Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1-4 illustrate front, left, top and bottom views, respectively, of a transverse drain pipe securement device according to the present invention. As can be seen in fig. 1 to 4, a tunnel transverse drain pipe fixing device includes: the top surface is a rectangular steel plate, the left side surface and the right side surface are arc-shaped steel plates and are respectively fixedly connected with the long sides of the rectangular steel plate, and the front side surface is fixedly connected with the short sides of the rectangular steel plate; the top surface, the front side surface, the left side surface and the right side surface are enclosed to form a semi-closed three-dimensional fan-shaped structure. The front side surface is used as a first positioning piece, and a second positioning piece is arranged in the fixing device; referring to fig. 2, the first positioning member and the second positioning member divide the inner space of the fixing device into an upper portion and a lower portion. It will be appreciated by those skilled in the art that in order to ensure a flat concrete casting surface, the lower half of the fixture should be open, with the arcuate surfaces mating with the concrete wall, and the lower half of the front face open.
As shown in fig. 2, a transverse drain pipe clamping groove is arranged at the lower edge of the first positioning piece, and the clamping groove is in an upward convex arc shape matched with the shape of the transverse drain pipe; the second positioning piece is fixedly connected with the left side face and the right side face respectively and is provided with an arc-shaped section which is matched with the shape of the transverse drainage pipe and protrudes upwards. The convex arc section that makes progress can play fine limiting displacement. When concrete is poured and filled, the positioning piece can fix the position of the transverse water guide pipe, and the transverse water guide pipe is prevented from being deformed or displaced due to the impact of the concrete. Therefore, after concrete pouring is finished, the smoothness of the horizontal water guide pipeline type can be still ensured, and the joints of the longitudinal and horizontal drainage facilities are firm and are not staggered.
As shown in fig. 3, an inspection hole is provided on the top surface, through which the position of the lateral drain pipe can be corrected; the length and the width of the fixing device are respectively equal to those of the rectangular steel plate, the height of the fixing device is equal to that of the arc-shaped steel plate, and the arc-shaped edge of the arc-shaped steel plate is matched with the concrete side wall.

A preferred embodiment of the present invention is that the length and width of the rectangular steel plate are determined according to the length and width of the lateral drain pipe, respectively, and actual construction requirements. As will be appreciated by those skilled in the art, the fixing device is required to cover the transverse drain pipe for fixing the position of the transverse drain pipe when in use, so that the minimum width of the rectangular steel plate cannot be smaller than the diameter of the transverse drain pipe; in addition, when the fixing device is used, the fixing device needs to be placed between two adjacent inverted arch reinforcing bars, so that the arc surface of the fixing device is attached to the concrete side wall of the tunnel, and therefore the maximum width of the rectangular steel plate cannot exceed the distance between the two adjacent inverted arch reinforcing bars. The length of the rectangular steel plate is suitable for fixing the transverse drainage pipeline type and fixing the tee joint at the joint of the longitudinal and transverse drainage facilities. That is to say, the length of the rectangular steel plate cannot be too short, otherwise, the limiting force applied to the transverse water guide pipe by the fixing device cannot sufficiently offset the impact force on the transverse water guide pipe during concrete pouring, and therefore the purpose of the invention cannot be achieved; the rectangular steel plate also cannot be too long in length, otherwise, the lifting is difficult on one hand, and the manufacturing cost is increased on the other hand.
The invention has a preferred embodiment that the arc-shaped edge of the arc-shaped steel plate is matched with the concrete side wall, the size of the arc is determined according to the diameter of the side wall, and the height of the arc-shaped steel plate is determined according to the design elevation and the actual construction requirement.

A preferred embodiment of the invention is where the deployment position of the spacer does not block the view of the access opening.
One preferred embodiment of the invention is that the fixing device of the transverse drain pipe is connected and fixed by welding, bolts, pins and/or riveting among the assembly elements.
In a preferred embodiment of the present invention, as shown in fig. 5, more than one reinforcing holes are respectively formed on the left side surface and the right side surface of the fixing device to serve as connection portions of the fixing device and the two side inverted arches, and the fixing device and the two side inverted arches are detachably connected through stirrups.
Fig. 6 is a construction method of a tunnel transverse drain pipe fixing device according to the present invention, as shown in fig. 6, the construction method including the steps of:
step 1, designing and manufacturing steps:
(1) shape and size design: determining the shape and the size of the transverse drain pipe fixing device according to the radius of the concrete side wall and the size of the transverse drain pipe;
(2) blanking: selecting a steel plate and a steel bar material with enough rigidity, wherein the surface of the steel plate is flat and has no rust and rust;
(3) and (3) processing and storing: modifying the preliminarily processed clamping groove, and carrying and properly storing the processed clamping groove;
step 2. mounting step
(4) Installing a transverse drain pipe: measuring and positioning the elevation mileage and the gradient of the transverse drain pipe, calibrating the position of the transverse drain pipe and installing the transverse drain pipe;
(5) pretreatment of a contact surface: polishing the contact surface of the transverse drain pipe fixing device and the concrete side wall;
(6) installing a transverse drain pipe fixing device: fixing a transverse drain pipe fixing device on the bound inverted arch reinforcing steel bars, and correcting the position to enable the transverse drain pipe fixing device to be matched with the transverse drain pipe in an attaching mode;
(7) the fixing device is hermetically connected with two ends of the transverse drain pipe;
step 3, pouring: and pouring concrete, after the concrete is initially set, slightly lifting the clamping groove, and entering the next construction cycle.
