The temporary building supporting foundation provided by the embodiment of the disclosure can be used for supporting a main transformer overhaul room in a transformer substation in the maintenance process.
The main transformer overhaul room is mainly used for main transformer fault phase overhaul in an extra-high voltage (for example, 1000 kilovolts) transformer substation. The main transformer maintenance workshop belongs to interim building, and during the transformer substation operation, after the maintenance work was accomplished in main transformer maintenance workshop, can demolish main transformer maintenance workshop, only remain the support basis between main transformer maintenance, the support basis between main transformer maintenance is interim building support basis promptly.
The transformer substation is compact in layout, limited in land, low in use probability between main transformer overhauls, and the land that the support foundation between main transformer overhauls occupies for a long time can not regard as other usage during the transformer substation operation, causes the land waste.
For example, taking a domestic extra-high voltage transformer substation as an example, a supporting foundation of a main transformer overhaul room is 15 centimeters (cm) higher than a surrounding site, and bolts are 70cm higher than the ground. Building floor area 503.54m after main transformer overhaul room is built2The bolt enclosure is the area not available to it, i.e. the permanent footprint is 20.16 square meters (m)2) And calculating the permanent occupancy rate of the overground space of the overhaul room to be 4.0 percent. And the bolts are arranged around the edge of the supporting base, the operability of the middle part of the supporting base of the main transformer overhaul room is not large, and the middle part is particularly difficult to be used for vehicle passing, so the actual permanent space occupancy rate is between 4.0 and 100 percent.
The temporary building supporting foundation provided by the embodiment of the disclosure enables the permanent occupancy rate of the supporting foundation between the main transformer overhaul rooms to be zero, and completely releases the overground space, so that the temporary building supporting foundation can meet the needs of the main transformer overhaul and the needs of production and life at ordinary times.
As shown in fig. 1, the first surface is rectangular, and the groove 101 is disposed along the edge W of the first surface, that is, the column foot of the temporary building is connected to the temporary building supporting base along four sides of the temporary building supporting base. So that the recess 101 does not need to be disposed in the middle portion of the concrete structure 10 and the surface of the middle portion of the concrete structure 10 is flush with the ground.
In the disclosed embodiment, the groove 101 may also be referred to as a cup rim.
Referring again to fig. 1, the grooves 101 include a plurality of first sub-grooves 111 and a plurality of second sub-grooves 112 distributed on the first surface W. The plurality of first sub-grooves 111 are distributed on the first surface W. A second sub-groove 112 is disposed in one first sub-groove 111, and one first sub-groove 111 and one second sub-groove 112 form one step 113. Wherein the bolt 20 is located in the second sub-groove 112, and the removable cover 30 is located on the step 113.
In one implementation of the embodiment of the present disclosure, the openings of the first sub-groove 111 and the second sub-groove 112 are both rectangular.
In this implementation, the first sub-groove 111 and the second sub-groove 112 are both rectangular grooves, which facilitates manufacturing and arrangement of the removable cover 30.
In this implementation, the groove 101 is arranged as a stepped groove, the second sub-groove 112 is used for arranging the bolt 20, and the step 113 formed by the first sub-groove 111 and the second sub-groove 112 is used for placing the movable cover plate 30, which is more convenient.
As shown in fig. 2, six grooves 101 are disposed on both upper and lower sides of the first surface W of the concrete structure 10, one groove 101 is disposed on the left side, and two grooves 101 are disposed on the right side. In other implementations, other numbers of grooves 101 may be arranged according to the parameters of the actual temporary building, which is not limited by the present disclosure.
As shown in fig. 2, a plurality of bolts 20 are disposed in one second sub-groove 112, and the plurality of bolts 20 form a bolt group.
