Abstract
A precipitation device of a manual dug pile comprises a columnar framework (5) which consists of a plurality of longitudinal reinforcing steel bars (1) and a plurality of annular reinforcing steel bars (2), wherein a filter screen (3) is arranged at the inside of the columnar framework, and the lower end of the columnar framework (5) is contracted into a pointed cone (6) which is downward; a bearing plate (7) is arranged at the top end of the columnar framework (5). The precipitation device can realize stratification advance precipitation in a manual dug pile hole, effectively improve the construction conditions of digging, and enhance the safety of construction.
Description
Technical field
The utility model belongs to the builing industry construction and uses supporting facility, relates to the precipitation device in a kind of hand excavated pile stake hole.
Background technology
Hand excavated pile is applicable to no underground water or less clay, the silty clay of underground water, and the argillic horizon that contains a spot of sand, sandy gravel, slurry calculus adopts, and is particularly suitable for loess formation and adopts.Because its stress performance is reliable, does not need large-scale plant, construction manipulation process is simple, and cost is lower, also often adopts during rich groundwater.When rich groundwater, infiltration or water yield are bigger, during the stake borehole, according to circumstances generally adopt following measure respectively: 1, seep water on a small quantity and in the stake hole, dig little sump,, muddy water is hung out together with cutting the earth with using well-bucket; 2, a large amount of infiltrations can be dug dark collecting well earlier in the stake hole, establish small-sized submersible pump underground water is discharged outside the stake hole, with cutting the earth with deepening collecting well; When 3, water yield was very big, with a leading excavation, underground water combined in this hole near making, and with submersible pump underground water is extracted out.Adopt said method, execution conditions are all poor, form quicksand under the situations of a large amount of infiltrations easily, and unsafe factor is more, and excavate 30-50 centimetre at every turn and just must carry out retaining wall deeply, and construction speed is slower.
The utility model content
The technical problems to be solved in the utility model is at the deficiencies in the prior art, to provide a kind of precipitation device of hand excavated pile, by the leading precipitation of layering in the stake hole of hand digging, the execution conditions when improving borehole, enhancing safety of construction.
The technical scheme that the utility model adopts for achieving the above object is, the precipitation device of described hand excavated pile comprises the column skeleton of being made up of many longitudinal reinforcements and multiple tracks steel hoop, described column skeleton inboard is provided with filter screen, its design feature is, the lower end of described column skeleton is punctured into a sharp cone distal and pointed cone down, and column skeleton top is provided with force bearing plate.
Below the utility model made further specify.
Referring to Fig. 1, the precipitation device of the utility model hand excavated pile comprises the column skeleton of being made up of many longitudinal reinforcements 1 and multiple tracks steel hoop 25, described column skeleton inboard is provided with filter screen 3, and its design feature is, the lower end of described column skeleton 5 is punctured into a sharp cone distal 6 and pointed cone down; Referring to Fig. 2 or Fig. 3, column skeleton 5 tops are provided with force bearing plate 7.
Referring to Fig. 4, the using method of the utility model device is, when hand excavated pile is excavated to the sand pebble layer of rich groundwater or mud, precipitation device of the present invention is hung in the hole 10, force bearing plate 7 is installed on the top of captation (that is column skeleton 5), adopt the mode of hammering that this precipitation device is squeezed in the sand pebble layer or mud to be excavated, the underground water in the soil layer enters the precipitation device through filter screen 3, adopts submersible pump in the precipitation device water to be extracted out again; Then the soil layer behind the precipitation is excavated, behind excavation one deck, the precipitation device is squeezed into one deck downwards, and then draw water, excavate, so circulation is until passing sand pebble layer or mud.Because of adopting the mode of hammering, this precipitation device squeezes into soil layer to be excavated, realize the leading precipitation of layering, made soil layer substantially dry when excavation of rich groundwater, improved execution conditions greatly, the quicksand phenomenon that has occurred easily when having avoided band water excavation has guaranteed the safety of constructing.
As known from the above, the utility model is a kind of precipitation device of hand excavated pile, and by the leading precipitation of layering in the stake hole of hand digging, the execution conditions when having improved borehole have strengthened safety of construction.

The specific embodiment
As shown in Figure 1, the precipitation device in the described hand excavated pile comprises the column skeleton of being made up of many (as five) longitudinal reinforcements 1 and multiple tracks (Ru Sidao) steel hoop 25, and described column skeleton inboard is provided with filter screen 3; The lower end of described column skeleton 5 is punctured into a sharp cone distal 6 and pointed cone down; Referring to Fig. 2 or Fig. 3, column skeleton 5 tops are provided with force bearing plate 7.Force bearing plate 7 can be made the structure that is similar to pile cover, correspondence promptly is set in the bottom surface of force bearing plate 7 is nested with reinforced cap 8 on each longitudinal reinforcement 1 top.
Referring to Fig. 1, the bottom of described sharp cone distal 6 can be provided with the stake point 4 of downward extension.
Described longitudinal reinforcement 1 and steel hoop 2 firm welding are formed skeleton.
The top of described longitudinal reinforcement 1 can exceed goes up steel hoop 2 most one so that with the flexible connection of force bearing plate.
Described filter screen adopts the press strip reinforcing bar to be fixed on the column skeleton.
