FIG. 1 is a schematic structural diagram of the present embodiment;
FIG. 2 is an enlarged view of portion A of FIG. 1;
fig. 3 is a schematic structural diagram of another view angle in the present embodiment.
The reference numbers and corresponding designations in the drawings are: 1. the pipe jacking system comprises a hole steel pipe sleeve, 2 a pipe jacking machine, 3 a water stop rubber ring, 4 cotton wool, 5 a pressing plate, 6 bolts, 7 strip holes and 8 grouting holes.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1-3, the embodiment of the present application provides a pipe jacking receiving water stopping device for a water-rich sandy soil layer, which includes an opening steel pipe sleeve 1 and a pipe jacking machine 2 inserted into the opening steel pipe sleeve 1, wherein a water stopping rubber ring 3 is coaxially disposed on an end surface of the opening steel pipe sleeve 1, preferably, the thickness of the water stopping rubber ring 3 is not less than 20mm, so as to avoid leakage problem caused by the rubber ring turning outwards, the inner diameter of the water stopping rubber ring 3 is smaller than the inner diameter of the opening steel pipe sleeve 1, and a gap is reserved between the water stopping rubber ring and the pipe jacking machine 2, preferably, the gap is a circular ring structure, the ring width of the gap is not more than 50mm, the width dimension is convenient for leaking stoppage, cotton wool 4 is filled in the gap, a plurality of pressing plates 5 are evenly distributed on the water stopping rubber ring 3 in the circumferential direction, the pressing plates 5 are fixedly connected with the opening steel pipe sleeve 1 through bolts 6, preferably, the pressing plates 5 are trapezoidal structures and made of steel plates, the thickness of the pressure plate is not less than 10mm, so that the strength and the pressing requirements of the pressure plate 5 are met.
This stagnant water rubber circle 3 that stagnant water device is received to push pipe is fixed through clamp plate 5, can prevent outside upset, and stagnant water rubber circle 3's internal diameter is greater than push bench 2's external diameter, and reducible required precision to push bench 2 goes out the hole can fill in cotton fibre 4 from the clearance department and carry out the shutoff when push bench 2 goes out stagnant water rubber circle 3 back, also makes things convenient for the later stage to take out reuse with stagnant water rubber circle 3 simultaneously.
