Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the patent easy to understand, the patent is further described below by combining the specific drawings.
As can be seen from fig. 1, the assembly-type foundation ground fixing member 1 is composed of a rigid bag 11, a reinforced band 12, a hanging band 13, a sealing cloth 14, a sealing adhesive strip base surface 15, a sealing adhesive strip adhesive surface 16, an interconnecting ring 17, an interconnecting ring connecting member 18, a filler 2, a bottom tapered groove 21, an embedded connecting seat 3 and the like. The adjacent ground fixing members 1 are assembled into a whole by the interconnecting ring 17 and the interconnecting connector 18, as shown in fig. 2 and 3. The pre-buried connecting base 3 is composed of a bottom plate 31 of the connecting base, a connecting rod 32, a connecting screw hole 33, a connecting bolt 34 and the like, as shown in fig. 4.
The foundation or foundation with different functions is assembled by the ground firmware 1, so that higher vertical and horizontal bearing capacity can be obtained in time, the construction time of engineering is shortened, the requirement on traditional building materials is reduced, the utilization value of waste muck and field soil is fully exerted, and the purposes and social significance of the ground firmware assembly type foundation and foundation are explained through a plurality of specific cases.
Example one, the ground firmware is assembled to form the foundation of a temporary road or yard.
The traditional method is to solidify or replace the soft sludge, tamp the soft sludge layer by layer to form the foundation, and then pour the concrete pavement or the terrace, which needs to occupy a longer construction preparation period.
Fig. 5 is a schematic view showing a temporary road and a site base formed by assembling the single-layer ground fixing 1. The method comprises the following steps of (1) paving a ground firmware 1 on a soft foundation 5; assembling the adjacent ground fixing members 1 into a whole by the interconnecting ring 17 and the interconnecting connecting member 18; by using the tapered groove 21 formed at the bottom of the ground fixing member 1, a protruding tapered soil body 53 can be formed on the weak foundation 5 by paving and pressurizing, so that the horizontal frictional resistance between the ground fixing member 1 and the foundation 5 is increased greatly. Due to the hydrophobic nature of the ground fastener 1, the vibration pressure can quickly form a crust layer in the foundation 5 below the ground fastener 1.
After the ground fixing member 1 is laid, when the surface is still uneven after the flat plate is vibrated, the ground fixing member 1 is leveled by sand to form a leveling layer 54, and then the protective layer 61 is covered on the ground fixing member 1, so that a complete temporary road or temporary field can be formed, and the ground floor can be used as a foundation floor of a construction activity or a parking lot, or a construction office and living room. When plastic plates or waste conveyor belts are used as the protective layer 61, the protective layer can be connected with the embedded installation seats 3 of the ground fixing pieces 1.
Fig. 6 is a schematic view showing a temporary road and a site base formed by assembling a plurality of layers of the ground fixing members 1. Such roads or sites are often used when the foundation is very weak or is subjected to very high loads. The upper and lower floor fixing members 1 are connected with each other by an interconnecting ring 17 and an interconnecting connecting member 18 to form a whole. The lower layer of the ground fixing member 1 can be laid densely or in a grid shape, but gravel or sandy soil is used for filling in the open position, and a layer of geotextile 4 is laid on the contact surface of the ground fixing member 1 and the soft stratum to enhance the integrity of the combination of the ground fixing member 1 and the foundation 5, so that the temporary road and the field which are manufactured in this way can be used as soon as the temporary road and the field are laid without maintenance.
Example two, the assembly of the ground firmware forms the foundation of a permanent road or yard.
In order to reduce the influence of vibration and earthquake generated during the use of the road or the field on adjacent buildings and structures, the ground firmware 1 can be adopted for assembly to form a foundation of a permanent road or field.
As shown in fig. 7 and 8, the ground fixing member 1 is laid on the compacted foundation 5 to replace a water-stable layer or a mattress layer; assembling the adjacent ground fixing members 1 into a whole by the interconnecting ring 17 and the interconnecting connecting member 18; by using the conical groove 21 formed at the bottom of the ground fixing member 1, a protruding conical soil body 53 can be formed on the weak foundation 5 by paving and pressurizing, so that the combination between the ground fixing member 1 and the foundation 5 is tighter.
After the ground fixing member 1 is laid, when the surface is still uneven after the flat plate is vibrated, the ground fixing member 1 is leveled by sand to form a leveling layer 54, and then the pavement layer or the terrace layer 6 is covered on the ground fixing member 1, so that a complete road or field can be formed.
Fig. 8 is a schematic view showing a road and a field foundation formed by assembling the multi-layered flooring member 1. Such roads or sites are often used when the foundation is weak or is subjected to high loads. The upper and lower floor fixing members 1 are connected with each other by an interconnecting ring 17 and an interconnecting connecting member 18 to form a whole. The lower layer of ground fixing member 1 can be laid densely or in a grid shape, but gravel or sand is filled in the open space, and a layer of geotextile 4 should be laid on the contact surface with the weak ground layer to enhance the integrity of the ground fixing member 1 and the foundation 5. The road and the field manufactured in the way do not need maintenance, can be used after being paved, and can simultaneously reduce the influence of traffic load vibration and earthquake on nearby buildings and structures.
