Background
With the increasingly perfect functions of modern buildings, the types of buried pipes in buildings are increasingly diversified, and specifically, the buried pipes can be divided into the following types according to the different functions of the buried pipes: various types of buried pipes such as electric power, communication, gas, water supply, heating power, drainage and the like are adopted, and the number of the buried pipes is increased while the types of the buried pipes are increased.
When the building is built on a soft foundation, the soft foundation treatment is generally required to be carried out on the building foundation, so that the bearing capacity of the foundation soil can meet the bearing capacity requirement of the building. The post-construction settlement of the building treated by the soft foundation is generally smaller. In the conventional engineering method, when laying underground pipe laying pipes outside a building, a foundation pit is excavated, after the foundation pit is excavated to a designed height, the surface of the foundation pit is roughly leveled, then the pipe laying pipes are directly laid in the foundation pit, and then the ground is backfilled to the original ground height by using original soil. In engineering practice, special soft foundation treatment is generally rarely carried out on a soft foundation where the buried pipe is located. The result of this is: when the underground water level is high, after the buried pipe is laid according to the method, the buried pipe section outside the building is usually subjected to uneven settlement due to consolidation, settlement and the like of upper-layer covering soil, when the uneven settlement is large, the buried pipe is usually subjected to fracture, leakage and the like, and great challenge is provided for normal operation of the buried pipe.
The buried pipe is generally difficult to maintain after being broken and leaked, and in the conventional engineering practice, large excavation is generally needed to be carried out at the damaged part of the buried pipe during maintenance, so that the buried pipe is maintained after the damaged part of the buried pipe is exposed. This results in a long maintenance period and high costs for the buried pipe. Meanwhile, the maintenance and shutdown of the buried pipe bring much inconvenience to the work and life of users in the building, and the economic loss caused by the inconvenience is large. Therefore, technical improvement on the conventional pipe laying method is urgently needed.

Secondly, the construction of the cover plate ditch can be rapidly carried out after the excavation of the pipe-buried foundation pit is finished by adopting the geotextile, so that the construction period of the cover plate ditch is greatly saved; through set up the bottom plate preformed hole on apron ditch bottom plate, can make the bottom plate downside secret infiltration can pass through apron ditch bottom plate fast to the probability that messenger's apron ditch emergence anti superficial destruction reduces greatly.
When the cover plate ditch is wholly settled, and then the buried pipe is lifted to the original design elevation before settlement along with settlement, the lower part of the buried pipe is backfilled and tamped, and then the buried pipe falls back, so that the quick adjustment of the uneven settlement of the buried pipe is realized.
Has the advantages that: through adopting the utility model discloses a lap ditch for laying underground pipe laying. On one hand, the phenomenon that the common pipe burying position is easy to have uneven settlement is greatly reduced, the phenomena of leakage, breakage and the like of the pipe burying position caused by the frequent uneven settlement at the pipe burying position are effectively reduced, and the operation and maintenance cost of the pipe burying in the operation period is greatly reduced; on the other hand, after the cover plate ditch is unevenly settled to further cause uneven settlement of the buried pipe, the buried pipe is backfilled and tamped, so that elevation adjustment of uneven settlement of the buried pipe can be quickly realized, and further the buried pipe is prevented from being continuously settled to further cause damage. The novel cover plate trench has wide engineering application prospect.
