Abstract

A pile shoe for a plastic drain board of soft ground treatment comprises a sleeve tube, a sheet iron and a section of iron wire. Two holes are drilled at the centering position of the iron sheet, and two ends of the steel wire are enabled to penetrate through the iron sheet, and are connected together on the backside of the iron sheet. A plastic drain board is enabled to penetrate out of the sleeve tube and then penetrate through gaps of the iron wire on the front face of the iron sheet, then the plastic drain board is reflexed, and a filtering net of the plastic drain board is fixed by a curved hook arranged on the head of the steel wire. The pile shoe for the plastic drain board of soft ground treatment is in a vertical state during a setting and establishing process, the iron sheet is enabled to become into a horizontal state by pulling and tightening the plastic drain board after a designed standard height is set, and therefore the upward pulling resistance of the pile shoe is improved, and anchoring effect of the plastic drain board is achieved very well, and rewinding is greatly reduced. The pile shoe for the plastic drain board of soft ground treatment is simple in materials, easy to process, low in cost and good in anchoring effect, is applied to a plurality of soil texture such as deep silt soil, dredger fill, artificial fill and tillage soil and the like, and can be widely used for soft soil foundation processing engineering.

Description

The shoe of a kind for the treatment of of soft foundation plastic draining board

Technical field

The utility model relates to a kind of Soft Ground instrument, specially refers to the shoe of the plastic draining board of a kind for the treatment of of soft foundation under the multiple geological condition.

Background technology

Plastic draining board adds vacuum method or the surcharge preloading method is one of the Soft Ground such as riverine and coastal area barged-in fill or mucky soil main method commonly used (discharging consolidation).In the method, setting of plastic draining board is the critical process that guarantees construction quality.According to the Plastic Drain Slab Construction rules, setting absolute altitude is the important indicator of Plastic Drain Slab Construction, and general employing shoe realizes the lower end anchoring in the engineering, thereby guarantees the absolute altitude that sets of plastic draining board.But in Practical Project, particularly in the deep ultra-soft muddy foundation, can't anchoring or rewind in the plastic draining board lower end is a problem that often runs into, and this will directly affect the sphere of action of plastic draining board and the reinforcement depth of ground, and settlement after construction can not meet the demands.

Summary of the invention

The purpose of this utility model will overcome the above problems exactly, the shoe of a kind for the treatment of of soft foundation plastic draining board is provided, be applicable to guarantee the absolute altitude that sets of plastic draining board, thereby improve workmanship under the multiple geological conditions such as deep silt soil, barged-in fill, artificial earth fill, cultivated matter soil.

The technical solution of the utility model is achieved like this: the shoe of a kind for the treatment of of soft foundation plastic draining board, comprise sleeve pipe 4, and be characterized in: it comprises a sheet iron plate 1, an iron leg silk 2; Be drilled with two holes in the centre position of sheet iron plate 1, sheet iron plate 1 passed at two of iron wire 2, and link together at the back side of sheet iron plate 1; Plastic draining board 3 is passed from the space of sheet iron plate front iron wire after sleeve pipe 4 passes, again with plastic draining board 3 reflexeds, consider net with iron wire head crotch fixed plastics band drain.

The utility model adopts disposable shoe that plastic draining board is carried out anchoring, the ground that is applicable to the multiple soil properties such as deep silt soil, barged-in fill, artificial earth fill, cultivated matter soil is processed, can solve efficiently, economically anchoring in the Plastic Drain Slab Construction, the problem such as rewind, guarantee the band drain construction quality in the Soft Ground engineering, reinforcing for the processing of soft foundation provides technical guarantee, in fields such as highway, municipal administration, port boats good application prospect is arranged.Compare with traditional plastic draining pile shoe, the utlity model has following advantage: (1) anchoring effect is good, rewinds little; (2) be applicable to the multiple soil properties such as silt soil, barged-in fill, artificial earth fill, cultivated matter soil, and be applicable to deep soft mud and the changeable soil layer of geology; (3) feeding is simple, and processing technology is simple, and the scene can be finished by hand; (4) on year-on-year basis under, cost is low.

The specific embodiment

The utility model comprises sleeve pipe 4, sheet iron plate 1, an iron leg silk 2; Be drilled with two holes in the centre position of sheet iron plate, sheet iron plate passed at two of iron wire, and link together at the back side of sheet iron plate; Plastic draining board 3 is passed from the space of sheet iron plate front iron wire after sleeve pipe passes, again with the plastic draining board reflexed, consider net with iron wire head crotch fixed plastics band drain.Notch at narrow edge, the lower end of described sleeve pipe short transverse cutting 75mm.Described sheet iron plate is of a size of 250 mm *, 150 mm *, 1 mm.Described iron wire is the long 6# iron wire of 20cm.

The size of sheet iron plate 1 is to determine by field trial repeatedly, and the difficulty of sinking when excessive sets power demand higher, and plastic draining board rewinds morely when too small, does not satisfy setting end absolute altitude requirement.Punch in the middle of sheet iron plate with artificial or machine, then bore a hole with iron wire, see Fig. 1, Fig. 2.

Board-plugging device telephone-moving location passes plastic draining board from sleeve pipe.Plastic draining board is passed from the space of sheet iron plate iron wire, the plastic draining board reflexed, require the iron wire space on the sheet iron plate front to want plastic draining board to be passed smoothly and with iron wire head crotch band drain is considered net to be fixedly connected with, see Fig. 3.

At the notch of narrow edge, the lower end of ordinary casing 4 short transverse cutting 75mm, acting as of this notch keeps vertically sheet iron plate in setting process, guarantees the verticality of plastic draining board, reduces the resistance that sets in the process, sees Fig. 3.

Use the self-propelled hydraulic board-plugging device that sleeve pipe is set to design elevation, after sleeve pipe sets design elevation, plastic draining board is promoted tension, because sheet iron plate one side is stressed, sheet iron plate becomes level by vertical state.As can be seen from Figure 4, sheet iron plate becomes the pressure that is subject to the earthing body after the level, makes iron plate not have large vertical displacement, thereby guarantees that plastic draining board can be anchored at design elevation well, and it rewinds greatly and reduces simultaneously.

Go up at last the pulling sleeve pipe, manually cut plastic draining board, guarantee the plastic draining board protruded length, telephone-moving is to next plastic draining sheet pile position.