And in the third instance, the ground firmware is assembled to form a ground structure foundation.
In the construction of new foundation, structures such as power transmission towers, photovoltaic panel supports, vertical poles and the like need to be arranged in areas with inconvenient traffic, and traditional foundation base materials such as concrete materials or prefabricated parts are difficult to transport, so that the foundation needs to be made of on-site materials to fix the structures.
Fig. 9, 10 and 11 show an iron tower, a photovoltaic plate foundation and a vertical rod foundation when cables and communication equipment are erected in mountainous, desert or beach areas, etc., it can be seen from the figures that a groove is dug at the position where such structures need to be erected, the size of the base groove is determined according to the bearing capacity (horizontal and vertical) required by the stable erection of the structures, then the rigid bag 11 of the ground fixing member 1, including the reinforcing band 12, the hanging strip 13, the sealing cloth 14, the sealing adhesive strip base surface 15, the sealing adhesive strip adhesive surface 16, the interconnecting ring 17 and the pre-buried connecting seat 3, are placed into the base groove, the grooved sandy soil is used as the filler 2 to fill the rigid bag 11, the bag is sealed after being vibrated and compacted, and the adjacent ground fixing members 1 are assembled into a whole through the interconnecting ring 17 and the interconnecting connecting part 18. Then the pre-buried connecting seat 3, the iron tower 73, the photovoltaic plate 74 and the base of the upright post 75 are fixed with the connecting bolt 34, and then the outer side of the ground fixing member 1 is covered with a ground fixing member protective layer 61, wherein the protective layer can be a layer of soil or a layer of plastic plate and the like.
Example four, the assembly of the ground fasteners forms the pool, piping and multi-storey building foundations.
Multi-storey buildings with ponds, pipes and brick-and-concrete structures, which are more stringent for differential settlement control, require a better flexible foundation to withstand the overlying loads, which is the performance of the fabricated foundation.
Fig. 12 and 13 are schematic sectional views showing a foundation of a pool, pipes and a multi-storey building, in which a ground fixing member 1 is laid under a multi-storey building 7 and a pool or ditch 71, and a filler 2 tightly wrapped by a rigid bag 11 of the ground fixing member 1 has a flexible shape-preserving effect, absorbs part of wave energy transmitted from the outside of the foundation 5, and keeps the shape of the foundation unchanged, thereby reducing differential settlement of the foundation.
Example five, a hard shell foundation was assembled with ground fasteners on a blow-fill formation.
In order to protect agricultural cultivated land, industrial and traffic and real estate development land is mostly filled with mud from mud flat, a soft foundation with ultrahigh water content is formed, the soft foundation treatment method is vacuum preloading or mound preloading, the cost is high, and the required time is long, therefore, a hard shell layer with a certain thickness is formed by adopting a ground firmware 1, the requirements of foundation bearing capacity and post-construction settlement control can be met, related construction operation can be carried out in time, and the waiting time for foundation treatment is shortened.
Fig. 14 is a schematic cross-sectional view of a hard-shell foundation formed by reinforcing a region where a large amount of earth is piled on a soft layer to reach the standard height of the foundation with a ground fixing member 1, and it can be seen from the figure that the ground fixing member 1 is directly laid on a soft foundation 5, so that the ground fixing member 1 can be filled with earth 51 in layers and compacted in layers, so that a foundation with a certain thickness can be formed, and the requirements of construction activities, factory building and multi-layer office building on the foundation can be met. If the earth 51 is directly filled without laying ground firmware, the goal of layered earth fill compaction cannot be achieved. Such treatment also reduces the amount of fill required to be increased by settling caused by consolidation of the drainage, and also reduces further settling caused by increased loading of the fill thickness.
According to the design elevation requirement, when the thickness of the required filling soil is small, a foundation with a certain thickness is formed by draining and consolidating the weak stratum, and then the foundation is compounded with the ground firmware 1 and the mound to form a hard shell layer foundation 5, as shown in fig. 15. It is required to insert a short drainage plate 41 (generally less than 5 m) into a weak stratum to realize rapid and efficient drainage consolidation, then lay a layer of ground fixing pieces 1, fill soil on the ground fixing pieces, and laminate and roll the ground fixing pieces. Therefore, a large amount of construction period can be saved, and the work load of filling soil is reduced.
Sixth example, the reinforced foundation of the large-scale wind power is formed by assembling ground firmware
The offshore wind power facility adopts a steel pipe pile foundation, and generally adopts a rock-entering-free mode due to the large rock-entering difficulty of inserting the steel pipe pile foundation into a seabed. In addition, the scouring of ocean currents and the swing of wind power operation enable the depth of an original pile foundation embedded into a seabed to be continuously reduced, threat is formed to the safety of the pile foundation, and therefore the foundation of the wind power pile foundation needs to be reinforced.
Fig. 16 is a schematic cross-sectional view of a wind power foundation structure 72 reinforced by ground fasteners, and it can be seen from the figure that the ground fasteners 1 with better durability are combined to form a larger and stable retaining wall structure, and surround the wind power upright posts and the foundation 72 to form a complete structure, which can quickly play a role of reinforcement.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
