Background
In a soft soil area, the soft soil has strong thixotropy and low bearing capacity, so that the soft soil foundation can meet the bearing capacity requirement of the foundation only by foundation treatment. In construction, different soft foundation treatment technical schemes are adopted according to geological exploration conditions. Generally, in the same engineering project, two different soft foundation treatment forms often exist in consideration of the soft foundation treatment cost or the construction period.
The construction of urban underground pipe galleries is being actively and vigorously carried out nationwide. Many times this practice thrift city construction land and consider, underground pipe gallery all builds under urban road. In the soft soil foundation region, the non-underground pipe gallery region (totally two, do not build the underground pipe gallery under it) of underground pipe gallery and urban road all needs to handle respective soft soil foundation just can satisfy the bearing capacity requirement, and when both foundation treatment methods are different, can produce the difference and subside, causes the road crack when serious, influences driving safety. The conventional crack treatment mode is to completely remove urban roads and re-pave asphalt concrete or concrete pavements, so that the treatment cost is high and traffic jam is caused.
For example, as shown in fig. 1, the underground pipe gallery 1 is built on the soft soil foundation of the silt in a certain south, the urban road 2 is built on the underground pipe gallery 1, namely, the underground pipe gallery 1 is built below the urban road 2, the part of the urban road above the underground pipe gallery 1 becomes the underground pipe gallery area 21, the soft foundation 3 of the pipe gallery under the underground pipe gallery 1 adopts the PHC high-strength prestressed concrete pipe pile foundation, namely, the PHC pile foundation 31, and the soft foundation 4 of the road under the non-underground pipe gallery area 22 of the urban road 2 connected with the underground pipe gallery adopts the plain concrete pile composite foundation 41.
Because between the PHC pile foundation 31 under the utility tunnel 1 and the plain concrete pile composite foundation 41 under the non-utility tunnel region 22 of urban road 2, there is uneven settlement between rigid pile and the composite foundation, the settlement difference is great, can cause the bituminous paving (namely the juncture of the utility tunnel region 21 of urban road 2 and the non-utility tunnel region 22) to produce fore-and-aft crack 5 above the 1 lateral wall of utility tunnel, when the settlement difference is great in fore-and-aft crack 5 both sides, the travelling comfort of driving is directly influenced, under the serious condition, influence driving safety, be the problem that needs focus on and try to solve.
In order to solve the problem of longitudinal cracks, a method for repairing generated cracks is mostly adopted in the past, the method increases construction cost, and cracks are generated again if uneven settlement continues to develop.
Therefore, the structure and the method for solving the problem of uneven settlement quality at the junction of the underground pipe gallery of the urban road are needed, the crack does not need to be repaired, the treatment scheme is simple and feasible, and the treatment cost is greatly saved.
