Description
Technical field
The utility model belongs to the technical field of major diameter running water pipe security protection construction in subway construction, specifically a kind of major diameter running water pipe safety protection structure.
Background technology
In subway accessory structure work progress, there is the facility such as cable, running water pipe above accessory structure, accessory structure overlying soil need excavate under the prerequisite of the installation security protection such as running water pipe, and excavation soil layer laggard row accessory structure is concrete builds.In recent years, along with developing rapidly of China's urban construction, increasing city starts to build subway, conveniently citizens' activities, subway accessory structure must pass through the major diameter permanent facility such as pipe from the beginning, major diameter running water pipe all supplies the living water use of a large amount of resident of Yingcheng City usually, acts on extremely important.For the security protection of the running water pipe of conventionally form, temporary structure is adopted to protect it.But for passing through the situation of major diameter running water pipe, in order to meet the indexs such as Clearance requirement, comfort level, blind person's passage, economy, distance between accessory structure design end face and water pipe bottom surface is very little, be about 15cm ~ 30cm, the construction of accessory structure is according to the method for routine, the crossbeam of temporary structure has stretched in accessory structure, cause accessory structure reinforcing bar binding difficulty even cannot colligation, and destroy the stressed of accessory structure, and remove and face structure is cumbersome, economic benefit is not good deficiency and the technical requirements that can not meet related specifications.
Summary of the invention
The utility model, in order to solve the problem, provides a kind of major diameter running water pipe safety protection structure especially.
The utility model takes following technical scheme: a kind of major diameter running water pipe safety protection structure, comprise the concrete plate washer being arranged on water pipe both sides, plain concrete is supported with on the downside of water pipe, described concrete plate washer and plain concrete are arranged on crossbeam, be provided with some columns on the downside of crossbeam, upright supports is on concrete pipe base.
Described crossbeam is the partial panels of subway accessory structure, and crossbeam is placed on column by temporary support (12).
Described column adopts the lattice post of angle steel or channel-section steel composition, and periphery is provided with lacing or batten plate.
Described pile foundation comprises concrete and reinforcing cage, and column to insert in reinforcing cage and is welded to connect with it.
The column tie-rod of cross shaped head is provided with between two adjacent root posts.
The utility model has following effect: construction technology is simple, practical value is high; result of use is good; can sufficient related specifications require and the demand of water for city's residential use; neither need the absolute altitude reducing access top board; comfort of passenger meets the demands; do not need again to remove transverse and longitudinal concrete beam, the man-made further destroy of water pipe protection system can not be caused.Improve operating efficiency, shorten the duration, reduce construction cost, achieve good economic benefit.

Detailed description of the invention
As shown in Figure 3,4, a kind of major diameter running water pipe safety protection structure, comprise the concrete plate washer 9 being arranged on water pipe 6 both sides, plain concrete 10 is supported with on the downside of water pipe 6, described concrete plate washer 9 and plain concrete 10 are arranged on crossbeam 11, be provided with some columns 13 on the downside of crossbeam 11, column 13 is supported on concrete pipe base 14.
Described crossbeam 11 is the partial panels of subway accessory structure, and crossbeam 11 is placed on column 13 by temporary support 12.
Described column 13 adopts the lattice post of angle steel or channel-section steel composition, and periphery is provided with lacing or batten plate.
Described pile foundation 14 comprises concrete and reinforcing cage, and column 13 to insert in reinforcing cage and is welded to connect with it.
The column tie-rod 16 of cross shaped head is provided with between two adjacent root posts 13.
Specific construction step is as follows:
1) row adds structure construction;
measure of pile position: adopt total powerstation accurately to measure before drilled pile construction, measure drilled pile position.
exploratory trench excavates: before Spiral digging machine creeps into, and must put position excavation exploratory trench, verify underground utilities and obstruction to stake.Exploratory trench can excavate by single-point, also can excavate integrally trial trench.
rig is installed: after driller insertion, leveling support, guarantees that bit central and casing center are on a plumb line, with the centrical deviation in hole within specification allowed band.
bore operation: after spudding in, aims at boring by rig leveling, aligns stake position, confirms that room can start to creep into after errorless.
column and fabrication of reinforcing cage: the making carrying out reinforcing cage and column while drilled pile construction, after on-the-spot reinforcing cage and column machine, undertaken being welded to connect 18 by main for pile foundation muscle 17 and column,
pile foundation concreting: after reinforcing cage and column are transferred, builds pile foundation concrete.
2), soil excavation;
Adopt the step excavation method method of carrying out out, the method realizing its process is as follows:
The first step, hand excavation, to running water pipe tip position 19, calculates 21 absolute altitudes at the bottom of running water pipe pipe with this, specifies absolute altitude at the bottom of pipe and the high relation of structure roof top mark;
Second step, to be excavated at the bottom of running water pipe 21, the gradient is 1:1, and side slope adopts C20 microlith sprayed mortar 20 to reinforce, and bottom running water pipe, 21 excavation lines are 0.5m apart from crossbeam 11 edges;
3rd step, bottom running water pipe, 21 excavation boundary lines are excavated to accessory structure top board 3 end 5cm downward vertically, if there is joint in running water pipe 6, to topotype of constructing after construction after the reinforcing of water pipe head place employing steel plate anchor ear, colligation crossbeam reinforcing bar, build crossbeam, water pipe both sides concrete baffle plate, have plain concrete 10 to backfill in baffle plate 9 position;
4th step, progressively excavation is pushed ahead, and advance distance is center to center distance between framed bent.