In the embodiment of the present disclosure, to place the bolt group in the second sub-groove 112, the area of the opening of one second sub-groove 112 needs to be at least 1m2. Meanwhile, the column base is required to be installed in the cup opening, and the size of the cup opening is required to be larger in order to meet the requirement that enough space is available for operation when the column base is installed. However, the large size of the cup rim can affect the sealing performance of the cup rim and also increase the overall cost of temporary building supporting foundation engineering, so the design of the cup rim size is important.
In the embodiment of the disclosure, the size of the cup mouth is determined according to the parameters such as the size, the weight and the shape of the temporary building and the parameters such as the size of the column base from the aspects of design and construction requirements, regulation and specification and the like.
For the above-mentioned internal extra-high voltage transformer substation, the main parameter of overhauing is certain, can go to determine that the length of rim of a cup is 1300 millimeters (mm), and the width of rim of a cup is 1600 millimeters, and the degree of depth that determines the rim of a cup simultaneously according to the size of column base is 700 millimeters. The size has universality and is suitable for the installation requirements of main transformer overhaul rooms of most of the existing domestic extra-high voltage stations.
In this disclosed embodiment, in order to make full use of above-ground space, fall interim building support basis top surface to flush with ground around to set up recess 101 at interim building support basis top surface, make recess 101 easy ponding, ponding can lead to recess 101 inner wall frost heaving destruction when the temperature is less than 0 degree, and ponding still can lead to bolt 20 to corrode, influences the use of interim building support basis.
Referring again to fig. 2, the second sub-groove 112 is filled with the sand 40, and the other end of the bolt 20 is located in the sand 40.
In the embodiment of the present disclosure, the sand 40 is disposed in the second sub-groove 112, and the amount of water flowing into the second sub-groove 112 is limited by adopting a water blocking manner, so as to reduce the possibility of frost heaving damage to the inner wall of the groove 101 and corrosion of the bolt 20.
In the related art, a drainage hole is formed in the concrete structure 10, and the water plugging method provided by the present disclosure is simpler than a manufacturing process of forming a drainage hole in the related art.
The reason why the sandy soil is selected for filling after analyzing four types of soil, namely broken stones, pebbles, sandy soil and silt, is as follows: the broken stones easily impact the bolts due to more edges and corners; the pebble void ratio is about 25 percent, the compactness is poor, and the price is expensive; the silt particles are too fine, dust is easy to generate, and the silt is easy to form when meeting water, so that the silt is inconvenient to fill and clean; it is more suitable to use sandy soil with uniform thickness as the filler.
In one implementation of the disclosed embodiment, the surface of the bolt 20 is covered with a protective film. The bolt 20 is wrapped by the protective film, reducing the possibility of corrosion of the bolt 20.
Illustratively, the protective film may be a plastic film or a zinc-plated film. The plastic film and the galvanized film have good laminating performance with the bolt, so that the sandy soil 40 can be tightly filled without leaving a gap, and a better water blocking effect is achieved.
In the disclosed embodiment, the bolts 20 are anchor bolts. The anchor bolt has a high strength, and the strength of the bolt 20 is ensured.
When the bolt is configured, the embodiment of the disclosure adopts a scheme of reversely configuring the bolt:
the bolt scheme is determined in advance by design, then the bolt scheme is provided for manufacturers, and meanwhile, each manufacturer takes corresponding structural measures to meet the stress and installation mode of the column base during structural design, so that the bolt is consistent with the interfaces of each manufacturer. The foundation bolt of the scheme can be adopted in the initial design stage, the manufacturer who waits for the design stage of the construction drawing does not need to carry out capital improvement, and the scheme of each stage of the engineering is convenient to make. Compared with the aspect of bolt stress, according to the handbook of design of steel structure nodes, the stress margin R of the bolt is between 15 and 20 percent.
For the domestic extra-high voltage transformer substation, a bolt configuration scheme of each column base is preliminarily estimated and determined according to the general design size of a main transformer overhaul room building of a national grid company, and the final bolt configuration scheme is determined as follows:
the diameter of the bolt is 40 mm (M40); the number of bolts in one cup mouth is 10; the length of the embedded bolt in the cup bottom is 1800 mm; the length of the bolt exposed out of the cup bottom is 500 mm.
