Embodiment Construction
[0047] The accompanying drawings show the technical solution of the present invention and its embodiments, and the relevant details and working principles of the embodiments will be further described below in conjunction with the accompanying drawings.
[0048] refer to figure 1 , figure 2 , image 3 As shown, the super-large cofferdam of bamboo raft piles provided by the present invention includes at least three layers of bamboo fence 1, and the bamboo fence 1 described in this embodiment is provided with three layers from the inside to the outside, and each bamboo fence The height of the wall 1 gradually decreases from the inside to the outside. The bamboo wall 1 includes a moso bamboo frame 2 constructed of moso bamboo poles. The moso bamboo crossbar 5 that is set, the positions of the moso bamboo stake 3, the moso bamboo strut 4 and the moso bamboo crossbar 5 intersect are bound and fixed, the moso bamboo pile 3 is driven deep into the soil, and the moso bamboo fence 1 ...

The invention discloses a bamboo raft pile oversized cofferdam. The bamboo raft pile oversized cofferdam comprises at least three layers of bamboo fence retaining walls of which the heights are gradually reduced from inside to outside; each bamboo fence retaining wall comprises a moso bamboo frame erected by moso bamboo poles; a blow-filling region is formed in the inner layer of the bamboo fence retaining walls in a surrounding way; a first suppression region is formed between the second layer of the bamboo fence retaining walls and the inner layer of the bamboo fence retaining walls; a second suppression region is formed between the second layer of the bamboo fence retaining walls and the third layer of the bamboo fence retaining walls; each of the first suppression region and the second suppression region is filled with a sludge suppression layer; the height of the top surface of sludge of the blow-filling region is greater than that of the top surface of sludge of the first suppression region; the height of the top surface of the sludge of the first suppression region is greater than that of the top surface of sludge of the second suppression region. The bamboo raft pile oversized cofferdam has the following advantages that the construction is simple and convenient, and the construction duration is short; the construction cost is low; the environment-friendly degree of construction is high, and the environment cost investment is favorably reduced. The invention also provides a construction method for sea reclamation by adopting the bamboo raft pile oversized cofferdam.
Description
technical field [0001] The invention relates to a super-large cofferdam of bamboo row piles, in particular to a building cofferdam for land reclamation from the sea. The invention also relates to a construction method for land reclamation by adopting the above-mentioned super-large cofferdam of bamboo raft piles. Background technique [0002] With the rapid development of economy and society, the scale of construction in coastal areas is rapidly expanding, and the contradiction between land as a limited precious resource and the supply and demand of construction land is becoming more and more prominent. An important way to solve this contradiction is to seek land from the sea. Large-scale "land reclamation" has always been a major measure to expand land use in many countries. The cofferdam project is of great significance to the overall construction of the reclamation project. Traditional cofferdams generally use sand bag cofferdams, but due to the increasingly scarce sand...
