Neden is Kazısız Sondaj Teknoloji Gerekli?

Ne olursa olsun of of the the planning of çeşitli endüstriler değil yer 2c fakir koordinasyon, veya altyapı kalkınma ihtiyaçlar, yeni yeraltı tesisler var her zaman artıyor. At bu zaman, ya kazı veya kazı yapılmaz olmalı seçilmiş.

As the advantages of non-excavation are gradually recognized by people, the technology of non-excavation is becoming more and more mature, and the cost of non-excavation construction is decreasing year by year, so the application of non-excavation is increasing year by year.

Underground pipelines are an important part of urban infrastructure. Cable pipes, upper and lower water pipe networks, and thermal (power) pipelines, together with underground railways, are called the lifeline of cities. With the development of society, the length of underground pipelines continues to increase. On the other hand , my country's per capita pipeline share is far lower than that of Western developed countries. The reason why trenchless technology has received more and more applications and attention is due to its inherent technical advantages and the huge desire brought about by social development. The main manifestations are: (1) Underground travel is an inevitable requirement of social development. Regardless of whether the planning of various industries is not in place, poor coordination, or infrastructure development needs, new underground facilities are always increasing. At this time, either excavation or non-excavation must be chosen. As the advantages of non-excavation are gradually recognized by people, the technology of non-excavation is becoming more and more mature, and the cost of non-excavation construction is decreasing year by year, so the application of non-excavation is increasing year by year. Underground pipelines are an important part of urban infrastructure. Cable pipes, upper and lower water pipe networks, and heat (power) pipelines, together with underground railways, are called the lifelines of cities. With the development of society, the length of underground pipelines continues to increase. Trenchless There is huge room for growth in the market.

(2) In areas without excavation conditions, it is impossible to excavate and lay pipelines after the construction of bridges, buildings, and tunnels in cities where non-excavation has advantages. Although some have surface excavation conditions, non-excavation has become the best method because the pipeline is buried too deep and the groundwater level is high. The application field of horizontal directional/guided drilling technology is environmental treatment engineering. Pollutants such as some large garbage disposal sites, industrial waste dumps, aircraft fuel depots at airports and air force bases, underground fuel storage depots, oil refineries, and gas stations seep underground under the action of rainwater, polluting groundwater and soil. Use horizontal directional/guided drilling technology to drill horizontal wells in polluted areas, and lay filters in them to pump out polluted groundwater and prevent further spread of pollutants. In addition, the following treatment methods can also be used: air injection and soil gasification extraction; recovery of free products (light or heavy non-dissolved liquid); biological treatment (injecting medium to accelerate the decomposition rate of pollutants); Extraction leaching and chemical stabilization; soil monitoring and sampling. The ground road network is crisscrossed, underground facilities are crisscrossed, and the functional division of urban blocks has become an insurmountable obstacle for conventional engineering construction. There is a strong demand for trenchless technology. The obstacles that may be crossed during municipal construction include: the existing underground municipal pipe network, subway network, road network, underground space and underground facilities, buildings, rivers, cultural relics protection sites, etc. It is almost impossible to complete it with traditional construction methods, and the non-excavation method is duty-bound.

(3) Kazısız has rekabetçi avantajlar böyle çevre koruma ve yaşanabilirlik. Eğer miktar kazı içinde a şehir aşar a kesin yüzde, it irade kaçınılmaz etki trafik ve normal yaşam vatandaşların. kazı yapmayan inşaat yapmaz engellemez trafik, kirlet çevre, yok et bitki örtüsü, duygulanım çevre binalar, veya duygulanım duygulanım normal yaşam ve iş düzen sakinlerin.

(4) İçinde bazı projeler, kazı yapılmayan has a karşılaştırmalı avantajlı. Maliyet kazı yapılmayan inşaat yapmaz yapmaz artar çok çok olarak derinlik artar, ve o can ayrıca çapraz nehirler, göller, demiryolları, otoyollar, kentsel binalar, vb. uygun o en kısa makul yol. O vardır yüksek verimlilik, tasarruf malzeme tüketim, ve azaltır inşaat maliyetler, so kazısız has karşılaştırmalı avantajlar in baz projeler.
