Abstract

A kind of prefabricated box prestressed slip-resisting pile, described antislide pile is made up of some pieces of prefabricated box-type members; This prefabricated box-type member is provided with presstressed reinforcing steel hole, each prefabricated box-type member block-by-block assembled shaping after each presstressed reinforcing steel hole on it be linked to be mutually through curved slot; Prestressed muscle in this curved slot.The utility model, owing to adopting prefabricate and install technology, shortens construction period, improves operating efficiency, meet the demand of the emergency repair disaster relief.And antislide pile adopts box-structure, reduce quantity of masonry, saved cost, adopt prestressing technique, improve the anti-slide performance of antislide pile.

Description

A kind of prefabricated box prestressed slip-resisting pile
Technical field
The utility model relates to antislide pile technical field, is specifically related to a kind of prefabricated box prestressed slip-resisting pile.
Background technology
Antislide pile is through the pile that sliding mass penetrates with sliding bed, and in order to a sliding force for gear gliding mass, playing stable side slope, be applicable to shallow-layer and medium-bedded landslide, is a kind of major measure of slide treatment.
In recent years, generally antislide pile is adopted in landslide control, various forms of antislide pile all occurs, show very strong AsA-GSH cycle, but, be all first excavation pit substantially, then reinforcing cage is tied up, last concreting, when strength of reinforced concrete reaches more than 80% by the time, competence exertion AsA-GSH cycle.And this stand-by period generally at least needs about 30 days, therefore, when the landslide for some accidents occurs, be difficult to accomplish timely control.
Utility model content
The utility model provides a kind of prefabricated box prestressed slip-resisting pile, avoids traditional antislide pile long construction period, the phenomenon that can not play a role immediately, can resist huge Thrust of Landslide simultaneously.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of prefabricated box prestressed slip-resisting pile, described antislide pile is made up of some pieces of prefabricated box-type members; This prefabricated box-type member is provided with presstressed reinforcing steel hole, each prefabricated box-type member block-by-block assembled shaping after each presstressed reinforcing steel hole on it be linked to be mutually through curved slot; Prestressed muscle in this curved slot.
Described prefabricated box component length 2-3m.
After each described prefabricated box-type member block-by-block is assembled into antislide pile, it is provided with spilled water hole on slide plane top near the side of massif; This spilled water hole and the assembled rear formation of each prefabricated box-type member block-by-block inner chamber through, be provided with dewatering installation in this inner chamber.
Described dewatering installation is water pump or inverted-siphon.
Described presstressed reinforcing steel is steel strand, and these steel strand are 3 bundles, 5 bundles or 7 bundles.
Each described prefabricated box-type member block-by-block is assembled into its upper end installation check well lid after antislide pile.
The utility model, owing to adopting prefabricate and install technology, shortens construction period, improves operating efficiency, meet the demand of the emergency repair disaster relief.And antislide pile adopts box-structure, reduce quantity of masonry, saved cost, adopt prestressing technique, improve the anti-slide performance of antislide pile.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that the utility model is arranged on sliding mass;
Fig. 2 is the utility model structural representation;
Fig. 3 is the A-A sectional drawing of Fig. 2;
In figure: 1 antislide pile, 2 liptinites, 3 sliding masses, 4 slide planes, 5 dewatering installations, 6 spilled water holes, 7 presstressed reinforcing steels, 8 ground tackles, 9 manhole covers.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of prefabricated box prestressed slip-resisting pile, described antislide pile 1 is made up of some pieces of prefabricated box-type members; This prefabricated box-type member is provided with presstressed reinforcing steel hole, each prefabricated box-type member block-by-block assembled shaping after each presstressed reinforcing steel hole (presstressed reinforcing steel hole site is determined according to antislide pile bending and shearing situation of change) on it be linked to be mutually through curved slot; Prestressed muscle 7 in this curved slot.Conveniently construct and lift by crane installation, each described prefabricated box component length is 2-3m.The long 3-6m in prefabricated box member exterior cross section, wide 2-4m, the long 1.5-3m in internal cavities cross section, wide 1-2m.Assembled shaping after the long 3-6m of antislide pile 1 outer cross section, wide 2-4m, the long 1.5-3m in internal cavities cross section, wide 1-2m.
After each described prefabricated box-type member block-by-block is assembled into antislide pile, it is provided with spilled water hole 6 on slide plane 4 top near the side of massif; This spilled water hole 6 and the assembled rear formation of each prefabricated box-type member block-by-block inner chamber through, be provided with dewatering installation 5 in this inner chamber.This dewatering installation 5 is water pump or inverted-siphon.Underground water is flowed in the cavity of antislide pile 1 by spilled water hole 6, fills 5 by draining, is discharged by underground water outside gliding mass slope body 3, reduces the thrust of sliding mass 3.
Described presstressed reinforcing steel is steel strand, and these steel strand are 3 bundles, 5 bundles or 7 bundles.Steel wire bundle is more, and skid resistance is larger.
Each described prefabricated box-type member block-by-block is assembled into antislide pile 1 its upper end installation check well lid 9 rear.What facilitate the later stage carries out inspection or maintenance in case.
Below for the antislide pile that 8 pieces of prefabricated box-type members are formed, illustrate the utility model implementation process.
Prefabricated: according to length 2-3m, be divided into 8 pieces prefabricated, each block is from lower end to upper end serial number.First assembling reinforcement cage, then according to hole making device (rubber bar) and the reinforcing bar in block prestressed muscle hole, hole making device is installed in strict accordance with presstressed reinforcing steel coordinate, and prefabricated box-type member needs health 28 days.For the 1st piece, the 4th piece, the 5th piece and last block, tension ground tackle 8 to be installed.
Excavation pit: excavation pit is greater than 20cm than the prefabricated box-type member length of side, according to geological condition, excavation pit will carry out snap close retaining wall.
Install: prefabricated box-type member need pass through installation, stretch-draw, slip casting twice cycling, general lifting appliance is adopted to install, presstressed reinforcing steel 7 to be installed anchoring before first piece of installation, later 2nd piece until the 4th piece is directly installed through presstressed reinforcing steel hole when installing, note seam and reserved opening docking, carry out first stage stretch-draw.Stretch-draw is complete carries out prestressing force slip casting, after slip casting is complete.Installing the 5th, 6,7 piece successively to last block the 8th piece, carry out stretch-draw, the complete grouting behind shaft or drift lining of stretch-draw.
Sealing off and covering anchorage works, and mainly meets and ensures termination ground tackle and presstressed reinforcing steel not by corrosion.
Build space concrete, in the space between reserved retaining wall and the antislide pile 1 be assembled into, build C40 stone concrete layer, improve antislide pile skid resistance.
