Embodiment Construction

[0076] The present invention will be further described in detail below in conjunction with the accompanying drawings and actual test cases of the inventive method.

[0077] This construction example is the revetment project of the Dongliu waterway in the 6-meter water depth waterway regulation project of the Wuhan-Anqing section of the Yangtze River trunk line. During specific construction, the steps are as follows:

[0078] 1. Construction scheme design

[0079] ① Collect the basic parameters required for construction scheme design, such as figure 1 , figure 2 As shown, the basic parameters of this instance are as follows:

[0080] Table 1 Example basic parameter list

[0081]

[0082]

[0083] ②Determine the number of traction equipment: calculate the number of excavators to be used in construction, and the required traction force calculated according to formula (1) is 237kN; according to formula (2), the required number of excavators is 3, and the safety factor i...

Abstract

The invention provides a construction method for laying interlocking block soft mattress in an upper-beach shallow end under a low water level. The construction method comprises the steps of binding concrete interlocking blocks on an arrangement boat to make the soft mattress, arranging traction equipment on a bank slope, making a traction rope connected with the traction equipment and a tractionsteel beam, using a polypropylene rope to bind the traction steel beam and the soft mattress bond with the concrete interlocking blocks, and then pulling the soft mattress on the arrangement boat to adesigned position of the upper-beach shallow end through the pulling equipment to achieve laying construction of the soft mattress of the upper-beach shallow end under a low water level at a time. Compared with the prior art, the construction method solves the problems in the prior art that under a low water level, mat arrangement of the upper-beach shallow end under the low water level and the placement of concrete interlocking blocks are separately conducted, and the soft mattress cannot be laid as a whole; and meanwhile, the construction method has the advantages of being safe in construction, high in quality and efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of river bank protection construction, and in particular relates to a construction method for laying a concrete interlocking block soft row in a high beach shallow water area under a low water level. Background technique [0002] High beach is a kind of floodplain with high beach surface elevation, which is submerged in flood season and has a large exposed area in dry season. When the water level is low in the dry season, during the construction process of laying concrete interlocking block soft row revetment on the high beach, there is a shallow water area with a gentle slope and a large area between the laying ship and the bank slope. Due to the insufficient draft of the laying ship, it is impossible to carry out near-shore construction. The current high-beach paving construction methods mainly include: 1. Construction methods under low water level: dozens of workers drag the pads to the designed head pos...
