Specific embodiment
As shown in figures 1 to 6, the blower fan outer platform is socketed on single-pile foundation the present invention, and the blower fan outer platform includes this
Body, some concentric collar tie beams and an at least cable channel, the collar tie beam are fixedly connected in body and single pile base described in empty set
Plinth;
Poor for connective stability difference and capacity of anti-storm, following improvement has been made in this case:
The cable channel 7 is fixedly linked with some collar tie beams 3, and the cable channel 7 includes n straight tube 71 and n-1 connection
Pipe 72, n is the integer more than 1, all straight tubes 71 and the concentric setting of connecting tube 72, is had between the adjacent straight tube 71
There is space, the connecting tube 72 is located in space and its head and the tail two ends is fixedly linked with two straight tubes 71 respectively, the connecting tube 72
It is bellows expansion joint, the straight tube 71 or connecting tube 72 are fixedly connected with collar tie beam 3.So, due to cable channel and collar tie beam it
Between relative motion it is actual be along the axial motion of cable channel, therefore, after cable channel bears stormy waves, can by connection
The elastic deformation of pipe carries out the nose balance of allowed band to the relative displacement between straight tube and collar tie beam, so as to elastic deformation
Mode causes that relative displacement can be done between cable channel and collar tie beam in certain allowed band, and causes the displacement to cable tube
Connective stability between road and collar tie beam is not impacted.Have that structural stability is high, bonding strength is high and suitable on the whole
Answer the characteristics of stormy waves ability is strong, and the protecting effect to cable is good.
For installation difficulty is big, connection precision is low, following improvement has been made in this case:
The outer platform also includes and the one-to-one some mounting rings 4 of some collar tie beams 3 and some groups of fixed blocks 5, same group of institute
State fixed block 5 highly consistent and be fixedly connected with the outer wall of single-pile foundation 1, fixed block 5 described in same group is located at a collar tie beam
Within the 3 and bottom of the collar tie beam 3 is fixedly connected with spacing ring 31 for propping up the fixed block 5;The mounting ring 4 is wrapped
The substrate 41 and some inserted blocks 42 of annular are included, if the substrate 41 is fixedly linked by bolt stem 410 with the top surface of collar tie beam 3, if
The dry inserted block 42 is fixedly connected with the bottom surface of substrate 41 and inserts between the fixed block 5 and collar tie beam 3.So, complete
Into after fixed block, the installation of limiting plate, can be on from lower loading mounting ring so that some inserted blocks insertion fixed blocks and collar tie beam it
Between, so that keeping closely connection between single-pile foundation, fixed block, inserted block, collar tie beam, and then ensure collar tie beam and single pile base
The concentric of height is kept between plinth.Hereafter, the assembling of some mounting rings is completed one by one, so that can be by single-pile foundation and institute
The concentric self structure intensity to outer platform for having collar tie beam brings and is significantly lifted, and between outer platform and single-pile foundation
The significantly lifting that also brings of bonding strength.
It is fixedly linked and is interconnected by adpting flange 73 between the straight tube 71 and connecting tube 72.So, can be one by one
Straight tube, connecting tube are installed, installation difficulty that traditional cable protection pipe occurs because oversized is significantly reduced big etc.
Problem.
The outside of the collar tie beam 3 is fixedly connected with connecting seat 32, and the cable channel 7 is consolidated by connecting seat 32 with collar tie beam 3
It is fixed to be connected.
The inserted block 42 small big ladder shaft-like and is provided with the mistake of conical surface shape under being between the big axle and small axle of multi-diameter shaft
Degree face 420.So, can be positioned by the small axle of multi-diameter shaft during installation, and may be such that after mounting the big axle of multi-diameter shaft with
Gap between fixed block, collar tie beam is in interference fit state.
The fixed block 5 dorsad offers the slot 1 being adapted to inserted block 42, the collar tie beam on the end face of single-pile foundation 1
Some slots 2 30 being adapted to inserted block 42 are offered on 3 inwall.So as to good by slot one, slot two at the initial stage of installation
Good, stabilization guide effect so that the loading of mounting ring can be more quick and easy, brings to the overall installation period of outer platform
Significantly reduce.
The substrate 41 of the mounting ring 4 is made up of half circular substrate of two halves, and half substrate is removably connected described in two
Connect.So as to reduce installation difficulty, the effect for significantly improving is served to installation effectiveness.
The top of the bolt 410 is fixedly connected with drive gear, the single-pile foundation 1 is outer be also set with a pair it is detachable
Connected driving semi-ring 6, the inwall for driving semi-ring 6 is provided with the internal tooth engaged with the drive gear.When using, right
If the initial stage of bolt stem fastening, the driving semi-ring after rotating two connections can be first passed through so that all bolts in same mounting ring
Backspin and tighten simultaneously, when there is larger screwing force on bolt, then by manually being entered to bolt by instruments such as torque spanners
Row is tightened one by one, and causes that the screwing force on all bolts is consistent.So, may be such that all inserted blocks in same mounting ring first
Phase can carry out insertion simultaneously, cause what opposite side inserted block cannot insert to ask because side inserted block is first inserted so as to effectively prevent
Topic.
Installed according to the following steps:Single-pile foundation in this case is by steel cylinder and its interior coagulation local soil type into therefore herein
It should be noted that the single-pile foundation mentioned in following installation processes is steel cylinder;
1), install fixed block:
1.1), single-pile foundation is lifted to vertical state;
1.2), on the outer wall of single-pile foundation draw datum line;
1.3), first fixed block sling to vertical state, then will be on fixed outer wall of the block welding with single-pile foundation by datum line;By
Be much smaller than single-pile foundation in the volume of fixed block, therefore, be only completed therebetween to be fixedly connected the connection that can keep higher strong
Degree and preferably quality of fit;
2), place single-pile foundation:The single-pile foundation that fixed block will be connected with is put into outer platform;So that collar tie beam empty set single pile base
Plinth and some groups of fixed blocks be placed in within each self-corresponding some collar tie beams;
3), set spacing ring:Some spacing rings are fitted in one by one on the bottom surface of some collar tie beams, and complete the spacing ring with circle
Being fixedly connected between beam;So as to provide a further support force to fixed block;
4), set mounting ring:Being fixedly connected between two two halves substrates is completed one by one, and is caused single described in some mounting ring empty sets
Pile foundation;Now, the inserted block below mounting ring will be set towards the gap between fixed block and collar tie beam;
5), fasten mounting ring one by one:
5.1), inserted block is directed at the gap of fixed block and collar tie beam, and by between the bottom insertion fixed block and collar tie beam of inserted block;Now
A small amount of loosening will be still kept between three;
5.2), be put into bolt, and complete to drive two-by-two being detachably connected between semi-ring;
5.3), first turn drive semi-ring to cause bolt backspin one end distance, driving semi-ring is being unloaded, by manually tightening bolt and school
Core screwing force;Finish.So that the big axle in inserted block gradually will be pressed into fixed between block and collar tie beam, and be in therebetween
Interference fit state so that closely connection is kept between single-pile foundation, fixed block, inserted block, collar tie beam, to ensure collar tie beam and list
The concentric of height is kept between pile foundation.
