Technical Field

The invention relates to a deformation joint device of a corrugated steel plate pipeline structure, which is used in the fields of embedded corrugated steel pipelines, channels, bridges and culverts and subway engineering and is used for preventing uneven settlement of a foundation and expansion and settlement of the corrugated steel structure caused by temperature change.

Background

The corrugated pipe is used in the first british in the 80 s of the 18 th century, and the feasibility of the corrugated channel and the culvert pipe is researched in the beginning of the united states at the end of the 19 th century, and the corrugated channel and the culvert pipe are firstly applied to culvert engineering. Corrugated plate culverts were first applied to field irrigation near scotland burgh, england in the beginning of the 20 th century, corrugated plate channels of central railways in illinois were tested by the american railway engineering association in 1923, corrugated pipes were first applied in canada during coal mine construction in the 20 th century, corrugated pipe (plate) automobile channels with a span of 8 meters were first built in australia in the beginning of the 20 th century 30, corrugated pipe design specifications were compiled in the 20 th century ninety-year, japan highway design specifications. The widespread use of corrugated tubing in various countries throughout the world has demonstrated that such structures not only have very broad applicability, but also have a life that far exceeds their design life.

In many countries, such as the united states and canada, corrugated culvert is widely used in various highway engineering, even highway engineering, and its construction design manual is more endless, and thus accumulates more mature construction design methods and experiences of corrugated pipe, and most of them are still conservative. According to the current foreign research and application, the research on the stress expansion and contraction and deformation of the steel corrugated pipe culvert is not much.

The corrugated pipe is applied after China is built, in the construction of Qinghai-Tibet highways in the 50 th century, corrugated pipe holes are used in the process of rush-repair in the 20 th century, and the corrugated pipe holes can still be normally used until the soil is excavated in the 70 th century. In 1965, a steel corrugated pipe water through hole installed in the United states in the second war period was dug out on the Yunnan Burmese road. In autumn 1998, a corrugated pipe culvert with a diameter of 1 meter was dug in the sea, and the history of nearly 50 years to date was investigated as a military gateway used at that time. Later, due to various economic and political reasons, the corrugated pipe culvert cannot be designed and used more, after 1978, the national economy starts to recover, and special Shenzhen, coal producing areas, Shanxi and the like import the corrugated pipe and apply the corrugated pipe to a large number of culvert projects; china is officially applied to highway engineering until the end of the 90 s in the 20 th century.

In 3 years of 1996-1999, in the Qinghai-Tibet highway engineering, the first highway research and design institute of Zhongyu successfully solved the serious problem that the culvert is damaged or damaged due to frost heaving and thaw collapse in the frozen soil region by using 3 metal corrugated pipe culvert engineering.

At the end of the 90 s in the 20 th century, steel corrugated plate channels were applied to Shanghai Pudong International airports and No. four subway lines, and the steel corrugated plate channels mostly had arch, arc or ellipse shapes, and plate thicknesses varied from 2.5mm to 12 mm.

The culvert foundation stability problem of the great Khingan mountain plus desert highway is caused by the phenomena of frozen soil for many years, muddy land in a few areas and other unfavorable geology, and the corrugated pipe culvert is adopted later to adapt to deformation and settlement caused by freezing degradation for many years, wherein more than 100 corrugated pipe culverts are repaired, the galvanized plate is 1.0-2.5mm thick, the wave distance is 68mm, the pore diameter is 1.0m, and the wave height is 13 mm. After the culvert is normally operated for more than 1 year, the culvert of the corrugated pipe is comprehensively and systematically investigated, and the states of most of the culverts of the corrugated pipe are good except that a few parts of the culverts are poor in waterproof treatment, unsatisfactory in basic treatment, uneven settlement and deformation caused by improper construction, and the culvert has water accumulation or water seepage phenomena, and one part of the culvert of the corrugated pipe is not damaged due to the structure at present.

Because the green and healthy highway green clear water river section belongs to a typical degraded permafrost distribution area, the temperature of the permafrost of the section is relatively high, the distribution of the permafrost is uneven, and the permafrost is longer than the fusion area in a staggered manner, the culvert of the section has the phenomena of wrong tyre, cracking of a culvert platform, paving damage, overturning of wing walls, cracks of a tunnel body and the like. The reasons for this are mostly caused by shallow foundation embedment or repeated thawing and sinking and frost heaving. In order to prevent the phenomena and avoid the early damage of the culvert, the steel zinc corrugated pipe with the diameter of 150 cm is successfully tried in China in 2000. The research result and the years 2001 to 2002 are popularized to Xining Jiu-Zhi road, Dianhalashan Yuhai road, Huashi isthmus Dari road and the like, and as of 2002, the roads use 418 corrugated pipe culverts in total, the diameter of the corrugated pipe culverts is 8231.19 m, the diameter of the corrugated pipe is distributed between 150 cm and 250 cm, the wall thickness of the corrugated pipe is increased from 3mm to 5mm from the plateau, and the filling height of the top of the pit is greatly increased from 100 cm to 1700 cm.

The corrugated steel plate pipeline structure is a bridge span structure (such as a round pipe culvert, an arch bridge, a subway, a tunnel, a channel, a pipeline and the like) which is compacted by adopting structural backfill materials at the periphery of a pipeline so as to ensure that soil and a pipeline structure interact to bear load together, and the corrugated steel plate is a corrugated plate-shaped material which is made by adopting hot rolled steel plates and performing corrugated rolling and cold bending processing according to specified sizes. At present, the research on the design and construction of corrugated steel structures at home and abroad mainly aims at the following contents:

(1) researching the compressive stress of the corrugated steel structure in the limit state of the bearing capacity;

(2) in the construction and operation processes of the corrugated steel structure, the bending and compression stress resistance under the condition of plastic hinge is researched;

(3) researching the strength requirement of the longitudinal seam bolt connecting bolt of the corrugated steel structure;

(4) and (3) researching the flexibility requirement of the corrugated steel structure in the transportation process.

(5) And (3) researching deformation of the corrugated steel pipe when the foundation is unevenly settled.

In 12.16.2019, D66-01-2019, which is the most authoritative technical rule for the design and construction of the corrugated steel structure in China, is published by the highway corrugated steel culvert technical rule T/CECS (China engineering construction standardization Association) and is mainly compiled by units such as China Committee for research and design research institute, and the like, but the rule does not provide specific rules for the expansion and the settlement of the corrugated steel structure body.

At present, the corrugated steel structure is written by authoritative departments at home, represents the highest level of the corrugated steel structure design at home, and a construction manual, namely a corrugated steel embedded structure design construction manual, does not provide specific regulations for the expansion and the settlement of a corrugated steel structure body, so that the research difficulty of the expansion and the settlement of the corrugated steel structure under the action of temperature and external force is high, and continuous exploration and attack and customs are required.

At present, several connecting devices which are put into use in the market at home have poor waterproof effect, complex structure and higher investment.
