Description
Technical Field
The invention relates to a reinforced pile structure technology for anti-skid of a power transmission line tower, in particular to an anti-skid pile structure system for electrified treatment of power transmission line tower landslide.
Background
The tower of the power transmission line in areas with easily slippery rock and soil such as strong weathered granite is easy to slide in rainy seasons, and the safe operation of the power transmission line is seriously threatened. For a power transmission line tower landslide, the most commonly used treatment scheme is as follows: lane change, slope treatment and the like; although the line change is safe and reliable, besides a stable tower site, power is required to be cut off during construction, and the slope surface treatment can only treat shallow landslide, so that the landslide slope surface treatment effect is not ideal once the depth of a sliding surface is large. The current anti-slide pile is mainly used for reservoir dam landslide control, highway landslide control and the like, and generally plays a role in stabilizing a part (or a whole) of a sliding soil body.
Disclosure of Invention
The invention aims to provide an anti-slide pile system for electrified treatment of a power transmission line tower landslide, which is mainly used for stabilizing a tower foundation by carrying out anti-slide treatment without power failure and can solve the problem of reinforcement of the power failure and displacement condition of the electric tower. When a particularly important power transmission line cannot cut power and needs to treat a tower landslide, the invention adopts an electrified construction mode, namely, the tower is electrified and reinforced by driving an anti-slide pile nearby the tower. The anti-slide pile utilizes the self bending resistance and the lateral resistance of the underground stable rock and soil layer, and the anti-slide pile and the original tower foundation are connected into a whole through the connecting beam, so that stable support is provided for the tower foundation, and the effects of resisting landslide and stabilizing the tower are achieved. The design and the pile arrangement of the anti-slide piles are flexible, and the principle is clear; by excavating the pile hole, the geological condition can be directly observed, the rechecking and verification of the design are facilitated, and the construction process is simple.
To achieve the object, the invention provides:
the invention discloses an anti-slip structure for electrified management of a power transmission line tower landslide, which is characterized in that: comprises eight anti-slide piles (1), a connecting beam (2) for connecting the anti-slide piles with a tower foundation (4), and a foundation upright post well type reinforcing ring (3). Four anti-slide piles (1) are respectively arranged on two sides of an electric tower foundation (4) side by side along a horizontal landslide direction, the four anti-slide piles (1A) on the outer side are respectively connected through vertical connecting beams (2A), and the four anti-slide piles (1B) on the inner side are mutually connected after the foundation is anchored through the vertical connecting beams (2B); each row of anti-skid piles are connected in series by a transverse connecting beam (2C), and four foundations are connected by a transverse connecting beam (2D) and then are lapped on a vertical connecting beam (2A), so that the four foundations are connected and combined into a nine-format integral structure system; a well type reinforcing ring (3) is arranged on the upright post of the electric tower foundation (4) to perform sleeve joint reinforcement on the upright post of the electric tower foundation (4); the electric tower foundation (4) is connected with the connecting beam (2), and the bottom plate of the electric tower foundation (4) is connected with the well type reinforcing ring (3) in a reinforcing manner by adopting a bar planting technology.
Compared with the prior art, the invention has the beneficial effects that:
(1) While conventional slide pile systems are typically used to stabilize a mass of landslide soil (or soil block) so that a built-up (constructed) building on the landslide mass is endangered by the landslide, the present invention aims to directly fix a landslide-endangered electric tower foundation onto the slide pile system, and the engineering objective is directly effective and in one step.
(2) The eight anti-slide piles are connected with the foundation through the connecting beams to form a nine-format integral structure system, and compared with the original anti-slide structure system, the anti-slide pile structure system is more reasonable in arrangement, the effect of resisting landslide hazard is enhanced, and the reliability of the power transmission tower in a special environment is more powerfully ensured.
(3) The invention adopts the well type reinforcing ring to reinforce the foundation at the joint of the original electric tower foundation and the anti-slide pile connecting beam, adopts the reinforcement planting technology to reinforce the connection, and is verified by engineering examples, the method is simple and effective and is convenient to implement.
(4) The invention can carry out landslide treatment on the electric tower under the condition of no power failure and has good economic and social benefits.

Detailed description of the preferred embodiments
The invention will now be described in further detail with reference to the drawings and examples of embodiments.
