Abstract
The invention relates to the field of building construction, in particular to a reinforcement cage feeding method of a long auger drilling press-grouting pile. The reinforcement cage feeding method of the long auger drilling press-grouting pile is characterized by comprising the following steps that 1, a pushing device is manufactured according to hole diameters, and the pushing device comprises a plurality of vertical rods and a plurality of hoops which surround the vertical rods to form cage-shaped columns; 2, concrete is poured into a pile hole to reach a standard height; 3, a reinforcement cage is inserted into the pile hole; 4, the cage-shaped columns are lifted, and the bottoms of the cage-shaped columns align to and abut against the tail end of the reinforcement cage; 5, a vibrating tamper is started to convey the reinforcement cage to the designed standard height position of a pile bottom through the cage-shaped columns; and 6, the device and the vibrating tamper are together lifted out of the pile hole. According to the reinforcement cage feeding method, the adopted cage-shaped columns are easy to manufacture and convenient to use so as to effectively accelerate the feeding operation of the reinforcement cage, and the cage-shaped columns can be recycled and reused, so that the cost of construction operation is lowered, and the operation efficiency is improved.
Description
Technical field
The present invention relates to the realm of building construction, specifically a kind of reinforcing cage feeding method of long auger guncreting pile.
Background technology
Long auger guncreting pile construction technology first utilizes drill hole of drilling machine, holes to projected depth, while carry brill, while pump into concrete, finally sends into reinforcing cage again.Construction like this, because hole rough inner surface is uneven, and is injected with concrete, causes the reinforcing cage of same rough surface injustice be easily stuck in feeding process or cannot carry arrival predeterminated position.
Summary of the invention
The object of the invention is to, a kind of feeding method enabling reinforcing cage be sent to predeterminated position accurately, is quickly and easily provided.
In order to achieve the above object, the present invention is achieved in that
A reinforcing cage feeding method for long auger guncreting pile, comprises the steps:
Step 1, make thrustor according to aperture, described thrustor comprises montant and anchor ear, and montant has many in vertically arranging, and montant surrounds and forms cage type post by anchor ear;
Step 2, in stake holes, inject concrete to absolute altitude,
Step 3, by reinforcing bar cage hoisting to stake holes top, and insert reinforcing cage in stake holes, now reinforcing cage end is exposed to outside stake holes;
Step 4, the cage type post in this step 1 to be sling, its bottom alignment is propped up reinforcing cage end,
Step 5, again vibrator to be enclosed within cage type post, then to start vibrator, by cage type post, reinforcing cage is delivered to absolute altitude at the bottom of design stake;
Step 6, then utilize rig that this device is hung out stake holes together with vibrator.
The cage type column production that this pile follower method adopts is simple, easy to use, effectively can accelerate the feeding operation of reinforcing cage and cage type post itself can be recovered and reuse, and then reduces construction operation cost and improve operating efficiency.

Fig. 1 is this construction method schematic diagram one.
Fig. 2 is this construction method schematic diagram two.
Fig. 3 is this construction method schematic diagram three.
Fig. 4 is this construction method schematic diagram four.
Detailed description of the invention
The present invention is further illustrated below by way of specific embodiment.
Certain pile foundation engineering adopts long auger guncreting pile, and natural terrace absolute altitude is-0.5m, the high-1.9m of stake top mark; Subordinate's method is used to construct:
1, leading bore operation: after subdrilling is deep to projected depth, then carry and bore 200mm, pump into concrete, then brill is carried on limit, while pump into concrete, wherein, slump must be greater than 200mm, to facilitate insertion reinforcing cage;
2, as shown in Fig. 1 ~ Fig. 4, adopt cage type post 1 to carry out reinforcing cage and send into operation, comprise the steps:
Step 1, described thrustor comprise montant and anchor ear, and montant has many in vertically arranging, and montant surrounds and forms cage type post 1 by anchor ear;
Step 2, in stake holes, inject concrete to absolute altitude,
Step 3, to lift reinforcing cage 2 to stake holes top, and insert reinforcing cage 2 in stake holes, now reinforcing cage 2 end is exposed to outside stake holes;
Step 4, the cage type post 1 in this step 1 to be sling, its bottom alignment is propped up reinforcing cage 2 end,
Step 5, again vibrator to be enclosed within cage type post 1, then to start vibrator, by cage type post 1, reinforcing cage 2 is delivered to absolute altitude at the bottom of design stake;
Step 6, then utilize rig that this device is hung out stake holes together with vibrator.
