specific Embodiment approach 1

[0022] Specific embodiment one: the low-pile gravity wharf suitable for soft ground in this embodiment includes a plurality of rigid foundation piles 10, a reinforced concrete structure floor 40, plain concrete walls 50 and reinforced concrete topping 60, the low-pile gravity wharf The structural foundation adopts rigid foundation pile 10, the bottom of rigid foundation pile 10 is inserted into the hard soil layer, the upper part of rigid foundation pile 10 is laid gravel cushion 20 and plain concrete cushion 30 in sequence, and the top of rigid foundation pile 10 is poured with steel bars The concrete structure bottom plate 40, the upper surface of the reinforced concrete structure bottom plate 40 is provided with a plain concrete wall body 50, and the top surface of the plain concrete wall body 50 is provided with a reinforced concrete topping 60, and the wall behind the plain concrete wall body 50 is arranged sequentially from bottom to top There are riprap backfill structur...

specific Embodiment approach 2

[0025] Embodiment 2: This embodiment is different from Embodiment 1 in that the rigid foundation pile 10 is a PHC pile or a cast-in-situ pile.

specific Embodiment approach 3

[0026] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the top part of the rigid foundation pile 10 enters the reinforced concrete structure bottom plate 40, and the depth of the top entering the reinforced concrete structure bottom plate 40 is 10-50 cm.

Abstract

The invention relates to a low pile gravity type wharf suitable for a soft soil foundation and a construction method of the low pile gravity type wharf, and belongs to the field of wharfs, which solves the problems that an existing gravity type wharf is influenced by foundation soil properties, large post-construction settlement exists commonly, and the construction period is long. The low pile gravity type wharf includes a plurality of rigid foundation piles, a reinforced concrete structure base plate, a plain concrete wall body and a reinforced concrete copping, wherein the structure foundation of the low pile gravity type wharf adopts the rigid foundation piles, the bottoms of the rigid foundation piles enter a hard soil layer, a broken stone cushion layer and a plain concrete cushion layer are sequentially paved on the upper parts of the rigid foundation piles, the reinforced concrete structure base plate is casted on the tops of the rigid foundation piles, the reinforced concretecopping is arranged on the top surface of the plain concrete wall body, and a riprap refilling structure layer, an inverted filtering layer, a geotechnical cloth and a dang residue layer are sequentially arranged on the rear of the plain concrete wall body from the top to the bottom. According to the low pile gravity wharf and the construction method, properties of the rigid foundation piles are used, settlement and horizontal displacement can be effectively controlled, the reinforcing effect of whole stability on the wharf is also achieved, and the construction period of the wharf is effectively shortened.

Description

technical field [0001] The invention belongs to the field of wharves, and in particular relates to a low-pile gravity type wharf suitable for soft soil foundations and a construction method thereof. Background technique [0002] Gravity wharf has dual functions of ship berthing and soil retaining, and has a long history of use. However, the wharf structure has high requirements on the bearing capacity of the foundation, and the settlement displacement is controlled by the properties of the foundation soil, which generally has a large post-construction settlement. Reliable foundation treatment measures must be taken to construct a gravity wharf on soft soil foundations such as muddy soil, clay, and silt. At present, the treatment depth of foundation methods such as foundation soil replacement and riprap silting are relatively limited, and the treatment results are generally unsatisfactory; blasting silting has a great impact on the safety of surrounding existing structures (...
