Description
Technical field
The present invention relates to electric power foundation construction technical field more particularly to high voltage joinery and its construction assembled main transformer foundation,
Suitable for 110kV or more high voltage assembled main transformer foundation.
Background technique
Traditional 110kV main transformer foundation is cast-in-place concrete isolated footing, cast-in-place basis need live formwork, tie up muscle, pour,
Maintenance, long construction period are unsatisfactory for reorganization and expansion construction period；Different basic engineering size disunities, consumption templating species compared with
It is more, increase construction complexity；Situ wet operation, which protects ring water, to be influenced greatly.
Existing prefabricated main transformer foundation pattern is low-voltage-grade, it is difficult to applied to 110kV and the above voltage levels
In main transformer, since voltage class is higher, main transformer is heavier, and main transformer foundation size increases therewith, due to the component volume of main transformer foundation
Greatly, structure bulky, transport and construction site lifting cost are big, and especially reconstruction and extension project is limited by place, can not apply excessive ton
The crane equipment of position.
In view of the above problems, also there is fabricated main transformer foundation structure at present, but needed between each absolute construction
The connection such as bolt, causes to be not connected firmly, the non-uniform problem of bottom slab stress, and big weight is still overweight, it has not been convenient to grasp
Make, is equally dfficult to apply in the main transformer foundation of 110kV and above.
Summary of the invention
The present invention overcomes the shortcomings of the prior art, is not connected firmly for current assembled main transformer foundation, easily occurs
Unbalance stress, provides a kind of assembled main transformer foundation of high voltage joinery and its construction, the knot at the problem of cannot carrying high-voltage installation
Structure main transformer foundation reduces the weight of unit structure while reinforcing connection, is suitable for voltage levels.
The present invention is achieved through the following technical solutions.
A kind of high voltage assembled main transformer foundation, the main transformer foundation include multiple individual members, the independent structure
Part surface is provided with multiple protrusions, so that being spliced to form Tenon knot by raised top-bottom cross occlusion between each individual member
Structure；It is vertically connected and fixed between the individual member by embedded bar, the individual member is wide flat type girder construction, institute
The ratio of the width and height of stating wide flat type beam is 4-5:1；Each individual member is designed using unique wide-flat beam, common with design
Board member is compared, and width and the deformation in crack are greatly reduced.
Further, the main transformer foundation include mat foundation and be arranged on the mat foundation and and mat foundation
Mutually multiple buttresses of occlusion；The buttress is for preventing main transformer foundation lateral deformation；The mat foundation and buttress is by phase
Upper layer individual member and lower layer's individual member composition being mutually engaged, the upper layer individual member and lower layer's individual member are cross
Shape X-bite.
Further, the mat foundation lower part is provided with piece raft bottom plate, and the piece raft bottom plate is by first raft
Big plate and second big board group of raft are at being provided with reserved stealthy bolt hole, second raft on the big plate of first raft
Pre-embedded bolt corresponding with the reserved stealthy bolt hole position, the big plate of first raft and second raft are provided on big plate
Big plate is connected by tongue and groove.It is designed among two pieces big plate using tongue and groove, is connected using high strength bolt, avoid single structure
Part is settled because ground is uneven, improves the overall stability of structure.
Further, the spacing of the buttress is consistent with the transformer gauge that needs are set up.It is symmetrically set in bottom plate simultaneously
On the Vertical Compression face of concave-convex-piece, meets structure load path and define, uniform force requirement.
Further, the upper layer individual member of the mat foundation and lower layer's individual member surface are connected by steel plate weld seam
It connects.
Optimized on the basis of previous step, the steel plate be embedded in the outermost upper layer individual member in mat foundation or under
In layer individual member.The outermost member on bottom two layers of basis is by the full solder design between pre-embedded steel slab, external member
Freedom degree be almost reduced to zero, thus improve basis overall stability.
Further, the individual member includes the pouring layer on skeleton and the skeleton, and the skeleton includes
Inside and outside two layers hooping structure being nested with.Total cross-section reduces the transport proportion of goods damageds using the compound stirrup form of " the big small hoop of cuff ",
The local compression for avoiding component simultaneously destroys and occlusal surface generates stress and concentrates, while also improving the reuse of component
Rate.
Further, the individual member is internally provided with stealth and hangs nail.Table of the nail than individual member is hung in the stealth
Face is slightly lower, so that the plane in each structure does not protrude, so that the fitting of each layer is more closely.
Further, grouting hole is reserved at the individual member concave-convex clutch.Meet prefabrication requirement；Scene
Grouting material bonding meets globality requirement；Concave and convex part bottom fits like a glove, and does not interspace, it is ensured that upper and lower pieces are tightly compacted, full
Sufficient uniform force requirement.
The present invention is generated compared with the existing technology to be had the beneficial effect that
The present invention is conveniently used for transporting and lift, then be transported to construction by the way that production maintenance is completed in advance respectively to individual member
Place is combined, installs, and improves the efficiency of work on the spot, reduces working procedure, shortens the construction period, exploitativeness is strong.Same layer
And upper and lower individual member arranged crosswise, it is engaged completely using physics；The arranged crosswise of bottom plate keeps stress more evenly reasonable, bottom
The strong while less bolt of the support force of plate and buttress connects constructional difficulties.The composition of bottom plate and the composition of buttress
It is all made of concave-convex clutch, physical connection, meeting top weight of equipment can uniformly transfer by buttress to bottom plate；Meet base simultaneously
Plinth antidumping requirement；It is able to satisfy the main transformer foundation supporting requirement to 110kV and above.It is arranged in mat foundation lower part
Piece raft bottom plate, avoid single component and settled because ground is uneven, improve the overall stability of structure.It is entire main
Become structure and connection relationship of the basis by each individual member, under the premise of guaranteeing basic bearing strength and stability, weight
Amount is greatly lowered, and convenient transportation is also applied for voltage levels while installation.
