3. Supplement the production capacity of 300,000 tons/year!
Three, sand and gravel aggregate industry this week dynamic
1, annual output of 9 million tons! The project is located in Xin'an Town, Linli County, mining limestone for ordinary construction, with a designed mining scale of 9 million tons per year, a service life of 18.2
years and an annual output of 4.65 million tons! A mining right in Jinhua was successfully sold! The resource reserve of the mine is 46.16 million tons, the design scale is 4.65 million tons/year, the transfer period is 11 years, and the final transfer period is 4 years by Zhejiang Ruixuan Mining Co., Ltd. In addition, the mining right also includes the policy processing fee of 3.3
million cubic meters/year! Located in Panlong Village, Shizi Town, Qichun County, the mine is mining granite for construction. Within the mining area, there are 12.098 million cubic meters of granite ore resources for construction, including 8.058 million cubic meters of controlled resources and 1 million cubic meters of production scale per year.
4. Comments on
the dynamics of the concrete industry this week 1. The pouring of the inverted arch of the first slab of Shantou Bay Tunnel was completed
on February 20. The Guangzhou-Macao Port Railway Project, a provincial and municipal key project undertaken by the 14th Bureau of China Railway, has received another good news-the completion of the pouring of the first plate inverted arch of Shantou Bay Tunnel, a key and difficult control project, which has pressed the "acceleration key" for the project to resume production in an all-round way. This is another important node of the project since the successful operation of the exit of Shantou Bay Tunnel on February 13. At present, the project department adopts the combination of mining method, shield method and open-cut method to set up inclined shaft, shield shaft and multiple working faces at the same time. The construction of two super-large bridges and Shantou Bay Tunnel along the Guangzhou-Macao Port Railway Project is in full swing. Among them, 40 bearing platforms have been completed for the extra-large bridge across Leiguang Avenue, accounting for 32% of the total; 26 piers and abutments have been completed, accounting for 20% of the total; the No.2 inclined shaft of Shantou Bay Tunnel has been completed 76.1% of the total, and the No.1 inclined shaft has been completed 10.2% of the total
! The document further clarifies the qualification requirements for the establishment of the mixing station, the application for the establishment of the station, the confirmation and approval process, and the identification of production capacity. Production enterprises are required to carry out station construction and production capacity construction in strict accordance with the requirements, establish and improve management system, product quality assurance system and product quality tracking system, and implement relevant laws, regulations and technical standards. It is not allowed to build first without approval, "build large without approval", use first without approval, and falsify in the process of station construction and production and operation. The first prefabricated pier of a fully fabricated bridge
in Hubei Province was successfully
hoisted. Recently, the first prefabricated pier of a fully fabricated bridge in Hubei Province was successfully hoisted, and the bridge construction entered a new stage of "building blocks" construction. The project adopts the general contracting management mode to build a fully assembled intelligent prefabricated component yard, and completes 30% of the bridge substructure construction through factory prefabrication, on-site assembly and other procedures, including 52 prefabricated piers and 28 capping beams. Compared with the traditional cast-in-place scheme of conventional piers, the temporary road-occupying range is 16 meters and the time is 6 months, the full-assembly construction technology greatly shortens the construction period, the temporary road-occupying range is only 14 meters and the time is only 3 months, and the temporary road-occupying time is reduced by 50% during the construction period. The national concrete price index closed at 139.76 points
this week, up 0.01% from the previous month and down 8 from the previous year. Regionally, the price of local concrete in Guangxi market increased by 5 yuan per square meter. The price of local concrete in Hebei market was reduced by 5 yuan per square meter, while the price of concrete in other provinces and cities in China remained basically stable. In
the next ten days, the precipitation in the southern region will continue to be less. There will be 10 to 25 millimeters of precipitation in the southeastern part of the Xizang, the western Sichuan Plateau, the eastern part of the southwest, and the western part of the south of the Yangtze River. There will be more than 50 millimeters of precipitation in the southeastern part of the Xizang, Guizhou, and other places. In addition, there will be 3 to 10 millimeters of accumulated precipitation in the northwestern and southern parts of Xinjiang, the southern part of Qinghai, and the northern part of Northeast China. The precipitation in Huanghuai, Jianghuai, Jiangnan and the southern part of central and southern China is 5 to 80% less, the eastern part of Southwest China and the Qinghai-Xizang Plateau is 5 to 70% more, and the precipitation in most other parts of China is close to perennial. In terms of temperature, the average temperature in southern and Eastern Xinjiang, northwestern Xizang, Eastern Northwest China, North China, northeastern China, Huanghuai, Jianghan and northwestern Jiangnan is 1 to 3 degrees higher than that in the same period of the year, while the temperature in most other parts of China is close to that in the same period of the year, among which the temperature in Eastern Xizang and western Sichuan Plateau is 1 to 3 degrees lower.
To sum up, the weather in most parts of the country will be fine next week, and the construction index will rise further. Recently, the personnel arrival rate of construction projects has increased significantly, and the downstream construction demand has increased compared with the previous period, but some projects still have a shortage of funds, which drags down the growth of concrete demand. In terms of cost, the upstream aggregate price still shows a downward trend, but many cement enterprises try to push up the quotation, and the follow-up cost support or slight improvement. On the whole, the demand for concrete market will continue to rise next week, and the price trend will be mainly stable, with a slight adjustment in some areas.
