Abstract
The utility model relates to a prevent backward gushing drill way block structure after anchor rope final bore slip casting, include: steel sheet termination, disconnect-type crown plate, inflation stagnant water sand bag and non-woven fabrics, equidistant welded fastening of disconnect-type crown plate is served in the steel sheet termination, inflation stagnant water sand bag is arranged in between the disconnect-type crown plate, and the outer parcel non-woven fabrics of inflation stagnant water sand bag is served and is fixed in the steel sheet termination, the steel sheet termination is fixed in on the waist rail through leading to long fixing screw. The utility model has the advantages that: the utility model adopts the pre-buried steel sleeve, which is beneficial to reducing the disturbance to the surrounding soil body in the drilling process, and is safe and reliable; the utility model adopts the steel plate end-capping and expansion water-stop sand bag with the separated ring plate, which is favorable for tight orifice plugging, ensures that no back-surge condition occurs after anchor cable final hole grouting, and has good plugging effect; the utility model discloses structural installation is convenient swift, can adopt the site material to assemble, but reuse practices thrift the cost.
Description
Technical Field
The utility model relates to a prevent backward gushing drill way block structure after anchor rope final bore slip casting belongs to ground and foundation construction field, is applicable to foundation ditch engineering stake anchor construction engineering.
Background
Along with the development of cities, the utilization of underground spaces is more and more emphasized by people, the excavation depth of a foundation pit is more and more large, and ultra-deep foundation pit engineering appears. The ultra-deep foundation pits are often located in urban central areas, the surrounding environment conditions are complex, the protection requirements are high, and therefore the ultra-deep foundation pits are more and more emphasized by the engineering and academic circles.
In view of this, to the deficiency in the foundation ditch stock construction in the past, urgently need a new anchor rope end hole slip casting back to prevent gushing drill way block structure, prevent gushing effectually, improve the efficiency of construction, ensure that the construction is safe and reliable.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough among the prior art, provide one kind and have prevent that the effect of kicking is showing, install and remove characteristics such as simple etc. prevent kicking the drill way block structure after the anchor rope final bore slip casting.
The anti-backflow orifice plugging structure comprises a steel plate end sealing end, a separated ring plate, an expansion water-stopping sand bag and non-woven fabrics, wherein the separated ring plate is welded and fixed on the steel plate end sealing end at equal intervals, the expansion water-stopping sand bag is arranged between the separated ring plates, the expansion water-stopping sand bag is wrapped with the non-woven fabrics and fixed on the steel plate end sealing end, and the steel plate end sealing end is fixed on a waist beam through a through-length fixing screw.
Preferably, the method comprises the following steps: the fender pile is driven into the foundation pit, the waist beam is connected with the fender pile, a steel sleeve is arranged at the drilling construction position, and a drill rod is arranged in the steel sleeve.
Preferably, the method comprises the following steps: the three separate ring plates are distributed in a triangular shape on the sealed end of the steel plate.
The utility model has the advantages that:
1) the utility model discloses a pre-buried steel casing pipe helps reducing the disturbance to the soil body on every side, safe and reliable at the in-process that creeps into.
2) The utility model discloses a take steel sheet end capping and the inflation stagnant water sand bag of disconnect-type crown plate, it is tight to be favorable to the drill way shutoff, does not appear the anti-circumstances of surging after guaranteeing anchor rope final bore slip casting, and the shutoff is effectual.
3) The utility model discloses structural installation is convenient swift, can adopt the site material to assemble, but reuse practices thrift the cost.
