Problems solved by technology

With the rapid development of the economy, the land space planning is constantly changing according to the needs of economic development. It is extremely difficult to develop and utilize land in the new reclamation area composed of high-moisture content silt that only drains the surface water of the reclamation area, especially in In the new dredging and reclamation area with large area and deep silt, due to insufficient bearing capacity, large land machinery and equipment cannot enter the new dredging and reclamation area for construction, and water machinery and equipment cannot be deployed in the new dredging and reclamation area, so it is impossible to complete the new Excavation and support of dredging land ditches
For the construction of the water system communication project in the new land reclamation area, the width of the water system communication channel is large, and silting often occurs during the excavation process, the construction cost is high, the progress is slow, and even the project cannot be completed

Embodiment Construction

[0029] combined with Figure 1-3 , the specific embodiments of the present invention are described as follows:

[0030] like Figure 1-3 As shown in the figure, a construction method for forced vertical encroachment and embankment construction of water system ditches in newly reclaimed land areas includes the following steps:

[0031] S1. Fill the first-class dam:

[0032] The construction is carried out by the occupation method. After unloading, the bulldozer is used for rolling in layers, and a new dam is backfilled with dry soil on both sides of the upper outlet line of the design of the water system communication channel. Step 2. The width of the top of the first-class dam 1 should be set to be greater than 1.5 times the width of the excavator chassis, which can give the excavator enough working surface; the slope ratio of the first-class dam 1 is set to 1:3, which is conducive to the stability of the dam and acts as a The foundation for the subsequent multi-level dam ...

Abstract

The invention discloses a forced vertical occupying diking construction method for a new hydraulic reclamation land area water system ditch, which comprises the following steps: S1, filling a first-stage dam, S2, supporting slide-resistant piles of the first-stage dam, S3, dredging the outer side of the ditch dam, S4, carrying out layered dredging on the ditch for the first time, S5, filling a second-stage dam and building a second-stage step, and S6, supporting slide-resistant piles of the second-stage dam. And S7, circularly dredging and filling an n-stage dam to the bottom of the new hydraulic reclamation land area, and carrying out other steps, so that the inner side of the dam is excavated to form a new hydraulic reclamation land area water system ditch. The construction method is simple, and the built dam is large in bearing capacity, good in stability and not prone to overturning; and back silting is not prone to occurring in the ditch excavation and supporting process, construction cost is low, progress is fast, efficiency is high, operation is convenient, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of water system communication engineering construction in newly reclaimed land areas, in particular to a construction method for forced vertical entry and embankment of water system ditches in newly reclaimed land areas. Background technique [0002] The dredging construction of large rivers and lakes usually adopts cutter suction dredgers. The excavated sludge is transported through the sludge discharge pipeline to the built sludge discharge area to form a filling area. The saturated soil mass needs to be developed and utilized by machinery after years of drainage consolidation and natural air drying under the action of self-weight stress. With the rapid development of the economy, the national land space planning is constantly changing according to the needs of economic development. It is extremely difficult to develop, construct and utilize land in the newly reclaimed land area composed of silt with high ...
