Embodiment

[0030] Such as figure 1 As shown, a pile-supported caisson seawall includes a caisson platform 100 located on a shallow seabed soft soil foundation. The caisson platform 100 is spliced ​​by a plurality of reinforced concrete boxes 101, and the number of boxes 101 is determined by the number of seawalls. Depending on the design length, the box body 101 is a cubic structure with an open upper end, and one side in the width direction of the box body 101 has a protruding connecting portion that protrudes outward, and the other side has a concave connecting portion that is concave inward. Two adjacent boxes 101 are spliced ​​together through the protruding connection part and the concave connection part, and the top view of the caisson platform 100 formed by the connection is as follows figure 2 As shown, an elongated box body 101 can be provided at intervals, such a structure can improve the overall anti-horizontal thrust and anti-overturning capabilities, and the side view of th...

Abstract

The invention relates to a seawall and a construction method thereof, and aims to provide a seawall with better stability, taking a large-diameter cast-in-site concrete cylindrical pile as a basis, and a construction method of the seawall, wherein the upper part of the seawall is connected with a caisson platform. The pile bearing caisson seawall comprises the caisson platform positioned on a submarine soft soil foundation in coastal engineering, wherein, the bottom of the caisson platform is equipped with at least two rows of erected bearing piles which are used for bearing the platform and are embedded into sea bottom; and the sides of the caisson platform near sea and land are equipped with the erected bearing piles which are embedded into the sea bottom as well as transverse suppression layers positioned on the top ends of the bearing piles. The seawall and the construction method have the beneficial effects that the bearing capacity and stability of the seawall are improved; and in addition, the caisson platform can be utilized as a construction platform so as to construct according to an overland construction method after construction machinery is placed on the platform, which reduces offshore ship operation and lowers construction cost, thus being capable of being widely applied to coastal dam construction engineering.

Description

technical field [0001] The invention relates to a seawall and a construction method thereof, in particular to a large-diameter cylindrical pile-supported caisson seawall and a construction method thereof. Background technique [0002] With the continuous deepening of my country's reform and opening up, my country's economic construction has developed steadily and rapidly, especially the economic development of coastal areas has achieved world-renowned achievements. As we all know, land resources are an important basis for economic development. With the rapid development of the economy, construction land is becoming increasingly scarce. It has become a consensus in coastal economically developed areas to ask for land from tidal flats. In addition, the number of foundation pit enclosures and foundation treatments for housing construction However, the rockfill embankment method in the previous land reclamation project requires a large amount of mining and use of stone materials...
