Abstract
The utility model relates to building materials of infrastructures, particularly relates to tubular piles in corrosive soil layers or underground water environments, and discloses an anti-corrosion device for tubular pile connecting joints in corrosive soil layers or underground water environments. A steel clamp ring surrounds the outside of an anti-corrosion coating at a connecting joint. The anti-corrosion device can be arranged at tube joint connecting positions of various tubular piles so as to provide anti-corrosion protection for steel end plates and welded joints of the tubular piles, and reduces soil layer friction destruction of anti-corrosion coatings on the tube joint connecting positions in a pile sinking process.
Description
Technical field
The utility model relates to the constructional materials of infrastructure, relates in particular to the pile tube in a kind of corrosivity soil layer or the groundwater environment.
Background technology
Because the steel end plate and the weld seam of existing pile tube connected node are directly exposed in soil layer or the underground water, its durability is affected in be corrosive soil layer or groundwater environment.Directly lay or the brushing erosion shield at the steel end plate and the weld seam outside, and directly lay or the brushing erosion shield in the pile tube outside, all can not avoid soil body friction destruction suffered in the pile driving process, be unfavorable for pile tube applying in be corrosive soil layer or groundwater environment.
Summary of the invention
The utility model is intended to address the deficiencies of the prior art, and pile tube connected node anti-corrosive apparatus in a kind of corrosivity soil layer or the groundwater environment is provided.The tube coupling junction that the utility model can be arranged on various pile tubes provides anti-corrosion protection for its steel end plate and weld seam, the erosion shield that reduces its top suffered soil layer friction destruction in pile driving process.
The utility model is achieved in that pile tube connected node anti-corrosive apparatus in a kind of corrosivity soil layer or the groundwater environment, and the node place that connects of described pile tube scribbles anticorrosive paint, and the anticorrosive paint periphery at described connected node place is wound with a steel hoop.
Pile tube connected node anti-corrosive apparatus in described corrosivity soil layer or the groundwater environment, described steel snap ring is had by two both sides that the semicircular feature that connects wing plate is spliced, described connection wing plate is fastened together with screw bolt and nut, and bending on the angle in the outside, bottom.
Pile tube connected node anti-corrosive apparatus in described corrosivity soil layer or the groundwater environment, it also comprises two location steel link stoppers, and they are welded on and connect between wing plate top and the pile tube, and described location steel link stopper external surface scribbles anticorrosive paint.
The utility model is put the tube coupling junction at various concrete tubular piles, the tube coupling junction of inner lining of steel pipe concrete tubular pile and the tube coupling junction between concrete tubular pile and the inner lining of steel pipe concrete tubular pile, and steel snap ring and anti-corrosion insulation inner liner can provide anti-corrosion protection for its steel end plate and weld seam.Anticorrosion node steel snap ring can reduce erosion shield suffered soil layer friction destruction in pile driving process of its top.The part of turning up steel snap ring both wings junction plate can reduce the soil layer shearing friction power that its top bolt and nut is subjected to when pile sinking.Location steel link stopper can stop the steel snap ring upwards to slide in pile driving process.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing:
Fig. 1 is a schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1: pile tube connected node anti-corrosive apparatus in a kind of corrosivity soil layer or the groundwater environment, anticorrosive paint 2 peripheries at described connected node place are wound with a steel snap ring 3.
Described steel snap ring 3 is had by two both sides that the semicircular feature that connects wing plate 4 is spliced, and described connection wing plate 4 is fastened together with screw bolt and nut, and bending on the angle in the outside, bottom.
It also comprises two location steel link stoppers 5, and they are welded on and connect between wing plate 4 tops and the pile tube 1, and described location steel link stopper 5 external surfaces scribble anticorrosive paint 2.
