Abstract

The utility model relates to the field of industrial construction, in particular to a factory building column foundation in a reclamation area, including a column foundation body, which is characterized in that the longitudinally adjacent column foundation bodies are connected by concrete longitudinal connecting beams, and the horizontal span adjacent column foundation bodies They are connected by process jacking pipes. The process pipe jacking includes a support, a short pipe, an inner liner pipe and a drawing pipe. The supports are respectively arranged on the caps of the adjacent column foundations. Each support is provided with a short pipe, and the adjacent workshop column foundation There is a drawing tube between the short tubes, and a lining tube is provided at the connection between the drawing tube and the short tube. The outer diameter of the inner lining tube is in clearance fit with the inner diameter of the drawing tube and the short tube, and a pin is arranged on the outer diameter of the inner lining tube. , one end of the pin protrudes from the long hole at the end of the short tube. Compared with the prior art, the beneficial effect of the utility model is that the longitudinal deformation is limited by the use of longitudinal connecting beams, and the problem of excessive deformation caused by the lateral load of the column foundation of the workshop is solved by adopting the reusable process of pipe jacking, which saves steel Dosage.

Description

Factory building columns basis, reclamation area territory

Technical field

The utility model relates to the industrial construction field, is specifically related to factory building columns basis, a kind of reclamation area territory.

Background technology

At present; factory building columns foundation construction resist technology in reclamation area territory in industrial construction; mainly contain reinforced concrete wall, plastic concrete wall, hardened slurry wall, several from stiff mud slurry wall, dry wall, mud ditch wall (backfill gravel, clay and cement tabia), post-tensioned prestressing diaphragm wall, steel diaphragm wall etc.; but there is complicated construction technique in above body of wall; long construction period, economic benefit are not good.

Summary of the invention

The purpose of this utility model is to provide factory building columns basis, a kind of reclamation area territory, overcomes the deficiencies in the prior art, adopts the push pipe inner supporting structure, and is easy for installation when satisfying the enabling capabilities of construction process requirement, reusable, saves cost.

For achieving the above object, the utility model is achieved through the following technical solutions:

Reclamation area territory factory building columns is basic, comprises the upright post basic body, vertically is connected by the vertical coupling beam of concrete between the body of adjacent upright posts basis, is connected by the technique push pipe between the basic body of horizontal span adjacent upright posts.

Described technique push pipe comprises bearing, short tube, internal lining pipe and arm, bearing is located at respectively on the cushion cap of the basic body of adjacent upright posts, each bearing is provided with one section short tube, be provided with arm between the short tube on adjacent factory building columns basis, arm and short tube junction are provided with internal lining pipe, the internal diameter of the external diameter of internal lining pipe and arm and short tube is matched in clearance, and the internal lining pipe external diameter is provided with pin, and an end of pin is stretched out by the slotted hole of short tube end.

Described slotted hole length is 50～150mm.

Compared with prior art, the beneficial effects of the utility model are: utilize factory building columns basis body and vertically connect fine strain of millet raising stiffness characteristics and effectively limited longitudinal strain, adopt reusable technique push pipe to solve the caused distortion problems of too of factory building columns basis transverse load, effectively saved rolled steel dosage, reduce cost, increased economic benefit.

In figure: 1-upright post basic body 2-bearing 3-short tube 4-internal lining pipe 5-technique push pipe 6-concrete vertically connects fine strain of millet 7-arm 8-pin 9-slotted hole 10-pre-embedded bolt

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:

As Fig. 1, it is the utility model factory building columns foundation construction plane structure schematic diagram, upright post basic body 1 is positioned at the reclamation area territory, is connected by the vertical coupling beam 6 of concrete between the body 1 of its vertical adjacent upright posts basis, is connected by technique push pipe 5 between the body of horizontal span adjacent upright posts basis.Vertically connect span, cross section, the arrangement of reinforcement of fine strain of millet 6 according to factory building columns distance and load determination concrete, and concrete is vertically connected fine strain of millet 6 casting completes; Require and geological condition according to the factory building span again, determine the length of technique push pipe 5, according to diameter and the wall thickness of span and load calculating technique push pipe 5.

see Fig. 2, Fig. 3, the technique push pipe comprises bearing 2, short tube 3, internal lining pipe 4 and arm 7, bearing 2 is located at respectively on the cushion cap of the basic body 1 of adjacent upright posts, each bearing 2 is provided with one section short tube 3, be provided with arm 7 between the short tube 3 on adjacent factory building columns basis, arm 7 is provided with internal lining pipe 4 with short tube 3 junctions, the internal diameter of the external diameter of internal lining pipe 4 and arm 7 and short tube 3 is matched in clearance, internal lining pipe 4 external diameters are provided with pin 8, one end of pin 8 is stretched out by the slotted hole 9 of short tube 3 ends, the effect of internal lining pipe 4 is that arm 7 can be docked smoothly with short tube 3, during butt welding, internal lining pipe also plays the effect of back cover.Slotted hole 9 length are 50～150mm, and pin 8 is slided along slotted hole, drive internal lining pipe 4 and inject arm 7.

The construction guard method on factory building columns basis, the utility model reclamation area territory; because there is the risk of subsiding in the reclamation area territory; therefore the basic body of adjacent upright posts is connected respectively on vertical and horizontal; vertical and horizontal distortion with restriction upright post basic body; wherein the vertical concrete coupling beam is as permanent grade beam; laterally the technique push pipe is reusable structure, reduces construction cost, and the concrete installation steps of its horizontal technique push pipe are as follows:

1) pre-embedded bolt 10 on the cushion cap of the basic body 1 of concrete column, erection support 2 and short tube 3 are connected butt welding with arm 7 with short tube 3 by internal lining pipe 4;

2) cut from the butt welding commissure after arm 7, concrete complete in the construction of all underground foundations reaches design strength and terrace backfill compacting, so that recycling.
