On the morning of October 19, Li Shuming, member of the Party Leadership Group and deputy director of the State Forestry and Grassland Administration, Liu Keyong, deputy director of the Department of Planning and Finance, Haijiang, Changsha, deputy bureau of Beijing Municipal Bureau of Landscaping, Li Ziteng, deputy director of Pinggu District and other leaders visited the site to inspect the standardized forest fire prevention inspection station, underground silica honeycomb cistern and ground animal drinking water source demonstration project designed and constructed by Renchuang Technology Group.

Li Shuming, Deputy Director of the State Forestry and Grassland Administration, inspected the standardized forest fire prevention inspection station

In recent years, in order to improve the level of forest protection and fire prevention in mountain areas and protect ecological achievements, Beijing has gradually promoted the construction of forest fire prevention facilities and increased the coverage of forest fire prevention monitoring. The forest fire prevention pilot project in Yukou Town, Pinggu District includes a 19㎡ forest fire prevention inspection station with an effective volume of 100m³ Underground silica honeycomb fire reservoir, about 1600m³ The drinking water source for animals on the ground, and the seepage prevention project at the bottom of Liehuqiao River with an area of about 500m². Renchuang Science and Technology Group actively responded to the call of its superiors, continued construction on the premise of doing a good job in the prevention and control of COVID-19, and gave a satisfactory answer to the construction of forest fire prevention facilities.

During the leader's inspection, Zhang Xiaobin, assistant general manager of the marketing center of Renchuang Technology Group, was responsible for the whole explanation. The leaders who participated in the investigation introduced the construction of the forest fire prevention pilot project, demonstrated the fire resistance of the sand plastic composite material and the permeable water filtering, breathable and anti-seepage technology products independently developed by Renchuang, and checked the water quality of the effluent samples.

The leaders highly praised the application effect of the project through the demonstration of our technical products. The problem of no fire water in the forest area was solved by storing and purifying rainwater in the silica sand honeycomb underground pool, and the ecological environment in the forest area was improved; The seepage prevention project at the bottom of Liehuqiao River can solve the problem of water seepage and shortage of rivers and natural reservoirs in dry seasons, and the water stored in rivers and lakes can be used as fire water, landscape water and wildlife drinking water.

The standardized forest fire inspection station is a single storey building, with a building area of 19 ㎡ and a total floor area of 35 ㎡. It has a double slope roof, with cornice elevation of 3m and ridge elevation of 4.2m. The inspection station is equipped with offices, tool rooms, changing rooms and toilets (optional). Anti theft doors and windows are used. The main structure is assembled on site with sand plastic materials. The wall enclosure, roof and ground are all covered with sand plastic composite insulation board.

The sand plastic board is made of desert aeolian sand, which is a green and environment-friendly composite material product. It has natural ecology, environmental protection, no pollution, stable strength and good durability; Single layer cavity design, low dead weight, good sound insulation and heat preservation performance; The fire retardant performance grade shall reach Grade A; The construction is convenient, the special metal pendant is used, the structure is simple, the plate width is large, the installation speed is fast, the construction period is greatly shortened, the construction cost is saved, and the comprehensive cost is low.

The rainwater drainage ditch around the forest fire inspection station collects the rainwater on the roof. The collected rainwater first goes through the silica sand honeycomb filter to remove large particles of impurities and sediment, and then enters the silica sand honeycomb self purification tank for purification and long-term freshness preservation. The purified water quality is superior to the Class III surface water quality standard, which can meet the annual water demand of the forest fire inspection station.

—— Underground silica sand honeycomb fire reservoir ——

According to the functional requirements of the forest fire pool, the forest fire pool structure is designed to include two parts: the ground animal drinking pool and the underground silica honeycomb fire pool. As the main water storage unit, the underground silica sand honeycomb fire reservoir can directly take water from it when fire fighting is required. At the same time, the underground silica honeycomb fire water reservoir has the function of purifying water quality. When the water quality of the local animal drinking water reservoir deteriorates, the silica honeycomb fire water reservoir can purify the water body circularly; In dry season, when the evaporation loss of the ground fire pool is short of water, the underground silica honeycomb reservoir can replenish water to it; Before freezing in winter, the water stored in the ground animal drinking pool will be introduced into the silica sand honeycomb reservoir for storage and purification.

—— Drinking water source for ground animals ——

By reshaping the topography of the existing pond, create a drinking pool for animals to provide clean drinking water for wild animals. It is designed to connect the two existing ponds and make anti-seepage treatment at the bottom of the lake, and transform them into crescent shaped animal drinking pools. After transformation, the pool area is about 1600 m2, and the average water storage depth is 1m. The ground animal drinking pool adopts the unique permeability and seepage prevention technology of Renchuang, and uses the permeability and seepage prevention blanket and permeability and seepage prevention sand for seepage prevention treatment. It has the characteristics of permeability and impermeability, which can be both seepage prevention and breathable. On the premise of preventing water leakage loss, increase the dissolved oxygen content of water body to prevent water corruption.

Realistic map of drinking water source for ground animals

This project adheres to the scientific principle of giving priority to science and technology, adapting measures to local conditions, and standardizing standards. With cost saving as the basic starting point, it will build a standardized forest fire prevention inspection station, underground silica honeycomb cistern and ground animal drinking water source demonstration project that can operate reliably and meet the requirements. It will not only provide an innovative demonstration for forest protection and fire prevention, but also cultivate the forest ecosystem in Beijing, It also expands the new market prospects for the sand building achievements of Renchuang Group.
