The utility model is achieved through the following technical solutions:
A kind of ground heating discharge structure of vertical drainage chimney filter in-built electrical hot pin, including vertical drainage chimney filter and electric heating
Stick, the vertical drainage chimney filter are made of the terylene spun-bonded non-woven fabrics of permeable bellows and the permeable bellows of package, vertical drainage
Chimney filter is vertically arranged in ground, and the electrical bar is inserted into vertical drainage chimney filter, and electrical bar passes through insulative water-proof quick plug
Lead be connected, and insulative water-proof quick plug is connected with the quick coupling of T-type cable, T-type cable and power supply system
It is connected.
In the above-mentioned technical solutions, it is in ripple that the permeable bellows, which is by the external form that high density poly propylene (PPR) is formed,
The groove of the novel water drainage plastics tubing of shape, permeable bellows is evenly distributed with permeable through-hole, and permeable bellows surrounding outsourcing terylene is spun
Bonded non-woven fabrics.
In the above-mentioned technical solutions, the electrical bar uses quartz heating stick or ceramic heating bar.
In the above-mentioned technical solutions, electrical bar length should be identical as vertical drainage chimney filter length.
It the advantages of the utility model and has the beneficial effect that:
The utility model places electrical bar in vertical drainage chimney filter, in the base for not influencing chimney filter itself drain function
On plinth, make chimney filter while being provided with electric heating function, heating structure leakproofness is strong, waterproofing grade is high, and the electrical bar is constructed
Simply, easy to connect.
The temperature that the smear zone soil body around chimney filter is increased using vertical drainage chimney filter in-built electrical hot pin, accelerates consolidation draining
Rate shortens consolidation time.
Vertical drainage chimney filter uses tubular structure, facilitates and is squeezed into ground using plate machinery, itself can compress suitable
Answer the sedimentation during basement process.And vertical drainage chimney filter and electrical bar are split structure, vertical drainage chimney filter is inserted into ground
Vertical inner space is formd after base, then facilitates and electrical bar is placed in vertical drainage chimney filter, avoids plate process pair
In the destruction of electrical bar.It is simple in structure compared with heating wire winding formula heats drain bar, it is convenient for site operation and protection.
