Problems solved by technology
[0004] The method and device for backfilling the shore zone of the present invention solve the problem that the materials in the prior art are easy to disperse and have poor cohesiveness, and because of their large self-weight, they will generate a lot of earth pressure on the bank wall, and at the same time, it will also affect the underlying foundation. A large gravity load is generated, so it is necessary to increase the size of the foundation and carry out foundation treatment to improve the bearing capacity of the foundation, thus increasing the problem of construction costs

Embodiment Construction
[0027] figure 1 It is a schematic flow chart of an embodiment of the method for backfilling the shore zone of the present invention. Such as figure 1 As shown, the method for backfilling the shore zone of the present invention includes the following steps.
[0028] Step S1. Fill the soil material and the curing agent into the transmission pipeline 3, and transport it to the shore zone 4 by the transmission pipeline 3 to backfill the shore zone 4.
[0029] Specifically, the soil material and the curing agent are mixed to form a solidified soil material. Since the solidified soil material is poured underwater, in order to ensure that the solidified soil material does not disperse during the sinking process through the water layer, the physical properties of the soil and the components of the curing agent Certain requirements must be met. In addition to making the solidified soil harden to meet the required strength, the curing agent also needs to ensure that the mixture does n...

The invention provides a backfilling method and device of a shore-connecting zone. The method comprises the following steps: forming packing by an earth material and a curing agent and injecting the packing into a conveying pipeline; and conveying the packing to the shore-connecting zone through the conveying pipeline for backfilling the shore-connecting zone. The invention further provides the device for backfilling the shore-connecting zone. According to the method and device, the self-weight of backfilled materials is reduced, soil pressure generated by the pile-up effect is reduced and the risk that a subjacent foundation has landslide due to instability is reduced; and moreover, the scale of the foundation and the treatment scale of the subjacent foundation are reduced, and the cost is reduced.
Description
technical field [0001] The invention relates to the field of port construction, in particular to a method and device for backfilling a shore zone. Background technique [0002] The wharf is a hydraulic structure on the seaside or river for large ships to dock, get on and off passengers, and load and unload goods. It is a long embankment extending from the shore to deep water. When the wharf is built manually, after the foundation and the shore wall are built in the deep water area, a slope-shaped water area with gradually decreasing water depth will be formed between the shore wall and the coast, which is called the shore zone. It is necessary to solidify the soil material to the shore zone and level the site to complete the subsequent construction of the upper platform. The backfilled site needs to have sufficient strength and modulus of deformation. Therefore, there are higher requirements for the solidified soil material, that is, the backfill process. [0003] In the ...
