Abstract
The utility model relates to a concrete pouring and head sealing device through pump pipes, which comprises a steel mould jumbo formwork surface, a first pump pipe and a second pump pipe, wherein the steel mould jumbo formwork surface is provided with the first pump pipe and the second pump pipe; the first pump pipe and the second pump pipe are respectively positioned inside and outside the steel mould jumbo formwork surface; a reinforcing steel plate is arranged inside the steel mould jumbo formwork surface; a separation steel plate is arranged between the first pump pipe and the outside of the steel mould jumbo formwork surface; a long bolt passes through the first pump pipe, the separation steel plate, the steel mould jumbo formwork surface, the reinforcing steel plate and the second pump pipe to ensure that the first pump pipe, the separation steel plate, the steel mould jumbo formwork surface, the reinforcing steel plate and the second pump pipe are fixedly connected; and the second pump pipe is fixedly connected with the reinforcing steel plate through a bolt. After the concrete pouring and head sealing device provided by the utility model completes pouring, the pump pipe outside the steel mould jumbo formwork surface is removed. The concrete pouring and head sealing device is very suitable for pouring a top arch in the tunnel lining concrete construction.
Description
Technical field
The utility model relates to a kind of power station construction work concrete pump line and builds the end socket device, is applicable to steel form carrier crown sealing of hole.
Background technology
In underground engineering construction, tunnel adopts steel form carrier to carry out the formwork erection construction, and not stratified full section is built, and the conventional casting method of employing can not be closely knit with crown position concrete filling.
Summary of the invention
The utility model provides a kind of concrete pump line to build the end socket device, satisfies tunnel crown lining concrete and builds closely knit needs.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the concrete pump line is built the end socket device, comprise steel form carrier template face, first pump line, second pump line that steel form carrier template face is provided with, first pump line, second pump line lay respectively at the outside in the steel form carrier template face, steel form carrier template face inboard is provided with the reinforcement steel plate, first pump line and steel form carrier template face are provided with isolate steel plate between the outside, and stay bolt passes first pump line, isolate steel plate, steel form carrier template face, strengthens steel plate, second pump line is fixedly connected with them.Described second pump line is bolted to connection with the reinforcement steel plate.
Described second pump line is provided with plugging hole, and plugging hole is provided with bolt.
Described isolate steel plate is circular-arc, the both sides chamfering.
The beneficial effect that a kind of concrete pump line of the utility model is built the end socket device is as follows: isolate steel plate is circular-arc, is convenient to be adjacent to the steel form carrier panel, and both sides band chamfering makes things convenient for the later stage to remove.Employing connects into firm integral body with second pump line with strengthening steel plate than lag bolt, to avoid the distortion of steel form carrier form surfacing.The concrete pump line that the utility model provides is built the end socket device, finishes and builds back dismounting steel form carrier template face pump line in addition, is fit to very much tunnel lining concrete construction crown and builds.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model structure drawing of device;
Fig. 2 strengthens steel plate structure figure for the utility model;
Fig. 3 is the utility model isolate steel plate structure chart;
Fig. 4 is the utility model first pump line structure chart.
The specific embodiment
The concrete pump line is built the end socket device, comprise steel form carrier template face, first pump line 1, second pump line 2 that steel form carrier template face is provided with, first pump line 1, second pump line 2 lay respectively at the outside in the steel form carrier template face, steel form carrier template face inboard is provided with strengthens steel plate 4, be provided with isolate steel plate 3 between first pump line 1 and the steel form carrier template face outside, stay bolt passes first pump line 1, isolate steel plate 3, steel form carrier template face, strengthens steel plate 4, second pump line 2 is fixedly connected with them, described second pump line 2 with strengthen steel plate 4 and be bolted to connection.
On first pump line, 1 flange internal thread is set, passes reinforcement steel plate 4 by bolt and be connected with second pump line 2 with isolate steel plate 3.6 M20 internal thread bolts hole are set on first pump line, 1 flange, adopt 2～3mm steel plate to cover bolt hole.
12 φ 21mm through holes are set on second pump line, 2 flange, and pump line one side has 3 φ 28mm holes.
When building crown, pump line stops feed after being fed to constant voltage, with the bolt taking-up of 3 φ 28mm hole shutoff in advance on second pump line 2, in 3 Φ 25mm reinforcing bar patchholes, to prevent the concrete tenesmus in second pump line 2.Remove second pump line 2 then with pump line, remove second pump line 2 when waiting concrete and strengthen the bolt that the steel plate 4 and first pump line 1 are connected, second pump line 2 is removed near initial set down to the pump machine.Steel form carrier is removed isolate steel plate 3 after moving back mould, repairs the concrete aperture that the hole sealing device position stays.Isolate steel plate 3 is reusable.Being fit to very much tunnel lining concrete construction crown builds.
