Embodiment Construction
[0041] The following is attached Figure 1-3 The application is described in further detail.
[0042] On the one hand, the embodiment of the present application discloses a cast-in-place box girder support foundation on a muddy soft foundation. refer to figure 1 The foundation of cast-in-place box girder support on silty soft foundation includes foundation cushion 1 installed in the trench of the construction site. The foundation cushion layer 1 includes a plurality of foundation laths 11 spliced with each other, and the foundation lath 11 includes a plurality of unit prefabricated concrete panels 111 spliced along the length direction of the foundation laths 11 .
[0043] refer to figure 1 The opposite sides of the unit prefabricated concrete slab 111 are provided with fixed chute 1111, the fixed chute 1111 runs through the opposite two sides of the unit prefabricated concrete slab 111, and the cross section of the fixed chute 1111 is dovetail-shaped. The unit prefabr...

The invention relates to a mucky soft foundation cast-in-place box girder support foundation and a construction method thereof, and belongs to the technical field of bridge construction, the mucky soft foundation cast-in-place box girder support foundation comprises a foundation cushion layer, the foundation cushion layer is provided with a plurality of mutually fixed foundation battens, and the foundation battens are arranged in the width direction of the foundation battens; the foundation batten comprises a plurality of unit prefabricated concrete plates which are fixed to one another. According to the construction method, the foundation cushion layer is arranged to be the multiple unit prefabricated concrete plates which are spliced and fixed, the unit prefabricated concrete plates are spliced and fixed into the foundation cushion layer while the groove is dug in the construction site, and compared with the mode that the foundation cushion layer is poured through concrete, the concrete cooling time is shortened, so that the construction time of a foundation is shortened, and the construction speed of the foundation is increased.
Description
technical field [0001] The present application relates to the technical field of bridge construction, in particular to a cast-in-place box girder support foundation on a silty soft foundation and a construction method thereof. Background technique [0002] With the improvement of bridge technology in our country, the quality requirements of bridges are getting higher and higher. The cast-in-place box girder plays an important role in bridge construction because of its simple shape, high torsional rigidity, good integrity, and strong applicability. effect. [0003] Before the cast-in-place box girder is installed, the foundation needs to be treated first. The existing foundation treatment is usually to dig a trench at the construction site and fill the trench with reinforced concrete, so that the bottom of the cast-in-place box girder is more stable. [0004] In view of the above-mentioned related technologies, the inventor believes that the reinforced concrete filled in the...
