiff concrete; (3) steel concrete bolt; (4) compacting body; (5) cushion cap; (6) reinforcing cage.

In Figure 14: (7) long hammer; (8) casing; (9) punching hammer.

Embodiment:

Manufacturing process of the present utility model is as follows:

1) unwrapping wire, location, manually digging hole; (see figure 8)

2) lay the punching hammer; (Fig. 9)

3) put casing in the punching hammer; (Figure 10)

4) put into building waste in the casing and ram, make casing down to one with long hammer

Allocation; (Figure 11)

5) mention punching hammer and under it, fill out building waste; (Figure 12)

6) upper punning body forms; (Figure 13)

7) carry long hammer, filler, ram, make casing down to design elevation, and continue

Ram, filler, form compacting body down, long hammer is proposed; (Figure 14)

8) transfer reinforcing cage, throw concrete; (Figure 15)

9) propose casing, punching hammer, use the vibrator vibrated concrete, ultrashort abnormity stake

Form; (Figure 16)

Claims

1. construction equipment that ram to expand ultrashort abnormity stake with building waste, comprise following compacting body, reinforced concrete pile (3) and the upper punning body (4) formed by building waste (1) and stiff concrete (2), it is characterized in that: reinforced concrete pile (3) lower end links to each other with following compacting body, inside has piano cage (6), and the top connects upper punning body (4) and cushion cap (5).

2. device according to claim 1 is characterized in that: the upper punning body place also is provided with a hand basket shape punching hammer (9), has casing (8) in the punching hammer (9), is with long hammer (7) in the casing (8).
