Greening an area of ??280.25 acres, the project mainly by the clean-up site, site preparation, the laying of topsoil to provide and planted trees and shrubs and other projects.
The 248.46 acres of green is mainly three-dimensional color blocks of trees in the plant configuration design and layout of the main take into account "to protect the green, with seedlings and forest" ecological visual effects.
Because it is winter and spring construction, seedlings planted better than other seasons, but also must strictly follow the norms of operation, planning, deployment, scientific and reasonable management methods, conscientiously do a good job every construction program, effective measures to ensure that the project Smoothly.
Construction preparation work (A) construction preparation: 1, the establishment of construction management system 2, establish and improve the technical management system 3, the production organization planning and implementation measures 4, integrated site management (B) construction preparation Specific content: 1, according to the design Drawings, organize relevant personnel on-site survey.
Comprehensively and conscientiously understand the topography, topography, obstacles, underground conditions and the current situation.
Design the best construction plan to find the construction difficulties as a key solution.
2, in accordance with the requirements of the design drawings, the site for a comprehensive positioning.
Level with the level to find out the level of piles to Grid grid coordinates for the control point, with a variety of marked piles terrain, elevation, civil elevation, planted loft.
3, connected to water, electricity, according to the actual situation of temporary temporary access roads, temporary facilities, storage yard and so on.
4, on the site of a few raw water for analysis and determination, to understand the PH value, soil properties, bulk density, organic matter content.
According to the requirements of plant growth, make necessary measures for soil improvement.
5, to understand the status quo of the surrounding road transport, transportation plans and methods to determine the normal operation of the transport project.
6, to understand the weather forecast during construction, including long-term forecasts, short-term forecasts, combined with specific construction necessary plans and adjustments to the plan.
7, the implementation of construction machinery, equipment, organizations, posts and personnel in the safe operation, quality requirements and so on before construction again training and education.
8, a clear site construction material staff conscientiously do a good job of the original data collation, accumulation, analysis, diary construction and various construction procedures, technical information archiving work.
9, clear materials, material preparation plan, including soil improvement implementation (analysis, testing), seedling sources, after the field research according to specifications, quantity, growth potential, pests and diseases, digging, packaging and transportation and other conditions.
Develop a plan for seedling programs.
Construction and deployment of construction and deployment is divided into: the construction of pre-construction work, construction site clearance, elevation positioning, lofting, earthworks, all kinds of material preparation and supply, green topography, green area planting loft, planting, site preparation, engineering maintenance management links Composed of.
1, the pre-construction organization, by the implementation of the organization and implementation of the ideological composition, by the leading group members together with the engineering commanding staff to form the project construction management team, engineers and technicians and the workforce.
And then the nature of the project, tasks, requirements, technical drawings drawings, the development of various rules and regulations, classification and management regulations.
At the same time, we will organize all kinds of equipment to mobilize before construction and mobilize one week before construction starts.
2, before entering the construction site, first solve the temporary housing, electricity, water, storage yard, warehouse, temporary access and other work.
Then the site to conduct a comprehensive clean-up.
At the same time determine the elevation point, to determine the various types of pile height and lofting and positioning work.
3, after the end of the above project, begin earthworks including soil improvement on site, deep salt draining and formation.
4, at the same time by a person responsible for the procurement of various materials, the development of procurement plans, supply arrangements, storage management, distribution plans and procedures, as well as the re-examination of materials and so on.
5, green construction in the topography, shape, soil modification, and then re-afforestation planting gray line, bamboo lofting positioning, retest and correction.
6, the last is greening and post-implementation management, the establishment of a person responsible for the maintenance team, the development of standardized conservation regulations, inspection system and rewards and punishments.
The above work arrangements must be ring ring fastening, there is synchronization, there are alternating, for the scene commander and construction crew to be well arranged at the scene, timely adjustment of work arrangements (such as climate change, etc.), the responsible persons of the various categories should Coordinate construction, cooperate with each other so that the project can be carried out normally.
Construction Methods and Technical Measures of Main Projects (I) Earthwork: Earthwork is the foundation of plant growth. The good and bad are directly related to the growth and development of the plants. It is the key to the healthy growth of seedlings. Therefore, it must be strictly according to plan.
1, Construction site cleaning, tillage, formation.
Due to the characteristic analysis of the soil in the block, the soil is a marine sediment in the plain area. Due to the recent reclamation, the parent material is a marine sediment with uniform particles and high silt content. The ground is subjected to deep inversion of about 0.40-0.50 cm so as to make the soil loose Breathable, easy to drain.
In the future conservation management, more organic fertilizer, long-term interests of the above measures are necessary.
2, a reasonable consideration of drainage ditches, combined with the entire block of water system, interoperability.
3, earthwork construction, the level measured with the level of points, elevation.
Use different standard pile to set different elevation, use gray line to release the range line. According to the priority construction method, there is a earthwork map in advance to reduce the repetitive operation and do the best possible.
4, the initial end of earthwork, should be re-measured elevation, found that the error corrected in time.
5, earthwork excavation work, should make plans in advance to avoid duplication of excavation.
(2) Greening construction plan: 1. Preparation of soil and soil quality 1) Earthworking The site of each greening area is arranged on the basis of ensuring the quality of all earthwork. At the same time, for the planting of different types of plants The location of processing.
Among them, the effective soil layer in arbor planting area is above 1.0M, the soil layer in shrub planting area is above 0.6M, the depth of lawn and flower is not less than 0.35M.
Perennial woody flower depth greater than 0.45M.
2, seedling selection 1), a variety of species of seedlings are used for the construction of the same breeding plant breeding wholesale, in order to ensure that the project used by the uniform size and shape of the forest, while ensuring ample quantity in stocking.
