Background technology
Discharging consolidation method has a wide range of applications in Soft Clay Foundation processing.In order to shorten drainage path, reduce solid The time is tied, needs to squeeze into vertical plastic draining board in ground.Plastic draining board is band-like composite structured, and centre is to be extruded into The two sides of the quilted plastic panel of type, core plate is that non-woven geotextile package makees filtering layer.Plastic draining board generally first connects casing It is interior, casing is driven by designated depth by plate machinery, then extracts casing, plastic draining board is left in the soil body, plane On generally according to square or equilateral triangle arrange, spacing be 0.7-2.0 meters.Horizontal direction drainage system is by horizontal sand bedding course And the chimney filter composition of embedment sand bedding course.Vertical drainage plate is connected with horizontal drainage system, forms complete drainage system.
Since casing causes surrounding soil during squeezing into the soil body larger disturbance, make under the infiltration coefficient of the soil body Drop is formed " smear zone (smear zone) ", and diameter is about 2.0-3.0 times of casing diameter.The presence of smear zone is significantly The rate of discharge for hindering pore water, causes consolidation time to increase.The scholars such as Abuel-Naga, which study, finds that heating can improve The infiltration coefficient of smear zone can greatly reduce the inhibition that pore water is discharged in smear zone, and solid by indoor large Consolidation time can be shortened by tying the heating of instrument verification experimental verification, while can increase final settlement.Typically now U-tube is used to note Water heats or drain bar winds electric-heating-wire-heating method, and complicated for operation and energy consumption is relatively high, therefore is not suitable for extensive scene Construction, it is therefore desirable to develop one kind and be suitable for live plate construction, and the higher hot type vertical drainage of heating efficiency is logical Road.
A kind of heating consolidation construction method of vertical drainage chimney filter in-built electrical hot pin is developed, electrical bar is placed on insertion ground In the vertical drainage chimney filter of base, during consolidation draining, electrical bar fever increases the smear zone soil body around vertical drainage chimney filter Temperature, increase the infiltration coefficient of the soil body, shorten consolidation time, while the final settlement during basement process can be increased Amount.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of vertical drainage chimney filter in-built electrical hot pin Ground heat discharge structure, utilize the ground heating discharge structure increase vertical drainage chimney filter around the smear zone soil body temperature Degree increases the infiltration coefficient of the soil body, shortens consolidation time, while can increase the final settlement during basement process.
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.
