Abstract

The utility model relates to the technical field of guardrails, and in particular relates to a fixed direct burial type guardrail which comprises a guardrail vertical column, a soil layer and a concrete layer. The guardrail is characterized in that one end of the guardrail vertical column is positioned above the soil layer; the other end of the guardrail vertical column penetrates through the soil layer and is positioned inside the concrete layer; a concrete leveling layer is arranged below the concrete layer; and a broken stone hardcore is arranged below the concrete leveling layer. Compared with the prior art, the thrust face and the strength of the guardrail vertical column are improved as the tail end of the guardrail vertical column penetrates through the soil layer and is directly inserted into the concrete layer, and reinforcing bars penetrate through the tail end of the guardrail vertical column, so that the fixed direct burial type guardrail is applicable to severe weather.

Description

A kind of fixedly direct burial guardrail

Technical field

The utility model relates to guard bar technique field, specifically a kind of fixedly direct burial guardrail.

Background technology

Traditional guardrail is to be all directly connected with ground by cement, when running into the atrocious weathers such as typhoon, heavy rain, guardrail is easy to be flushed away or is blown down, and causes guardrail not play when separating traveling lane, increase the burden of traffic, directly affect driver's life security.

Summary of the invention

The utility model, for overcoming the deficiencies in the prior art, runs through dirt bed by the end of fence upright, is directly inserted into layer of concrete, and adopts reinforcing bar to run through the end of fence upright, and stress surface and the intensity of increase fence upright, make it more adapt to atrocious weather.

For achieving the above object, design a kind of fixedly direct burial guardrail, comprise fence upright, dirt bed, layer of concrete, it is characterized in that: one end of fence upright is positioned at the top of dirt bed, the other end of fence upright runs through dirt bed, be positioned at layer of concrete, the below of layer of concrete is provided with concrete leveling layer, and the below of concrete leveling layer is provided with hardcore bed.

The lower end of described fence upright is provided with reinforcing bar, and reinforcing bar runs through respectively fence upright from left to right and from front to back.

Described reinforcing bar is at least provided with 2.

Described layer of concrete is C20 concrete.

The utility model compared with the existing technology, runs through dirt bed by the end of fence upright, is directly inserted into layer of concrete, and adopts reinforcing bar to run through the end of fence upright, and stress surface and the intensity of increase fence upright, make it more adapt to atrocious weather.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

Referring to Fig. 1,1 is fence upright, and 2 is dirt bed, and 3 is layer of concrete, and 4 is reinforcing bar, and 5 is concrete leveling layer, and 6 is hardcore bed.

The specific embodiment

With reference to the accompanying drawings the utility model is described further below.

As shown in Figure 1, one end of fence upright 1 is positioned at the top of dirt bed 2, and the other end of fence upright 1 runs through dirt bed 2, is positioned at layer of concrete 3, and the below of layer of concrete 3 is provided with concrete leveling layer 5, and the below of concrete leveling layer 5 is provided with hardcore bed 6.

The lower end of fence upright 1 is provided with reinforcing bar 4, and reinforcing bar 4 runs through respectively fence upright 1 from left to right and from front to back.

Reinforcing bar 4 is at least provided with 2.

Layer of concrete 3 is C20 concrete.

The end of fence upright 1 is run through to dirt bed 2, be directly inserted into layer of concrete 3, and adopt reinforcing bar 4 to run through the end of fence upright 1, the intensity of increase guardrail, makes it more adapt to atrocious weather.
