Description
Technical Field
The invention belongs to the technical field of polluted soil restoration construction, and particularly relates to an assembled cavity cup rim foundation structure.
Background
Along with the development of industrialization and urbanization in China, the pollution to the soil environment caused by human activities is more serious. Currently, the soil pollution exceeding rate of China reaches 16.1%, and the soil pollution exceeding rate is particularly expressed in various aspects of industry, mining industry, agriculture and the like, and is mainly concentrated on the periphery of mining industry with higher modern economic development level and rapid development of modern industry, and partial cities and suburban areas.
At present, the polluted soil restoration technology mainly comprises an in-situ restoration technology and an ex-situ restoration technology, and aiming at the characteristics of short construction period, complete removal and sufficient budget of the pollution site restoration project in the current stage of China, the ex-situ restoration technology is widely applied to pollution restoration of urban brown plots and industrial mining sites. The ectopic repairing process needs to excavate, screen, stir and the like the polluted soil, but has the advantages of short repairing time, high engineering controllability, obvious effect and the like, and is relatively suitable for small-area or heavy-pollution land plots.
At present, the ex-situ remediation operation process of the polluted soil is often carried out in a closed soil remediation workshop, and most of common soil remediation workshops are steel structure tectorial membrane workshops. The repair workshop use process has the characteristics of short service cycle, high quality requirement and the like. Meanwhile, the upper structure of the steel structure film-covered workshop is lighter and greatly influenced by wind power, when the workshop is constructed, the workshop foundation needs to be considered to bear the longitudinal load of the upper structure, and the transverse stabilizing effect on the upper structure of the workshop is also considered to ensure the safe and reliable repair construction process in the workshop, so that the cost and the construction period of the whole workshop are increased, and the construction difficulty is greatly improved.
The invention of patent number CN 106192670A discloses a field foundation which comprises a first foundation module and a second foundation module. A plurality of first basic modules splice into the basis that has the radian, and a plurality of second basic modules splice into the rectangle basis, and inside fretwork of basic module just is equipped with the space that can supply the people to get into to be equipped with the drainage channel in the inboard. The foundation provided by the invention is provided with the space for overhauling staff to enter the foundation for overhauling, and has good ventilation, and the drainage channel is arranged in the foundation module, so that the drainage capacity of the foundation is improved, and the foundation has the advantages of simplicity in construction, shortened construction period, unified rebound of the foundation and the like. However, the foundation of the invention has larger volume, large excavation workload of the foundation pit in the foundation construction process and higher construction cost. In addition, the foundation is of a hollow structure, so that the bearing capacity of the foundation is greatly reduced, and the performances of the foundation, such as bearing capacity and the like, are reduced.
The invention patent No. CN 108425642A discloses a drill rod foundation, which mainly comprises a drill rod, a flange plate and a two-in-one plane chassis, wherein the bottom of the drill rod is provided with a guide blade, the upper end of the drill rod is provided with a spiral, and the foundation is drilled into soil during use. The drill rod foundation is small in size, simple to manufacture and convenient to construct. But this basis is only suitable for use as a compact basis. In addition, the base material is metal, which is not suitable for repeated use. Meanwhile, the drill rod foundation mainly depends on the drill rod to penetrate into the ground to play a role in stabilizing the upper structure, and the stability of the foundation depends on the geological structure to a great extent, so that the foundation has certain limitation in use and cannot be applied to areas with poor geological conditions.
The invention patent with the patent number of CN 109162290A discloses a rivet foundation. The rigidity of the whole system is improved through the variable cross-section bearing platform of the nail cap, the variable cross-section bearing platform further acts together with the nail body, the capability of resisting transverse deformation and rotation of the system is improved, and the variable cross-section bearing platform can resist vertical deformation, transverse deformation and rotation deformation of a foundation under the action of external strong load. The invention has complex structure, the nail cap and the nail body are formed by casting concrete in situ, the construction difficulty of foundation construction is higher, the construction period is longer, and the cost is higher. The invention is suitable for large-scale foundation engineering.
The invention patent number CN 108239991A discloses a concrete assembled cup-shaped foundation, which mainly comprises a foundation chassis, a foundation cup opening and a foundation upright post which are connected in an assembled manner, wherein the foundation chassis, the foundation cup opening and the foundation upright post are all of concrete structures, and all structures are connected through plug connection. The invention solves the problem that the construction progress is easily affected by seasons and weather in the field construction process of the existing foundation. However, the invention is of a full concrete structure and has higher production cost. The foundation chassis, the foundation cup opening and the foundation upright post are large in volume and heavy in weight, and the assembled foundation is large in transportation difficulty and high in transportation cost in the process of being transported to a construction site. In addition, the foundation related to the invention can bear the longitudinal load of the upper structure well, but has no strengthening effect on the transverse stability of the upper structure.
