Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] Such as figure 1 As shown, the deep-water bare rock riverbed 3 generally consists of a partially weathered rock formation 31 and a complete rock formation 32 in sequence. The invention provides a method for constructing caisson foundations suitable for deep-water bare rock, which includes the following steps:

[0035] Step one, combine figure 1 and image 3 Firstly, underwater blasting and slag removal are carried out to excavate the rock surface of the riverbed to the complete rock formation 32 to form a rock foundation pit 33 . At the same time, a caisson 1 is manufactured on the bank. The caisson 1 includes a well wall 11 and a multi-channel bottom compartment 12 positioned inside the well wall 11 , and a section of water retaining cofferdam 2 is connected above the well wall 11 . The well wall 11 is 1.5m-2.0m thick, and is a hollow structure surrounded...

Abstract

The invention discloses an arrangement type sunk well foundation construction method applicable to deepwater bare rock. The construction method includes the following steps that 1, underwater blasting and slag removing are carried out firstly, a river bed ledge is excavated to a complete rock stratum to form a rock foundation pit, meanwhile, a sunk well is made on the bank, and after being made, the sunk well is transported to the position above the rock foundation pit in a floating manner; 2, the sunk well is arranged at the bottom of the rock foundation pit accurately; 3, the sunk well is utilized as a skeleton and a formwork, and foundation concrete is poured multiple times; and 4, anchor ropes are demounted, supporting and leveling supports on the concrete are cut off, water in the sunk well is drained completely, and a sunk well cover plate and piers are sequentially poured in a water-free environment. According to the arrangement type sunk well foundation construction method, verticality of the sunk well is adjusted accurately by means of multiple jacks. Moreover, a moving baffle is jacked and pressed by the bottom of the rock foundation pit to automatically stretch or contract up and down to be adapted to unevenness of the bottom of the rock foundation pit. The concrete is poured multiple times to be formed. Installing is flexible and convenient and beneficial to construction, the operation difficulty is lowered greatly, and installing quality is improved.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to an installation type caisson foundation construction method suitable for deep water bare rock. Background technique [0002] At present, in domestic bridge projects, when the water depth is relatively deep and the bottom of the water is exposed rock formations, bored pile foundations are generally used. In the construction process of this foundation form, a drilling construction platform needs to be set up in the water first, and a drilling rig is placed on the drilling construction platform to carry out bored pile construction; tower. The scale of temporary construction facilities is large, and there are many installation and dismantling procedures. Especially as bridge projects are increasingly developed towards the sea, the water depth of tens of meters or even hundreds of meters and the harsh marine construction environment make the cost of temporary construction facilitie...