As shown in fig. 1, the invention is a slip-resistant structure for electrified management of a power transmission line tower landslide, which is characterized in that: comprises eight anti-slide piles (1), a connecting beam (2) for connecting the anti-slide piles with a tower foundation (4), and a foundation upright post well type reinforcing ring (3). Four anti-slide piles (1) are respectively arranged on two sides of an electric tower foundation (4) side by side along a horizontal landslide direction, the four anti-slide piles (1A) on the outer side are respectively connected through vertical connecting beams (2A), and the four anti-slide piles (1B) on the inner side are mutually connected after the foundation is anchored through the vertical connecting beams (2B); each row of anti-skid piles are connected in series by a transverse connecting beam (2C), and four foundations are connected by a transverse connecting beam (2D) and then are lapped on a vertical connecting beam (2A), so that the four foundations are connected and combined into a nine-format integral structure system; a well type reinforcing ring (3) is arranged on the upright post of the electric tower foundation (4) to perform sleeve joint reinforcement on the upright post of the electric tower foundation (4); the electric tower foundation (4) is connected with the connecting beam (2), and the bottom plate of the electric tower foundation (4) is connected with the well type reinforcing ring (3) in a reinforcing manner by adopting a bar planting technology.
The construction method of the invention is that before the construction is started, the temporary stay wire is led out from the special positions (sixteen nodes are black points) of the tower body and is connected with the lower stay wire disc, thereby fixing the electric tower.
As shown in fig. 1, which is a schematic view of the pile-beam planar arrangement of the present invention. After the power transmission tower is effectively fixed, pile foundation construction is started. When pile holes are excavated, feasible drainage measures and illumination measures are needed. If construction is performed in rainy season, measures are added to prevent rainwater from entering pile holes. In the process of excavation, irregular air supply to the holes is preferably adopted for the pile holes which are possibly lack of oxygen. And the protection wall is cast while digging the hole. When the pile bottom needs to be drilled, the rock surface is blasted and cleaned by rock drilling, shallow hole small-dosage blasting and wet operation are adopted for drilling. The earth dug by the digging hole needs to be transported away in time, and the earth cannot be piled up in one meter of the four weeks of the hole. When the steel bar is dug to the designed elevation, the depth of the sliding surface needs to be checked again, so that the position of the steel bar is determined again. When the pile hole reaches the designed depth, the bottom of the hole is cleaned, the bearing layer at the pile end is strictly forbidden to be immersed by underground water, and after the pile hole is checked and accepted by geology personnel, the pile body is finished by adopting one-time continuous pouring of concrete.
In order to ensure safety, the construction of the slide-resistant piles is firstly completed and the connection of the slide-resistant piles and the tower foundation is carried out after the completion of the connection, and the construction is carried out according to a certain sequence, as shown in figure 2, the construction sequence of the connecting beam can be S-1- & gt S-2- & gt S-3- & gt S-4, and the construction of the next stage is allowed after the backfill is constructed in each stage. The reinforcing steel bars of the well type connecting reinforcing ring are reserved in the S-1 stage construction. Meanwhile, vertical construction joints are reserved strictly according to the requirements of construction joint reserved drawings. When the construction joint is constructed next time, after necessary cleaning roughening measures are carried out on the construction joint, cement mortar with the same components as concrete is paved at the construction joint, and then pouring and tamping are carried out.
As shown in fig. 1, the tie beam is connected to the slide piles and the foundation columns. The beam and the foundation upright post are connected by a bar planting method, and the concrete scheme is as follows: firstly, all concrete protective layers at the joints of the beams and the foundation upright posts are removed, and the longitudinal reinforcing steel bars of the foundation upright posts are exposed by roughening. And then the foundation protective cap is opened, the positions of the footing bolts are confirmed, the original positions of the steel bars are properly adjusted, holes are drilled on the foundation upright posts, the steel bars of the original upright posts and the foundation bolts are staggered for connection (construction is carried out according to the related requirements of a steel bar planting method), and the protective cap is supplemented.
As a further scheme of the invention: the included angle between the temporary stay wire and the ground is 30-45 degrees. The single GJ-100 is adopted for wire drawing, LP1.2 is adopted for wire drawing disc, and the burial depth is 2.5m. Since for live operation care is taken to ensure that the distance between the pull wire and the nearest wire is not less than 1.5m and other necessary safety measures are taken.
The foregoing description is only of the preferred embodiments of the present invention, and is not intended to limit the invention, but any minor modifications, equivalents, and improvements made to the above embodiments according to the technical principles of the present invention should be included in the scope of the technical solutions of the present invention.
