Abstract
An underwater drilling pile foundation protective cylinder comprises a cylindrical steel protective cylinder and blade pins arranged on the outer side of the bottom of the steel protective cylinder. The blade pins can be well fixed in riverbeds, achieve downward ground breaking and fixing functions, and serve as strengthening ribs to prevent the protective cylinder from deformation. The underwater drilling pile foundation protective cylinder has the advantages of simple fabrication process, low refitting cost, and high convenience, practicality and safety.
Description
Technical field
The utility model belongs to a kind of bridge construction rig under water, relates in particular to a kind of boring pile foundation casing.
Background technology
At present, bored pile foundation has become the main basic pattern in the bridge water, in the water there is the main job practices of drilled pile: boring method, steel sheet-pile cofferdam method, transportation by driving steel caisson method, trestle and underwater fixed platform method etc. on the ship.
The heterogeneity of mud matter cohesive soil easily causes local penetration under the riverbed, prevents that the casing bottom from seepage flow, piping, the anti-phenomenon of boring a hole outwards taking place, and casing tilts, depression and make, even causes the aperture to cave in.So the steel casing must sink to mud matter cohesive soil, the following enough degree of depth of lam impervious layer.There is certain defective in the steel casing of using in the construction now, can not well be applied in the bridge construction that riverbed earthen is complicated or The turbulent river crashes its way through, has very much very big potential safety hazard or improper use to occasion a delay the duration etc. if use.
The utility model content
The purpose of this utility model provides boring pile foundation casing in a kind of water that can be good at playing under water protective action.
In order to achieve the above object by the following technical solutions: boring pile foundation casing in a kind of water, comprise columniform steel casing, the bottom outside of steel casing is provided with the sword pin.
The end that the leg that have sharp sword of described sword pin for radially being provided with, leg have sharp sword stretches out steel casing bottom.
Described sword pin is provided with one week of bottom uniformly.
Described sword pin is 3.
Described sword pin also can be 4.
Described sword pin is that fixing lower end, steel casing bottom is the steel ring of sharp sword, and the internal diameter of steel ring equates with the internal diameter of steel casing.
Adopt the utility model, the sword pin can be good at being fixed in the riverbed, and the sword pin can play the downward effect of breaking ground, and can play the effect of permanent position again, and the sword pin in the riverbed also has the effect of reinforcing rib, prevents the casing distortion.Boring pile foundation casing manufacture craft is simple in the utility model water, and improvement cost is low, and is convenient, practical, the safety factor height.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, boring pile foundation casing in a kind of water, comprise columniform steel casing 1, the bottom outside of steel casing 1 radially is provided with 3 sword pin 2 that have sharp sword, the end that sword pin 2 has sharp sword stretches out steel casing 1 bottom, 3 sword pin are provided with one week of bottom uniformly, and the angle between each sword pin is 120 °.
Boring pile foundation casing in a kind of water, described sword pin is 4, the angle between two adjacent sword pin is 90 °.Other structures are with embodiment 1.
Embodiment 3
Boring pile foundation casing in a kind of water, described sword pin are that fixing lower end, steel casing bottom is the steel ring of sharp sword, and the internal diameter of steel ring equates with the internal diameter of steel casing.Other structures are with embodiment 1.
