Assembly type non-pressure culvert for novel reverse construction method and construction method thereof
It is an upside-down and prefabricated technology, which is applied in artificial islands, water conservancy projects, infrastructure projects, etc. It can solve the unfavorable future development direction of green buildings, the backfill soil on both sides of the culvert is not easy to compact, and the overall stability of the structure is poor. Prevention of social instability, reduction of relocation and soil erosion, and strong overall stability

Problems solved by technology
In practical application, this type of traditional culvert has disadvantages such as large excavation volume, great influence by geological conditions (most of which need to deal with the foundation), poor overall structural stability, difficult compaction of backfill soil on both sides of the culvert, and uncontrollable settlement of the main body.
At the same time, the construction operation has a greater impact on the surrounding environment, the construction period is longer, and the construction cost is higher
Now this kind of culvert structure type and construction method has been used for many years in the field of engineering construction in my country, which is not conducive to the national industrial policy and the future development direction of green buildings, and is at the end of the life cycle

Embodiment Construction
[0020] For the convenience of description, spatially relative terms may be used here, such as "on ...", "over ...", "on the surface of ...", "above", etc., to describe the The spatial positional relationship between one device or feature shown and other devices or features. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, devices described as "above" or "above" other devices or configurations would then be oriented "beneath" or "above" the other devices or configurations. under other devices or configurations". Thus, the exemplary term "above" can encompass both an orientation of "above" and "beneath". The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptions used herein interpreted accordingly.

The invention relates to the technical field of building construction, in particular to an assembly type non-pressure culvert for a novel reverse construction method. The culvert comprises prestressed precast pile side walls, an upper top plate and a lower bottom plate, the prestressed precast pile side walls are composed of precast piles arranged side by side, pile head steel plates are pre-buried in pile heads of the precast piles, and the pile head steel plates are welded to stressed steel bars in the upper top plate. Key grooves are formed in the lower portions of the precast piles, embedded steel plates are arranged in the key grooves, the embedded steel plates are connected with stressed steel bars in the precast piles, and mechanical connecting joints are reserved on the embedded steel plates and connected with the stressed steel bars of the bottom plate. The structure is clear in stress, high in overall stability, free of foundation treatment and small in settling volume.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a novel upside-down fabricated non-pressure culvert and a construction method thereof. Background technique [0002] In recent years, with the growing strength of my country's comprehensive national strength and the government's increasing investment in various infrastructures and important building materials research and development, my country's municipal and water conservancy industries have achieved rapid development by leaps and bounds. Among them, culvert, as a commonly used structural type in municipal highways, railway projects and water conservancy projects, occupies a large proportion in engineering construction. According to relevant statistics, the number of culvert projects in my country accounts for about 60% to 70% of the total number of infrastructure constructions, with an average of 1 to 3 per kilometer in plain areas and 4 to 6 per kilometer in mo...
