Description

Lap joint method of soft joint type river channel of Hongqi river slope descending

Technical Field

Artificial river water conservancy project.

Background

The 'Hongqi river' is an artificial river in the demonstration stage of China, and along the south, east and north edges of Kanghai-Tibet plateau, Yalu-Tibet Bujiang, Yigong-Tibet Bujiang, Panlong-Tibet Bujiang, Langlan-Yangjiang, Jinshajiang and Minjiang are taken to supply water to the north and northwest ChinaThousand years of great work. The prior art is the technology of south-to-north water diversion open channel engineering, tunnel engineering, reservoir engineering and the like.

If the project of 'Red flag river' is started, the south, east and north edges of the Kanghai-Tibet plateau are the necessary places for the project, but the necessary places for the projectAnd also The earthquake moving zone of our country is the rising land of the extrusion platform of the Eurasian plate and the India plate(figure 12), this is a bottleneck problem which can not be avoided, and obviously is not feasible in terms of the prior art in the world, and the realization of the 'Hongqi river' project must be a way of scientific innovation.

Disclosure of Invention

Overall objective:

the soft joint type river pipeline at the front half section of the 'Hongqi river' realizes large slope drop, can realize the increase of the circulation of the river pipeline with the same cross section area, and can also reduce the engineering cost.

Secondly, through a 'soft joint type' river pipeline which is in Kangcang and transecting mountain seismic zones,can realize the natural movement along with the earthquake The water is not leaked and the water is supplied continuously.

Thirdly, the stability of the mountain is not interfered as much as possible.

The method mainly comprises the following steps:

with respect to the above-mentioned "one".

1. And a plurality of water-rolling and water-seepage dams are formed at the large turning part of the Brugu river in Yaluzang and the three-river parallel flow part crossing the mountain range in sequence in a mode that the upper part of an explosive mountain and the mountain stone freely roll down, so that the altitude of the initial front section of the 'Hongqi river' is raised.

2. In the original design route of' Hongqi riverFour 'by-pass' positionsNamely, the Chinese medicinal herb can ' bypass the Shaluri mountain, the Daxueshan ', the ' Dingqishan ', the ' Dingshan ' and ' the ' Minshan ',by taking siphon river pipeline wayThe route of the 'red flag river' is shortened, the gradient of a river pipeline is improved, and the probability of being damaged by falling rocks and debris flow is reduced.

3. According to the natural law of fluid motion in the pipeline, the soft joint type river pipeline between the water taking point and the water outlet point has the same flow quantity in the river pipeline no matter how the rising and falling gradient changes. When the fall between the water taking point and the water outlet point at the initial front section of the red flag river is increased,compared with the originally designed open channel river course with the slope of 2.1 ten thousandths, the river course is open The cross-sectional area of the canal and the river channel is N times of the cross-sectional area of the river channel。

A reservoir with a buffering function is arranged at the intersection of the water outlet point of the soft joint type river channel and the open channel river bed, and the potential energy of water ejected from the river channel with large slope is high.

Obviously, the scheme can reduce the diameter of the river pipeline, shorten the route of the 'Hongqi river' and reduce the total engineering cost.

The term "two" is used above.

In view of the 'soft joint type' river channel, the component structure and the lap joint mode thereof, if the displacement change in any direction in the 'limited' range of the river channel is caused by the displacement of the surface layer when earthquake happens, the river channel is not leaked, and the pier for supporting the river channel is still upright and still maintains the upright supporting state in the range of the gravity center supporting surface although the pier has displacement. Obviously, the scheme has the practicability of being applied to the earthquake active zone.

Regarding the above-mentioned "three".

Because the route of the large section in front of the Hongdan river is a sharply drawn young mountain, and the Eurasian plate and the Indian plate are continuously broken by extrusion and lifting, mountain collapse and debris flow are relatively easy to occur in the section, the scheme does not adopt the method for digging a mountain slope and leveling to build a river bed in the prior art, and the prior method intervenes the rest degree of the mountain. The scheme adopts a method of not interfering the mountain rest degree and giving way to rockfall and debris flow by using a low-bridge type. The 'Hongqi river' is a thousand years of major engineering.

As for the open channel riverbed at the rear section of the red flag river, a riverbed is built on a mountain slope with large slope, a method of digging mountains on site and leveling is not adopted, a stone yard is built on the top of a mountain of a construction site, stones are transported to the construction site in a sliding mode, and the riverbed is built in a stacking mode (figure 10). When the open channel riverbed at the rear section of the Hongdu river meets earthquake active zones, if the fund is allowed, the method of overlapping prefabricated parts by using an armor type soft joint (shown in figure 11) is preferably adopted, and the core technology of the method is the same as that of a soft joint type river pipeline (shown in figure 1).

Detailed Description

First, utilizeDam capable of rolling and seeping waterThe technology raises the water level of water intake from the source of the 'Hongqi river', and two rolling and seepage dams are reconstructed at the parallel flow position of the three rivers by using the same technology, so that the slope of the 'Hongqi river' is properly lifted, the flow rate of the 'soft joint type' river pipeline is increased, and the practicability of the 'soft joint type' river pipeline is improved.

