Abstract
The invention relates to a construction method for waterlogging removing of an outdoor cable chute. The method comprises the steps of 1, setting the inner bottom face of the outdoor cable chute to be a slope and setting draining holes in the bottom of the side wall of the cable chute with lower slope side; 2, mounting water conduits on the draining holes, communicating the water conduits with the mounting positions of the draining holes, sleeving seal pads at the connecting positions between the water conduits and the draining holes and radially mounting screens in the water conduits; 3, connecting the other ends of the water conduits with an adjacent rainwater well by pipelines; and 4, mounting check valves on the connecting positions between the water conduits and the rainwater well in a hinging mode, wherein the check valves are opened when water flows flow from the water conduits to the rainwater well, otherwise, the check valves are closed. According to the method, after the water flows flow into the rainwater well, the check valves are rotated in a swinging mode to be reset to connect with openings of the water conduits in a pressing mode, so backflow of water flows is avoided, the possibility that external water permeates into the cable chute is also prevented due to the seal pads at the contacting positions between the draining holes and the water conduits and creeping of small animals such as mice can be prevented by the design of the screens in the water conduits.
Description
Technical field
The invention belongs to drainage and construction method field, especially a kind of for the construction method of outside cable ditch except ponding.
Background technology
Cable run is the important component part of urban power network, day by day perfect along with city function, and the requirement that urban aerial line enters ground is more and more outstanding.In recent years, newly-built road has all built conduit line, cable duct bank the same period, and the cable passable space network be jointly made up of them provides safeguard for urban development from now on.As long as the oversheath quality of cable is good, lays and also do not damage, in cable trench, a small amount of ponding can not have too large impact to cable, if but ponding is too much, cable long period of soaking, in water, can have a strong impact on Exterior cable insulating properties and operation stability, causes power grid accident.
At present, solve the method that the method for cable trench water collecting adopts suction pump usually, but suction pump cost is higher, seriously improve electric power and to speedily carry out rescue work cost, and submersible pump need can complete by multiple electric elements, subelement is comparatively accurate, once damage, maintenance cost is higher.
Through retrieval, find one section of patent document relevant to present patent application content, publication number is that 202545206U Chinese patent discloses a kind of device measuring cable trench water collecting.This utility model comprises water pumper, inductor and delay switch, and water pumper and inductor are cascaded, and delay switch is in parallel with inductor.The utility model has the advantage of: 1. can discharge moisture unnecessary in cable trench timely; 2. the existence of delay switch can ensure that the water in cable trench still can allow water pumper work a period of time again after inductor open circuit, extends working cycles.
Through contrast, there is relatively big difference in the technical scheme of above patent and present patent application.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, provide a kind of easy and simple to handle and effectively avoid cable be dipped in water for outside cable ditch except the construction method of ponding.
The present invention solves its technical problem and takes following technical scheme to realize:
For the construction method of outside cable ditch except ponding, the steps include:
(1) be set to domatic at outside cable ditch inner bottom surface, drain hole is set at the cable trench sidewall bottom of domatic lower side;
(2) on above-mentioned drain hole, aqueduct is installed, aqueduct is communicated with drain hole installation site, aqueduct and drain hole link position are set with sealing mat, radial installation screen cloth in aqueduct;
(3) be connected by pipeline between the aqueduct other end with contiguous catch-basin;
(4) cut with scissors on aqueduct and catch-basin link position and fill unilateral gate, current from penstock flow to catch-basin time, this unilateral gate open, otherwise, unilateral gate close.
And the (1) described domatic gradient of step is 0.3%.
And described unilateral gate rotation angle is 10 ~ 45 °.
And, the aqueduct mouth of pipe place contacted with described unilateral gate is provided with sealing rubber pad.
Advantage of the present invention and good effect are:
The present invention adopts and domatic cable trench current is carried out water conservancy diversion, when the water yield after water conservancy diversion arrives drain hole liquid level, namely current flow through aqueduct from drain hole and enter catch-basin, and the rotation angle of unilateral gate is drawn by calculating and repetition test, after current flow into catch-basin, unilateral gate rotation return crimps with the aqueduct mouth of pipe, thus avoid flow backwards, and the sealing mat on drain hole and drainage tube contact position also prevent the possibility that outside moisture infiltrates cable trench, in aqueduct, the design of screen cloth it also avoid climbing into of the toys such as mouse simultaneously, improve cable trench safety factor.