The configuration scheme has universality and is suitable for structural stress requirements of main transformer overhaul rooms of most of the existing domestic extra-high voltage stations.
Referring again to fig. 2, the temporary building support foundation further includes a corner protector 50, the corner protector 50 being located between the removable cover 30 and the concrete structure 10, the corner protector 50 being disposed along an edge of the groove 101, a surface of the corner protector 50 being flush with the ground.
In the embodiment of the present disclosure, the movable cover plate 30 is installed in an embedded manner, and the notch surface is easily collided with when the movable cover plate 30 is opened or closed, so that the notch surface is damaged, and therefore, the anti-collision angle bead 50 is embedded in the notch surface, so that the collision of the movable cover plate 30 on the concrete structure 10 can be reduced.
In the disclosed embodiment, the corner protectors 50 are arranged along four edges of the first sub-groove 111.
Fig. 3 is a schematic structural diagram of a corner protector provided in an embodiment of the present disclosure. Referring to fig. 3, the corner protector 50 includes a first side 501 and a second side 502.
The first side 501 is located between the removable cover 30 and the side wall of the recess 101; the second side 502 is perpendicular to the first side 501, the second side 502 is located on the concrete structure 10, and the surface of the second side 502 is flush with the ground.
In this implementation, the corner protector 50 is arranged as two mutually perpendicular sides, and the shape of the corner protector 50 is matched with the edge of the first sub-groove 111, so that the corner protector 50 is convenient to arrange.
As shown in fig. 3, the first side 501 is located between the movable cover 30 and the sidewall of the first sub-groove 111.
Referring again to fig. 3, the corner protectors 50 also include reinforcing steel 503. One end of the reinforcing bar 503 is connected to a junction of the first side 501 and the second side 502, and the other end of the reinforcing bar 503 is positioned within the concrete structure 10.
In this implementation, the reinforcement 503 is disposed on the corner protector 50, and the other end of the reinforcement 503 is located within the concrete structure 10, ensuring the stability of the corner protector 50.
For the domestic extra-high voltage transformer substation, the angle guard 50 can be L50 × 5 equal-edge angle steel, that is, the thickness of the angle steel is 5 mm, and the length of the angle steel is 50 mm. And meanwhile, the inside of the angle steel is welded with an anchoring steel bar with the diameter of 10 mm and the length of 450 mm, and the anchoring steel bar is anchored with concrete.
Fig. 4 is a top view of a removable cover covering a recess provided by an embodiment of the present disclosure. Referring to fig. 4, the movable cover 30 includes a plurality of sub-movable covers 301, a step 113 is covered with the plurality of sub-movable covers 301, the plurality of sub-movable covers 301 are arranged in a row, and the sub-movable covers 301 are sequentially arranged along the length direction of the second sub-groove 112.
In the embodiment of the present disclosure, the opening area of one groove is large, and if one step 113 is covered with one removable cover, the weight of the removable cover is too large to be easily carried. The movable cover plate 30 is divided into a plurality of sub-movable cover plates 301, so that the weight of the sub-movable cover plates 301 can be reduced, and the carrying is convenient.
Illustratively, the width of the sub-flap 301 is 500 mm.
In the disclosed embodiment, the thickness of the removable cover 30 is between 100 mm and 200 mm. The strength of the removable cover 30 is ensured.
The quality of the deck 30 is required to meet driving requirements as it may be necessary to allow vehicles and the like to pass through the deck 30. For the domestic extra-high voltage transformer substation, the in-station road design load of the extra-high voltage transformer substation is highway-II level, and the maximum wheel pressure which can be borne by the movable cover plate 30 is more than 65 kilonewtons (kN).