1. From the proper place near the large turning of Yaluzang Bujiang and at the downstream of 2558 m high altitude, the mountain stone is freely rolled down from the mountain top to form a product with the width of several kilometers and the designed heightDam capable of rolling and seeping waterTo form a mountain lake with adjustable water quantity.

2. The elevation of the 'Hongqi river' from the Yalu Tibetan Bujiang river to the riverbed of the anger river is improved, the length of the originally designed riverway in the west of the anger river is actually shortened, and meanwhile, the originally designed tunnel crossing the transected mountain is lifted and displaced towards the north. The elevation of the tunnel bit taking also means that the length of the development tunnel is shortened.

3. Using the sameDam capable of rolling and seeping waterThe technology is characterized in that two rolling and water seepage dams with designed heights are respectively built in the billows and the Jinshajiang to form two intermodal lakes at the three rivers crossing the mountains, so that the length of the red flag river is shortened, the tunnel position can be shifted to the north, the length of the tunnel is reduced, and the flow rate of the soft articulated river pipeline is improved.

If the water source crossing the mountain at the three rivers and the parallel flow position can meet the water consumption of the red flag river on the premise of not influencing the water consumption of the downstream, the original design of taking water from the Bruguese river in Yalu Tibetan can be completely removed due to the adjustment of the inter-mountain lake at the three rivers and the parallel flow position, the length of the red flag river is greatly shortened, and the total cost is greatly reduced. Certainly, the engineering can be carried out in two stages, and the original design beginning section engineering is reserved for the next hundred years to be completed.

And secondly, prefabricating engineering of the 'soft joint type' river pipeline, which comprises prefabricating the river pipeline, the bridge, the pier and other components.

In China with the first high-speed rail technology world, the technology for prefabricating large steel reinforced cement components is mature.

The 'soft joint type' river pipeline is the most suitable component prefabricated part lapping method, which is not only for improving the efficiency, but also has more practicability because the 'soft joint type' method of the scheme is more suitable for preventing earthquake and ground surface displacement and is more suitable for natural rules compared with the rigid connection method in the prior art.

1. And (3) surveying specifically, acquiring technical parameters such as the height of each pier, the length and the model of a river pipeline and the like, and marking the parameters into a grade.

2. And constructing a large-scale component prefabricating field in sections, and simultaneously performing prefabrication, maintenance and label stock-in according to the file numbers. When the 'red flag river' is completed, all prefabricated sites are changed into the sites for spare component storage, maintenance and management departments.

3. And prefabricating the foundation engineering of each pier according to the archive parameters and the archive position, maintaining and sealing, and preparing materials such as sand and stone.

The above-mentioned first and second engineering processes are simultaneously implemented.

The 'soft joint type' river pipeline component prefabricated site is selected to be slightly higher than the actual height of a bridge, so that large prefabricated components can be conveniently conveyed to a river channel and lifted by utilizing a truss, and are hoisted to a large bridge transportation auxiliary and bridge lapping vehicle and conveyed to a construction site for lapping process.

And thirdly, lapping the river pipeline in a soft joint mode.

1. Before a new section of river pipeline is lapped, the rubber ring is sleeved, and a large bridge transport and bridge lapping vehicle is abutted and lapped with the positioned river pipeline to be positioned.

2. And then, injecting soft organic foam from the inside and the outside of the river channel to the gaps between the front part and the rear part of the rubber ring which are overlapped in place, and then sealing.

3. If the 'soft joint type' river pipeline component is in a bridge pipeline integrated mode, the lap joint method of the river pipeline is the same as the prior art of the high-speed rail viaduct.

4. If the 'soft joint type' river pipeline member is in a bridge and pipeline separation mode. If a high-speed rail viaduct is built, firstly, the bridge is lapped, and then, a river pipeline lapping process is carried out on the roadbed at the upper part of the river pipeline by using a large bridge transportation and bridge lapping vehicle.

5. For a single river pipeline tunnel, pipeline lapping can be sequentially carried out in a backset mode by a large-scale bridge transportation and bridge lapping vehicle.

6. For river pipelines and highway tunnels, the support tables of the highway components are arranged on the mountains on two sides of the tunnels and can be respectively and sequentially overlapped according to the lengths of the river pipelines and the highway components.

Fourthly, open canal engineering.

1. An artificial lake is built at the intersection of the outlet of the 'soft articulated' river pipeline component and the open river channel and is used as an energy buffer storage capacity for flushing high-potential energy flowing water from the 'soft articulated' river pipeline.

2. When the open canal project passes through a mountain with steep slope, the riverbed can not be leveled by a method of digging a hill, but a method of building stones is applied to ensure that the stability of the mountain is not interfered as much as possible (figure 10).

3. In the open canal engineering stone exploitation stope, the mountain above which the engineering is located, the mountain top where the stone is conveniently transported in a sliding way or the mountain body where the stone is suddenly and easily collapsed are selected, so that the stone is easily exploited and hidden troubles are eliminated (figure 10).

4. The cross-sectional size of the open canal is calculated by the person skilled in the art according to the flow rate of the "soft-jointed" river channel, and of course, a safety factor is added.

5. If the open canal engineering meets earthquake active zones, if the capital permits, a 'house tile type' open canal component lap joint prefabricated component method is preferably adopted (figure 11 WSD).

The core technology of the 'tile type' open channel member is the same as that of the 'soft joint type' river pipeline.
