Description
Technical field
The utility model relates to a seed capsules bag constructions device, particularly a kind of double hose capsule bag constructions device belongs to the construction of tunnel technical field.
Background technology
The pipeline section foundation construction is the immersed tunnelling method tunnel, particularly one of difficult problem of immersed tunnelling method constructing tunnel.From the development of immersed tunnelling method tunnel basis construction technology, the pipeline section foundation construction method is broadly divided into first shop method and shop, back method.Elder generation's shop method comprises shop method and the pile foundation method of scraping; Back shop method comprises sand-blast, presses sand method, mud jacking, sand replacement method and filling capsule method etc.Pile foundation method in the method for wherein first shop is mainly used in the soft foundation substratum, back-silt area, river etc. can make pipeline section produce the occasion of differential settlement by force, or the tunnel that builds up uses the back to make the occasion of grittiness basis liquefaction because of vibration.Pile foundation construction at first will consider how to make the plan-position of stake, stake top mark height to meet design requirement under water, makes closely connected the coincideing in bottom of stake top and pipeline section.Usually adopt more having: underwater concrete power transmission method, mortar capsule bag power transmission method and adjustable stake top method.Wherein mortar capsule bag power transmission method is exactly between pipeline section bottom and stake top the capsule bag to be set, and is padded through the cement injection mortar, makes all pile foundations energy simultaneously stressed.The effect of capsule bag is vital in this job practices, and this tunnel, Taide, the court of a feudal ruler of Sweden just adopts the method to carry out the pipeline section foundation construction.By literature search: the construction of this Taide immersed tube tunnel of the Sweden court of a feudal ruler of mentioning in " catalogue of immersed tube tunnel and archives material ": " ... tunnel maximum subsidence great majority occur in early days, and scope is between 40mm～50mm.Abutment wall and top have tiny crack to take place, and cathodic protection was once repaiied once again, the direct about 10mm of depression after the sinking; After the backfill, depression increases to 20mm (the about 50KN/m of the overload of backfill
2) ... "Include immersed tube tunnel report (P159 page or leaf) in 1997 in " world's immersed tube technology " (second phase) international tunnel association.By analysis, occurring certain sinkage behind the constructing tunnel may be relevant with the following deficiency and the defective of this job practices: 1. the capsule bag adopts nylon to make, and it is bigger that it prolongs the rate of expanding, and influence the even filling of the interior mortar of capsule bag.2. the consistency of mortar value height that is pressed in the bag, shrinkage factor is big.After mortar is full of the capsule bag, because fixed contraction is difficult to guarantee capsule bag and pipeline section closely connected joining of bottom.3. in the capsule bag during pressure injection mortar, unnecessary water, gas can not be discharged simultaneously in the bag, causes mortar filling fully densely and full capsule bag.Add the fixed contraction of mortar, more increased the gap of capsule bag and pipeline section bottom.
Summary of the invention
The purpose of this utility model is to provide a kind of double hose capsule bag constructions device that is used for immersed tunnelling method tunnel pile foundation, it is at the deficiencies in the prior art and defective, can get rid of unnecessary water and air in the bag, make the interior mortar of capsule bag obtain even filling, guarantee capsule bag and pipeline section closely connected joining of bottom.The technical solution of the utility model is achieved in that mainly and comprises: Grouting Pipe, the cross baffle plate, exhaust branch pipe, exhaust main, the capsule bag, the annular keeper plate of steel, the ring-shaped rubber seal plate, the steel cage plate, the steel skirtboard, bolt washer, its connected mode is: Grouting Pipe, exhaust main electricity consumption solid welding fixes on the center design attitude of steel cage plate, in the bottom of Grouting Pipe the cross baffle plate is set, exhaust main is fixed together at the bottom and the exhaust branch pipe that are connected with the steel cage plate, exhaust branch pipe is 120 ° of steel pipes by three and forms, exhaust branch pipe is close to the steel cage plate, and mouth of pipe direction in the bag has 30 ° of grooves.In steel cage plate bottom belt keeper plate of steel is set, is respectively equipped with ring-shaped rubber seal plate, capsule bag, steel skirtboard and annular pressing plate, after the usefulness bolt washer is fixedly connected, be made into the capsule bag of energy filling mortar on steel cage plate top.
On steel cage plate and steel skirtboard, weld dowel, weld together with pipeline section base plate reinforcing bar again, after vacuumizing in the capsule bag, the capsule bag is adsorbed under the base plate, and flat with the base plate face, fix with the case and bag band at last.
Foundation trench dredge dig finish with pile foundation construction waterborne after, carry out pile sinking inspection of quality, stake position and stake top mark high measurement, under water revise a stake top mark height, finally confirm the pipeline section sinking.
After the pipeline section sinking is in place, is positioned at the vertical jack in free end position with two and regulates the pipeline section position and carry out the capsule bag again and be pressed into mortar construction.At first open the steam vent valve, under effect of water pressure, empty G﹠W in the bag is discharged outside the bag, and valve-off connects Grouting Pipe and grouting pump then, when the mud jacking amount reaches, at the inferior air valve of opening, treat that pore is emerged to close the method for holding one's breath and slurry valve after the underflow, treat that at last slurries condense after, flange, ball valve are removed, and grouting port and exhaust opening are sealed with steel plate.
It is gentle that the utility model has been realized pile foundation capsule bag limit pressure injection mortar, water unnecessary in the bag is discharged on the limit, solved the problem that capsule bag slip casting can not be got rid of water and air unnecessary in the bag, make the mortar of pressure injection in the capsule bag even, full and closely knit, mortar can be filled with the capsule bag fully, avoid or reduced to form the closely connected of pipeline section and pile foundation capsule bag, satisfy the designing requirement of pile foundation by power transmission of capsule bag and pipeline section bottom close proximity because of staying bigger space after the mortar contraction.
