Rapid construction wharf structure on soft soil foundation and its construction method

Abstract

The invention discloses a novel wharf structure quickly constructed on a soft foundation, and belongs to the field of wharf engineering. The novel wharf structure comprises two rows of long piles and two rows of short pile plates which are symmetrically arranged, the two rows of short pipe plates are respectively arranged inside the two rows of long piles in an opposite direction, a short plate pile is arranged between two adjacent long piles in each row of long piles, and a joint between every adjacent short plate piles is covered by the long pile arranged outside the short plate pipes; geotechnical cloths are paved in the opposite sides of the two rows of short pile plates, an area for filling is formed between the geotechnical cloths at the two sides and internally and vertically provided with grouting pipes in an equal interval way, and rubble complexes are filled in the area. The invention further discloses a construction method of the wharf. By adopting the long piles and short pile plates, the wharf structure is simple, and the stability of the wharf can be improved; furthermore, the structure has the characteristics of being light in weight and smaller in additional load to the foundation; meanwhile, the construction method of the wharf structure is simple to operate and low in cost, and is likely to popularize and apply.

Description

technical field

[0001] The invention belongs to the field of wharf engineering, and in particular relates to a rapid construction wharf structure on soft ground and a construction method thereof. Background technique

[0002] The construction of the wharf plays an important role in increasing the volume of waterway passenger and freight transport and indirectly driving the economic development of the coastal and near-river areas. There are a large number of soft soil foundation structures in my country's coastal waters, rivers and lakes, which pose a challenge to the construction of the wharf. Construction at the same time The choice of the method is crucial to the construction period and the applicability of geological conditions.

[0003] Pile foundation is an important form of foundation and underground structure. It can not only bear the vertical load of the superstructure, but also bear the lateral load of the superstructure and soil. At present, the pile foundation has ...