Currently, common cover plates include smc (sheet Molding compound) composite cover plates, steel cover plates and reinforced concrete cover plates. The SMC composite cover plate has a plurality of advantages, but has lower bearing capacity, is generally used when the top surface of an outdoor channel is higher than a place, and is not suitable for directly bearing the load of an automobile. The steel cover plate and the concrete cover plate can meet the heavy load requirement on the ground through structural measures, but the steel cover plate is poor in overall stability, easy to deform after being stressed and not suitable for sealing the cup opening on the square ground. The concrete cover plate has good heavy load bearing performance and low price, and the concrete cover plate can achieve the effect of consistent color and luster with the surrounding ground because the ground around the cup opening is the concrete hardened square ground, so the concrete cover plate can be selected as the material of the movable cover plate 30.
For the domestic extra-high voltage transformer substation, according to design atlas of trench and cover plate, building structure load standard, concrete structure design standard, factory and mine road design standard and the like, live loads of 20 kilonewtons per square meter (kN/m) are uniformly distributed on the ground according to design of an openable movable cover plate without covering soil2) The automobile load grade is automobile-20 grade, the ground is uniformly distributed with live loads which are not combined with the automobile load at the same time, according to the design of a larger value of the automobile load grade and the automobile load grade, C30 concrete and HRB400 stress steel bars are adopted, the thickness of the movable cover plate is finally calculated to be 150mm, and the bearable wheel pressure N is 73.48 kN.
The beneficial effect of the temporary building supporting foundation that this disclosed embodiment provided includes at least:
1) the top surface of the temporary building supporting foundation sinks below the surrounding designed ground, and an openable bearing movable cover plate is covered on the temporary building supporting foundation and is integrated with the surrounding ground. The ground that becomes the support basis top of transformer overhaul room is released completely, flushes with square ground around, can reach the same service function with ground around, uses as the station front area square during the transformer substation operation promptly for the most important building the place ahead of total station has formed the square of large tracts of land, makes things convenient for the operation and maintenance personnel to use, is convenient for operation and maintenance vehicle, fire engine etc. moreover as the place of driving a car and driving passageway.
2) The foundation bolts are sunk and hidden in the temporary building supporting base cup openings, and are exposed when in use and hidden when not in use. The shortcoming that the conventional foundation bolt temporary building supporting foundation is exposed out of the ground to affect the use of a field is overcome.
3) The size of the cup mouth is determined after the cup mouth is designed, calculated and researched by a main transformer overhaul manufacturer, and the cup mouth has universality for the main transformer overhaul rooms of most of domestic extra-high voltage stations.
4) The sand is filled in the cup mouth, so that the problems of frost heaving damage and bolt corrosion caused by accumulated water in the cup mouth are prevented, and the filling material can be repeatedly utilized before and after the main transformer is overhauled.
5) The foundation bolt is prevented from being corroded and is wrapped by hot galvanizing and a plastic film, so that the bolt is effectively protected.
The disclosed embodiments provide a temporary building support foundation that is exposed when in use and hidden when not in use. And water blocking measures are adopted in the cup openings to replace drainage measures. The foundation bolt is protected by being wrapped by a protective film for corrosion prevention.
For the transformer substation, the permanent occupancy rate of the temporary building support foundation is reduced to 0, and the temporary building support foundation is arranged in a pre-station area and used as a square, so that the land acquisition area of a power distribution device area is reduced, and the land acquisition cost is saved. The basic farmland or the general farmland is the key national protection land, the construction land is scarce at present, the site selection of a transformer substation is difficult, the land utilization area is reduced by the technology, and the social benefit is remarkable. The foundation bolts sink and are hidden underground, so that the stress safety of the bolts is prevented from being influenced by vehicle collision during the operation of the transformer substation; the personal injury caused by the fact that personnel touch the bolt is avoided.
The above description is intended to be exemplary only and not to limit the present disclosure, and any modification, equivalent replacement, or improvement made without departing from the spirit and scope of the present disclosure is to be considered as the same as the present disclosure.
