Abstract
The invention discloses a method for fixing a ground wave radar antenna mounting base on a reef base. An inner ring and an outer ring of anchor bolt via-holes are mounted on a flange plate, anchor bolts penetrate the via-holes of the flange plate to be fixed by nuts, and flat steels are welded with the anchor bolts around the circumference of the outer ring of the anchor bolts to form an anchor bolt cage. Embedded steel bars are arranged circumferentially, one end of each embedded steel bar is embedded into the reef, the other end bassets, the embedded steel bars are reinforced in a twining mode by helical reinforcement, and welding is performed at the contact points to form an embedded steel bar cage. The mounted embedded steel bar cage and the mounted anchor bolt cage are welded by transverse reinforcement. The mounting base can be stably and reliably mounted on the reef base, optimization of mounting interface form of antenna base and antenna body is realized, anti-typhoon performance of the antenna base is enhanced, service life of the antenna base is greatly prolonged, and selectivity of mounting locations is greatly increased.
Description
Technical field
The present invention relates to a kind of construction method of ground wave radar astronomical cycle pedestal, be specifically related to a kind of method of building ground wave radar astronomical cycle pedestal on reef basis.
Background technology
Radar station is generally arranged on landforms more complicated, weather conditions compare rugged environment, such as be built in the radar station on seashore, the transmitting antenna of radar station and reception antenna need to be vertically fixed on ground, therefore need to build solid and reliable mounting seat on the ground to be used for fixing up an aerial wire.
The geological foundation in coastline is reef mostly, due to the hard and profile very irregular of reef quality, be difficult to set up stable, reliable mounting base thereon, at present, avoid reef to the site-choosing principle of radar station as far as possible, but for the radar station that the necessary along the coastline of addressing is set up, it is then the technical problem that cannot avoid that reef basis is built astronomical cycle pedestal.
Summary of the invention
In view of this, the invention provides a kind of method of building ground wave radar astronomical cycle pedestal on reef basis, can realize building astronomical cycle pedestal on reef basis, and guarantee the structural strength of mounting base.
Reef basis is built a method for ground wave radar antenna mounting base, and its construction sequence is as follows:
The first step, do basis with reef reinforcing bar is vertically implanted its inside from the surface of reef, the reinforcing bar implanted circumferentially is arranged in horizontal projection direction, the length of implant part is not shorter than 10 times of bar diameter, the actual conditions such as intensity and thickness according to rock stratum should suitably lengthen, ensure that bar planting has been inserted into reliable and stable rock stratum really inner, thus strengthen its implantation intensity;
Second step, for the bar planting of inserting rock, fills out envelope bonding agent in the gap of bar planting and hole wall; Can make pull-out test to the every root reinforcing bar implanted if desired, whether the power that dynamometer applies is between the yield strength and bar planting design anchoring force value of reinforcing bar, firm for determining reinforcing bar implantation;
3rd step, after adopting spiral reinforcement to carry out circumference or spiral winding to vertical reinforcing bar, welding forms metal cage;
4th step, stone bolt is circumferentially arranged on flange and forms fastener inserts, the thread segment of stone bolt is through being fixed in flange by two nuts from two faces of flange after the via hole on flange, guarantee the surface of flange and the axes normal of stone bolt, the length that stone bolt exposes flange upper surface portion is consistent; The circumference that stone bolt is formed is concentric with metal cage;
5th step, by the flange that assembles and stone bolt by stone bolt and transverse reinforcement and metal cage welded together, the upper surface of flange should keep level as astronomical cycle face;
6th step, carries out building template at the construction field (site), then the assembly casting cement that connects of butt welding, forms the clump of lower large little side's mesa-shaped, and the upper surface of clump is lower than the upper surface of flange.
Beneficial effect:
1, the mode that the present invention adopts reinforcing bar to implant reef builds the basis of astronomical cycle pedestal, and it is integral to adopt concreting that installation foundation and reef are completely fixed, for radar antenna mounting seat provides solid and reliable mounting base.
2, the present invention can entirety be fixed on sandy soil basis, the part that stone bolt in component exposes flange becomes firmly coupling part, the mounting seat of antenna support group is fixing after himself flange and flange of the present invention just can be utilized to achieve a butt joint, and is conducive to the installation of antenna and follow-up maintenance and displacement.
3, bolt cage of the present invention can assembly welding in advance, and bar planting needs on-the-spot singlely to implant in the rock stratum of reef successively, then carries out spiral winding with reinforcing bar, and is welded to connect with bolt cage, finally concreting again.Although goods and materials are scattered like this, are convenient to goods and materials light and fast to be transported to antenna farm, saved transport and human cost;
4, bar planting of the present invention can implant the position of certain depth in rock, or expand scope and the quantity of its bar planting, simultaneously integral with the bolt cage concreting at its top, both greatly strengthen the ability of its supporting antenna body weight, also it is made to take root solid, even if typhoon arrives like this, antenna foundation also can not be made to collapse.So this antenna foundation is practically applicable to reef geological environment.

Detailed description of the invention
To develop simultaneously embodiment below in conjunction with accompanying drawing, describe the present invention.
As shown in Figure 1, the invention provides a kind of method of building ground wave radar astronomical cycle pedestal on reef basis, its construction sequence is as follows:
The first step, do with reef the reinforcing bar that 12 diameters are 16mm by basis and vertically implant its inside from the surface of reef, the degree of depth of implantation is for being not less than 200mm, and the reinforcing bar of implantation is circumferentially arranged in horizontal projection direction, circle diameter is 540mm, and the length of reinforcing steel bars exposed part is 1000mm;
Second step, for the bar planting of inserting rock, fills out envelope bonding agent in the gap of bar planting and hole wall.Make pull-out test to the every root reinforcing bar implanted, whether the power that dynamometer applies is between the yield strength and bar planting design anchoring force value of reinforcing bar, firm for determining reinforcing bar implantation;
3rd step, after adopting spiral reinforcement to carry out circumference or spiral winding to vertical reinforcing bar, welding forms metal cage;
4th step, stone bolt is circumferentially arranged on flange and forms fastener inserts, the thread segment of stone bolt is through being fixed in flange by two nuts from two faces of flange after the via hole on flange, guarantee the surface of flange and the axes normal of stone bolt, the length that stone bolt exposes flange upper surface portion is consistent; The circumference that stone bolt is formed is concentric with metal cage;
5th step, by the flange that assembles and stone bolt by stone bolt and transverse reinforcement and metal cage welded together, the upper surface of flange should keep level as astronomical cycle face;
6th step, carries out building template at the construction field (site), and the assembly that then butt welding connects waters C30 cement, form the clump of lower large little side's mesa-shaped, the height of clump is 1200mm, and base length is 1200mm, top margin length is 600mm, and the upper surface of clump is lower than the upper surface 50mm of flange.
As shown in Figure 2, when installing antenna 7, after being aimed at stone bolt exposed portion on mounting base by the installing hole on antenna base, nut is locked.