In a preferred embodiment of the present invention, the steel plate has sufficient rigidity to prevent deformation during use, and the steel plate with a thickness of not more than 3mm is selected, and the steel plate with a thickness of more than 3mm increases the construction difficulty. Before the installation, polish the contact surface of horizontal drain pipe fixing device and concrete side wall with the emery wheel, guarantee that fixing device's arcwall face and side wall concrete face can the abundant contact, guarantee that fixing device installs firmly. The non-woven geotextile is adopted to fill the gap between the transverse drain pipe and the fixing device, so that the transverse drain pipe and the fixing device can be connected in a sealing manner, and the transverse drain pipe is prevented from being blocked due to the fact that the transverse drain pipe is wrapped by pouring concrete.
In a preferred embodiment of the present invention, referring to fig. 5 (a) and (b), more than one reinforcing hole is respectively arranged on the left side surface and the right side surface of the fixing device to serve as a connecting portion of the fixing device and the two side inverted arches. After the fixing device is installed in place, the fixing device is detachably connected with the left and right inverted arches through stirrups, so that the horizontal and/or vertical positions of the fixing device can be effectively controlled to be kept unchanged. And after the concrete pouring is finished, removing the stirrups and lifting the fixing device. The effect of the stirrup can be achieved by a person skilled in the art by replacing the stirrup with a similar device.
In a preferred embodiment of the invention, the steel plate surface is coated with a release agent for lubrication to reduce adhesion to concrete. The release agent may be selected from the prior art known in the art and will not be described in detail herein.
In a preferred embodiment of the invention, after a construction run is completed, the concrete is tested for initial set strength and then the fixture is lifted, immediately ground and stored properly to avoid collision and contamination.
In a preferred embodiment of the invention, the transverse drain pipe is made of HDPE double-wall corrugated pipes with the diameter of 100-. The omega-shaped spring drainage pipe is only adopted in places with serious water leakage in principle, the V-level surrounding rocks of the hidden tunnel are arranged at intervals of 4-5m, and the III-level surrounding rocks and the IV-level surrounding rocks of the open tunnel are arranged at intervals of 10 m. The drainage gradient of the transverse drainage pipe is 5 percent.
Further, the most difficult construction of the fixing device is that it is difficult to secure the position of the fixing device during the concrete pouring process, and therefore, after the fixing device is installed in place, the construction worker should take quality control measures to prevent the fixing device from being deformed by displacement during the concrete pouring process, and then check the fixing device to confirm that the installation position of the fixing device meets the construction requirements.
Furthermore, before the tunnel drainage system is constructed, a measurer checks the clearance of the primary support section of the tunnel, and then constructs the annular, longitudinal and transverse drainage pipes and the geotextile waterproof boards according to the design file and the requirements of relevant specifications.
The fixing device for the transverse drainage pipe is arranged, so that two ends of the transverse drainage pipe can be protected to the maximum extent, and the smooth line shape of the transverse drainage pipe is ensured. The vertical and horizontal drainage pipes can meet the requirements of line shape and gradient after being connected through the tee joint.
Compared with the traditional process, the installation time of the longitudinal and transverse water discharge pipes and the tee joint can be saved by more than 24%. When the transverse drain pipe is installed in the traditional process, the fixing device is not adopted, and only the two ends of the transverse drain pipe are wrapped and processed by the geotextile, so that the connection quality cannot be ensured, and extra engineering quantity is increased when the longitudinal drain pipe is installed subsequently. When the fixing device is adopted and not adopted, the installation time of the fixing device, the installation time of the transverse drainage pipe, the installation time of the longitudinal drainage pipe, the transverse drainage pipe and the tee joint are shown in a table 1. The following table installation times are the installation times of each pair of facilities (two fixtures, two tees), and the installation times of 5 pairs of facilities are continuously investigated and averaged.
TABLE 1 time comparison of vertical and horizontal drainage pipes installed by fixing device
As can be seen from Table 1, the installation time of the transverse drain pipe is 18min when the fixing device is adopted and the fixing device is not adopted, and the installation time of the pair of fixing devices is 8 min. When the fixing device is not adopted, before the longitudinal and transverse drainage pipes are connected with the tee joint, the concrete surface is leveled, and the installation time of the pair of longitudinal and transverse drainage pipes and the tee joint is 32 min.
Install a pair of horizontal drain pipe, indulge, horizontal drain pipe and tee bend erection time:
a clamping groove is adopted: 8+18+12=38min
No clamping groove is adopted: 0+18+32=50min
Time saving when the card slot is adopted: (50-38)/50 x 100% =24%
Therefore, after the fixing device is used, 24% of longitudinal and transverse drainage facility installation time is saved, the fixing device can be reused, and the efficiency is considerable in long-term benefit.
The above-described embodiments should not be construed as limiting the scope of the invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions can occur, depending on design requirements and other factors. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
